A scenic observation bath for men called Sōkai and for women called Hekiten, with a magnificent front view of Izu Oshima. The indoor bath is fed by the abundant private spring Yahata no Yu, with 150 liters per minute and a source temperature of 98.5°C, into spacious tubs befitting a large public bath. This natural hot spring is neither diluted nor reheated. The indoor bath uses a combination of free-flowing and circulation systems, while the open-air bath is free-flowing only. It is a renowned spring with excellent benefits for recovery from fatigue and sensitivity to cold, allowing you to enjoy a luxurious soak surrounded by the vast sea and sky.

Four private baths with different atmospheres, inspired by the growth stages of a camellia: Seed, Sprout, Bud, and Flower. Each space is carefully designed with attention to layout, materials, and small details, and you can exclusively enjoy the private spring Yahata no Yu in a free-flowing style. For example, Seed is a quiet, dark space inspired by waiting to sprout underground, where you can enjoy the ripples of water reflected on the ceiling. It is the ideal premium area for savoring freshly sourced famous water in your preferred private setting.
