A supreme free-flowing open-air bath with 100% natural spring water that blends into the spectacular scenery while you feel the sound of the rolling Kuroshio waves and the pleasant sea breeze all over your body. Fresh hot spring water that naturally gushes from the island carries a faint sulfur scent and is a beauty-enhancing bath with excellent cleansing effects. You can enjoy a luxurious soak that feels as though you are standing in the middle of the Pacific Ocean.

A spacious stone indoor bath overlooking the calm Katsuura Bay outside the window. It luxuriously uses the sulfurous sodium chloride spring from the private source on the island in a combined flow-and-circulation system. Because it contains a high level of salt, it retains heat exceptionally well, leaving your body warm and comfortable long after bathing while leaving your skin moisturized and smooth.

A reservation-only private open-air bath where you can enjoy a soak while taking in the beautiful seascape of Katsuura in complete privacy. It offers high-quality sulfurous sodium chloride spring water drawn from the island's private source as 100% free-flowing spring water. Spend relaxing, unhurried time with someone special, accompanied by the soothing sound of the waves.
