Hijiori volcano, seen from the E, is a small caldera located NE of the Pleistocene Gassan volcano. The town of Hijiori lies in the left foreground along the banks of two rivers through the caldera floor. The low 2.5-km-wide caldera formed during a large eruption between about 9,500 and 11,000 years ago, accompanied by pyroclastic flows and ashfall that extended to the E and reached the Pacific coast.
