Enjoy a healing soak in complete privacy.
We also have gender-separated shared indoor baths.

Five private baths
Umi (Sea)
UMI's rooftop open-air bath (private use, charged), where you can fully enjoy the healing of hot water and sea. Soak in the latest jacuzzi bath, which eases the fatigue of travel, while taking in a sweeping panorama of the ocean.
Charged and by reservation; please book at the front desk. This open-air bath is to the right at the top of the stairs in front of the 3F elevator.
Hours: 15:20–24:00 / 6:20–10:00
Fee: ¥3,300 per room, 40 minutes
Misaki (Cape)
An open-air bath designed so that, when you sink deep into the tub, the surface of the water appears to merge with the horizon. The tub is made of soft-textured Izu stone for a feeling of oneness with the sea.
Nagisa (Shore)
An open-air bath whose pride is the "lying bath" space set into one corner of its square tub. Lie back in the hot spring water and enjoy a "half-body bath" in the sea breeze.
Tsuki (Moon)
An open-air bath with a unique cross shape. The tub is made of fine granite, with seats in three of its corners, so you can watch the seabirds soar across the sky, the starry night, and the moon.
Yoshimi
A private bath with the warmth of wood, soft indirect lighting and a Japanese atmosphere. There is no sea view, but you can enjoy a moody, spacious hot spring time. The powder corner is generously sized, making it a good choice for families too.
Using Misaki, Nagisa, Tsuki and Yoshimi

Gender-separated shared baths
UMI's indoor baths, where you can relax in a calm atmosphere to the sound of the waves. There is one bath each for men and women. Enjoy the Awa Onsen water, which clings gently to the skin, for as long as you like. After your bath, free drinks are available in the 3F Free Lounge.
