♨️Hot Spring Information
♨️
Sanda Onsen Well No. 1
Natural 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.
