Tojo Onsen is an old sento in Osaka, a five- to six-minute walk from Tsuruhashi Station toward Momodani Station. It has a deep bath, a shallow bath, an electric bath, a jet bath, a medicinal bath, and a sauna, and the sauna is free to use. The four baths are set at different water temperatures, and Showa-era songs and J-pop play in the sauna. The sauna is kept at a low temperature, so warming up takes time.
