The central public bath of Wakura Onsen, a town with over 1,200 years of hot spring history. The spring is said to have been discovered when a fisherman saw a heron healing its leg in the warm coastal water—a rare seaside onsen in Japan. Soyu has served as the shared bath for both locals and travelers since the Meiji era.

The current building blends modern facilities with a traditional role: it’s where people come for their daily bath, for conversation, and to soak in natural hot spring water that flows straight from the source. If you’re passing through Wakura, this is where you get a feel for the town’s rhythm.
