From Wikipedia
The Hakkōda Mountains are an active volcanic complex in south-central Aomori Prefecture, Japan, in Towada-Hachimantai National Park. Often called Mount Hakkōda or simply Hakkōda (八甲田), the mountains are collectively listed as one of the 100 Famous Japanese Mountains. Its highest peak, Mount Ōdake, lies 21.3 kilometers (13.2 mi) southeast of central Aomori and 28 kilometers (17 mi) west of central Towada and has an elevation of 1,585 meters (5,200 ft). The Hakkōda Mountains are a part of the Ōu Mountains which make up part of the Northeastern Japan Arc, a segment of the Pacific Ring of Fire. The volcanic complex consists of fourteen stratovolcanoes and lava domes arranged into two volcanic groups. The Northern Hakkōda Volcanic Group emerges from the rim of an 8-kilometer-wide (5.0 mi) caldera that dates back to the Pleistocene. The Southern Hakkōda Volcanic Group predates the caldera.
