Washi Dam, Hydroelectric dam in Ono, Japan.
Washi Dam is an arch-gravity dam located on the Kuzuryu River in Ono that stores water and generates electricity. This type of structure combines two engineering approaches to handle water pressure effectively.
Construction of Washi Dam began in 1957 and the facility started operating in 1968 under the Electric Power Development Company. It was part of Japan's expansion of hydroelectric power during that era.
The dam infrastructure represents a milestone in Japanese engineering, demonstrating the nation's commitment to sustainable power generation through hydroelectric facilities.
The dam is visible from outside and the site offers viewpoints where visitors can see the structure and reservoir. It helps to wear comfortable shoes since paths around the area can be hilly.
The facility is part of a pumped-storage system that works alongside nearby Kuzuryu Dam, allowing energy to be stored and released flexibly as needed. This coordination of multiple dams across the region makes the system especially efficient for power supply.
