Hiuchi volcano is a stratovolcano located in Niggata Prefecture, 140 km NNW of Tokyo. It is part of the Nikko National park, one of Japan's most scenic regions, known for Lake Ozenuma, a popular hiking destination in the park.
The last eruption was in 1544 from the Miike lava dome at the southern end of Hiuchi's summit.

Beschreibung:

Hiuchi volcano started to form about 350,000 years ago. A major plinian eruption occurred about 170,00-160,000 years ago and produced 8 cubic km of tephra (the Hiuchigatake-Nanairi tephra) and large pyroclastic flow deposits.

The youngest volcanic feature of Hiuchi volcano are 2 lava domes at the southern end of the summit complex. The southern dome, Akanagure, was active about 3500 years ago. It produced viscous lava flows extending to the southern and western flanks the volcano.
The younger dome, the Miike lava dome, is located 300 m south of Manaitagura peak, and the probable source of the volcano's last reported eruption in 1544.
