Tomioka Silk Mill, established in 1872 as Japan’s first government-run modern silk-reeling factory, played a pivotal role in Japan’s rapid industrialisation during the Meiji era, employing French engineering expertise alongside traditional Japanese wooden-frame construction techniques. Remarkably well preserved, the mill’s brick-and-timber cocoon warehouses and reeling plant were designated a UNESCO World Heritage Site in 2014, and the site’s annual autumn Silk Festival celebrates the region’s silk-producing heritage with demonstrations and local crafts.
