Enjoy a sauna with a large window overlooking the seasons, and a natural hot spring from its own source

The dry sauna has a large window, so you can enjoy the heat while taking in the rich natural scenery of Niigata. After the sauna, cool down comfortably in the cold plunge bath. Outdoor bathing in the open-air bath area is especially refreshing. The simple hot spring that naturally wells up from underground is gentle on the skin and provides excellent heat retention.
