Tomioka Silk Mill is a model factory run by the government and located in Tomioka City, Gunma Prefecture. It began operation in 1872 (Meiji 5) and played an important role in supporting the modernization of Japan and the strengthening of the nation and military. It is registered as a UNESCO World Heritage Site as the "Tomioka Silk Mill and Silk Industry Heritage Sites," and is highly regarded for the fact that the buildings from the early Meiji period have been preserved almost perfectly. It is a place that symbolizes the development of Japan's world-class silk industry, and its historical value is immeasurable.

Inside the factory, you can tour the main buildings of the time, such as the existing silk reeling mill, cocoon warehouse, inspector's house, and female factory house. In particular, the huge silk reeling mill, which is about 140 meters long, is impressive, and you can imagine what it was like when it was in operation. Part of the French-style silk reeling machine from that time is also on display, and you can learn about the history of technological innovation in Japan.
