The Maruyama Dam (丸山ダム Maruyama Damu) is a dam on the border of Mitake and Yaotsu in Gifu Prefecture, Japan. It was built on the upper reaches of the Kiso River system. It is a gravity dam that is 98.2 m (322 ft) tall. It was built after World War II as part of a large, nationwide dam building project.
