Travel Guide - Shiromaru Dam


In the upstream region of Hatonosu-keikoku Valley sits Shiromaru Dam, which was constructed in 1963 and holds back the Tama-gawa River. The dam has a underground facility called "Gyodo" where you can watch passing school of fish from the Tama-gawa River to the dam lake.
Further upstream from the dam lake is Kazuma-kyo Gorge. One of Okutama's most peaceful valleys, the area is very popular among fishers.
