An authentic Finnish-style sauna decorated with raw birch logs, blending the rugged character of the north with the warmth of hinoki cypress. In the dim light, you can enjoy your preferred humidity level through self-löyly. Once a week, a staff-made aroma kegel, created by freezing aromatic water into a sphere, appears, releasing the pleasant sound of ice slowly melting and a refreshing fragrance into the room.

An exceptional cold plunge bath using abundant underground water from the Taisetsu mountain range, drawn up from underground and run continuously. The women's large public bath is set at around 14 degrees. Its consistently crisp, refreshing coldness is maintained throughout the year, instantly cooling down the body after being heated to the limit in the sauna and delivering an outstanding cooldown. A totonoe space is located right next to the cold plunge bath, making for a streamlined and satisfying totonou flow.
