Historical Context
Postwar Infrastructure and Regional Impact
Futase Dam’s construction was part of Japan’s broader postwar reconstruction, addressing urgent needs for flood mitigation, water management, and electricity. The Arakawa River, historically prone to flooding, threatened both local communities and the Tokyo metropolitan area. The dam project provided employment, modernized Chichibu, and turned the area into a scenic and recreational destination (Wikipedia, Japanrar).
Engineering and Environmental Features
Structure and Function
- Type Arch-gravity dam—combines the strength of an arch with gravity-based stability, ideal for the narrow, rocky Arakawa valley (Wikipedia).
- Dimensions Reservoir covers 76 hectares, stores up to 26.9 million cubic meters of water, with a 170 km² catchment area.
- Purpose Flood control, agricultural irrigation, and hydroelectric power generation for the Chichibu basin and beyond (Japanrar).
Environmental Stewardship
Sediment accumulation threatened the dam’s efficiency. Since 2003, innovative sediment management—including ecological monitoring and controlled sediment release—has helped restore river health and support local wildlife, such as the Japanese fluvial sculpin (Kensetsukankyo Research Report on Sediment Management).
