A natural hot spring where you can luxuriate in free-flowing mineral-rich fossil seawater spring water pumped from deep underground. It is characterized by a precious cloudy bath that evokes the powerful blessings of the earth, and you can soak to your heart's content in the spacious open-air bath while feeling the breeze outside.

Main BathSauna
Kero Sauna
A sauna that lavishly uses Kero, a rare wood known in Finland, the birthplace of sauna culture, as the "jewel of wood." Antique Kero is used on the walls, faithfully recreating the atmosphere of an authentic Finnish sauna. The rich aroma of wood fills the entire space, bringing a deep sense of relaxation together with the heat. You can enjoy a satisfying sweat in an immersive setting that makes you forget everyday life.
Kaldarium
A steam sauna where gently heated vapor from the walls, floor, and benches spreads throughout the entire space. The fine vapor is infused with a pleasant aroma, so you can enjoy aromatherapy at the same time as the sauna. Surrounded by mild heat and rich fragrance, you can experience the finest relaxation while gently warming your body.
Log Sauna
A full-fledged high-temperature dry sauna built by forcefully stacking and assembling logs of hinoki cypress measuring around 30 cm in diameter, making it one of the largest of its kind in Japan. Its defining feature is its heavy, authentic construction, reminiscent of the earliest form of the sauna, allowing you to feel the dynamic warmth of wood while taking in the intense heat with your whole body. It draws out a good sweat and leads you to a refreshing totonou state.
Finnish Sauna
A high-temperature dry sauna exclusively for women, where modern interiors and beauty come together in perfect harmony. In this refined and calming space, you can feel powerful heat that warms you deeply all the way to the core. While quietly facing yourself, you can enjoy a high-quality refresh time with a pleasant sweat.
Tepidarium
A skin-friendly sauna for women, characterized by mild heat that gently radiates from the walls, floor, and benches. It warms the body slowly down to the deeper layers without drying out the skin. With no feeling of breathlessness, even long stays are comfortable, and you can surrender yourself to the gentle warmth and enjoy deep relaxation.
Cool Room
A women-only cool room that quickly cools down your body after a thorough sauna session and helps tighten the skin. Even if you are not comfortable with a cold plunge bath, you can cool down pleasantly without strain, and a crisp sense of refreshment spreads throughout your body. This cool, comfortable space gently supports an exceptional totonou experience.
