Koyadaira Dam, Concrete gravity dam in Kurobe, Japan.
Koyadaira Dam is a concrete gravity structure in the Kurobe mountains that harnesses water to produce electricity for the surrounding area. The construction uses the weight of the concrete wall itself to resist the water pressure behind it.
Construction started in 1936 as part of Japan's drive to expand hydroelectric power generation in mountainous areas. The project came during a period when the country was rapidly building up its industrial infrastructure.
The dam represents Japanese engineering excellence, demonstrating the nation's capacity to build substantial infrastructure projects in mountainous terrain.
Visitors can explore the area from designated viewing points that offer views of the dam structure. It is best to visit during months with milder weather, as the mountains can become difficult to reach in winter.
The dam's position in the Kurobe mountain range allows it to harness water resources while functioning as part of an integrated hydroelectric network.
