Funagira Dam, Gravity dam in Shizuoka, Japan
Funagira Dam is a concrete gravity structure spanning the Tenryu River at 24 meters high, equipped with large roller gates to control water flow. The facility generates electricity, supplies irrigation water and drinking water to local communities, and supports industrial water needs.
Construction began in 1972 and finished in 1977 as part of Japan's post-war infrastructure expansion. This project reflected broader investment in dam building across the Shizuoka region during that period.
The dam includes a fish ladder with special lighting that helps hundreds of thousands of ayu fish move upstream each year.
The dam is accessible to visitors, with the best views from the top of the structure where you can observe the water management systems and reservoir. The area is quiet and works well for quick visits or photography, especially when light conditions are favorable.
The structure features one of the world's largest roller gate systems, making the gates dominate its visual appearance. This distinctive design approach makes it stand out compared to typical dam constructions.
