Hyogo Sanda City
Natural Hot Spring Kotobuki-no-Yu in Sanda is a day-use hot spring facility located in Sanda City, Hyogo Prefecture. The three saunas—high-temperature dry, löyly salt, and barrel-shaped—quickly draw out sweat, and the two types of cold plunge baths with varying water temperatures provide a sharp finish. The final touch is the natural chloride spring that gently envelops you, relieving fatigue from the core. The facility also includes a stone sauna, gym, book lounge, and restaurant, allowing you to spend a comfortable day from morning till night.
TypeNatural Hot Spring
Sodium-calcium chloride spring (hypertonic, neutral, low-temperature spring). The water has a salty film-like feel with high heat retention. By alternating between the strong salty 'strong salty bitter spring' and the indoor or pot bath, the release of sweat and warmth deepens in stages. After bathing, you won't easily get cold, and the feeling of relaxation from the core continues.
