The municipality of Isa is located in the southern part of Kyushu Island, and it is considered one of the wealthiest places in Japan because one of the most important gold mines is found in this area, Hishikari mine. Until now, the geothermal resource has not been used for power generation purpose although Geological Survey of Japan had carried out some preliminary geothermal assessments, which show that the power potential density is around 20 kW/km2. To calibrate the previous value, first, this study pretends to analyze the gravity data for figuring out geothermal reservoir border and the assessment of geothermal potential. For this purpose, an area of 10 x 10 km was selected. The Bouguer Anomaly result shows a high value in the center which extends 5.61 km2 wide and represents the possible geothermal reservoir. Therefore, using this value, the power potential assessment was 107.6 kW/km2 for 20 years.
