The development and utilization of geothermal energy during the period from 1970 to the end of 1983 are reviewed emphasizing geological stand point, in other words, geothermal exploration and resource assessment. The investment of large-scale research and development (R & D) has been made since the outbreak of "oil crisis" and presently geothermal R & D are being promoted mainly under the national project. By the geothermal survey selecting thirty major geothermal areas in Japan, the assessment of geothermal resources was done on the basis of the surface manifestations. During the period, depths of geothermal reservoir as exploration target increased and thus for the understanding of regional and deep geothermal systems, various geothermal exploration techniques have been applied. Geothemlal R & D are being most intensively conducted in the Hachiman-tai volcanoes and adjacent area in the backbone range of Tohoku District and in the Hohi volcanic region of northern Kyushu. The progress of geothermal exploration of both areas is reviewed and the former area includes the Matsukawa geothermal plant, the first geothermal power plant in Japan, its fluids characterized by vapor-dominated system, and the latter includes the Otake geothermal plant, the second plant and hot-water system. As a result of geothermal development and utilization in terms of electrical output, capacity output of 32MW at the beginning of 1970 increased to 228MW at the end of 1983.
