A full-fledged dry sauna equipped with auto-löyly. Regular löyly sessions fill the room with a pleasant wave of heat, encouraging you to sweat deeply all at once. The heat feels stable and gradually warms you from the core of your body. You can relax while watching TV and wash away the fatigue of sightseeing in Chichibu with a good sweat.

A sauna installed in the women's bath where you can enjoy sweating while rubbing salt over your whole body. The low temperature allows you to warm up slowly, and the salt is absorbed through pores opened by steam, helping to leave your skin smooth and soft. Wrapped in gentle heat, it is a soothing space where you can refresh both for detox and beauty.

A cold plunge bath that refreshingly cools and tightens your body after the sauna. The spacious tub design lets you sink in up to your shoulders and enjoy a slow, comfortable cooldown. The water temperature is pleasantly crisp, with a clean coldness that is still gentle on the skin. With smooth access from the sauna area, it supports the ultimate totonou routine.
