Origins of Iwami Ginzan Silver Mine

1527

The Iwami Ginzan Silver Mine is in Ōda, Shimane Prefecture, in western Honshu, and was one of the largest silver mines in the world in the 16th and 17th centuries. Large-scale production began after the merchant Kamiya Jutei brought in a refining technique from Korea, and the mine supplied a significant share of the silver that circulated in East Asia and was exported to Europe, where it appeared on Portuguese maps as the Silver Mines. It came under the control of the Tokugawa shogunate. Mining continued on a smaller scale until it ended in 1923. UNESCO inscribed the mine and its cultural landscape in 2007, noting how small-scale, sustainable operations preserved the surrounding forests.
