Hotokebara Dam, Hydroelectric dam in Ono, Japan.
Hotokebara Dam is a gravity dam located in Ono that controls water flow through its concrete structure to generate electricity. The structure spans across the landscape and creates a large body of water behind it for power generation and water management.
The dam was completed in 1968 during Japan's rapid industrial expansion and growth period. This project helped bring electrical power to mountain regions where energy sources were otherwise difficult to access.
The dam exemplifies Japan's engineering methods for integrating water management systems within mountainous landscapes while maintaining environmental balance.
The dam is accessible by local roads and offers viewpoints where visitors can see the water surface and surrounding mountain terrain. Visitors should expect changing weather conditions in mountainous areas and bring appropriate clothing.
The gravity design of the dam uses the natural weight of concrete to resist water pressure without needing complex internal structures. This simple yet effective engineering approach has proven reliable over decades without requiring major modifications.
