Niigata-Yake-yama volcano is located in the Niigata prefecture in central Honshu, near the Japan Sea. It is one of several Japanese volcanoes named Yake-yama ("Burning Mountain"). It is a very young andesitic-to-dacitic lava dome. A large explosive eruption in 887 AD produced a major pyroclastic flow which traveled 20 km to the sea.

Background
The small volcano rises to 2400 m and was constructed on a base of Tertiary mountains 2000 m high beginning about 3100 years ago. 3 major magmatic eruptions took place in historical time, producing pyroclastic flows and surges and lava flows that traveled mainly down the Hayakawa river valley to the north and NW.The first of these eruptions took place about 1000 years ago (in 887 and possibly 989 AD) and produced the Hayakawa pyroclastic flow, which traveled about 20 km to reach the Japan Sea, and the massive Mae-yama lava flow, which traveled about 6.5 km down the Hayakawa river valley. The summit lava dome was emplaced during the 1361 eruption, and the last magmatic eruption took place in 1773 AD. Eruptive activity since 1773 has consisted of relatively minor phreatic explosions from several radial fissures and explosion craters that cut the summit and flanks of the dome.
