Located on the hotel rooftop, this sky open-air bath offers a 360-degree view of the magnificent Pacific Ocean, Izu Oshima, and more, with nothing to obstruct the scenery. It luxuriantly uses the self-springing Tamano Yu Onsen from the property as free-flowing spring water, allowing you to enjoy an extraordinary and liberating bath while gazing at the blue sea and sky during the day and a star-filled sky at night, feeling as though you are floating in the air.

Two public baths that alternate by time. Rich in metasilicic acid, a beauty-skin ingredient, they let you enjoy the hotel's private source, Tamano Yu Onsen, as free-flowing spring water that moisturizes the skin. With a lineup of distinctive baths such as a jacuzzi, a mandarin orange bath, and a reclining bath, you can enjoy your own personal hot spring tour. Stretch out in the spacious bathtubs of the public baths and slowly soothe your whole body as you are wrapped in beauty-enhancing waters.

Private family baths with open-air baths, where you can enjoy free-flowing spring water without anyone disturbing you. Families, friends, and couples can savor private hot spring time to their heart's content. At night, as their names suggest, you can look up at the beautifully twinkling starry sky and moonlight from the tranquil open-air baths, and fully enjoy the unique serenity and luxury of this extraordinary experience.
