Toyoha mine

Japanese: 豊羽鉱山 - とよはこうざん
Toyoha mine

This mine was located in the Jozankei area of ​​Minami Ward, in the west of Sapporo. Located upstream of the Shirai River, it was one of Japan's leading mines, producing 40,000 tons of black ore per month, which contained silver, lead, copper, zinc, and iron sulfide. Nippon Mining Co., Ltd. began mining in 1935 (Showa 10), and Toyoha Mining Co., Ltd. took over management in 1950. New veins were discovered and promising veins continued to be developed in recent years, but the mine closed in March 2006 (Heisei 18).
