01 / Kuki-Ōbayashi Silver Mine Ruins

More than 1,500 mining and smelting tracesremain around Iwaya, Ōbayashi, and Kuki.

The mine is thought to have been developed on a large scale by Mōri Motonari in the mid-16th century. It thrived as shogunate-controlled land in the Edo period, and was redeveloped in the Meiji era by the Hori family of Tsuwano. In October 2021 it became Onan's first National Historic Site.

  • Over 1,500 mining and smelting remains
  • National Historic Site since Oct. 2021 (Onan's first)
  • The 10th mining-related National Historic Site in Japan

Onan lies near the center of Shimane Prefecture, opening into basins within the Chugoku Mountains. Most of the town sits between 100m and 600m in elevation, with steep 1,000m-class peaks to the south and west. It was formed on October 1, 2004, from the merger of Hasumi Village, Mizuho Town, and Iwami Town. With no train station, the town-run Onan Bus is how residents get around.
