A windowed dry sauna adjoining the men’s large bathhouse Kosa no Yu, with a sweeping view of the sea. From the sauna room window, a panoramic vista of Mikawa Bay and the Atsumi Peninsula on the opposite shore opens up right in front of you, letting you enjoy a luxurious moment as you watch the shimmering sea while in the sauna. The quiet room has no TV or music and is filled with the scent of wood, allowing you to slowly and comfortably work up a gentle sweat.

A mist sauna adjoining the women’s large bathhouse Fuzumi no Yu, gently warming the body from the core. The room is filled with warm mist at a mild temperature, making breathing easy while softly moisturizing the skin and hair and encouraging comfortable perspiration. Please enjoy a soothing moment to slowly unwind from your daily fatigue while looking out over the beautiful sea of Mikawa Bay.

A cold plunge bath placed in the perfect flow, immediately beside the men’s large bathhouse sauna room. It is cooled by a chiller, with seasonal variation, quickly tightening a body pushed to the limit in the sauna and bringing a refreshing sense of relief. The smooth flow out to the open-air outdoor bathing area right outside is another plus, and the flawless layout leads you to an exquisite state of totonou.
