Day trip from Hokkaido, Hokkaido
Lake Toya and Showa-shinzan
Lake Toya (Toya-ko) is a circular caldera lake formed 110,000 years ago in the Shikotsu-Toya National Park, with a cluster of islands in its centre and the active Usu-zan volcano on its southern shore. Showa-shinzan, a parasitic lava dome that erupted from a wheat field between 1943-1945 and grew to 398m, is nearby and accessible by ropeway. The lake area combines volcanic scenery, hot spring bathing at lakeside onsen resorts, and the fascinating story of Usu-zan's recent eruptions (2000 and 1977).
