The Tomioka Silk Mill and Related Industrial Heritage

The Tomioka Silk Mill and Related Industrial Heritage (富岡製糸場と絹産業遺産群) is a grouping of sites that relate to the industrialization of Japan in the Meiji period, part of the industrial heritage of Japan. The Tomioka silk mill was constructed in 1872 in Gunma Prefecture, which became a leading centre for sericulture, the rearing of silkworms and production of raw silk. In 2007 the monuments were submitted jointly for inscription on the UNESCO World Heritage List under criteria ii, iv, and v. Ten component sites have been proposed (listed below). Four sites were retained in Tomioka Silk Mill and Related Sites in 2014:
 * 1) Tomioka Silk Mill
