Tomioka Silk Mill is a former silk-reeling factory in Tomioka, Gunma, and a UNESCO World Heritage site. Opened in 1872, it was Japan’s first modern silk factory, built with French expertise and machinery. Walk through preserved red-brick buildings, including the cocoon warehouses, and see exhibits on silk production and the lives of the women who worked here. Start at the West Cocoon Warehouse for English-language displays; the site is large, so allow time to explore its different sections.
A model factory opened in 1872
The Meiji government established Tomioka Silk Mill in 1872 to modernize silk production. Before its opening, silk yarn was made with a simple hand-operated machine called a zaguri, which limited production speed. The new factory used modern machinery and French expertise to produce raw silk on a larger scale.
French engineer Paul Brunat led the mill’s operations in its early years. The factory was part of a broader effort to improve the quality of Japanese silk and expand modern industry. Its production methods also helped shape silk factories elsewhere in Japan.
Buildings that remain from the original mill
Several structures built when the mill opened can still be seen, including the East and West Cocoon Warehouses, the Director’s House, also known as the Brunat House, and the French Female Instructors’ House. The Director’s House was among Japan’s early Western-style residences.
The factory buildings combine traditional Japanese framing methods with brick façades. The red-brick warehouses are among the site’s most recognizable structures, while the surviving production buildings help show how the factory was laid out.
Silk production and workers’ lives
Exhibits explain the process of turning silkworm cocoons into raw silk and the machinery used in production. Displays also bring attention to the young women who worked at the mill, including their daily lives and their role in Japan’s industrial development.
The West Cocoon Warehouse is a useful place to begin because it has English-language displays. English explanations are not available in every early room, so an audio guide app can add context as you move between buildings. The site has several sections to explore, and it is easy to spend longer in one area than planned.
