This Finnish-style dry sauna is located next to the large bath, and its high-quality wooden aroma pleasantly stimulates the nose. Large glass windows in the sauna room overlook the outdoor terrace and beautiful forest, letting guests soak up a gentle stream of sunlight during the day and the quiet Karuizawa nightscape at night while breaking a sweat. With just the right level of heat that encourages firm perspiration without feeling suffocating, it slowly releases both body and mind from tension.

Located alongside the dry sauna inside the large bath area, this steam sauna is filled with gentle, high-quality steam. It warms the body deeply and softly without placing excessive heat stress on it, making it easy to work up a light sweat throughout the body. It is designed to offer skin-beautifying and relaxing benefits, allowing even those who are not fond of hot saunas to enjoy soothing comfort at length.

This clean and highly stylish cold plunge bath is located close to the sauna room. Managed at a crisp but mellow water temperature that suits Karuizawa’s cool air, it firmly tightens the body after the sauna and encourages cooldown. Because it is not set to be overly cold, even sauna beginners can use it comfortably, and it smoothly leads them into a refreshing outdoor bathing experience afterward.
