Overview (history, characteristics, attractions)
Ashio Copper Mine, located in Ashio Town, Nikko City, Tochigi Prefecture, is one of Japan's leading historic mining heritage sites. Copper has been produced there since the Edo period, and it was fully modernized and expanded in scale from the Meiji period onwards. Mining progressed particularly under the management of Furukawa Ichibei (Furukawa) and others, and while it contributed greatly to the development of domestic industry, pollution problems caused by mining poisoning became serious, and through the movements of Tanaka Shozo and others, it also served as a catalyst for pollution control and labor issues in modern Japan.
Currently, the mine tunnels are open to the public, and industrial remains such as the ore dressing plant and drainage facilities are available, along with a museum that conveys the history of Ashio and pollution issues, making it a very interesting spot from the perspectives of industrial, environmental, and technological history. It is also worth visiting to take in the scenery of the surrounding mountains and the views from the train window of the Watarase Valley Railway.
