Background

The cones of the Hakkoda group overly an older, 8 km wide caldera. The northern vents of the Hakkoda group located in the center of the caldera appear younger than the southern group, which buries the SE caldera wall on its SE wall.
Craters with well preserved morphologies include Hakkoda-Odake, Ido-dake, Tsurugi-dake, which has a 1 km wide explosion crater open to the north.

1997 fatalities
3 soldiers were killed by CO2 on 12 July 1997 on a training mission at the N foot of Hakkoda volcano. They had entered a depression filled by lethal concentrations of volcanogenic CO2. "In the darkness, some members of the party slipped into a depression (18 m long, 11 m wide, and 8 m deep), as did those who first tried to rescue them. The men were hospitalized on the evening of 12 July, but three lost their lives."
