Tomioka Silk Mill

Tomioka Silk Mill, established in 1872, put Gunma on the map as a center for Japan’s textile industry. As the country’s first modern silk-reeling factory, it played a pivotal role in Japan’s industrial revolution during the Meiji era (1868–1912), using cutting-edge machinery to improve silk quality and working conditions. Today, this well-preserved factory is a UNESCO World Heritage Site, offering visitors a glimpse into Japan’s transformation into a global silk powerhouse.

A short walk from Joshu-Tomioka Station, the area surrounding the mill is a blend of history and modern design. The red-brick Tomioka Silk Mill, built by Japanese craftsmen under the guidance of French engineers, showcases a unique fusion of Japanese and Western architectural techniques. Near the station, the old Tomioka Warehouse complex—originally constructed in the early twentieth century—was revitalized by renowned architect Kengo Kuma. These buildings now house the Gunma Prefecture World Heritage Visitor Center, a cafe, and a store where visitors can buy local souvenirs. The warehouse complex also features a grassy plaza that hosts regular markets and events.

Tomioka City Hall itself is a contemporary landmark that complements both the historical mill and the surrounding retro-modern streetscape. Even the station building reflects the city’s silk heritage, featuring a rare steel-framed brick construction inspired by the mill’s timber-framed brickwork. Just two hours from Tokyo, Tomioka is a walkable town where past and present come together.
