Ariakecho, Kanonji, Kagawa Prefecture
Kotohiki Kairo
The most complete single stop in Kanonji if you want natural spring water, sauna options and sunset-facing coastal scenery. It is not a pure source-flow bath: the operator uses filtration, heating and chlorine disinfection, and may add water on busy days.
