Geothermal Resources in Japan

Japan has many volcanoes, and as many hot springs and geothermal areas that are associated with—and are the gift of—the volcanoes. Eighteen geothermal power plants use geothermal heat in Japan. Here, we illustrate how a geothermal power plant operates in the Hachimantai volcanic group that extends from Akita Prefecture to Iwate Prefecture. Rock and minerals characteristic to the geothermal areas are exhibited on the left.
