The Taisetsuzan volcano group lies at the northern end of the Taisetsu-Tokachi graben in central Hokkaido. It consists of a complex group of stratovolcanoes and lava domes associated with a small, 2-km-wide caldera. The eight satellitic volcanoes are aligned along a ring fracture that is centered over the eastern rim of the caldera. Asahi-dake, the highest peak of the complex, was constructed 3 km SW of the center of the caldera. Other stratovolcanoes are located along a NE-SW line cutting through the caldera that trends toward the Tokachi volcano complex to the SW. In contrast to the Tokachi group, no historical eruptions are known, although the latest phreatic eruption took place sometime after 1739 AD. Fumarolic areas are located on Asahidake, where at one time sulfur was mined, and in the caldera.

A solfatara field and recent explosion craters occupy the western slope of Asahi-dake, one of the Daisetsu group volcanoes in central Hokkaido. Daisetsu (also known as Taisetsu) is a complex group of stratovolcanoes and lava domes associated with a small, 2-km-wide caldera. Asahi-dake, the highest peak of the complex, was constructed 3 km SW of the center of the caldera. In contrast to the neighboring Tokachi volcano group, no historical eruptions are known from Daisetsu.
