Miboro Dam (御母衣ダム, Miboro damu) is a dam on the Shō River in Shirakawa, in Gifu Prefecture Japan. It supports a 256 MW hydroelectric power station. Of the nine dams on the Shō River, it is the furthest upstream.[1][2]

The dam flooded several villages and shrines, submerging them completely, two cherry trees were taken from one of the submerged shrines and placed in Shirakawa-go where it is said that each petal represents a memory from someone who lived in the villages before they were flooded.[3]
