Yotei volcano, seen here from the NW, is a symmetrical stratovolcano whose flanks are cut by deep radial valleys. The summit of the 1893-m volcano is truncated by a large crater, which has several subcraters on its NW rim. The age of the last eruption of Yotei volcano is not known.

Symmetrical Yotei volcano towers to the NW above Lake Toya, which fills the 10-km-wide Toya caldera. The caldera was formed during a major eruption about 110,000 years ago. A series of andesitic lava domes in the center of the lake form Nakano-jima island, whose forested slopes appear in the right foreground. The photo was taken from the lower flank of Usu volcano, which was constructed over the southern rim of Toya caldera.

Shikotsu caldera, seen in an aerial view from the SE with Yotei volcano on the center horizon, is a 13 x 15 km caldera filled by Lake Shikotsu. Following formation of the caldera more than 30,000 years ago, three small stratovolcanoes were constructed along a NW-trending line cutting across the caldera. Snow-capped Tarumai volcano (left center) grew near the SE rim of the caldera, along with Fuppushi volcano to its right. A third volcano, Eniwa, was constructed on the NW caldera rim, at the far side of the lake.

Yotei volcano is most symmetrical when seen from its western side, as in this view. The deep radial gullies that dissect the slopes of the volcano are less pronounced on this side.

The Fukidashi lava flow from Yotei volcano in SW Hokkaido descended to the NE foot of the volcano. Vertical cooling joints can be seen at the left in this view near the terminus of the flow. Note the person behind the tree at the lower center for scale.

Volcanoes and calderas fill much of this NASA Shuttle Radar Tomography (SRTM) image of southern Hokkaido with north to the upper left. Usu volcano (bottom center) lies south of Toya caldera. The smaller caldera to the right along the Pacific Ocean is Kuttara. Tarumai and Eniwa volcanoes lie on the estern and western sides, respectively, of Shikotsu caldera (upper right). The conical white peak at left-center is Yotei volcano; Niseko volcano is along the ridge to its left. The city of Sapporo lies at the base of the mountains (top-center).
