Introduction of the Accommodation

Open-air Onsen bath

Open-air Onsen Bath: “A Soak That Blends into the Forest with Views of Mt. Asama”

An open-air bath with views of Mt. Asama and a sweeping panorama stretching to the townscape of Komoro. Soak in an airy, natural-stone tub and enjoy breathtaking seasonal scenery of the Asama mountain range. The waters of Nunobiki Onsen are chosen not for showiness, but for their gentle comfort. This mildly alkaline water (pH 8.33) softens and conditions the skin, leaving it silky-smooth to the touch. Surrounded by forest, take a quiet moment to warm your body from the core at an unhurried pace. Here, time flows for you to reset and feel restored.
