Visit Tokyo Metro’s Subway Museum

— Amazing subway network in Metropolitan Tokyo and its development

T Metro- Logo x01.JPG      Tokyo’s subway passengers are now swelling to more than 10 million a T Metro- Outlook x01.JPGday that is almost the same with the population of Tokyo. And the routes count over 13 lines with more than 130 stations. This might be noted for unprecedented scale in the world.  The subway now became an indispensable commuting means and crucial public transportation for the people in Tokyo area. How these scales of subway network has been created and formed in history?  With T Metro- Outlook x02.JPGthis question, I visited Tokyo Metro’s “Subway Museum” in Tokyo this month.
The museum is located just adjacent place to Kasai Station on the Tozai Subway Line.  The museum which was founded in 1994 to introduce the development history of subway system in Japan, especially in Tokyo region. Now there now many real trains and railway equipment are exhibited aiming to publicize the activities of subway T Metro- history x05.JPGnetwork of past and present.  For example, the technology advancement of railway vehicle and drive systems, excavation technology in the underground construction work, and railway running operation and management.  In the exhibition, real vehicles, moving devices, interactive models and various diorama are abundantly used.  New subway operation and equipment methods, as well as previous history on the subway can be learned through the direct observation there.  The following is a rough introduction to the museum and development process subway network in Tokyo.

♣    The history of the subway that started in Tokyo

T Metro- Illust x19    The plan of Subway construction in Tokyo was started in 1910s.  It was said to begin as Tokutsugu Hayakawa, a businessman, realized the need toT Metro- history x03.JPG provide of subway system in Tokyo as an essential urban transport after observing London’s highly developed subway system. Afterward, he established “Tokyo Light Subway Co.” in 1917 to move forward the beginning subway construction with his initiative under this thought.  The plan had to inevitably face uncountable severe problems like financial and technology difficulties at the time of beginning. However, the construction itself could has been completed as the original plan after his tireless T Metro- Outlook x04.JPGendeavor. It was the first subway line constructed in Tokyo of operating in the route of 2.2km between Asakusa and Ueno in December 1927.  Later, it was extended to Kanda and Ginza, and then to Shimbashi in 1939.  This is the origin of the current Ginza Line. The real subway vehicle of being first operated in Tokyo is on display in the museum as a precious memorial asset, which is now designated as a “Japan’s T Metro- Railcar x11.JPGModernization Technology Heritage”.     The second subway in Tokyo was the Marunouchi Line, but the completion of it had to wait till the post-War period. This line was opened in 1954 between Ikebukuro and Ochanomizu of 6.4 km and eventually reached 27.4 km to Ogikubo station later.  These two lines became the most convenient transport and T Metro- Illust x06.JPGpopular means for urban people in Tokyo until the 1960s in paralleled with the other ground railway networks. The museum exhibits the real vehicles of Ginza and Marunouchi lines side by side as memorial objects.

<Subway advancement after the postwar rapid economic growth>

T Metro- history x06.JPGT Metro- Illust x13      Rapid economic growth in 1960s has vigorously promoted the movement of further expansion and improvements of subway network in Tokyo in order to respond strong demand for convenient urban transport, particularly in the wake of the Tokyo Olympics in 1964.  The two operation bodies, “Eidan Subway Network” (now Tokyo Metro) and Tokyo Govt’s “Toei Subway Network” have been responsible for this requirement at that time.

T Metro- Tech x05.JPG  First, Eidan Subway Network constructed the following lines, such as the Hidaniya Line in 1961 (between Minamisenju and Okachimachi, later extended Kitasenju and Nakameguro), the Tozai Line in 1964 (originally Takadanobaba and Kudanshita, later between Nakano and Nishifunabashi), and the Chiyoda Line in 1969 (Initially Kitasenju-Otemachi, later Ayase-Yoyogi-Uehara), 1974 Yurakucho Line (between Ikebukuro and Ginza, later Wako-shi and T Metro- Railcar x08.JPGShinkiba), 1977 Hanzomon Line (initial Shibuya-Futakotamagawa, later Shibuya-Oshiage) can be noticed.Toei subway Network has constructed several subway lines during this period, including the Asakusa Line (opened in 1960), the Mita Line (opened in 1968), the Shinjuku Line (opened in 1980), and the O-edo Line (opened in 1991).

The features of the newly constructed lines during this period were the actively create beneficial mutual service cooperation with T Metro- Railcar x09.JPGother ground lines (mutual entry line management) and facilitation of innovative vehicles in new designs and devices. They have also initiated further expansion of operation of railway lines.     From the 1990s inward, the subway network was more expanded with opening new routes between the Namboku Line (opened between Komagome and Akabane in 1991) and the Fukutoshin Line between Ikebukuro and Shibuya in 2008.

At present, the Tokyo subway lines have reached a total length of 304 km and has 13 and 130 lines with marking the largest scale in the world.  It would be amazing achievement that such bountiful subways lines T Metro- history x07.JPGhave been constructed during 90 years since the first subway was born in Tokyo. In addition, it has gained a great reputation that each of the lines work precisely in tandem and operates accurately in the designated time schedule. At the museum hall, a bronze statue of a pioneer Hayakawa is placed in commemoration and beside it a panel board describing history of development since the first challenge is on display there

♣   Evolution and transition of subway cars seen in the exhibition

T Metro- Illust x02.JPGIn the museum, several representative subway vehicles are displayed in real figures or by models.  The type of subway vehicles being operated in Tokyo was usually classified by digit numbers to identify T Metro- Railcar x04.JPGtheir style and features. The first subway Ginza line vehicle was named “1000 gata” type. This first vehicle of this Ginza line is exhibited in the museum using reproduction motif scene of Ueno Station. Visitors can examine this first type of vehicle with their own eyes there. This yellow body vehicle has characterized the rugged metal body, flame-retardant flooring, hanging drive system (spray type), automatic air brake, automatic door, punch type ATS T Metro- Railcar x01.JPG(Automatic stop). It is significant in terms of design and facility even it was the first challenging product of subway in Tokyo.
Next to it, the second Marunouchi line, 300 series 301 is also seen in the display. We can see the appearance of the vehicle being precisely the same figure at the time of T Metro- Railcar x02.JPGopening.       In addition, the other 1938 Ginza Line 100 (No. 129) vehicle is provided at different corner to invite visitors to inspect the inside appearance, driving structure, pantograph movement, and control unit by their own eyes.     The exhibit also shows the evolution of the structure and function of vehicles among the different types of cars used to work in the previous subway lines. According to the explanation, the carrying equipment was changing from the original bogie type to the steering bogies, the material was shifting from stainless steel to aluminum alloy, the driving method was also advanced from WN T Metro- Tech x01.JPGcoupling type to the direct drive motor, the control device was transformed to the electromagnetic chopper and VVVF converter, in addition, the current collecting method was also shifted to advanced pantographs. All these processes can be acknowledged in the technology information chart displayed in the exhibition hall with photographs and pictures. The recent development trend in linear motor was also introduced in the explanation board there.

♣   Underground excavation and its technology seen in the exhibition

T Metro- Illust x08.JPG       The most essential technology in subway construction would be how successfully build underground tunnels in the safe and efficient manner.  T Metro- underground x01.JPGThe advancement of drilling methods and technologies are shown in detail in the exhibits. The excavation method is usually classified into two types. One is “opening ground method”’ which excavates and constructs tunnel from the surface of the ground. The other type is the “shield underground method” which constructs underground tunnel by special drill T Metro- underground x08.JPGmachines like ship-worms move. The opening excavation method is relatively low cost, but it is difficult when there are structures on the surface.  On the other hand, the shield method is less constrained by the ground and soil conditions despite technically difficult and expensive.
In urban area, the deep excavation measures like shield method are essential because buildings are densely constructed, and many underground structures are busily intersected.T Metro- underground x04.JPG

The shield method is that special machines T Metro- underground x02.JPGconsecutively excavate tunnel by soil crashing cutters while the “shield (or box)” supporting the tunnel’s wall in the rear side already drilled , and the cutter machine sequentially is advancing the hole in the tunnel, and then move forward the shield and finally builds the final wall behind the shield.  In the present day, highly mechanized shield machines are used, and the walls are constituted of divided blocks (“segments”) to form structures.
T Metro- underground x10.JPG  T Metro- underground x09.JPG  In the museum, the state of the general excavation method and the shield method ones are reproduced by the scale model, and the huge surface of the shield machines which actually used is displayed there. For the example, the shape of rotating cutter head at the tip of machine, the fine blade (cutter bit) and roller cutter attached to the machine, the mechanics to carry the excavated earth and sand backward, the cylindrical block on theT Metro- underground x07.JPG dug wall, and others, as well as details of the forming process of segment structure.  These shield method technologies have greatly advanced recent days with facilitating GPS functions, sensors, drilling rigs and others. The technology development like it has made a great leap forward the construction of congested subway networks construction as a result. These are clearly observed in the exhibition.

♣   Past and present of operation management and control seen in the exhibition

T Metro- Illust x16.JPG       It would be common belief that the precise operation and control system are indispensable element to successfully keep accurate on-time operation and safety of the railways.
Japan’s railway management is highly reputed as the most advanced.  In the case of subways in Tokyo, it is crucial to perform careful management regarding daily T Metro- Tech x03.JPGtrain schedules, accurate monitoring operation and troubleshooting, when considering that millions of passengers get on and off every minute using dozens of various lines a day. For this reason, Tokyo Metro provides a specific “Integrated Management Center” which is conducting a computer-operated monitoring and operation control system without stopping 24 hour a day.  In the museum, a T Metro- Tech x04.JPGsophisticated simulator device which has been practically used is installed to introduce this control system. Thanks to this, you can understand the contents of actual operation management.
On the other hand, there are countless sample facilities are shown in the exhibition. They are a set of information transmission device for trains, monitoring and failure information system to monitor of malfunction vehicles, and automatic operation control, and other devices. All of them seem to bee the precious exhibits to acknowledge the safety operation of subway management.

♣   Current appearance of Tokyo subway and impression of visit

T Metro- Illust x17.JPG       As mentioned earlier, the Tokyo subway is proud of its achievement of more than 300 kilometers in total running length and supports millions of people in Tokyo every day. The museum is describing a lot about the function and technology of subway T Metro- Outlook x06.JPGsystem in Tokyo, such as what kind of technology is used, how the subway system has been developed so far, how the subway has been practically designed and constructed, how the underground excavation has been carried out, and how vehicle development has been done, etc.  However, looking at the current Tokyo subway network, it seems that many issues still remain when seeking further beneficence and development. First of all, Tokyo Metro and Toei T Metro- history x04.JPGT Metro- Illust x12.JPGSubway whether coexist as management entities, whether the operation, fare and route management are necessarily integrated, and whether platform and station safety are enough, and others. It could also wonder whether the mutual lines entry and coordination with private railways and JR lines are sufficient, even far advanced compared with previous T Metro- Illust x09.JPGtime.       At present, the renovation of subway lines is progressing with a rapid pace in light of the 2020 Olympics, which seems to be taking good steps to resolve the issues. I am looking forward to seeing the Tokyo subway several years later. In this sense, this visit to the museum was quite fruitful for me.

Visit Tokyo “Fire Museum” and probe Japan’s firefighting history

   Exhibit Firefight practice in Japan from the past to the present

Fire M- logo x01.JPG     There’s a unique museum publicizing Japan’s firefighting Fire M- Overview x02.JPGtechnology and history in Yotsuya-Shinjuku, Tokyo. This is called  the “Fire Museum” being set up in 1992 by Tokyo Fire Department.  I had a chance to  visit this museum recently.       It is  known well that big fires  have repeatedly assaulted Japan’s big cities and plagued Japanese people’s life many times in history.
     Japan’s housing structure is quite prone to the fire because they were predominantly made by Fire M- current x13.JPG wooden materials. WhenFire M- Illust x03 looking back to Edo and Tokyo  in the past,  a number of large-scale fires  occurred and burned down the entire cities claiming hundreds of thousands local populations.  On this problem, many measures have been taken in Japan, particularly in the metropolitan Edo and Tokyo area for minimizing damages in the past.      The museum deals with these fire and firefighting problem and tries to show what kind of disaster prevention measures have beenFire M- Edo x03 taken so far, what kind of Fire M- Illust x19firefighting system has developed in order to raise  disaster prevention awareness among local residence. Many exhibits are provided  to indicate this historical issues by showing real vehicles and equipment, dioramas, photographs and pictures, etc. It would be one of the best facilities to probe the history of firefighting and disaster prevention measures in Japan, especially in Tokyo area.

 

♣  Outline of Museum’s exhibition and its feature

Fire M- Illust x01.JPG     The museum has two major sections which introduce a history of Fire M- Illust x18.JPGfirefighting system for first one and the physical equipment and facilities for the other, such as fire engines and fire apparatus. In the history section, they are giving a comprehensive explanation on the early days “fire-extinguishing” system, transition of its mechanisms and tools in the Edo period as a system of ” Dawn” of firefighting practice. Next comes the introduction of modern firefighting system after the Meiji Era, includes the modernization of fire equipment Fire M- current x09.JPGand organization of fire institution, its prevention measures, and their roles expanding toward rescue works of natural disasters and so on.
In the second physical development section, they convey the significant enhancement of equipment in the past and present in the exhibition, such as they it exhibit various actual fire vehicles, ambulance cars, helicopters, in addition to the disaster brigades’ equipment which embodies the history and Fire M- current x01.JPGdevelopment of firefighting technology in detail.     The museum seems to provide a wide range of activities as well, including a disaster prevention campaign corner, a mini theater, and a library and training room for raising daily prevention awareness.
It seems to cover a wide range of useful exhibits that give live image of modern firefighting activities not only to fight against fires but also to engage large-scale disasters such as earthquakes, emergency medical care, and other roles.

♣   Firefighting in the Edo period seen from the exhibition-“Hikeshi”

Fire M- Illust x12.JPG      Most houses and buildings in Japan were made of wood, because of it Japan’s housing environment can easily lead to big fires, the especially Fire M- Edo x02.JPGdensely populated Edo’s urban area had always been vulnerable to the threat of large fires. As a matter fact, dozens of devastating large-scale fires had been frequently occurred in the Edo city and burn down whole urban area many times. Among them the “Meireki Fire” in the early 17th century was the most serious fires, which threw the Edo into a disastrous sea of fire and claimed hundreds of thousand people’s lives.
Fire M- Illust x19.JPG     After this, the Edo Shogunate had been beginning to take a major anti-fire urban measures and established systematic firefighting systems. For instance, the Edo government set up dozens of firefighting squads and created the fire extinguishing Fire M- Edo x04.JPGsquares “Hirokoji” in addition to the large-scale urban relocation measures.

In 1650, the first Edo’s “Jo-Bikeshi” (Stationed Fire squad) was organized in Edo, and in 1712, additionally “Daimyo Bikeshi”, a fire squad for protecting Samurai’s residence was also born in 1712.  However, it became clear being insufficient as an all-out firefighting to protect whole Edo city, because primarily it aimed at protecting samurai Fire M- Illust x14.JPGFire M- Edo x05.JPGareas only. Because of this, Shogun Yoshimune organized a town fire extinguisher “Machi Bikeshie” in 1718 consisting roughly 10,000 scale of own town people.  This town-based brave fire extinguisher has often been appearing in the “Kabuki” theater scene as a heroic character for Edo people people at that time.  Fire M- Illust x22    However, the firefighting method at that time was called “destruction firefighting system” and was a very primitive way basically aimed at breaking down surrounding houses of fire origins and preventing fires expanding further rather than on-site intensive firefighting system. The museum exhibits a diorama describing the scene of destructive fire and heroic extinguishing ways by this breaking method. Also, in this section, the disaster prevention equipment, water troughs, and hand-pumps called “Ryudosui” pump at the time were on display too. You can get a glimpse of the fire extinguishing at that time thereFire M- Edo x03.JPG.Fire M- Edo x06   In the Edo period, a lot of fire watching tower “Hinomi Yagura” were constructed in the various locations and variety of fire alert measures were taken, but when looking at the exhibition, we are inclined to see how difficult it was to prevent big fires in Edo at that time by such immature systems and technology in the past.

♣   Firefighting system after the Meiji modernization seen from the exhibition

Fire M- Illust x08.JPG      With the Meiji Restoration, ““Jo-Bikeshi” “Daimyo Bikeshi” Extinguishers were all abolished, and “Machi Bikeshi” system was reorganized into the Fire M- Meiji x09.JPGmodern extinguisher unit “Fire Department” under the Tokyo City government in 1872.  After that, the similar fire brigade system was spread to the other areas as a public institute nationwide as an efficient fire brigade (1894).  Along with this shift, the firefighting system and technology have drastically mechanized and modernized involving firefighting Fire M- Meiji x04.JPGorganizations, extinguishing methods, and fire Fire M- Meiji x05.JPGprevention equipment. This is clearly shown in the exhibition. For example, at the venue you can figure out how the firefighting had been done. For example, new extinguisher using steam pump, horse carriage fire engine, modern fire wear and tools, in addition the depiction by “Nishiki-e” picture (woodblock print) and other exhibits.  In the following time, the firefighting system is further improved and appeared fire engine cars.

Fire M- Illust x09.JPG    These series of evolution of firefighting equipment can be Fire M- Taisho x02.JPGseen in the exhibition as well.     Anyway, it was actually after the “Kanto Earthquake” in 1927 when the firefighting system has transformed from mere firefighting to more “disaster prevention” beyond previous boundaries. Their activities have been significantly expand to cover more broad field associated with natural disasters and changed their functions as well.    Exhibits show videos of fire brigade members working in the aftermath of the earthquake, Fire M- current x03.JPGincreasing number of fire engines and disaster response equipment, and the spread of organized activities well.   Moreover, after the War, fire brigades’ perceived works have enforced further in response to the rapid urbanization and rushed construction of high-rise buildings, even expected to cover diversified natural disasters. You can see the emergence of ladder cars for tall buildings, the start of emergency services, the activities of disaster rescue units, and the like there.

♣   Development of fire trucks

Fire M- Meiji x08.JPG      Among the modernized firefighting activities, the technology development is outstanding in the equipment field, particularly emergence of “fire engines” vehicle and its advancing functions can be noted. It was in 1924 when the first fire engines were introduced in Japan. They were the “Ahren’s Fox Fire Pump Car” (1924) and the “Stats Fire M- Taisho x01Fire Engine” (1924). These are on display in a museum along with other successive fire trucks. For example, Maxim fire pump truck (1929) and ladder trucks include Iveco Margis, Benz Mets, Isuzu ladder truck etc.  Regarding ambulances, a Toyota-made ambulance car was displayed on live conditions so that you can examine inside the car. You can also see a disaster prevention helicopter which used until lately as well.

♣   Development of firefighting equipment

Fire M- Illust x21.JPG   The evolution of firefighting equipment and tools since the modern firefighting system have been remarkable, and this progress can be found in the exhibition too.  The display of fire extinguisher costumes and tools of Edo period is quite interesting, as it reflects the features of firefighting at Fire M- current x08.JPGthe time. When it came to the Meiji era, their costumes changed to Western-style styles, and tools developed to the modern functional ones. And as it gets closer in the style to the present, so you can see many fire equipment that have become more scientific and technological advanced ones. It would be an evidence how technology has been cultivated to be able to qualify the fire equipment to be safer and effective fighting against extreme fire heat and Fire M- equipment x01.JPGflame.     The exhibition clearly shows that the firefighting organization and technology have been constantly progressing to fulfill an important role in the society through disaster prevention activities.

 

♣   Modern firefighter’s style in the exhibition

Fire M- current x04.JPG   One of the features of modern firefighting activities is that they play a role not only in firefighting but also in emergency and disaster response. One of the important pillars in this regard would be an activity of “disaster rescue squad”.  The major facilities to technologically support their activities were the advanced equipment such as “disaster helicopter”, “chemical fire truck”, “ladder truck”, “ambulance” Fire M- current x07.JPGetc. In the museum, the firefighting helicopter, which had been active until recently, is displayed as the main object on the rooftop and entrance hall, as well as the ladder cars and ambulances mentioned above. a large number of disaster rescue equipment are also exhibited there.      On the other hand, disaster prevention and awareness-raising activities Fire M- current x06Fire M- current x02.JPG proactively going to promote in recent year as a current movement by the Tokyo fire departments. The Museum provides a special socializing section of “Fire Prevention Lounge” which displays lots of fire prevention equipment at home, disaster preparing goods and board to explain how to use them and how to prepare for disasters. It has been shown that the current fire department is not only responding to complex disaster events but also focusing on how to prevent them in advance.

Last remarks

Fire M- Illust x15.JPG  I knew the existence of museum from before, but this was my first visit to look into the exhibition. It was amazing the facilities that is well Fire M- Edo x01designed and their exhibition in rich.     If we look at the Japanese urban environment, they are quite vulnerable to large-scale fires, and devastating fires always have been major concerns of our societies, because the general residential houses were dominantly wooden built in Japan.  In Edo or Tokyo, as a densely populated metropolitan city, even various fire measures have been taken since the Edo era, and a “fire extinguishing” organization has been well facilitated, but it couldn’t prevent dozens of big devastating fires and always gave huge damage to the Fire M- current x11.JPGFire M- current x12.JPGcity.  Even after the Meiji era, big fire was still a great threat to our society. In this situation a new fire department has been set up in Tokyo as government organization to modernize fire prevention functions and strengthen disaster preparations.  This “Fire Museum” looks emphasize the importance of disaster prevention by showing historical trends in an easy-to-understand format.
By this visit, I was able to learn a lot about the current disaster prevention activities, Fire M- Illust x10.JPGthe history of fire prevention systems, and the changes in disaster prevention technologies. It was a valuable visit for me to raise awareness of importance of disaster prevention. I felt I’d like to visit other facilities to inform us well regarding the natural disaster prevention measures if there are locations.

Visit the Hamamatsu Museum of Musical Instruments

— Taking wonderful music journey in the Hamamatsu Museum

H Music M- logo 01.JPG   While traveling to Hamamatsu City of Shizuoka Prefecture, I had a chance to H Music M- outlook 01.JPG visit the “Hamamatsu Museum of Musical Instruments”  The Museum is famed for the collection of treasury historical music instruments. The facility exhibits more than 1500 instruments from all over the world from Europe, Asia, Middle East, Africa, and Oceania with giving a good description on the history and features. It’s fun to be able to look into these world instruments, including various traditional folk instruments, not only Western modern instruments all togetherH Music M- outlook 02.JPG. The exhibition  puts particularly highlight on the beautiful instruments of Asian characters, treasury European instruments, unique form instruments of Africa and Oceania. They seem to be reflected their significant cultural diversity, tradition and their own history.  The collection of Japanese instruments is also impressive.  Additionally, theH Music M- Illust 05.JPG piano collection is quite significant as Hamamatsu, where the museum located, is renowned for a major production site of piano in the world. A number of characteristic pianos produced by Japanese makers are on display, along with the famous historical pianos in Europe.   It was really good chance being familiar with variety of music instrument around the globe.

 

♣  Overview of the museum exhibition

H Music M- Illust 13.JPG    The exhibition is categorically divided into several regional zones.  Asian zone displays 420 pieces of characteristic instruments, like Indonesian Gamelan and other traditional instruments. In the European zone, about 360 pieces of historical pianos, flutes and violins, and others are exhibited. In the Africa and Oceania zones, roughly 190 pieces of H Music M- outlook 04.JPGtraditional percussion and stringed instruments are on display, and in the South and North America about 150 instruments, like marimba are placed.  Also, in the Japan zone, we can see 200 pieces of legendary music tools, such as “Gagaku” instruments and other popular folk instruments like “Taiko” (Japanese drum), “Shamisen” (strings), “Koto” and others. Various organs and pianos instruments that H Music M- Illust 03manufactured by Hamamatsu since the Meiji era are also appeared in the special corner, including electronic musical instrument like synthesizers and electronic organs.
It would be quite precious that such a big number of instruments are intensively collected all together in a music museum. The collection of each zone are roughly as follows.

♣  Stringed instruments and regional features seen in the exhibition

H Music M- Illust 10.JPG First, we’d like looking into the feature and history of stringed instruments, Violins and cellos that born and developed in Europe would H Music M- A instrum 03.JPGbe the most popular stringed sound instruments now. But the origin of this string instrument is actually very old and diverse in history. For example, a kind of old “harp” is appeared 3,000 years ago in Egypt. Finger plucked string instruments were also found in the ancient oriental world from thousand years ago.  For example, rubbing H Music M- A instrum 04.JPGsound string instruments of Arab people called “Rebec” became popular in the middle ages. The bowed instruments such as Chinese “Erhus” and Mongolian “Morin khuur”, and unique guitar “Sitars” in India were brother and sisters of the same origin of ancient origin of instruments.  It is said that these instruments were brought into Japan through the continental Silk Road route in the long time ago. They H Music M- A instrum 05.JPGH Music M- A instrum 07were seemingly transformed into traditional instruments like “Biwa”, “Koto” and “Shamisen” etc. in the later period in Japan.   These instruments were evolved and expanded in the modern Western world too, and they became widely performed in the concerts of the European court music circles in the 18c and 19th. Since then, a quite number of variations of string instruments were produced and loved by worldwide population in modern societies, particularly in Europe. 

 So we can see a variety of modernH Music M- A instrum 08    H Music M- A instrum 06 string instruments in European zone. such as violin, cello, guitar and others. On the other side, traditional instrument like Sitars,Morin khuur, Chinese Erhu are well found in Asian zone, variety of banjo, binnbau are also shown in South America zone.  Japanese folk instruments like Koto, Shamisen and Biwa etc. are orderly displayed in the exhibition too.

 

♣   Percussion instruments lineage and its features seen in the exhibition

H Music M- Illust 07.JPG        When looking into the origins of percussion instruments, people say that these were originally created for the purpose of festivity H Music M- outlook 05.JPGand magic practice or for distant communication among people. But the instruments were gradually becoming used for pleasures and music plays. Therefore, initially shape was gongs and drums in the traditional style and they were gradually evolved in shape and sound.   In Asia and Africa, the ethnic percussion instruments are pretty popular among people and similar shapes were shared in the many regions.H Music M- A instrum 14.JPG

 

 

 

This is shown in the museum exhibition very well. There are variety of percussion instrument are found in the exhibition in the corner. For example, Indonesian Gamelan, Chinese Gongs, Korean Chango, Indian Tabla, Turkish Darabucca drums, and Xylophone-shaped Anklon made of bamboo in Southeast Asia.

H Music M- A instrum 11.JPGH Music M- A instrum 12.JPGH Music M- A instrum 10.JPG

In Africa, there are a variety of ethnic percussion instruments such as Ngoma, Kpanlogo Krin, and others many in exhibition.H Music M- A instrum 13.JPG

Meanwhile, in the European zone, modern percussion instruments, like Timpani and Dum sets, which have performed in orchestra concerts, are shown in the exhibition too.

 

♣   Wind instruments lineage and its features seen in the exhibition

H Music M- Illust 19.JPG      Wind instruments are a generally quoted the instruments that create sound by breath vibration in a tube. The origin of this instrument is H Music M- outlook 06.JPGbelieved to be quite old.  It had been widely played by people for long time at religious ceremonies, festivals, entertainment, etc. They were using bones, horns, shells, trees, plants, and many other available materials according their places. The distribution of the wind instruments is geographically pretty broad in the world.  When it refers to the modern performing wind instruments, European ones have predominant position and spread to the whole world because they were developed as the performing art in the concerts and theaters in the 19th and 20 century communities and became produced in the manufacturing industries.

<Exhibits of European modern wind instruments >

H Music M- A instrum 16.JPG    In the museum, the modern wind instruments of the European Zone account for the largest number of exhibition and boost the most diverse of H Music M- A instrum 17.JPGinstruments among the exhibition. First, woodwind instruments since the Renaissance era such as flutes, oboe, bassoon and new type of clarinet are found in the exhibition. For brass instruments, it shows the items, such as some style of trumpets with ancient characters, Trombone, Tuba, and so on which had H Music M- A instrum 19.JPGbeen produced in the period of the Bourbon dynasty in 18 century.
These instruments have been drastically evolved while changing the shape and quality of sound in previous many years to present.  We can clearly observe these changes in the exhibition as well as enjoy the current shape and sound at the museum.

H Music M- A instrum 32.JPG     On the other hand, there are many traditional folk wind instruments being found in Asia and Africa too. This is well reflected in the collection of exhibition items.  Especially, among the folk wind H Music M- A instrum 15.JPGinstruments, the “Didgeridoo”, an indigenous Australian instrument, is quite famous as “the oldest wind instrument in the world”. This instrument attracts many visitors in the museum for their unique shape and mysterious sound. In addition, Africa’s Skele and South America’s Ocarina and Sambonia are famed collection of wind instruments in the exhibition in the museum.

♣   Lineage of  keyboard instrument like piano and harpsichord in the exhibition

H Music M- Illust 16.JPG      The collection of pianos and harpsichord instruments looked quite diverse in the exhibition.  They are categorized as keyboard H Music M- A instrum 22.JPGinstruments as they create sound by operation of a keyboard for music.  Of these, harpsichord that holds similar shape and operation with piano became quite popular in 16th century Europe.  Around this period, a mechanical engineer Cristofoli of Italy refined this harpsichord and invented piano in the early 18th century. After H Music M- A instrum 23.JPGthat the piano was developed pretty fast and the current shape of piano was born by adding several dynamic sounding systems in the keyboard. Since then, piano has become the most influential instrument in Europe,

In the exhibition, we can see many classical instruments of harpsichords and H Music M- A instrum 20.JPGpianos made in the 18th and 9th centuries. For example, visitors can appreciate the magnificent harpsichord of the Bourbon dynasty in France, the Pleyel Forte piano in the 1830s, and the Graf of Vienna piano in the 1820s.  Another highlight is the Steinway’s piano series as the masterpiece products.

On the other hand, when the piano became H Music M- A instrum 21.JPGwidespread musical instruments in the 19th century.  The piano production technology remarkably progressed responding to these trends and became possible to produce massive scale of quality pianos industrially. In reflecting these trends, vertical upright pianos are born for home-use beside for the theater use.
Meantime, the Museum allocates a large space for the exhibition of various Japanese H Music M- outlook 07.JPGpianos manufactured by these manufacturers, along with classical foreign pianos. Because the industrial manufacturers, particularly Yamaha and Kawai in Hamamatsu, have been producing a huge volume of piano by their industrial skills.  It seems valuable in looking into the development history of piano in world including Japan in the exhibition.

♣   Feature of Japanese music instruments and the world in the exhibition

H Music M- outlook 04.JPG        Nearly most of the distinctive Japanese musical instruments are found in the Japan Zone. For example, “Ohdaiko” drums used in festival, “Kakko” (braces, “Sho” ,and “Shichiriki” used in Gagaku in ancient court music concerts, “Ryu flute”, “Shakuhachi” flute from the Edo period music, “Biwa” from the Nara era, and several style of “Koto” (Japanese harp), like “Yakumo koto”, “Two-stringed koto” and “Suma koto”, “Shamisen” for people’s performing arts, trumpet like “Horagai” for trainingH Music M- A instrum 28.JPGH Music M- A instrum 29.JPGH Music M- A instrum 27.JPG
mountain monks, Satsuma folk instrument “Gottan” and “Ryukyu sanshin”, and many others. They are really excellent collection to review Japanese performing arts.  It’s really significant exhibition that reminds us how such a variety of Japanese musical instruments have been developed and handed down in the historical context with the broader world.

♣   Japanese Western musical instrument zone

Hamamatsu’s development and exhibition of the musical H Music M- A instrum 33.JPGinstrument industry-

It seems necessary to touch on the roots of Hamamatsu instrument industry related to the museum exhibition. The Hamamatsu City is advocating the H Music M- logo 04“Town of Music” as mentioned earlier. It might H Music M- history 01.JPGbe due much to the concentration of big instrument manufacturers such as Yamaha, Kawai and Roland.  The origin could date back to the early Meiji era, when Yamaha’s founder, Torakusu Yamaha, first produced music organs in Hamamatsu region.  After winning an award for organ instrument product at the 3rd National Industrial Expo in 1890s H Music M- history 03.JPGYamaha began to produce piano by establishing the “Yamaha H Music M- history 02.JPGMusical Instrument Factory.”  Soon later, in 1897, the company was renamed to “Nippon Gakki Manufacturing Co.” and began producing organ and upright pianos.  This was the beginning of Yamaha’s music business operation today.  In the H Music M- history 09.JPGH Music M- history 06.JPGmeanwhile, Kawai Koichi, who had been working at the Yamaha, retired it and started manufacturing pianos by setting up the “Kawai Musical Instrument Research Institute” independently in 1926.  Today, Yamaha and Kawai now boast the world’s largest piano producers.H Music M- history 04.JPG
In the museum exhibition, we can find many music instruments that they have been produced in the companies.  For example, a foot-operated reed organ (Nippon Gakki in 1907), an upright piano (Nippon Gakki in 1897), and a grand piano (Kawai Musical Instruments in 1927).  There, the history of Yamaha and Kawai is reflected.

 <Exhibition of electronic musical instruments>

H Music M- Illust 20.JPG      As for electronic musical instruments, current leading-edge instruments in the world and Japan are broadly collected in the exhibition, including synthesizers, rhythm machines, electronic organs, H Music M- A instrum 26.JPGand electric guitars.  For example, Electone D-1 (Nippon Gakki Co., in 1959), Electric Guitar SG-7 (Nippon Gakki Co., Ltd. in1965), Synthesizer System 700 (Roland in 1976/), Casio Tone 201 (Casio in 1980 /) etc. The electronic musical instruments which have passed over 100 years’ history showing new musical instrument styles. We observe its development in the exhibition in this corner.

♥  Remarks after visit

H Music M- Illust 01.JPG        Although it was a short time stay in Hamamatsu, I enjoyed very much the visit of “Hamamatsu City Musical Instrument Museum” and could appreciate rich contents of the music world,  I have H Music M- outlook 03.JPGexperienced visiting various music performing concerts including orchestra ones several times, but I haven’t had enough knowledge about musical instruments. So, through on this visit, I learned much about the origins and characteristics of various musical instruments and its evolution.  In particular, I could have strong impression by observing exhibited instruments how diverse the cultural background of these instruments, their relevant history, in addition to the vast distribution of folk instruments from H Music M- history 07around the world.
It is really amazing such huge collection of historic music instruments that the Museum have been accumulating from all of the world, particularly focusing on the integrating themes and concepts. I felt the Museum is really a treasure of the Hamamatsu City as the Town of Music”.

Visit Tokorozawa Aviation Museum in Saitama

  • Describing the dramatic history of aviation industries in Japan and world

Last month, I went on Aviation M- Logo x01.JPGvisit to an aircraft museum in Tokorozawa, Saitama Prefecture, Aviation M- outlook x01.JPGnamed “Tokorozawa Aviation Museum”.  It is because I heard many historic aircraft are exhibited there. The museum was said to be established in 1993 on the Aviation Park Tokorozawa in commemoration of the Japan’s first flight conducted there.  In the museum we can see a number of countable real and replica airplanes that Japan has been developing or introducing until now. Aviation M- outlook x03.JPG It would be an ideal place for reviewing the history of aircraft industry in Japan.  The museum provides the extensive explanations on the evolution of world flight technology, the background of Japanese aircraft development, as well as the previous function of Tokorozawa airfield.  Flight simulator and playground etc. are also provided there so as the people can actively learn on the real action of flights.  It is really interesting Aviation M- Illust x06.JPGfacility to offer the outlook of real aircrafts, such as, “Henri Falman “ that conducted the first flight in Japan, “Type 91 fighter” designated as an aviation heritage, the first post-war domestic jet aircraft “T-1B training aircraft”, the first passenger aircraft “YS-11” exhibited at the Park side, and so on.

 

♣    Overview of Tokorozawa Aviation Museum and its exhibition

Aviation M- Illust x05.JPG    In the large exhibition hall of the “Museum”, which is built as the main facility of the Tokorozawa Park, there are several sections are allocated.  They Aviation M- outlook x04.JPGare a “Parking” lot that displays various aircraft, a “Hangar” place that describes the history of aviation, and a “Lab” area that explains aviation science.  At the second floor, it found a display panel with showing the history of Tokorozawa Airfield, a reproduction of the flight control room, and the flight experience corner where It is possible to use a simulator.

Aviation M- AirPlane x02.JPG    A number of the famed historic important aircrafts are exhibited at the “Parking” lot, such as the “Kawasaki KAL” developed in Japan, the “T-34 Mentor” US reciprocity training aircraft, the “Schinson L-5E” light plane, and the “Fuji T-1B”, a training aircraft for the Air Self Defense Aviation M- AirPlane x03.JPGForce. ”, the “ H-19 ”, military helicopter“ H-21B-V-44 ”, and many other machines are located there. There found a replica of the “Meeting Type No. 8” produced by Japan in 1910s, and “Type 91 Fighter” (Aircraft Heritage Certified No. 1) that designated as a historical heritage in Japan too. These are all valuable objects implicating the development of history of Japanese aircraft.
Furthermore, at a corner of the exhibition hall, when I visited, there was a two-Aviation M- history x06.JPGwinged “Henri Falman “ was exhibited, along with a portrait of Captain Tokugawa who made his first successful flight in Japan in 1911.  This is an exhibition that really seems to reflect the beginning of Japanese aviation history.  Visitors can also observe a full-scale replica of the “New Paul 81E2”, which was produced Aviation M- history x02.JPGby “Newpole” in France and used as a training machine in Japan in the 1920s.     It is also attractive to see the airplane’s history and technology in the “Research” corner and to visit experimental equipment to understand the principle of flight among the many exhibitions.

♣    The dawn of Japanese aircraft development seeing from the exhibition

Aviation M- history x01.JPG      As seen in the exhibition, since old time, the dream of flying “sky” had been grabbing the heart of many people.  In the 16th century, Leonardo Da Vinci designed a kind of prototype of “airplane”, and in the 18th century, France’s Montgolfier brothers experimented it with Aviation M- history x03.JPGhot air balloons. Then later, Lilienthal from Germany had repeatedly produced and tested glider planes to fly.
At the next stage, American “Wright brothers” successfully invented the first powered airplane and let it fly to sky in 1903. It’s said that flight became the starting signal of the aircraft era today.  The longing for fly in the sky had been also Aviation M- history x04.JPGstrong in Japan, and there found a record that Shimazu Genzo (a founder of “Shimazu Mfg”) lifted a balloon in the early Meiji era. Besides, Ninomiya Tadahachi made a bird-like flying body in 1893 and succeeded first in the test flight at that time. It seems intriguing that a scale model of this Japan’s trial plane is displayed in the museum and giving brief information about it.

<The first flight in Japan>

Aviation M- Illust x01.JPG     However, in Japan, the first successful flight of Aviation M- history x05modern aircraft was in 1911 when Captain Tokugawa made a test flight at the Yoyogi Army field in Tokyo. He also succeeded in flight of the “Henri Farman” (made in France) at Tokorozawa Airfield in the same year. In commemoration this event, a real reproduction machine of a Farman machine is installed in the venue as a memorial exhibit. It’s fascinating to be able to look at the machine in our eyes.    Anyway, since then, Japan was earnestly beginning the development of aircraft for military Aviation M- AirPlane x15.JPGpurposes, because the aircraft was realized as a major strategic tool during the First World War.  And like other countries, Japan had transferred strategic aircrafts from the United States and Britain, beside started challenging its own aircraft development. This situation is well illustrated in the various actual and replica aircraft shown in the museum.  Among these aircraft, the most notable ones are the “Kai Shiki No. 19” (1911) and “Kyuichi Type Fighter” Aviation M- AirPlane x07.JPG(1927), which were said to be developed by Japanese engineers while applying Western aviation technology. However, it has to be notified that a great number of aircraft that had deployed at that time in Japan were machines imported from European countries. In addition, it was found only a few civilian purported aircraft being available in this initial period, and even the designing skills of aircraft was rather poor if compared with Western countries.

♣    Aircraft industry before and after the Pacific War being visible in the exhibition

Aviation M- Illust x14.JPG     However, during the 1930s, the government strongly addressed the capacity building of aircraft manufacturing because of recognizing its Aviation M- AirPlane x10.JPGstrategic importance.  Among them, Nakajima Aircraft (now Subaru), Mitsubishi Shipbuilding (later Mitsubishi Aircraft, now Mitsubishi Heavy Industries), Kawasaki Aircraft (now Kawasaki Heavy Industries), etc. were nominated as aircraft manufacturers and vigorously launched in the businesses of developing domestic aircraft and engines. But it was soon revealed that major advanced technology had to depend on strong technical support or getting licensed from Europe and American manufacturers,

Aviation M- AirPlane x12.JPGAviation M- AirPlane x13.JPG      Meanwhile, toward the Pacific War, Japanese government began to take strong initiatives to foster the aircraft industries and promoted the aviation technology seeing increasing demand of military aircraft.  As a result, their technological competence improved quite fast supported by the government and a great commitment of airplane makers.  Since then, the manufacturers were producing a large number of excellent aircraft and fighters. The “Zero-type” fighter plane (so-called “Zero Sen” fighter) is listed Aviation M- AirPlane x08.JPGas one of the good examples of technological culmination in this period.  Among these war planes, a real aircraft the “Type 91 fighter” (biplane type 4 fighter, produced by Nakajima Aircraft in 1931) is exhibited at the Museum, and this is designated as an important aviation heritage in Japan.  It would be showing the development of Japanese aircraft building which reached a temporary apex, mainly for military use aircraft during war time.

 

♣    Development of post-war aircraft industry as seen from the exhibition

Aviation M- Illust x09.JPG     The defeat of War in 1945 had brought the total destruction of  aircraft industry in Japan.  In addition to the eradication of airplane factories and Aviation M- AirPlane x04.JPGairfields, the occupation forces had forced Japan to ban of engaging in any aircraft development, research, and operations related the aviation field, in being fearing to revive the Japan’s military power.  And these regulations didn’t lift until 1957.  Then, it seemed to be quite hard to recover Aviation M- AirPlane x17.JPGthe gap and the technical behind was clear in this period.  Due to this, Japan had to be stayed only in licensed production of US-made aircraft or Aviation M- AirPlane x05.JPGrepairing business for the Defense Agency and other institutions.  In addition, the aircraft industry in the world had already entered the era of large scale flight, diversification of models, and sophisticated jet aircraft world. So, Japan was pretty hard to catch up soon on the international levels.  Furthermore, for the domestic manufacturers that had been exclusively focused on military aircraft, it was a real challenge to quickly shift to the commercial purpose aircraft.
Aviation M- AirPlane x14.JPG     Anyway, the visitors can observe the many samples of post-war military and civilian aircraft in the exhibition of the Museum. For example, the military helicopters the “UH-1 Iroquois”, the “H-21B”, the V-44, which were manufactured in U.S. or UK for deployment to the Japan’s Self-Defense Forces (SDF), and other machines can be seen there.   Among them, it is significant that the SDF’s “T-1B training aircraft” produced by Fuji Heavy Industries Aviation M- AirPlane x01.JPGbecame the first post-war domestic aircraft installed the jet engine. The plane is displayed in the hall with its engines at that time. Although it is not honestly seen in the exhibition, it is true that independent development of aircraft has gradually progressed through the development of “PS-1 flying ships “ and “C-1 transport aircraft” which supplied to the SDF.

<Development efforts of producing Commercial aircraft in Japan>

Aviation M- Illust x07.JPG      On the other hand, as it mentioned, it seems to be very difficult developing a commercial passenger airplane soon because of the lack of experience.  However, the government, which anticipated an increasing demand for commercial aircraft, established the Japan Aircraft Manufacturing (Nikko, NAMC) in the 1960s.  With this company as the technology center, Japan has mobilized many aircraft manufacturers and engineers who had been involved in the aircraft development before the War. And they tried to explore the way to produce Aviation M- outlook x02.JPGa new commercial passenger plane. The achievement was the first passenger aircraft “YS-11” developed by Japanese manufacturers after the war. The planes have been produced more than 180 units by 1973, and despite being in trouble, it had been operated for a certain period as the only domestically produced passenger aircrafts.  The actual aircraft of this YS-11 was on display at the corner of the Aviation Park in Tokorozawa where the museum is located.

♣   Current initiatives in the aircraft industry as seen from the exhibition

Aviation M- Illust x04.JPG    Although it couldn’t attain the originally set goal, the development of technology showed in the YS-11 production and also the aircraft “C-1” had played significant role for deepening knowledge and skills about aviation Aviation M- AirPlane x18.JPGAviation M- AirPlane x19.JPGindustry. For example, Fuji Heavy Industries has produced a “T-4 training aircraft” equipped with an F-3 engine, and Kawasaki Heavy Industries has succeeded in introducing a “CX transport aircraft “equipped with turbo engines. However, the development of civil aviation field hasn’t still kept up enough with the world first class business trend.  It’s also said that the major manufacturers couldn’t enough beyond the stage of the licensed production and partial participation in the joint Aviation M- AirPlane x06.JPGprojects of the major overseas aircraft producers.     Recently, however, Japan has begun to work on the competitive medium-sized passenger aircraft businesses by utilizing the previously accumulated technology.  There are several development projects such as Mitsubishi Heavy Industries’ MRJ and Honda Business Jet is going on in the business now.  In the exhibition, the sample machine of “Hondajet” is on display in the hall for trying to show this new trend.

Remarks after visit

Aviation M- Illust x08.JPG    Anyway, It was pleased that I could visit an aviation museum like Tokorozawa Aviation Museum for the first time in my experience.  There I was able to able to learn many about the aircraft technology and the Aviation M- outlook x05.JPGhistory of aviation in world and Japan. In particular, through the viewing real aircraft, I’ve got a fresh knowledge about the origins of flight technology, evolution of flight science and the related technology, as well as a total history of world and Japanese aircraft development. It was a really good chance for me to understand the aviation industries and its history.  I’ve heard that there are many other aircraft museums in Japan, including an aviation museum in Narita.  So, I’d like to visit these facilities before long.

Visit Nissan’s Engine Museum in Yokohama

Looking into the evolution of Nissan’s automotive engines and the footprint of the company

Nissan E-  Logo x001.JPG     Nissan seems to be facing a sort of management challenges lately, butNissan E-  Overview x001.JPG it’s sure to be playing a significant role in the Japanese automobile industry.   In particular, Nissan is regarded to lead the advancement of automobile technology industry in history. In this mind,  I visited the Nissan’s “Engine Museum” in Yokohama recently because I’ve heard there’s an unique museum showing the technological Nissan E- engines x002challenges of automobile, especially on their engines. The museum was said to be opened in 2003 in commemorating the establishment of Nissan’s first assembly factory “Yokohama Plant” in 1934 using its former headquarter building.  There are many historical automobile engines exhibited in the museum with extensive commentary on their technology development process, as well as on the company history. And there installed many photographs and panels which Nissan E- cars x002indicates the technology foundation and development of Nissan Motors.  Then, the visitors can easily trace the company’s turbulent  footprints that had experienced  countless technological challenges along with long  history of the company. The exhibition seems to be quite instructive to understand the historical development of Japan’s automobile industry as a whole not only for the Nissan itself.

♣    Overview of Engine Museum Exhibition

Nissan E-  illust x010.JPG        The museum main subject is the Nissan’s automobile production technology, especially on the development of engine technology, but Nissan E-  engines x004.JPGalso, focuses the history of the company development itself.
In the engine exhibition corner, it displays many valuable historic engines in row from the early “7-type engine” (1935), new type engines in 80s, energy saving diesel engines in 90s, to the currently developing variety of EV engines.  Nearly 30 types of Nissan engines are exhibited there with detailed explanations.  In particular, the new EV engines are proudly exhibited with Nissan E- engines x003providing real cut models which s suggest Nissan’s decisive commitment to the development of EV engines from an early stage.     The exhibition also shows how the engine is performed, what’s internal structure they have, how steering, and suspension works in the vehicles, etc., too. In addition, they demonstrate the recent functional engines which produced by under the unique concept by Nissan. Nissan E-  history x009.JPG

       In the history corner, the museum displays the Nissan’s company history since the establishment of original firms in 1910s and the historical background that was gradually evolved to the latest Nissan Motors, along with the transforming scene Nissan E-  engines x011.JPGof Yokohama factory itself, by putting lots of photographs, chronology and panels, It seems to be also valuable for reviewing Japanese automobile history as well.     Furthermore, in the entrance hall, Nissan’s historic model car “Datsun” is exhibited as memorial figures, in addition to the latest model of the advanced which shows its EV car Leaf” current challenges. They seem to indicate Nissan’s strong commitment of automobile technology as well as long engagement to the automobile businesses.

♣    History of Nissan Motor Co. that conveys a footprint of Japanese automobile industry

Nissan E-  illust x001.JPG         Nissan Motor was actually founded in the 1930s, but its prehistory canNissan E-  cars x003.JPG be traced back to the decades ago.  The automobile industry in Japan was said to be started by making a simple cart-like car “Tackley” by Yamaha Torao in 1907.  And in 1911, Hashimoto Masujiro manufactured his own car “Swift” Nissan E- history x001Nissan E-  history x004.JPGusing imported car parts from UK at his newly established company “Kaishin Sha”, and consequently produced “Dat No.1”at his factory. This is believed to be the original firms of later Nissan Motors.
However, the production and technical level of Japanese makers were quite poor at that time, in this circumstances, Ford and GM had aggressively entered Nissan E-  history x015.JPGJapanese market and fully monopolized the car production throughout in 1930s. The Japanese industrialists who were worried about this situation wanted to establish automobile solid foundation in Japan. Among those, a businessman Ayukawa Gisuke acquired “Dat Automobile”, which had changed name from the “Kaishin-sha”, and launched “Datsun Motor Co.” in 1932.   Afterward this company merged with “Ishikawajima Co. (later IHI)” and formed “Automobile Mfg Co.”. Then finally this company was transformed its management and officially founded as “Nissan Nissan E-  history x012.JPGMotor Co.” in 1934.  The Nissan’s “Yokohama Plant”, where I visited, was built as its main automobile assembling plant in 1935.
In this way, the born of Nissan Motor was proceeded under the somewhat complicated process, but the Museum described well the history in detail by the panels displayed in the hall.     In the meantime, the government began to take strong initiatives to foster domestic car makers by enacting the “Automobile Manufacturing Business Law (1936)” because they were worrying about the dominant position of US companies in Japan.  Reflecting to this trend, Toyota entered car production, and Nissan has also launched full-scale car production.Nissan E-  history x017.JPGNissan E-  history x016.JPG

The particular important matter was that the government began to order lots of military trucks to major Japanese manufacturers in order to activate domestic production and technological innovation in automobile production.  In addition, the particularly important matters were said to be the engineering capability nurtured in this period. That is, the engineers who were engaged in designing of military aircraft and truck engines during this period had Nissan E-  engines x013.JPGcontributed of building post-War automobile industry by effectively applied their acquired technology and skills.  This movements are thought to have certainly played an important role to build the technical foundation for leading the strong development of automobile production in Japan as a whole. Nissan has also grown up as one of the main manufacturers in this movement.     This development history process is detailed in the exhibition.

♣   Development of Nissan Motor before and after the War

Nissan E-  Logo x002.JPG      In the post-war period, the Japanese automobile industry has been Nissan E-  history x010.JPGrapidly reviving thanks to the special procurement from the Korean War, and Japanese automobile companies actively carried out the large-scale renewal of plants and mechanical modernization. In addition, around the 1950s, Nissan E-  history x005.JPGthe government strongly urged the domestic manufacturers to apply advance technology from the Europe and US automakers aiming to upgrade automobile industries as recognizing their technology was still immature.
Responding to this policy, Nissan practiced a technical tie-up with Austin (Isuzu for Hillman, Hino for Renault, Toyota gone for its own line), and actively pursued the line of improvement of facilities, innovation of Nissan E-  history x014.JPGproduction system, and scale up of the production plants.      Then, later in 1960, Nissan absorbed the “Minsei Diesel”. and merged additionally with a main passenger car maker “Prince Automobile” in 1966. Since then the company became called the current Nissan Motors.  During around this period in general, it was Nissan E-  history x018.JPGreported that the automobile industry of Japan was able to achieve the significant improve in quality by introducing American-style quality control and scientific management methods.  Meantime in 1961, Nissan established a full-fledged passenger car production plant “Nissan Oppama Factory”.    Number of passenger cars such as Blue Bird (1962-), Sunny (1973-), and luxury cars Cedric (1987-) were born there, which Nissan E-  cars x005.JPGwere valuated as prestigious cars in the market, were introduced one Nissan E-  cars x004.JPGafter another.                 The exhibition provides a detailed explanation of this consecutive process from the strengthening of Nissan’s production system to the further the evolution of its technological advancement in this period. It seems to convey some parts of the development history of rising automobile industry in Japan as well.

<Management challenges for Nissan Motors>

Nissan E-  illust x009.JPG    However, due to the failure of the marketing strategy in addition to the collapse of the economic bubble around 1990,  Nissan’s management crisis Nissan E-  history x007.JPGabruptly came to be appeared, and  the company has to seek the management alliance with Renault since 1990s. After that severe restructuring policies were taken by hand of Renault President Ghosn (“Nissan Survival Plan”).  As a result, the finance condition was improved quickly, but the production system itself was greatly downsized,  However, in the 2000s, utilizing the recovering financial situation, the company began to take Nissan E-  history x008.JPGvigorous measures to expand production system, and adopted the promotion policy of EV cars with applying the previously accumulated technological ingenuity. However, the negative side of the Ghosn management was emerging in the late 2010s, and it can say that the company’s foundation began to be shaken again since this period.

Nevertheless, the Nissan’s immovable posture of strong technology commitment seems to be persistent and again began to challenge new areas of automobile making now as shown in the electric vehicles, for example. Nissan’s new Nissan E-  illust x006.JPGchallenge to advancing “electric cars” and “autonomous driving” technology is well indicated in the exhibition. It would be particularly outstanding features under the latest circumstances that the automobile world is shifting fast and steadily to the environment friendly and safety conscious automobile making. The exhibitions don’t touch much about the recent management crisis period, but the strong commitment to the technological advancement was well informed.

♣   Nissan engine’s advanced features and EV car initiatives

Nissan E-  illust x012.JPG    As I mentioned earlier, the Nissan’s real automobile engines are displayed with broadly covered in the Museum exhibition hall along the Nissan E- engines x005line of producing years reflecting the evolution of engine technology. First, we can see the “7-inch” engine produced by “Dat Automobile Mfg.” in 1935 which was said to be a quite innovative at that time though the capacity was rather small like 700cc and structurally simple. After the War, Nissan firstly produced the “C-type” engine (1953). This was an approximately 1000cc capacity with an OHV system produced in a technology alliance with Austin in the UK.
Nissan E-  engines x006.JPGThe first “Sunny” car was equipped with the “A10 type” (in 1960s), and the engine “U20 type” was installed in the sports car “Fairlady”. We can closely observe them in the exhibition with detailed explanation. And the next is the small diesel engine “CD20 type” installed in the FF vehicle. This is the Japan’s first V6 engine “VG30DETT type” (1983).  Looking at these, they can testify how quickly the quality of engines have improved from the stage of the imported technology to purely domestic technology, and how capacity and performance have also greatly improved in this period.     When it comes in the 1990s, racing cars Nissan E-  engines x007.JPGengines, such as the “VRH35” engine (1992) and “VRH50” (1999) which had used in the Le Mans Race, well demonstrated powerful turbo functions in running.  Regarding the engines of small vehicles, “HR12DDR type” mounted on “Nissan Note”, diesel engine “M9R type” which jointly developed with Renault, etc. have become newly introduced in this period too.

Nissan E-  engines x004.JPG   However, the highlight would be the new engine of the recent EV “Nissan Leaf”.  The detailed explanation about its performance and feature is available at the special exhibition corner too. The visitors can be convinced in the exhibition that Nissan is still standing at the forefront position of engine development in Japan, even though there exists some management stumbling in the firm,  Especially, Nissan’s efforts seem to be worth to take attention while the automobile industry is now shifting from gasoline to electricity now.

Nissan E-  illust x014.JPG   Formally, the museum was built to train the Nissan’s industrial engineers and has been collecting automobile parts and engines Nissan E-  Overview x002.JPGfor this purpose since around 1978.  But when Nissan’s Yokohama factory set up the new Guest Hall, the facility was reformed as a museum in 2003 to demonstrate Nissan’s long technology development history using the headquarter office.   It is said that the museum now preserves over 180 units of classic engines, including prototype, motor sport engines and aircraft engines.  It is precious that Nissan E-  engines x015.JPGhistorically valuable internal combustion engines are entirely gathered here. We can see there the outstanding structure and feature changes of the internal combustion engines by our own eyes, And, we can be inspired to see how EV engines are currently evolving and its related technology is advancing.Nissan E-  cars x006.JPG

In recent years, automobiles are facing radical shift of environment, like energy issues, safety measures, digitization affairs and AI advancement. Then, it is interesting to think of how the automotive engines, which are the heart of automobiles, will be changing its figures in the future.  Also, in terms of corporate history, it would be valuable to see the founding background, Nissan E-  cars x007.JPGtransformation, evolution and rise and fall of the big company like Nissan Motor in the its Yokohama factory, which is designated as a historical heritage.

The other day, I went to the “Tokyo Motor Show” held in Harumi, Tokyo. There I felt a new air blown in the automobile industry, and I was much curious about how Nissan’s future technological efforts will be going as well as the company management.  In this sense, this Nissan Engine Museum visit has given me a valuable record.

Visit historic “Gas Museum” in Kodaira, Tokyo

Showing how extensively gas energy equipment was giving impact to Japanese people’s daily life in history

Tokyo Gas- Logo x01.JPG

When the first “Street Gas Lamps” appeared in Yokohama and Tokyo in the Tokyo Gas- outlook x01.JPGearly time of Meiji, many people would have been startled and also applauded in looking at these bright lights because they had been only known some dimmed oil candles or lanterns at nighttime.  So, we can easily imagine how greatly people at that time were impressed by the new light source and how they see these glaring lamps as the “light of Tokyo Gas- G Equip x01.JPGcivilization” with feeling the new era having really arrived. Recently in the occasion I’ve heard there’s a museum to demonstrate these historic issues in Kodaira, named the “Gas Museum” which was set up by Tokyo Gas Co. in 1967. So I visited the Museum because I had some interest in the gas business as a modern energy source and its impact to the society in history. Tokyo Gas- G Lamp x06.JPG

When I visit, the museum is facilitated in two historic red brick buildings, one is for the exhibition of historical gas lamps and the other is for various old gas equipment. The former (Gas Lamp Pavilion) displays a variety of gas lamps used in the Meiji era as Tokyo Gas- Nishiki-e x02.JPGmonumental exhibits, and the latter (Living Equipment Pavilion) has various gas stoves and kitchen utilities used in the Meiji, Taisho, and Showa eras.  There, the numerous goods related to gas equipment such as gas cookware, gas heater, and industrial gas machines were orderly displayed there. Visitors can explore in the museum how lighting system has evolved, how home heating and cooking methods have been changing over the year.

Many street gas lamps used in the Meiji period can be also observed in the museum compound.

♣  Exhibition to display Retro gas lamps and Ukiyo-e pictures

Tokyo Gas- Illust x01.JPG     First, when looking look at the “Gas Lamp” exhibition, we can see many rare Tokyo Gas- G Lamp x03.JPGilluminating “Gas Lamps” that were used first in Japan in the early Meiji period.  Most of them were decorated ceiling lamps from Europe for furnishing a Western-type reception house “Rokumeikan” or other important public buildings, including “Upward arm gas lamp”, “Counterweight flexible lamp” made in UK”, “Hanagas lamp” that Tokyo Gas- G Lamp x02.JPGlooks like fireworks, “Wall-mounted glass lamp” which were used in the middle of the Meiji era.  Many lamps are still able to put on light now.  The large gas chandelier withTokyo Gas- G Lamp x01angel’s statue which had made in France in the 19th century is also available there.  Further, in this Gas Lamp Pavilion, countless commentary boards are provided for giving information how gas as a light source was invented and became used, and how introduced in Japan. So the development background of the gas lamp can be understand well. 

<Nishiki reflecting social change brought about by gas streetlight>

Tokyo Gas- Illust x05.JPG      There are also many “Nishiki-e” woodblock paintings related to gas lamps Tokyo Gas- Nishiki-e x04.JPGon display which were drawn during the Meiji period.  Looking at these paintings, we can feel how precious the gas lamps were at that time, and how the state of urban scene has changed in the Meiji era.  These exhibits are really valuable for knowing the changes in social life during that time of period.     Furthermore, in the museum Tokyo Gas- Nishiki-e x03.JPGyard, dozens of monumental “Street gas lamp” are placed that first appeared up in Yokohama, and Ginza Tokyo in the beginning of Meiji. This is regarded as the most important exhibit in the museum. In addition, valuable items of street gas lamp, such as the lamps of London and Paris in 19th century, are also exhibited in the compound.

 

♣  Living Equipment Pavilion where gas appliances are displayed

Tokyo Gas- Company x03.JPG     However, the gas lamp, which had been flourishing in the Meiji Tokyo Gas- G Equip x07.JPGperiod, gradually turned to the electric lights as a source of lighting that invented by Edison due to the durability and lower costs of electric lamps.  Under these circumstances, the gas supplying system were gradually shifted to use as heating sources.  The “Living Equipment Pavilion” clearly show us this change.  Here, we can learn how gas-fired appliances being accepted among Japanese people, and how gas appliances have made diversify our Tokyo Gas- G Equip x16.JPGsocial life, what extent the technology development has transformed our household styles. Particularly notable changes would be the evolution of appliances in the kitchen woks and the heating system in the living conditions.     And it can be seen in the exhibit Tokyo Gas- G Equip x10.JPGthat Japanese home life has revolutionary changed due to the spread of gas utilities from the period when firewood, charcoal, or ample furnaces were only available sources of heating and cooking.  The exhibition also touches on the other field of usage of gas for industry which has greatly advanced over time and contributed to the modernization of industry as well.

< Changes in kitchen and heating appliances seen in the exhibition>

Tokyo Gas- G Equip x15.JPG    First of all, we can see a valuable exhibition in the old kitchenware in the pavilion, such as a Japanese-style gas furnace “Kamado”, “gas iron” that appeared in 1902, a Columbia-type two-mount clay cooking stove “Shichirinn” (1904) imported from the UK, etc.  For the heating equipment, “open flame gas stove” Tokyo Gas- G Equip x19.JPGTokyo Gas- G Equip x12.JPG(British made 1900s), Japanese unique gas brazier “Gas Hibachi” are the rare collection.  These were very expensive ones at the time and could be affordable for wealthy class people only, but they gave a big impact to common people as well.     However, as the time passes, these gas appliances were becoming spread in the urban communities, and gradually penetrated to general household as popular daily Tokyo Gas- G Equip x18.JPGappliances. This changing situation is well reflected in a series of exhibitions categorized by year of used.  For example, quick boiling “Hayawaki gas kettle” for baths in the early Showa era, a club shaped “Kani-type stove” for home use, “Tabletop handy stove” and others are found in the exhibition.
Becoming after the high-growth era after the War, various gas refrigerators, gas automatic rice cookers, gas stoves, gas bath kettles, etc. have appeared, and they became commonly used in the Japanese Tokyo Gas- G Equip x14.JPGhousehold.  The technological evolution during this period is also remarkable. There it will be understood how the safe and stability of the heat appliance improved, the designs were upgrade, and the usage simplified. And people recognize now they become indispensable household items.      On the other hand, it was a remarkable that equipment of gas has faced severe competition with electrical products and sought the way of coexistence with them at the same time appealing its features. And now both of them become indispensable two pillar of energy resources in the society.

♣  Changing gas production methods and gas raw materials

Tokyo Gas- Illust x06.JPG     The changes in gas production and supply systems are extensively Tokyo Gas- G Equip x02.JPGintroduced in the exhibition.  Initially, energy gas had been generated mainly by steaming and burning coal. Then many factories were set up for delivering them to various locations. However, since the 1960s, the gas generation has gradually turned to the extraction method from oil refining Tokyo Gas- G Equip x03.JPGprocess, what’s called LP gas.  And by this shift, the gas supplying capacity was dramatically increased to be able to cover wider areas.
However, on the other side, the building up of huge capacity tended to invite the environment problems Tokyo Gas- G Equip x04.JPGbecause the smokes and residues from factories were causing serious land contamination and air pollution.    Anyway, the expanded gas supplying system has popularized the gas equipment and improved a lot household work in the urban areas. That also bring a great benefit for residential in rural areas or people in remote areas as well. The appeared new gas service was a propane gas delivery in the container forms, and it greatly promoted to spread the gas equipment and beneficiated family life Tokyo Gas- G Equip x20.JPGthroughout Japan, particularly rural area.
Furthermore, since the latter half of the 1970s, with the advancement of marine technology and cooling facility, liquefied natural gas LNG has been born by being directly imported form the overseas resource site. Today most gas supplies are shifting to LNG. That led the dramatic increase supply capacity of gas too. It eventually contributed a lot to improve the efficiency as industrial energy sources, electric generation, and daily life purposes as well.     These processes are explained well in detail in the “Living Equipment Pavilion”. It is interesting to look into the technological evolution of thermal energy sources and changes in daily heat equipment through exhibits

♣  Establishment of Tokyo Gas and significance of the business

Tokyo Gas- person x01.JPGTokyo Gas- person x02.JPG      The first gas lamp installation in Japan was started in 1872 by a businessman named Takashima Kaemon in Yokohama. (Takashima is also known as a founder of Tokyo Gas- Company x02.JPG“Takashima fortune teller).  Then, street gas lamps were lit in Ginza too in 1874 and Tokyo City Gas Bureau was designated to handle them (1976), and later, the private company “Tokyo Gas Company” was born by transfer the business in 1985. The company itself was actually by Eiichi Shibusawa and Soichiro Asano who recognized the gas installation as an important social Tokyo Gas- G Lamp x07infrastructure for the social civilization and industrial modernization in Meiji.  In the beginning, the prime business was to build the gas supply network for the street lamp in major cities, which was mainly architect by an English engineer named Henri Brelan from England. He planned to build a factory in Kanesaigi-bashi, Tokyo, and delivered the Tokyo Gas- G Equip x21.JPGgas to light the street gas lamps in Kyobashi and Ginza area.    The company’s lighting business had been technically the “open flame gas lamps”. But soon later, with the “Incandescent gas mantle” technology (invented in 1886 by R. W. Bunsen) the illuminating power of gas lamp was greatly multiplied and the demand for gas lighting equipment was increased greatly. One of the companies that produced this mantle was Tokyo Gas Electric Industry (TGE), which later became Hino Motors.

<To expand and contract gas production plants>

Tokyo Gas- Company x01.JPG   Tokyo Gas Co. has enforced its business by merging other gas-related companies such as Chiyoda Gas in the process. Then, Tokyo Gas Co. initially vigorously set up gas factories in various locations such as Senju, Fukagawa, Kawasaki, Toyosu, and Tsurumi in order to supply resource gas to Tokyo Metropolitan area by using these factory networks. At first, the gas was produced mostly by the coal combustion methods.  However, as I mentioned before, Tokyo Gas- Company x04.JPGthese factories were beginning to be closed because the material was replacing to the petroleum and liquefied natural gas (LNG) since around 1970s.  The Gas Museum itself is a building that had been used for factories or offices during the Meiji Taisho period.  As a matter of fact, “Gas Lamp Pavilion” is a historical red brick building at the Tokyo Gas Hongo branch office (built in 1909) and “Living Equipment Pavilion” that existed at Senju factory (built in 1912).

 <The Tokyo Gas Factory site that turned to a fresh market>

Tokyo Gas- Logo x02.JPG      Around these conditions, the “Tokyo Gas Toyosu factory”, one of the Tokyo Gas- Company x05.JPGmain factories, was closed in 1997.  So the site had been handed over to Tokyo Government under the Tokyo Bay Waterfront Project (Sub-Tokyo Subcenter Development Plan) and designated as the relocation candidate of the former “Tsukiji Fresh Market” in Tokyo. And the site of the factory has finally transformed to the “Toyosu Fresh Market” (2019).  However, as Tokyo Gas had been operating the coal combustion Tokyo Gas- Company x06.JPGmethod for a long time, it was revealed that the residues or by-products of factory caused serious pollution.  It’s now settled, but the construction plan of Toyosu Market was exposed to criticism as serious political problems for one time.       Today, this vast site of Toyosu changed to a new urban landscape filled with office buildings, commercial facilities, and green area. And there lacates a science museum called “What’s the gas museum” symbolically built by TG for advertising the usefulness of gas energy utilities.

After the visit

Tokyo Gas- Illust x09.JPG     With looking the exhibition of the museum, I felt I could understand a bit how the gas business was spread as a part of Japan’s social infrastructure, how it changed social life, and contributed to the industrial development in terms of energy source since the Meiji era. Tokyo Gas- outlook x04.JPG In particular, I was impressed much with the development of gas appliances, advancement in technology of the way for using heat sources, and changes in living and living environments. That was reflected well in the exhibits.  In addition, the competition and complementary relationship of gas and electricity business, changes in raw materials from coal to oil and shifting liquefied natural gas, as well as the evolution of industrial forms by using gas and electricity, were very interesting subjects.  The only thing I’ve Tokyo Gas- Nishiki-e x01.JPGcared a little is that there are few references to environmental problems brought by the gas business in the process.      In any case, it seems precious that historical red brick building is used for exhibition as it was, and the memorial exhibits are conveying the scenes of changing social and family life since the Meiji Era which had brought about by the supply of gases.

Visit Isuzu Automobile Museum Isuzu Plaza

–Shows  remarkable description of Isuzu’s historic evolution and technology development– 

IsuzuP- logo x03.JPGLast month, I went to Motors Museum “Hino Plaza” last , then IsuzuP- Entrance x01.JPGnow I decided to visit Isuzu Motors in Fujisawa city, Kanagawa  this time, since I’v heard there’s  unique facility called “ISUZU Plaza” exhibiting historical auto products that was  opened just two years ago in 2017.  The Plaza is functioning well as a automobile museum in explaining IsuzuP- Exhibit hall x03.JPGthe history of automobile and the related technology.  That is displaying the most Isuzu’s vehicles they have produced since its beginning, including Isuzu’s latest brand trucks and buses, in addition to the history IsuzuP- Entrance x05.JPGof Isuzu Motors itself, as well as its engines of Isuzu. The museum also exhibit its assembly processes of working vehicles and technology background. I’ve got impression that is a quite useful  museum to examine the development of Japanese working commercial vehicle industry alongside with Hino’s Plaza..

ISUZU PLAZA HP: https://www.isuzu.co.jp/plaza/

<Exhibition of Isuzu Plaza>

IsuzuP- logo x01.JPG  The exhibition of “Isuzu Plaza” begins with briefing of Isuzu’s historyIsuzuP- History x02.JPG first, and, introducing successive engines developed by Isuzu, and then it proceeds to the exhibition of various models of bus & truck including the Isuzu’s latest heavy trucks and special vehicles. In addition, there’s an explanation of the structure and mechanism of IsuzuP- Exhibit hall x02the truck and find the systematic illustration of the production process are displayed too. There many miniature models of various truck and bus is exhibited to show how the company has been involved in the various commercial vehicles. Finally, the plaza offers future image of Isuzu products and global strategy.    The distinctive feature of this museum would be the exhibits that various classic historic vehicles have been nicely preserved and displayed them in the state being able to move.   IsuzuP- Truck x03.JPGAnother attractive point is the installation of large, moving diorama that replicates how trucks and buses play an active role in modern urban society.       Below, I’d like look into the history and development of Isuzu along with the flow of the exhibition, and summarize the history and technology of Isuzu development, recent efforts, characteristics of the museum as seen in the museum plaza.

♣  The history and development of Isuzu Motors found in the exhibition

IsuzuP- History x05.JPG     Isuzu Motors was believed to be founded in 1916. However, the IsuzuP- History x01.JPGorigins of the company can go back to the Yokosuka Shipyard, which was established by the Edo Shogunate and transferred to the Meiji government. In the Meiji era, this shipyard was purchased by Tomoji Hirano, and he established Ishikawajima Shipyard (current IHI), and then that was led to move to the actual born of current Isuzu Motor now.  This Ishikawa began to initiate the move of automobiles production in anticipation of big future business. IsuzuP- Entrance x04.JPGThis year is 1916, so it was regarded as the founding year of Isuzu Motors.     Meantime, the company established an “Automobile Department” and made it independent later as named Ishikawajima Auto Works.  Under this circumstance, the company started the first production of car in 1929 in partnership with Wolseley UK. This is the “Wolseley A4 car”.        And then, the Ishikawajiama merged with “DAT Automobile Manufacturing (later transformed to Nissan) to strengthen the production later, and the name of the IsuzuP- Bus x01.JPGcompany itself changed to the “Automobile Industry Ltd.” (1933) at that time. This transforming is a bit complicated, but it is extensively described as Isuzu’s company history in the lobby of the building.  By the way, the actual product of the first “Wolseley A4 domestic car” is displayed in the main lobby as a monumental exhibit of the Isuzu Plaza.  Besides, around this period, “Sumida M-type Bus” (1929?) was also produced. This restored car is also displayed in the hall.  So you might imagine the situation of automobile in Japan at that time of period.

IsuzuP- History x04.JPG   On the other hand, Isuzu was producing domestic trucks TX40 truck in 1938 with its own initiative.  Actually, it said that, prior to this production, the company had already begun to cultivate a diesel engine technology and tried to use it for truck IsuzuP- Truck x07.JPGmanufacturing.  In this way, Isuzu became a pioneer of diesel automobiles in Japan and change the name to the “Diesel Automobile Industry” in 1941. Then it started to produce various automobiles under these schemes. During War time from 1942, Isuzu was vigorously engaged in producing armored vehicles with request of Japan’s war-IsuzuP- logo x05.JPGtime government and a lot of automobiles and trucks were produced by its hand. However, just after the War vast devastation of Japan by War, the most facilities were devastated. So, the real development as an automaker of Isuzu had to wait for several years. But the recovering process was quite fast and dynamic promoted by huge demand of commercial vehicles for public transportation after the rapid economic growth of post-War Japan.

♣   Post-war Isuzu car production model and historic exhibition

IsuzuP- Illust x05.JPG    After the War, responding to big social demand of commercial vehicles, the company changed the name to “Isuzu Motors” to show intention to involving in the production of trucks and buses with using IsuzuP- Truck x08.JPGdiesel technology, particularly in the field of heavy-weight vehicles. The other technology challenge was to produce tough vehicles to endure severe natural conditions, like fire-fighter’s work, natural disaster rescue operation, and exploration works to the Antarctic. In the exhibition hall, this kind of challenging works are displayed with real operation vehicles.

IsuzuP- Illust x08.JPG Post-war Isuzu had also involved in the IsuzuP- Car x02.JPGpassenger car as well. The high-end passenger car “Isuzu Bellel” was well reputed by the Post war autoloving generations.     However, after that, in the 1980s, production of passenger cars was stopped and afterward Isuzu has been specializing in the production of trucks and IsuzuP- Bus x02.JPGbuses only.  The most vehicles produced under these periods are extensively displayed at the history corner in the hall.  They are quite helpful to understand the company’s business trend in this period.

 

IsuzuP- Illust x01.JPG      First, in the truck category, the Isuzu TX80 truck (since 1946), the ELF series (since 1959-), the Forward series (since 1970-), and IsuzuP- Truck x05.JPGthe large truck series GIGA (since 1987-) were continuously developed. These are consecutively upgraded technology and design-wise up to the current latest models.  In the bus production field, the “BX91 bus” was produced as early as 1948, the “GALA” series bus was developed IsuzuP- Bus x03.JPGin 1996, and the” ELGA” series bus was also developed in 2000.    You can see some of these actual vehicles, and miniature models of all successive vehicles which are displayed with the chronology at the wall board. Then you can understand how their technology has been evolving from simple trucks and buses to more advanced and larger scale vehicles, or to more sophisticated ones. Many small and medium-sized vehicles have been also followed this line of development.

♣   Development of Isuzu diesel engine and features of truck production

IsuzuP- Engine x02.JPG     Isuzu has an advantage in diesel engine development from the beginning and has been developing their business by using IsuzuP- Engine x01.JPGits technology in trucks, buses and passenger cars.  Therefore, many real engines of Isuzu are proudly displayed with their technical background.  For example, there are “H-series” engines installed on medium-sized trucks like “ELFs”, “P-series” engines used in large trucks since the 1970s, and “T-series” engines since the IsuzuP- process x05.JPG1990s.  The engine’s ability is posted along with each utilized vehicle. You will be able to confirm the characteristics and performance of the engine developed by Isuzu.

 

♣   Mechanical structure of trucks shown in the exhibition and its manufacturing process

IsuzuP- process x04.JPG   One of the features of the museum is that the manufacturing process of Isuzu trucks is explained in detail with flowcharts and actual components.IsuzuP- process x01.JPG  In fact, if you walk along the flow chart corner, you can visually check the design concept, manufacturing process, and functions and features of commercial vehicles that are clearly different from passenger cars.  In addition, the side cut models of the completed medium truck are on display there too, so you IsuzuP- process x03.JPGcan examine the internal structure of it.  In the manufacturing process, the miniature models of real factory are provided as well so that you can observe the full process from parts making to vehicle assembly, inspection, and shipment flow with your own eyes.  I thought this was a unique feature of this museum.

♣   The features of the museum and the charm of the diorama exhibition

IsuzuP- Exhibit hall x04.JPG      One of the attractive points of this museum is a moving diorama exhibiting demonstrative shows using the largest space in Japan.  There is the scene simulating actual modern urban transportation, and on the diorama, you can see the variety of miniature cars moving automatically. You can get real images how trucks, buses, fire engines, delivery vehicles which support public logistics and people’s move with IsuzuP- Diorama x01.JPGchanging forms from morning, to noon and until mid-night. It is really spectacle to be able to look the situation where it illuminates many lights with sounds of urban bustling.  You might be fascinated by the dynamism and beauty of the diorama there. When I visited, a group of Thai trainees cheered and watched enthusiastically. I’ve felt there’s a new style of technical museum that emphasis much on the entertaining elements not only technical and operational explanation.

Remarks

IsuzuP- Illust x0.JPG      This time, I was able to see the concept of commercial vehicle’s technology, its development process and mechanical structure which are different from passenger cars by visiting the Isuzu Motor’s museum Plaza following Hino’s similar facility. IsuzuP- Entrance x02.JPGI can realize that   firstly, significance of truck technology which should run with heavily loaded stuff, while seeking its extreme safety, resilience, and efficiency. In addition, passenger buses must follow the standard of absolute safety, comfort, and durability. I also understand how these vehicles are extremely required high level IsuzuP- Bus x04.JPGof technology to bear heavy responsibility to the society and to operate smoothly in the modern society.  Both the museums of Hino and Isuzu seem to be functioning well in explaining the history of automobile and the related technology well while emphasizing promotion of products and companies themselves in good balance.

Visit Truck and Bus Museum of Hino Auto Plaza

-Explore to the Hino’s commercial vehicles and their technology

Hino Auto- logo x01.JPG      Hino Motors, along with Isuzu Motors, is one of the leading Hino Auto- overview x01.JPGcommercial vehicle manufacturers in Japan. And it now holds a large market share in the truck and bus sector in the world.  This Hino has opened the Hino Auto Plaza (Kodaira City, Tokyo) in Hino Auto- overview x02.JPG1997 as a specialized museum for exhibition of trucks and buses. I visited there in August with having some concern. The museum tries to show the company’s business and technology development in the exhibition with looking back the Hino’s 100-year history which has producing various historic trucks and buses.

<Outline of Exhibition>

Hino Auto- illudt x05.JPG     There the variety exhibits of Hino’s vehicles of Hino are available, Hino Auto- truck x05like renowned memorial trucks, buses, and passenger cars, in the real figures of automobile and scale models, in which the company’s business development and foundation of technology are reflected. Especially the corridor’s exhibition in the main hall is outstanding. Particular interest is rare exhibit of Japan’s first truck “TGE-A” (1917), in addition to the domestically developed aircraft model, bonnet-type buses, passenger Hino Auto- overview x04.JPGcar Contessa, tricycle “Hustler”, and Dakar Rally winning vehicles. These are evidence how Hino was actively involved in producing various automobiles and developed their technology. In the special corner, even Hino’s aircraft engines in the early 1930s are displayed.   It seemed to be a precious museum to know the development of the Japanese automobile industry, particularly in the field of commercial vehicles.

♣  The early days of Hino Motors seen in the exhibition

Hino Auto- person x02     During this visit, I can noticed for the first time that Hino Motors had been initially engaging in the simple ignition device of the “Gas lamp” that had first appeared as a symbol of the civilization in the early Meiji period. Hino Auto- truck x06.JPGThe founder was Matsukata Goro, a fifth son of Matsukata Masayoshi, a famous politician in the Meiji period. who .The company had transformed later and set up “Tokyo Gas Electric Industry (TGE)” in 1910 as the first mechanical manufacturing company. While doing so, in 1918, the Japan’s military agency in Meiji offered the company to develop a military truck vehicle, named “TGE-A”, then Hino had utilized this opportunity and its automobile business started. At the company Hino Auto- truck x07.JPGhistory room in the museum, this foundation story is clearly explained and the reproduction model of this TGE truck are proudly on display at the entrance hall.  Meanwhile, the company TGE increased its production capacity in the military truck sector while continuously expanding its gas businesses and electric appliances. But, In the 1930s, the Hino Auto- truck x08.JPGautomobile division became independent from TGE, and later, it merged with other automobile companies in 1941 and named “Diesel Automobile Industry” during war time.  So and so afterwar, the company name was changed to “Hino Heavy Industries” (1942), and it finally became the current “Hino Motor Industry” in 1946 after the World War II.

Hino Auto- person x01.JPGThe whole period from the TGE to Hino Heavy Industries, Hino’s technology was said to be consistently led by a mechanical engineer Hino Auto- history x04.JPG“Isamu Hoshiko”, who was known as an excellent expert of automobile engineering at the time. His contribution to Hino was honorably displayed in the company history room.     The development of vehicles, technologies, and businesses in the early times of year is depicted in the chronology charts at the corridor of main exhibition hall with various Hino Auto- history x02commentaries photos.  What is unusual is that a numerous miniature car models provided by Tomica Co. are observable in the exhibition floor (called Tomika Town exhibition). It is really amazing and enjoyable to be able to see the whole Hino’s vehicles in full sets of models.

(Note: Describe “Hino” stands for the various former name of the companies, including  Hino Motors ’, “ Tokyo Gas Electric Industry ”and“ Diesel Automobile Industry and others here)

♣  Shift from military vehicles to commercial cars as seen in the exhibition

Hino Auto- illudt x03.JPG       Hino’s automobile production was predominantly centered in military use vehicles in the early period, but some involvement was shown Hino Auto- bus x03.JPGin the non-military commercial sectors in this time too. Of these, it is said that the TGE-MP bus (known as the “Chiyoda Bus”) was manufactured in 1930. Some multi-purpose-trucks and trailer cars were also produced by Hino.      However, it was not until the 1950s that Hino began Hino Auto- truck x09.JPGto be involved in the full-scale production of commercial vehicle, especially initiatives in the trucks and buses for business purposes began this time.  First, in 1946, Hino has produced T10 transport trucks using discarded scrap parts from war time vehicles.  After that, the bonnet type of trucks, TH Hino Auto- truck x10.JPGtruck (1950) which modified former TE truck, and the several flocks of TE20 transport truck was consecutively put into market in the short time period. It can safely say that these manufacturing strategy and posture have really laid the Hino’s solid business foundation today. So, the successor vehicle E11 is displayed in the outdoor hall as a commemorative exhibit.

♣   Challenges to the airplane engines in the exhibition

Hino Auto- illudt x09.JPG     Hino’s prewar automobile manufacturing was strongly associated with the support and order from the Japan Army.  Military vehicles suchHino Auto- engine x05.JPG as the previous TGE type truck, RGE high-rail tow truck, and armored tow truck had been the main production fields, but they were also deeply involved in the development of aircraft engines at the request of the military.  A number of airplane engines, such as the first domestic aircraft engine “Kamikaze” in 1928, “Tenfu” (1930), “Hikari Three” (1936), and “Hatsukaze” (1942) had been developed in technological challenges. It is said Hino Auto- engine x06.JPGthat these were all actively used in the Pacific War as air fighter engines. The actual aircraft engines are on display at the Aero Engine corner in the building. There you can clearly observe the technical challenges of Hino at that time.
These real engines had never been opened in public because they were all confiscated by the Occupation Forces and the Hino Auto- engine x01.JPGdomestic development of aero engines were long prohibited after the War for certain of period.  In this meaning these exhibits are quite precious ones.  A scale model of the 1938’s aircraft “Kokenki” was exhibited too hanging from the ceiling of atrium gallery. This is also a quite interesting exhibit object.

♣   Legendary passenger cars of Hino that’s showing its new tech challenges

Hino Auto- logo x03.JPG      Hino has also entered the passenger car sector, especially the minicar Hino Auto- P car x01.JPGsector after the War.  In the meantime, the company has produced several renowned cars to the automobile world from 1950 to 1960s. Passenger cars produced during this time are proudly displayed in the exhibition hall. They are Hino Renault 4CV (1953), Condessa 900 (1961), 1300 Coupe (1965), etc.  A lightweight tricycle “Hustler” which had Hino Auto- P car x03.JPGHino Auto- P car x02.JPGexported to Southeast Asia in 1960s is also exhibited in the hall.
However, Hino has stopped production of own passenger cars since forming business alliance with Toyota in 1970s, and afterward the company became concentrating and specializing on production in the truck and bus sectors.

♣  Development of post-war truck business and bus business

Hino Auto- truck x02.JPG     Hino’s truck and bus business has expanded rapidly since the 1960s, and its technological advancement and production have significantly proceeded further. First, in the truck sector, Hino Auto- truck x01.JPGstarting with the TE type (1959) mentioned above, the KM300 type (1966), the KG300 type heavy truck (1967), the KL300 type medium truck (1969), the high cap HE type trailer (1971), FD172 rangers (1980) etc. were put on the market one after another.  That time was precisely a period of high economic growth after the War in Japan, so it can rightly say that Hino’s transport vehicles have Hino Auto- engine x02.JPGgreatly contributed to the Japan’s economy through providing essential means to the logistic world. The high-power, high-efficiency, high-durability engines are particularly important for transport trucks. So, Hino has accomplished significant Hino Auto- truck x03technological leverage in this aspect.  In the hall, these series of engines developed by Hino are displayed in row order.
In addition, for demonstration of this technical capability, the actual vehicle of the “Japan Ranger” (1996) that won the Dakar Rally is on display outdoors too. It is worth to look these memorial objects.

<Expanding public bus business>

Hino Auto- illudt x07.JPG       Hino made a big leap in the bus manufacturing field as well. First, Hino Auto- bus x04.JPGthe bonnet bus BH10 was produced in 1950. It is said that the bus was loved much by urban people as a small convenient public vehicle. This real bus is displayed in the hall along with the specified engine for it.  After this bus, a number of public buses were developed earnestly in consideration of ride comfort Hino Auto- bus x01.JPGand design, such as the floor engine monocoque BN bus, the skeleton-structured RS bus (1977), and the Hino sightseeing bus “Seleca” (1992), which was famous as a sightseeing bus. You can check these models at the minicar corner in the building.


♣  
Recent Hino’s commercial vehicle and new engine initiatives and results

Hino Auto- logo x04.JPG       In recent years, Hino has been going to take new initiatives Hino Auto- New car x01.JPGfor producing special vehicles, trucks, buses, etc., applying its technological capabilities accumulated previously.  In particular, during the 1990s and 2000s, the company seems to be burnishing its specialties in technology on the commercial vehicles while public concerns are growing in environment and safety issues more than before, in addition requirement to driving comport and designing Hino Auto- New car x02.JPGimprovement.  Hino seems to look its goal to become a global first class manufacturer by improving its technological capacity more than before with seeking efficient and powerful engines, fancy body styles, and enough durability.

First, in this line, Hino launched the “Hybrid Bus HIMR” in 1994 and produced the efficient small Hino Auto- truck x04.JPGtruck “Hino Ditro” in 2003. The actual HIMR bus is displayed at the outdoor venue, and the actual hybrid N04C engine is displayed inside the exhibition hall.   And it is interesting to see a platform of EV commercial environment friendly vehicle which is currently developing, and a model car of the electric car community bus “Poncho Mini” on display in the hall. You can detect there the future direction of Hino’s technical challenges in the exhibition.

Remarks after visit

Hino Auto- logo x02.JPG       In the exhibition, we can see the active features of Hino Motors that has consistently focused on its technology development on Hino Auto- truck x05transport trucks, buses and other commercial vehicles, and finally gained current reputation as a global manufacturer in this field.  However, I could have dearly notice that the company was just born as a tiny mechanic manufacturer in the early Meiji period, but it had gradually expanded its business by involving  in various military vehicles, Hino Auto- overview x03.JPGengines, aircraft production , while receiving strong government supports. It seemed to be a long process with courageous challenges to seek technology achievement. The accumulation of technology nurtured in this process was surely applied in the production of commercial vehicles like trucks and buses, where it is strongly required the heavy engine load, as well as long time ride comfort, driving safety. it would be an Hino Auto- engine x07interesting issue how Hino will tackle the current social demand for development of electric cars and automatic driving technology in the midst the automobile technology trends are shifting from internal combustion to the other energy options. It was enjoyable and enlightened museum to see the automobile development world.

Visit the Nature and Science Museum of Tuat, Tokyo

— Museum is showing amazing collection of silk and textile products in history

Tuat M- logo x1.JPG  I happen to have a good chance to visit the Nature and Science Museum (Tokyo Tuat M- Outlook x1.JPGUniversity of Agriculture and Technology, Tuat) in Koganei city, Tokyo in the early August. The Museum  is very proud of long history being able to back to 1880s  as it had started as a Silkworm Testing Institute under Meiji government.  And afterward the facility was transformed to the present Museum in 1997 under the university of Tuat which was founded as the Agricultural Academy in Meiji Tuat M- Outlook x3period.   Under this background, the Museum has been ardently worked on collecting  historical textile objects long time since the Meiji period, and tried to exhibit them to the public, including weaving machines, sericulture facilities, worm seed samples, various textile equipment, and now added a number of exhibits related to the recent chemical fiber Tuat M- Silk x1.JPGtechnology products as well.  It would be an excellent facility for the people who have interested in the textile industries, particularly regarding silk industry.   The background  was the recognition that  the silk and silk products have been one of Japan’s most important export products and been playing a significant role in modernizing Japanese industry.

Nature and Science Museum (Tuat):
http://web.tuat.ac.jp/~museum/information/index.html


 ♣  Outline of the exhibition seen in the museum

Tuat M- Illust x2.JPG    The  Museum holds several exhibition rooms to display significant textile products and their machines, particularly on the silk related materials.     For the example among them, the “Textile Exhibition Room”Tuat M- Silk Worm x1.JPG and the “Measurement room” exhibits, many machines and tools related to the silk industries, including silk specimens, its tools, production machines, and measuring instruments which are especially related to cocoon growth management, silk thread generation, spinning process, silk product production and quality control, etc. All exhibits are visually indicating the development of the silk industry.
Tuat M- Silk machine x10.JPG     In “Textile Machines”, you can list the textile machines starting with traditional looms and consequently developed to machines present day.  In addition, the “Nishiki-e” corner is a fascinating exhibition that is describing a visual record of how important sericulture thread was during the Edo and Meiji periods.     Tuat M- Ukiyoe x1.JPGOn the other hand, the “Academic History Exhibition Room” and “Award Room” show how the university has been advancing its educational and research activities since the Meiji, with focusing agriculture and textile science. It is worth seeing in honor of Professor Akira Endo, who played a very important role in medical science. The museum also Tuat M- Illust x11displays functional robots in the museum lobby in order to show its modern engineering activities. Here,  I’ll try to look back the history of the Japanese silk and silk industry along with the exhibits at each exhibition corner.

 

♣   Development of sericulture in the exhibition

Tuat M- Illust x5   The museum seems to try to introduce whole features of the development of Japanese sericulture industries, include silk thread and silk industries with using various specimens and samples.

<Origin and development of Japanese silk thread industry>

Tuat M- Silk Worm x3.JPG       It’s widely known that sericulture and silk producing industry had a long history.      In that process, silkworms have been deliberately fostered and produced to various type of raw silks  and yarns. It is believed that the silk technology  was introduced to Japan from ChinaTuat M- Illust x10.JPG during ancient Yayoi period in the thousand years ago.  Since then, , silk products had long been appreciated as high-quality textiles among for celebrities in Japan, but in the Edo period, they became quite popular clothes and traded well among Edo city’s population.  For this reason, the sericulture and silk industry were strongly promoted and became produced in various places.  In particular, after the Meiji era, silk thread exports were upgraded to the  powerful means to earn foreign Tuat M- Outlook x11.JPGcurrency. As a result, they have grown as one of the Japan’s core industries aftermath.  In addition, the technology associating with silk industries was marked significant advancement since the government had vigorously established many silk research and testing center. These situation at that time can be observed that in the exhibition, like the improvement of cocoon quality, the nurturing of silkworm, the improvement of the quality of yarn, the efficiency of spinning, etc.

<Technological development of sericulture>

Tuat M- Silk Worm x2.JPG       The museum explains technical changes in the sericulture and its works at the former period in detail.  When it comes to the sericulture process, first, the hatched silkworms are moved to the silkworm-baskets “Sanza” and given mulberry leaves to feed for starting Tuat M- Silk Worm x4.JPGbreeding process, called “Hakitate“.  The matured worms are then transferred to the tools “Mabushi” being made of rice straw and led them generate silk cocoons.  In the exhibition, various “Sanza” and “Mabushi ” samples are exhibited. Especially, special instruments such as “Rotating Mabushi” are Tuat M- Silk Worm x5.JPGdisplayed there. It is showing how the technological advances were embodied in the equipment since the Meiji Era. There found many rare goods too, Tuat M- Silk Worm x6.JPGsuch as the structural models of silkworm and sample of pathogenic objects, and so on to show the scientific analysis on the silk industries.
After all, this exhibition shows how greatly the people were making point of developing sericulture technology at that time.

<Technology process from silkworm to silk thread>

Tuat M- Silk machine x1.JPG     After generation of cocoon, the spinning process will start to convert it to silk thread (raw silk yarn). It is widely known that a major technological change in “threading” has occurred in the tools and machinery during the Meiji to Showa era. This Tuat M- Silk machine x5.JPGevolution can be observed in the exhibition. In other words, the exhibits is showing technical advancement on the equipment, such as go forward from the traditional “spinning” tools, to “reeling machines (Suwa type)”, then “multi-spinning reels”, and “automatic reeling machine”, etc.
In this development, we can see the diffusion of silk producing technology among general people in Tuat M- Ukiyoe x3.JPGthe scene, exemplified by the activities of “Tomioka Silk Mill”, one of the Japan’s World Industrial Heritage site) which was given a great influence to silk industrial development of Japan.
In addition, the museum tries to highlight the technological shift from the traditional ways to the modern ones through showing Tuat M- Silk x2.JPGthe real sample and models of silk, such as various pattern of silkworm specimens, graded specimens, trademarks of silk products, and measuring instruments formerly used, and describing how silk thread and silk production was technologically managed at that time. (You can check the details in the photos and their commentary)

<From raw silk to silk fabric>

Tuat M- Illust x4.JPG       In the meantime, the process of weaving silk thread has significantly advanced since the Meiji period. (This was already touched in the description of previous “Toyota Industrial Memorial Museum -Textile Hall”.)  These Tuat M- Outlook x6.JPGprocesses could be defined well in the exhibition of the Tuat’s Museum.  The museum has an extensive collection of ancient reeling tools across the world, traditional Japanese reeling tools, many types of looms, etc.  The display of the unique “knit” tool equipment is also an interesting exhibition.  These tools have been still operated by the museum staff, and the actual technology changes can be traced through the moving machines.

 

♣     Development of Japanese Sericulture and silk industry in Nishiki-e picture

Tuat M- Silk Worm x8.JPG      As you have seen earlier, silk production had been carried out since the Tuat M- Ukiyoe x2.JPGancient days, but it became more popular since the Edo period, and after the Meiji it has upgraded to a  prime industry thanks to the government promotion measures, named “Shokusan-kougyo industry” policy. You can see a lot of them at the “Nishiki-e Painting Room” in the museum.  At the room, there can find many features of the engagement of Edo people working on the Tuat M- Ukiyoe x4.JPGsericulture, and various textbooks and specimens subjected to the sericulture techniques.  Also, several “Nishiki-e” pictures are depicting the promotion policy of sericulture and situation of silk production in the early Meiji period. One of the interesting items would be the exhibition of Tuat M- Silk x4.JPG“Trademarks” symbolizing the status of silk merchandise transactions.
These are all valuable exhibits that are indicating the depth of concerns and spread of public interest in the sericulture and silk industries of each period.  Furthermore, the exhibition shows special relationship between the silk industry and the imperial family, like seen in the memorial pictures and treasures.

♣   Approach to modern textile science in the exhibition

Tuat M- Illust x14.JPG      The museum’s collection is mainly focusing on the silk and silk Tuat M- Silk New x2.JPGproducts, but there are many other objects in association with the textile industries.  For example, there are various exhibits related to the chemical fibers such as rayon and nylon and other recent advanced fiber materials, such as carbon fibers. And several examples, like fiber’s chemical Tuat M- Silk New x1.JPGapplications to the medical field are also exhibited there. The old and new sewing machines is also interesting exhibition too. The other exhibition room like “Awarding Room” introduces the great contribution of Prof. Akira Endo to the field of biochemistry who invented the material “Statins” controlling cholesterol.

 

After visit

Tuat M- logo x5.JPG     This visit to the Science and Technology Museum was a memorable experience to be able to learn on the history of sericulture and the depth Tuat M- Silk machine x4.JPGof the textile industry.  I could have obtain some knowledge on what’s all about of sericulture and silk industry, how precious industry in Japan, what technical features it had, and what evolution has achieved in the process of modernizing the Meiji industry. I’m really amazed the abundance of collections and exhibitions on the silk industries when walking around the museum, and actually felt the Tuat M- Silk machine x2.JPGmuseum’s outstanding contribution of historical analysis on the textile industry in Japan.
Furthermore, I got a fresh impression too about the museum’s effort to try to open broadly the social community by organizing public lectures, science classes, and publishing and other activities as new museum attempts.

Visit the “Industrial Technology Museum” of Nippon Institute of Technology

Explore the roots of machine industries in Japan as seen in the Museum collection

Museum NIT- Logo x01.JPG      Last month I visited the “Industrial Technology Museum” in SaitamaMuseum NIT- Overview x05.JPG prefecture in the Nippon Institute of Technology which is widely known for its practical and advanced engineering education. In the museum, a variety of machine tools and historical machinery since the Meiji Period are preserved and exhibited that had been greatly contributing to the development of Japanese mechanical industry. And in Museum NIT- Overview x03.JPGaddition, it displays the latest industrial machinery such as advanced NC equipment, engines, energy-saving and gas turbines too. It is also interesting that the figures of old town machining factory in Meiji is reproduced to able to see the real situation of basic machine industry in Japan at that time as a foundation. I felt that it’s a prominent facility to able to learn the history of mechanical industrial development history. Among the whole collection, more than 270 items of preserved machines and facilities were designated in 2018 for the “Mechanical Heritage” as precious industrial heritages.      The following is an expression of this visit.

♣ Aim and Outline of “Industrial Museum”

Museum NIT- Illust x01.JPG    In the museum, more than hundreds of historical machine tools sinceMuseum NIT- Overview x04.JPG the Meiji period, either imported or domestically produced, are displayed in line categorized by the year of production. Generally, machine tools are classified roughly into a sort of lathes, drilling machines, milling machines, grinding & finishing machines, process working machines, and digital machining centers. The museum’s collection covers all of these machines.is diverse. Museum NIT- Machine x03.JPG  For example, the museum preserves and exhibits a “Hand-turned lathe” (constructed by Ikegai Works) of the Meiji era, Pratt & Whitney’s “General lathe 131NCHB” in the early Showa, and a universal milling machine from Frieddeckel (Germany) , Yoshida Iron Works’ upright pole board (1950s), Ship Co. (Switzerland) “Jig boring Museum NIT- Machine x07.JPGmachine 3R type”, Multi-function machine tools, Kelney’s “Machining Center Eb type” (US , 1970s) ), Hitachi Seiko Co., Ltd. “Machining Center MBN-330” (1970s) and many other historical machine tools.   Besides these historic machines, various old looms used in the Meiji Taisho era, the 

Museum NIT- Machine x09.JPGrecent high-performance gas turbine demonstration plant (designed by a private technical research association in 1987), glass mercury rectifier (1961, Nippon Batteries Co.) are on display.  In addition, British steam locomotive “Dub 2100 Model” that had been operated during the Meiji era (1891) was also found there in a good condition.

 

♣  Utilization and production of “machine tools” starting from import as seen in the exhibition

<Background of development of machine tools in Japan>

Museum NIT- Illust x12.JPG    Japan’s industrial machinery technology now marks the world’s top class as Museum NIT- Machine x01seeing in the  industrial robot technology.  When we look into the history, however, the introduction of modern machine was the matter just started a century ago, so its was extremely difficult to master them in short time because its technology base was very poor, particularly regarding iron machines. As a matter of fact most machine tools using in the modern manufacturing firms had to be imported quite long time before the domestic production technology was finally established in the Show period, especially after the World War II.

<Infant period of Japanese Machine tools industries>

The first modern machine tools in Japan was said to be introduced around 1857 in nagasaki-zosen-wh-dock-3the end of the Edo period and the Shogunate imported them from the Netherlands. Meantime, a number of shipyards and military arsenals of Japan were rashly built to promoteMuseum NIT- Machine x34.JPG industrialization since Meiji era trying to catch up to the advanced countries. However, the Japanese modern machine technology was quite poor at that time, so their move had to completely depend on the imported machines from abroad. Museum NIT- Machine x35.JPGGood examples can observe in the Yokohama and Nagasaki Shipyard where had engaged in the repair work of ship and railway were much rely on the imported technology and machines. But, the experience of using machines had provided Japanese workers a precious Museum NIT- Machine x05.JPGchance to learn their structure and functions. Through this process, many engineers gradually mastered the technology to create this machine tools by themselves.

<Start of domestic production>

Museum NIT- Person x01.JPG        Under these learning process, a town factory of mechanic tools (currently “Ikegai Mfg Co.”) was established in Tokyo in 1889 and its owner Museum NIT- Machine x36.JPGShotaro Ikegai had successfully made two hand-turned lathes for personal use.  This is said to be the first modern machine tools domestically produced in Japan. The similar examples might be existed in various locations across Japan. But Ikegai would be a typical successful firm and their business is continuing until now as a giant machine producing company. This is a reason that the museum is proudly exhibiting this first lathe machine as memorable item to memorize its significance.

On the other hand, prior to this machine tools actually you can find there was a Meiji- Machine x04Meiji- Illust x04“planing machine” marked a chrysanthemum emblem which had been manufactured for training purposes at the Akabane Works under the Ministry of Engineering in 1872. This machine is now preserved in the “Meijimura Park” in Nagoya.  These are all precious machines that is conveying the reality of Japan’s machine industry in the. early days. Some of them are exhibited in the museum too.

Museum NIT- Person x02.JPG       After that, around the 1900s, several leading machine tool manufacturers, launched their business, such as Niigata Iron Works (1894), Okuma (1903), Karatsu Iron Works (1910), and Hitachi Seiki (1910).  But the Museum NIT- Machine x37.JPGdomestic products were mostly limited to be imitation from the Western models and the quality was not yet satisfactory to practical use as well. Then,  most of the machine tools that contributed to the Japan’s modern machinery industry had to be imported from the major manufacturers in UK, Germany, the United States for a long time even until 1950s after the War. However,

Museum NIT- Machine x05   Examples of these imported machine tools in the museum are Craven Borthers’ “Axle Lathe” (1905), Brown & Sharpe Mfg. Gleason Works “”Casa gear Museum NIT- Machine x13.JPGcutting machine ” (1910) etc. and others. Even though, as representative domestic products, the museum dared to display the Otsuki Iron Works “Turret Lathe” (1920) and the Karatsu Iron Works “Radial Drilling Machine” (1929).

Museum NIT- Logo x05.JPG    But in this process, thanks to the tireless efforts of engineers, Japan has finally Museum NIT- Machine x06.JPGsucceeded in developing adequate technology suitable for Japanese advanced manufacturing sites. That has been attained through long successive process in the development observed in history like, as the first step, import the model machines importing, then operate them and learn the mechanism and structure, begin to produce them imitating technology, and then develop own machine Museum NIT- Machine x17.JPGtechnology and apply them to the practical manufacturing. And, finally, machine producing technology in Japan could put forward to achieve the present position being paralleled with the Western advanced manufacturers. The museum has extensively tried to trace this long historical process and apply them for education and research works by the dynamic display of actual machine used in the factory.

<Reproduction of machine factories during the Meiji and Taisho periods>

Museum NIT- Illust x14.JPG  Even in this poor circumstances, several independent machine factories were Museum NIT- Machine x04.JPGactively running in town level to support the foundation of Japanese machine industries.  One of them was Uehara machine factory in Meiji period which founded by Eisuke Uehara in Mita, Tokyo in 1907. The museum exhibits the reproduction of this factory as it were in the collection. This Uehara’s factory has been manufacturing various machine parts for over sixty years until 1950s using domestic lathes made by Ikegai Iron Works. It is precious that we can see the state of the machine factory in its original form.

<Formation of domestic technology and advancement of machine tools>

Museum NIT- Illust x07.JPG      By the way, the economic conditions of World War One in the 1910s became a tailwind blow for development of Japanese machine tool Museum NIT- Machine x14.JPGmanufacturers.  The import of machine tools from the US and Europe to Japan had suddenly been ceased because of War, and this gave to a fortunate chance for rising of Japan’s domestic machine industry. For example, it prompted Ikegai Iron Works export lathes machines to the UK and Russia for the first time.  Also, since the 1930s, the machine industries were Toyota A- First stage x01beginning to show the new development. Toyota has started to engage in production of machine tools in expecting new development of automobile industry in future. Nissan was also followed suite in launching new machinery production with looking for expand of the automobile market.

Museum NIT- Machine x10.JPG   However, the real popularization of full-scale machine tools production in Japan had to wait until the period of high growth after the War since 1960s.  In the post-World War II, the rapid economic and industrial development had started. And it caused the huge demand to the advanced machine tools and strongly stimulated production of domestic machines.  Correspondingly, the domestic machine tool manufacturers, that were still technically in-matured, tried to develop their technology in the measure of focusing on technology Museum NIT- Machine x16.JPGpartnership with leading European and American companies.  As a result, the technical level of Japan’s domestic machine tools has improved dramatically to the level of world standard. Among them, the significance would Museum NIT- Machine x24.JPGbe found in the exert development of electrical discharge machines and the aggressive introduction of NC equipment for domestic machine tools. In particular, the introduction of NC is said to have dramatically improved Japan’s competitiveness in the machinery industries.

<Development of NC machines>

Museum NIT- Machine x18.JPG     The museum displays a variety of imported machine tools and machines produced by domestic manufacturers in the exhibition. For example, Kearney & Trecker’s “Machining Center EB” (1970), Lees-Branner’s “6-axis bobo HD-40”, Matsuura Museum NIT- Machine x12Machine’s “Program Control Milling Machine S-2” (1962), Ikegai’s “Numerically Controlled Lathe LX” -20N “(1978), Hitachi Machining’s” Machining Center MBN-330 “. It would be the best collection to inspect the development of Japanese machine tools.

 

♣  Recent progress in machine technology and sophistication of machine tools

Museum NIT- Illust x11.JPG       Japan’s machine tool manufacturing technology have achieved and surpassed the world standard in the 1970s. And Japan’s manufactures have Museum NIT- Machine x20.JPGoverwhelmed the United States and became the world’s greatest producer in machine tools in the 1980s.  The greatest contribution to it has been the development of advanced NC equipment and technological progress. These greatly accelerated the development of Japanese automobiles, electrical and electronic equipment, and various machine industries in the 1970s and 1980s.

Museum NIT- Person x04.JPG    Also, since the 1990s, the industrial robot technology was emerged particularly in the sophisticated manufacturing industries and led to promote of production of industrial robots in various Museum NIT- Machine x32.JPGpurposes.  Among them, you can count several advanced companies have grown fast, such as FANUC, Yaskawa Electric, and Amada, and they account for now a large share of the world.  Today, these industrial robots are widely used in automobile assembly and painting, and for also electronic parts production sites.  On the other hand, Yamazaki Mazak, Mori Seiki, Okuma and other Museum NIT- Person x03.JPGmakers are playing an active role in the machine tool production, especially NC related equipment too.  However, unfortunately these recent mother machines and industrial robots were not seen much because the Museum NIT- Machine x31.JPGmuseum seemingly try to focus on historical exhibits whatsoever.   On the other hand, the collection of other industrial equipment are quite outstanding, such as actual models of high-efficiency gas turbines in Museum NIT- Machine x28.JPG1980s, hydrogen engines, new rotary engines, are broadly exhibited in the museum. These seem to show us significance of Japanese recent technological trends in the machinery industries.

 (The description relies heavily on the Museum of Industrial Technology Collection Exhibit Guide and the  marked picture is quoted from Guide book too)

After the museum visit

Museum NIT- Logo x04.JPG      The Museum of Industrial Technology was established as one of the commemorative projects for the 80th anniversary of the Nippon Institute of Museum NIT- Machine x25.JPGTechnology. This was aimed to prompt practical education and research work for students, but it also purposes to promote science and technology in the machinery industries among general people. I was just amazed how it was possible to collect that many historic machines systematically in the museum.
In addition, the uniqueness is that many of them are preserved in the condition of operational condition, so we can actually check the functions by moving them. I felt that this museum is a really valuable facility for Museum NIT- Machine x33.JPGverifying the historical fact how machine tools have been used and contributed to industrial development in Japan. In particular, the reproduction of the town factory during the Meiji era, the first domestic lathe in Ikegai, and the exhibit of high-performance gas turbines were impressive.    In addition, although it was not possible to actually see due to time, it is attractive to see the 1890s, Museum NIT- Illust x06.JPGBritish steam locomotives that are actually running in the university.  Anyway, I felt that it was a unique museum that can synthetically link the dynamics of mechanical technology evolution and engineering education in the university.
