A spacious large public bath with an outstanding sense of openness overlooking a murmuring stream and lush forest. In addition to the fully glass-walled indoor bath, it includes the rock open-air bath, where you can feel the sound of the stream up close, and the giant cypress barrel open-air bath, wrapped in the refreshing scent of hinoki. Since its opening in 1617, you can fully enjoy the free-flowing natural hot spring water that has continued to surge forth for more than 400 years, while surrounded by abundant natural scenery.

A signature open-air bath designated as a natural monument in Asahi Town, located about a 7- to 8-minute walk from the inn along a path rich in nature. A bath is built inside a mysterious cave formed over many years by the hardening of mineral deposits from the hot spring. Guests can enjoy bathing in a powerful, untouched natural space. The spring naturally wells up from near the cave ceiling, letting you feel the breath of the ancient earth directly on your skin. This is a one-of-a-kind mixed-gender open-air bath.

A women-only open-air bath nestled along a mountain stream, a little walk from the inn and surrounded by abundant nature. Its appeal lies in the superb sense of openness, embraced by the deep surrounding forest and the clear stream of Ogawa. While listening to the sound of the murmuring water up close and gazing at the panorama of the Northern Alps, whose colors change with the seasons, you can surrender yourself to the superb free-flowing natural hot spring water and fully relax both body and mind.
