Ishizuchi Sacred Spring (Niihama Onsen)
An iron-containing bicarbonate and chloride hot spring gushing from 1,000 meters underground. The slightly colored water has a smooth texture that leaves the skin silky. The salt content coats the skin, providing high heat retention so the feeling of warmth persists after bathing. You can enjoy its variety in open-air baths, Shigaraki-style baths, and barrel baths, and you can also fully experience its benefits in the spring-fed bath inside the steam sauna.
