Cave BathAbout
The baths at Mercure Kochi Tosa Resort & Spa sit high enough to look out over the Pacific, and the outdoor rotenburo uses natural spring water from the hotel's own source. There are two outdoor zones, Katsurahama and Muroto-misaki, which rotate between men and women each day; the Muroto-misaki side has a cave bath tucked into the rock. Indoor baths, a dry sauna, and a cold plunge round out the facilities. Day-use visitors are welcome in the evenings.
