Sakaigawa Dam

Sakaigawa Dam is a gravity dam built across a river in the mountainous region between Nanto and Shirakawa in Gifu Prefecture. The structure holds back water to create a reservoir that supplies the surrounding area with resources for farming and electricity generation.

Construction began in 1973 and the facility started operating in 1993 after taking about two decades to complete. The project was part of infrastructure development in the region and helped modernize the local economy.

The dam contributes to regional development by providing essential water resources for agricultural activities and supporting local farming communities in Gifu Prefecture.

The site is located in a mountainous area and is best reached during daylight hours when roads are clearly visible. Visitors should be aware that the region can have snowy winters and some access roads may be limited during certain seasons.

The dam maintains a hydraulic head of 216.7 meters and creates a reservoir with a surface area of 1.60 square kilometers.
