History

In the movie The Last Samurai, Tom Cruise is impersonating a US soldier invited to Japan at the beginning of the Meiji Restoration to teach Japanese how to build a modern army... While the movie takes some liberty with historical realities (as usual !), it was indeed a period when foreigners - from Europe and USA - were brought to Japan to help modernize the country.

Among them was Paul Brunat, who was working for a French trading company in Yokohama. At Japanese government request, he started to search a good location to build a silk mill in the Kanto area. At that time, Japan was exporting a lot of raw silk, but was lacking the technique to produce large amount of good quality silk. Paul Brunat finally selected Tomioka city for four main reasons:

- Supply of silk moths was abundant in the area
- Land was available to build a factory on a large surface
- Coal was found in quantity in near-by Takasaki city
- Tomioka had a river that could be used for the production


The silk manufacturing factory was established in 1872 (Meiji 5). It was a national government-operated factory, built under the Japanese government policy to encourage new industry. The beginnings were rather difficult, as it was especially hard to find female workers who wanted to work in the plant; indeed, since its construction, some rumors were surrounding the silk mill, including the one that the foreigners were drinking the blood of the young ladies working there. This unusual belief was not due to any vampire legend, but only to the fact that French engineers were drinking red wine they imported with them! To kill that rumor, the governor of the province sent his daughter to work there, followed by daughters of other important personalities.

When those women returned to their home after a 2 or 3-years training, they then became trainers in silk manufacture in their own prefectures, thus spreading the knowledge acquired from the French. Indeed, in 1909, Japan was the world's largest exporter of raw silk. Among those women was Wada Ei (1857-1929), daughter of samurai Sinshu Matsushiro, who wrote "Tomioka Diary" (Tomioka Nikki) in which she chronicled her life in the silk mill.

Together with the good working conditions (8 hours per day instead of the usual 12 hours, 1 rest day per week), the care taken of the employees (a small hospital was built together with the factory), the presence of those daughters of important persons quickly create an emulation, and the Tomioka silk mill became very popular. 350-500 women were operating the machines of the factory.

The French staff stayed on site the first 4 years of operation, before being discharged in 1976. It was supposed that the financial burden of hiring foreign supervisors rendered the factory not profitable. Even after the dismissal, the Tomioka silk mill continued to be always in the red, and the governement finally decided to privatize it in 1893. It continued to operate until 1987, when the factory was finally closed down. It was finally closed in 1987, when its value as a cultural and historical site started to be evaluated. In 2005, it was designated as a historical site, and in 2007, the site was registered on the UNESCO Tentative List, the step allowing a future registration as a UNESCO World Heritage site.






Visit

You can either visit the premises by yourself, or take a free tour starting every hour (see above); this tour in only in Japanese, does not visit places you can not go by yourself but can be quite informative if you understand the language.

Two buildings can be visited, while the others can only be seen from outside - unfortunately.

Image 682East Cocoon Warehouse (東繭倉庫)

First building seen by visitors, as it is located just in front of the main entrance, this large warehouse (12m 104m) is constructed in an original style, copying with some modification the French construction techniques. Bricks are framed with wooden beams. And while only bricks of same size are used, but they are placed alternatively on their large and small size; since those size have a 2:1 ratio, it creates a typical design which is often found in Europe, but virtually unknown in Japan.
The first part of the silk production was taken on the second floor of that building.

The silk comes from cocoons built by silk moth pupae, who were grew up in that building. For 6 weeks, the pupae ("silkworms") eat mulberry leaves, when it reaches a length of 7.5 cm, it starts to build its cocoon made of one silk filament; this process takes 3 days, and the length of the filament produced reaches almost 1000 meters! Before the moth hatches, it is killed by hot water or vapor to preserve the cocoon. The cocoon were then transfered to the Manufacturing Plant building.

Image 683Manufacturing Plant (繰糸場)

The largest building (12.3m140m), where the production of silk thread was made. The process is quite simple... at least theoretically. Cocoons are brushed to get some filaments, which are joined together and wound on a wheel. To produce 1 kg of raw silk, around 5500 cocoons are required.

The great think in that building is that the silk reeling machines used for the production are still there, and can be observed in details (they are unfortunately covered with some transparent plastic sheets, probably to preserve them better). A TV screen presents a 3-minutes movie to describe all steps in details. There are about 7 production lines - all looking quite similar - in that building.


Image 684Brunat House

This elegant building was used by Paul Brunat himself, and later became a cultural center. Visitors can not go inside, though... In the immediate vicinity is the doctor's office, as well as a small hospital.




West Cocoon Warehouse (西繭倉庫)

Another large warehouse - which has the same dimension as the East one. Again visitors are not allowed inside, but can appreciate the size from outside. In this building, the moths were nursed on the upper floor, while coal was stored on the ground floor.


Image 681Administrative Buildings

Built only 1 year after the factory itself, those buildings are much more elegant - a clear sign that the construction techniques improved during this small laps of time.
