Iwami Ginzan Silver Mine
The Iwami Ginzan Silver Mine in Shimane Prefecture was one of the world's most prominent silver mines, inscribed as a UNESCO World Heritage site in 2007. Discovered in 1526, the mine reached its peak in the early 17th century, when it was responsible for approximately one-third of the world's total silver production. The mining operations utilized the innovative haiban-fuki (cupellation) refining method introduced from Korea, which allowed for more efficient separation of silver from lead ore. The heritage site encompasses the mining tunnels (mabu), such as the accessible Ryugenji Mabu, as well as the surrounding historic settlement of Omori, transportation routes, and port towns. A unique aspect of Iwami Ginzan was its early ecological management; sustainable forestry was practiced to provide a steady supply of timber for smelting without devastating the landscape. Although the mine officially closed in 1923, the preserved tunnels and shrines remain as a testament to Japan's technological and economic influence in the early modern era.
