Free-flow from source
Yokawa Onsen
A private source spring rising from 1,500 m underground, classified as a carbon dioxide, sodium chloride, and bicarbonate strong saline spring. It boasts one of the highest carbon dioxide contents in Japan, and when you soak in the water, fine bubbles cling all over your body. The combination of carbon dioxide's circulation-boosting effects and the excellent heat-retaining and moisturizing properties of the strong saline spring provides outstanding warmth and skin-beautifying benefits. You can fully enjoy superb free-flowing source water in the open-air source baths and indoor source baths of Kō no Yu and Fuku no Yu, as well as in the two family baths.
