Capacity6people
A high-temperature dry sauna in the men's large public bath, with a clean, woodsy atmosphere. Humidity is kept low, and the dry, comfortable heat wraps around your entire body. It gently warms you from deep within, letting you forget the everyday and enjoy a refreshing sweat-drenched detox to your heart's content.
Sauna TypeMist Sauna
A soft mist sauna adjacent to the women's large public bath, with water turned into a fine mist. The high humidity means you can breathe comfortably, and it is extremely gentle on the body, allowing you to warm up slowly and without strain. Together with the skin-beautifying hot spring, it offers an exquisite hydrating experience.
A cold plunge bath installed right next to the men's large public bath sauna room, renovated in July 2024. The crisp, clear water feels gentle on the skin and cools down your overheated body after the sauna in an instant. After you refresh yourself, you can enjoy a relaxing outdoor air bath while feeling the pleasant sea breeze at the Infinity Sky Open-Air Bath.
