A full-scale Finnish-style sauna renovated in 2024. It features an auto-löyly function that automatically pours water every 30 minutes, surrounding your whole body with a pleasant wave of heat and encouraging efficient sweating. The room is a clean, wood-scented space, and the refreshing mint aroma enhances relaxation. In the quiet that only a top-floor setting can offer, you can calmly turn inward and face yourself. The appeal lies in being able to savor the latest sauna experience in the relaxed atmosphere of a long-established ryokan.

The cold plunge bath located right next to the sauna is supplied with constantly flowing water, so you can immerse yourself in fresh, clean water at all times. The water temperature is cool but not too cold, making it easy for beginners to enter. It gently wraps around a body heated by the sauna and helps you cool down slowly. Though compact, the tub offers a pleasantly refreshing touch that leads naturally to the open-air bathing area afterward. Combined with open-air cooling under the Kochi sky, it guides you to a blissful state of totonou.
