Akan River (阿寒川, Akan-gawa) is a river in Hokkaidō, Japan. The Akan River rises from Lake Akan, 420 metres (1,380 ft) above sea level.[1] The lake formed when the Akan River was dammed by an eruption of Mount Oakan some 6000 years ago.[2][3] The river exits the lake at Takiguchi as a waterfall. This spot and Takimi Bridge nearby are attractions in Akan National Park.[3] | ||||||
