Midagahara volcano is a dissected andesitic-to-dacitic stratovolcano on a plateau surrounded by high peaks of the North Japan Alps. The granite-and-gneiss peak of Tateyama lies immediately to the east. Formation of a 4-km-wide erosional caldera was followed by repeated eruptions of lava and pyroclastics forming the Midagahara plateau that was later dissected by the Yukawa river. Holocene eruptions have been restricted to small phreatic explosions that formed craters. A minor historical eruption occurred in the 19th century. An earthquake swarm took place in 1990. Hot springs occur in seven locations on the floor of the poorly defined erosional caldera.

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

Lake-filled Mikuriga-ike explosion crater is part of Tate-yama, a dissected stratovolcano on a plateau surrounded by high granite-and-gneiss peaks of the North Japan Alps. Formation of a 4-km-wide caldera was followed by repeated Pleistocene eruptions of lava and pyroclastics forming a plateau that was later dissected by the Yu-kawa river. Holocene eruptions have been restricted to small phreatic explosions that formed craters, such as the one seen here. Hot springs occur in seven locations on the floor of the poorly defined caldera.
