Sado Gold Mine

Located on Sado Island in the west of Niigata Prefecture is Sado Gold Mine, Japan’s largest gold and silver mine. Noted for its impressive excavated tunnels stretching for approx. 400km, the mine has approx. 800 meters deep gold-bearing veins expanding approx. 3,000 meters from east to west, and approx. 600 meters from south to north.

Mining began at Sado Gold Mine on a full scale from 1601. The mine remained open until 1989, when its reserve of resources were completely depleted. During that time, approx. 78 tons of gold and approx. 2,330 tons of silver were mined from the area.

The Sado Gold Mine tunnels and facilities for mining, smelting and other activities have been designated as a National Important Cultural Property of Japan, Historic Site, and Heritage of Industrial Modernization. The mining relics and technologies used during its operational period are open to the public for viewing.
