Welcome to Tōya-ko


Usu-zan is a mixed blessing: residents know that it will erupt again, covering their town in ash, and possibly rock; however, it was the 1910 eruption that led to the discovery of hot springs here and the development of Tōya-ko Onsen (洞爺湖温泉), the small resort on the lake's southern shore.
