Environmental issues in Japan

Environmental pollution in Japan has accompanied industrialization since the Meiji period. One of the earliest cases was the copper poisoning caused by drainage from the Ashio Copper Mine in Tochigi Prefecture, beginning as early as 1878. Repeated floods occurred in the Watarase River basin, and 1,600 hectares of farmland and towns and villages in Tochigi and Gunma prefectures were damaged by the floodwater, which contained excessive inorganic copper compounds from the Ashio mine. The local breeders led by Shōzō Tanaka, a member of the Lower House from Tochigi appealed to the prefecture and the government to call a halt to the mining operations. Although the mining company paid compensatory money and the government engaged in the embankment works of the Watarase River, no fundamental solution of the problem was achieved.

Japan is the world's leading importer of both exhaustible and renewable natural resources and one of the largest consumers of fossil fuels.
