It is the tourist association "Lake Mashu Tourism Association" in Teshikaga Town, Hokkaido, where Lake Mashu and Lake Kussharo, which are popular tourist spots in Hokkaido, are located.
The surface of Lake Mashu boasts the world's most transparent surface, and the magnificent nature of Lake Kussharo, which is also the largest caldera lake in the Japan (a lake with water accumulated in the crater of a volcano)!
