Asahi Dam

The Asahi Dam (朝日ダム, Asahi Damu?) is a dam in Takayama, Gifu Prefecture, Japan. It was constructed along the Hida River and is part of the vast dam system built along the Kiso River system. It is a gravity dam managed by the Chubu Electric Power, Co.


The area surrounding the Hida River is ideal for the construction of dams because of the tight gorges that increase the speed of the water flow and the melting snow off of the Hida Mountains and the Kiso Mountains that increase the volume of the water flow. It was for these reasons that the area was chosen for the development of hydroelectricity during the Taishō period in the early 20th century.
