The town of Karuizawa lies amidst highlands at an altitude of about 1,000 meters near the foot of Mt. Asama - an active volcano. Surrounded by a rich natural environment, it is one of the best-known resort areas in Japan. Heat drawn from the ground heat exchanger and through heat exchange from the hot spring runoff is pooled, and termed geothermal utilization in the wide sense. The main advantage is that a high temperature heat source is readily available throughout the year. This represents the heat source for the water-to-water heat pumps.
