Nagawado Dam, Hydroelectric dam in Nagano Prefecture, Japan.
Nagawado Dam is a hydroelectric facility on the Azusa River in Nagano Prefecture that creates a large reservoir in the mountains. The structure harnesses the river's flow and elevation change to generate power for the surrounding region.
Construction began in 1961 and finished in 1969 during Japan's rapid post-war infrastructure expansion. This project was one of many energy facilities built to support the nation's growing industrial and urban development.
The dam represents Japan's commitment to hydroelectric power generation, reflecting the national focus on sustainable energy solutions within mountainous terrains.
This facility sits in a mountainous area with limited public access to the main structure itself. Visitors interested in the location can explore the surrounding landscape, though mountain weather can change quickly.
This dam is one of three interconnected facilities on the Azusa River that work together as a power system. The trio uses pumped-storage technology, moving water between reservoirs to meet electricity demands during peak hours.
