⛏ Ashio Copper Mine

The Ashio Copper Mine is a former copper mine located in the town of Ashio, Tochigi, in the northern Kantō region of Japan. It was the site of Japan's first major pollution disaster in the 1880s and the scene of the 1907 miners' riots. The pollution disaster led to the birth of the Japanese environmental movement and the 1897 Third Mine Pollution Prevention Order. It also triggered changes in the mine's operations, which had played a role in the 1907 riots, part of a string of mining disputes in 1907. During World War II the mine was worked by POW forced labor.
