Kamihikawa Dam

Kamihikawa Dam is a rock-fill dam in Yamanashi Prefecture that rises 87 meters above the surrounding landscape. The structure uses stones and gravel as its primary materials and controls the flow of the Hikawa River for water storage and management.

The dam was completed in 1999 and marked an important milestone in Japan's water management infrastructure. Since then it has served as key infrastructure for the Koshu region.

This engineering structure represents Japan's commitment to sustainable water resource management while maintaining harmony with the surrounding natural environment.

The dam is operated by TEPCO Renewable Power and serves multiple functions including power generation and flood management. Access to the site may be limited, so visiting during daylight hours is recommended.

The dam's strategic position at coordinates 35.716667°N, 138.8325°E allows it to harness the Hikawa River's flow effectively for multiple purposes.
