A full-fledged dry sauna, also known as a bona sauna, with the sauna heater built beneath the seating. Because the heat source is not exposed, the room’s temperature and humidity are kept even, making it easier to breathe. The pleasant warmth that gently rises from the benches warms the body thoroughly and softly from the core. While feeling the warmth of the wood and relaxing to calm background music, you can enjoy a generous and satisfying sweat.

A moisture-rich aroma mist sauna, where fine mist at a low temperature pleasantly fills the room. The gentle fragrance of aromatherapy relaxes the mind, and by breathing deeply and inhaling the mist, you can refresh yourself from within. This meditative space is especially recommended for those who are not fond of the strong heat of high-temperature saunas, or for those who want to warm up slowly and give their skin a high level of moisture.

A cold plunge bath located inside the large public bath, right near the sauna and aroma mist sauna. It offers a crisp coolness that quickly cools down a body heated to the limit in the sauna, while maintaining just the right temperature so it never feels too cold and remains pleasant to enter. Its mild, enveloping texture spreads a refreshing sense of renewal. After the cold plunge bath, you can enjoy the best outdoor air bath in the Wellness Living Room, where the modern design of the open-air area stands out, while feeling Hakodate’s pleasant sea breeze.
