Lake Kussharoko is the biggest caldera lake in Japan and located in Akan National Park, the east Hokkaido, Doto. The lake is settled in west-north area of Lake Mashuko. It is very close from Lake Mashuko to Lake Kussharoko and takes 40 minutes via Bihoro Pass from Lake Mashuko No.1 observation hill by car.
From Bihoro Pass, you can see mountain range of Mashudake and Sharidake not only Lake Kussharoko. This is a very beautiful sight in this area.
There are many hot spas around Lake Kussharoko which is not frozen in the winter so that many swans get together.
