Iwami Ginzan once produced approximately one-third of the world's silver during the 16th and 17th centuries.
The mining town of Omori was uniquely preserved because the mine's exhaustion and the shift to modern industry led to a lack of urban redevelopment.
The site uses a specific type of 'ash blowing' refining method called 'haifuki-ho', which was introduced from China in the 16th century.
The entire site is part of a deliberate 'cultural landscape' where nature is allowed to reclaim the infrastructure to maintain historical integrity.
The mine utilized a specialized drainage system to prevent flooding in tunnels that stretched over 600 kilometers in total combined length.
The Iwami Ginzan World Heritage Center serves as the primary educational gateway to the 16th-century Iwami Ginzan silver mine, a UNESCO World Heritage site located in Oda, Shimane Prefecture. The facility uses scale models and high-definition video displays to explain the complex tunnel mining techniques and the historical socio-economic impact of the silver trade in Japan. It provides essential context for the nearby Ryugenji Mabu mine shaft, which is the only portion of the vast underground network permanently open to the public. The center features specialized exhibitions on the environmental preservation efforts that have allowed the forest to reclaim the former mining site. It is located at the entrance to the Omori silver mine district. Visitors utilize this hub to understand the scale of the former town, which once produced nearly one-third of the global silver supply during its peak. The center is integrated into the regional site management plan and serves as the starting point for trekking trails that lead to remote mining ruins.
