A large public bath on the first floor, featuring a spacious marble indoor bath and a variety of open-air baths. The water generously uses the natural source of Isobe Onsen, famous as a skin-beautifying hot spring. In the open-air area, you will find six thoughtfully designed baths for both men and women, including a fragrant cypress bath, a rustic rock bath, a unique barrel bath, and a garden bath, allowing you to enjoy a luxurious bath-hopping experience while embraced by the nature of Isobe.

Located on the second floor, this superbly scenic panoramic large public bath overlooks the clear waters of the Usui River flowing gently right in front of you. It has an indoor bath bathed in dazzling sunlight through large windows and an open-air bath where refreshing mountain breezes pass through, allowing you to enjoy the hot water in a wonderfully open setting. The highly warming natural hot spring with a smooth, silky texture helps release travel tension, and at night you can relax while gazing up at a sky full of stars.
