The heat wave generated by the piled sauna stones on the iki stove and rocky stove fills the room, allowing for a sharp heat experience on the upper tier and a gentle sweat on the lower tier. The löyly service (aufguss) conducted every hour at 30 minutes past the hour causes heat and steam to rise rapidly, opening up all the sweat glands in the body.

With the self-löyly system, you can pour water yourself, layering waves of humidity over dense heat for a deep sweat in a short time. Silence is required. By rotating with the large 'Netsufujimoya,' you can freely adjust the intensity of your experience. The compact space concentrates the heat, allowing for a focused session. You can adjust the balance of heat and steam at your own pace by pouring water, achieving your preferred sweating experience.

Nobehanoyu's pride, the cooling tank, draws water from underground. Positioned between the open-air bath and sauna room, it rapidly cools the body from the core right after sweating. With a depth of 90 cm, the design allows the cold to envelop your entire body. The soft water quality unique to underground water is gentle on the skin, making it less burdensome even for extended immersion.
