Hijiori volcano is a caldera about 15 km northeast of Gassan volcano in Yamagata Prefecture in northern Honshu, Japan.
It formed about 12,000 years ago during an eruption that produced dacitic pyroclastic flows and tephra fall to the east until the Pacifi Ocean. A lava dome grew at the end of the eruption.
There are many hot springs at and near the volcano. These are among the main attractions of the area.
