The famous Sarugakyou hot springs are located adjacent to the lake created by the dam—Akaya Lake. The hot spring facilities were originally located adjacent to the Akaya River, but submerged as a result of the dam's establishment, similar to Yanba Dam and the Kawarayu hot springs. However, in the case of Sarugakyou, the source of the hot spring was preserved, allowing for the development of a new hot spring resort area, and many hotels and inns sprung up around the shores of Akaya Lake, drawing numerous hot spring tourists to Gunma Prefecture.
