From the rooftop open-air bath on the top floor of the building, guests can enjoy an overwhelming sense of openness and sweeping seasonal views of Hakone. The hotel offers two types of sauna: a dry sauna where you can work up a proper sweat, and a mist sauna that wraps your whole body in moisture. After cooling down in the cold plunge bath, an exceptional open-air rest in Hakone's natural surroundings awaits. In addition to private baths with free-flowing spring water and rooms with open-air baths, there are many other charms unique to a hot spring inn, such as a Japanese garden with a waterfall, a power spot, adding to its appeal.

A spacious large bath with an overwhelming sense of openness and the natural beauty of Hakone through the seasons all around you. It is filled generously with gentle alkaline simple spring water from the hotel's own source, leaving your skin smooth after bathing. The stone open-air bath set in the pavilion is fed by free-flowing spring water, allowing you to spend a blissful time relaxing in fine, famous waters.

A private bath where you can enjoy the famous waters without worrying about other guests. Each bath is generously filled with natural hot spring water flowing directly from the hotel's own source, so you can always enjoy a fresh and luxurious soak. In a calm Japanese-style space where you can relax at ease, you can enjoy an exceptional time of healing that frees both body and mind with your family or someone special.

A luxurious in-room open-air bath installed exclusively in Japanese-Western style rooms and other guest rooms. In your own private space, free from interruption, you can enjoy the natural hot spring water flowing directly from the hotel's own source as often and as much as you like while feeling Hakone's crisp air. You can lose track of time and soak in the famous waters to your heart's content, fully enjoying the ultimate private resort experience unique to a hot spring inn.

A properly heated dry sauna where everyone from beginners to experienced sauna users can sweat comfortably. It promotes blood circulation throughout the body, boosts metabolism, and lets you enjoy a refreshing sensation as sweat carries away waste products and fatigue. A cold plunge bath is located right outside the sauna room, allowing for smooth cooling down with an efficient flow.

A low-temperature sauna where soft mist, like being inside a cloud, gently envelops the whole body. It places less strain on breathing and is gentler on the skin and hair, allowing you to warm up deeply and slowly from the inside in a calm heat. Even those who do not like high-temperature dry saunas can relax comfortably and enjoy a superb, moisture-rich healing experience.
