About Amagase Dam

Located in the central Kinki region, the Yodo river system originates in Lake Biwa, from which the waters that will eventually become the Yodo River flow as the Seta River and then as the Uji River before combining with the Kizu River from the south and the Katsura River from the north to form the Yodo River, which empties into Osaka Bay.
A large number of people living in the Kinki region make use of the river’s water.

The system as a whole includes seven dams and two floodgates, but Amagase Dam, a multipurpose dam that was completed in 1964, is the only dam on the Uji River, which comprises the main river of the Yodo River.

The dam is a dome-shaped arch dam, and its lake is known as Lake Ho-o, meaning “phoenix,” because it resembles a bird spreading its wings when seen from downstream.
