This natural hot spring draws from the inn's own source, which boasts a generous flow of 200 liters per minute, and is luxuriously poured into the baths without any added water or heating. The men's bath features a rugged rock bath, while the women's bath has a cypress open-air bath, allowing guests to enjoy a soothing soak while listening to the pleasant murmuring of the Yukawa River flowing right beside it. The water is silky and very gentle, and it leaves the skin moisturized with a beautifying effect. Thanks to its excellent heat-retaining properties, the warmth lasts long after you get out of the bath.

A source-fed private bath where you can indulge in hot spring bathing in a private setting. Guests staying in the South Wing or East Wing can use it free of charge, with same-day front desk reservations required. The same fresh, skin-beautifying water as in the large bath flows continuously, letting you enjoy its silky, gentle feel with family or someone special without any concern. The property also offers luxurious guest rooms with private open-air hot spring baths, where you can enjoy the source-fed waters at any time in your room.
