Tsubawara Dam, Gravity hydroelectric dam in Shirakawa, Japan
The Tsubawara Dam is a gravity hydroelectric structure on the Shō River in Shirakawa that rises 68.2 meters high. The dam spans more than 200 meters and uses seven tainter gates to manage water flow through the system.
Construction of the dam began in 1952 during Japan's post-war rebuilding period. It became part of an extensive hydroelectric development program along the Shō River.
The dam represents a milestone in Japanese engineering advancement, demonstrating the national commitment to sustainable energy production through hydroelectric infrastructure.
The dam supplies water to a hydroelectric power station with three-digit megawatt capacity. Visitors can view the structure from the shore and explore the scale of the reservoir.
The structure is one of nine dams in a coordinated water management system along the Shō River. Each facility works as part of an integrated network rather than as an isolated installation.
