The Tomioka Silk Mill is the symbol of "Silk Country" Gunma. It was funded as a government-operated silk reeling factory in 1872. After being sold to the private sector in 1893, it continued to operate until its closedown in 1987. It contributed to developing silk mass production technology. As a result, silk became available to people worldwide, which led to the inscription of Tomioka Silk Mill and Related Sites including Tajima Yahei Sericulture Farm, Takayama-sha Sericulture School and Arafune Cold Storage as World Heritage Site, and the mill was designed as a National Treasure for the first time in Gunma in 2014.
