The silver mine of Ikuno was found in 807 (Heian era). In 1542, during the Muromachi period, the governor of Tajima, Suketayo Yamana, begun the exploitation of the silver mine of Ikuno. Under the power of Nobunaga Oda and Toyotomi Hideyoshi, the Bakufu of Edo appointed magistrates to oversee the mine. Afterward, governors were appointed and soon, the silver mine of Ikuno reached the peak of its activities.
The mine was declared an Imperial Estate and placed under jurisdiction of the Imperial office of the Imperial Household Ministry in 1889. After, in 1896, the Ikuno’s mine was sold off to the Mitsubishi Company and became one of the leading producing mine in Japan. The mine closed in 1973 and the long story of Ikuno Mine came to its end.
At the close time, the deepest and longest shaft measured more than 350 km and reached a depth of 880 meters. During the long activity of the mine, more than 70 types of minerals have been extracted.
