Tomioka Silk Mill: Tomioka Silk Mill was established in 1872 by the Japanese government, with an aim to realize the mass-production of the silk, as well as to improve the quality of this principal export item of Japan at that time. It was equipped with the Western silk-reeling technology, and became a model for other silk mills founded in various regions after that. It had been working also on the breed improvement of silkworms, and played a central role in developing the silk industry in Japan. The original main buildings, such as East Cocoon Warehouse, are still well preserved, though it finished the operation in 1987. It was designated as a National Historic Site in 2007, and as a National Important Cultural Property in 2008.
Female Worker: It is said that more than 400 women workers recruited from all over Japan had learned the techniques of machine-reeling here and became leaders of silk industries in their home towns with great contributions.
