Vein-type tungsten deposit. The mine was started around 1912 and closed in 1983. The dumps are now forested, but collectors are known to dig (disapproved) deep holes under the tree roots to hunt for cassiterite crystals and beryllium minerals. Waste rock from this mine was used to fill a valley at the nearby Yunohana "cerasite" locality.
