Abstract
The present situation of the geothermal field developments in Japan is such that eight geothermal power stations are being operated, while there are still many geothermal areas to be explored. Up to this day, the target of geothermal exploration has mainly been the areas by surface geological survey and the existing geothermal reservoirs are located not deeper than 1,500m depth. Recent geothermal energy development shows a trend from the study on vapor dominated or liquid dominated hydrothermal resources in shallow zones to that on hydrothermal resources in deeper zones. Exploration wells of 3,OOOm depth class have been drilled in Japan.
