Miboro Dam (御母衣ダム Miboro damu) is a dam on the Shō River in Takayama, in the Gifu Prefecture of 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]
