Dashidaira Dam

Dashidaira Dam is a concrete gravity dam built across the Kurobe River to generate electricity in a mountainous area of central Japan. The structure holds water in a reservoir that feeds the power plant below.

The dam was completed in 1985 as part of a major push to develop hydroelectric power in the Kurobe Valley during Japan's period of rapid industrial growth. Earlier projects in the river valley had paved the way for this later construction.

The dam represents a milestone in Japanese engineering, demonstrating the nation's expertise in hydroelectric infrastructure within mountainous terrain.

The site offers several viewing spots where you can see the dam and the surrounding mountain landscape clearly. The best views come from marked observation areas near the road alongside the structure.

The dam employs a specialized system that automatically releases excess water during heavy rainfall while keeping power generation steady. This dual function shows an engineering solution designed specifically for the challenges of mountain rivers.
