Steam rises from a geothermal plant on the N side of Nigorigawa caldera in SW Hokkaido. The caldera, located along the shores of Uchiura Bay WNW of Hokkaido-Komagatake volcano, formed during a major explosive eruption about 12,900 ± 270 years ago. The flat caldera floor contains the town of Nigorigawa.
