About

Katta-no-yu is a large bathhouse complex rather than a natural hot spring: the water here isn't drawn from a real onsen source, but there's still plenty to soak in. The indoor baths include a jet bath, an artificial carbonated bath and an ultrasonic bath, alongside an open air rotenburo and a cold plunge. Three separate sauna rooms cover different styles: a stadium style sauna, a bincho-charcoal (備長炭) and aromatherapy sauna that swaps between the men's and women's sides each month, and a salt sauna. Private family baths can be rented, and there's a restaurant and a relaxation lounge for afterward. A capsule hotel operates on site for overnight stays.
