Hiuchigatake volcano lies in Nikko National Park and erupted the 8 cu km Hiuchigatake-Nanairi tephra and pyroclastic flow deposit about 170,00-160,000 years ago. Two lava domes at the southern end of the summit of Hiuchigatake stratovolcano overlook Ozenuma lake, a popular hiking destination in the national park. The southern of the two domes, Akanagure, produced a series of viscous lava flows about 3500 years ago that extend to the southern and western flanks the volcano. The northern dome, Miike, was the source of a tephra layer correlated with a report of historical activity in 1544 (Hayakawa, 1994b).

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.

Snow-capped Hiuchi volcano rises above Ozenuma lake, a popular hiking destination in Nikko National Park, in this aerial view from the SE. Two lava domes at the southern end of the summit of Hiuchi stratovolcano have been active during the Holocene. The northern dome produced viscous lava flows about 3500 years ago, and the southern dome was the source of an explosive eruption in 1544 AD.
