An open and spacious large public bath overlooking spectacular views of the Pacific Ocean. Natural hot spring water drawn from the source warms the body from the core. In a location so striking that the sky and sea seem to become one, you can relax deeply in both body and mind while listening to the sound of the waves.

A private open-air bath set on the rooftop. Without having to worry about anyone else's gaze, you can have the panoramic view of the vast sea and sky all to yourself. At sunset or under the starry sky, you can enjoy a special bathing experience together with scenery that changes from moment to moment.

This space features a private open-air bath beyond a garden with karesansui and earthen walls, full of Japanese aesthetic charm. After your bath, you can relax in a reclining chair on the deck and sink into the luxurious afterglow while feeling the sea breeze.
