The Akan River rises from Lake Akan, 420 metres (1,380 ft) above sea level. The lake formed when the Akan River was damed by an eruption of Mount Oakan some 6000 years ago. The river exits the lake at Takiguchi as a waterfall. This spot and Takimi Bridge nearby are attractions in Akan National Park.
