Lake Toya-ko & Toyako Onsen Travel | Things to Do

The calm caldera lake of Toya-ko (洞爺湖) is a unique tourist spot in the western part of Shikotsu-Toya National Park. The active volcano Usu-zan (737m) has erupted four times in the 20th-century, which created Showa-shinzan (398m) next to its mountain in 1944. Great eruptions caused a lot of damage in this area, however on the other hand, volcanic activity brought various benefits such as onsen and impressive views.
