Sauna
Yase has been known as a place of healing since the Asuka period.
At moksa, the tradition and wisdom of the region's kiln-style baths are brought into the present through three fully private, reservation-only saunas under the name Jōan.
Tanjō - Purify body and mind through the power of charcoal
Hijō - Unwind and relax with the soothing aroma of cypress
Bijō - Rejuvenate your skin for a radiant glow
In a space woven from water, heat, fragrance, and light, experience the ultimate state of relaxation and harmony.
A supreme space woven from water, heat, fragrance, and light.

This sauna, produced by Mikie Sasano - the daughter of Sauna Shikiji in Shizuoka,
often hailed as a sanctuary for sauna enthusiasts -
combines professional sauna expertise with a uniquely feminine perspective,

Sauna lists
Tanjō - The essence of moksa
A dry sauna that distills the very essence of moksa's philosophy.
Inspired by the carbonized firewood that symbolizes the Oharame culture of Yase, Tanjō embodies purification and quiet strength. Every element - from the sauna room and cold bath to the walls themselves - incorporates charcoal. This not only purifies and deodorizes the water, but also enriches it with minerals, creating steam and water that feel soft and gentle against the skin.
Among the three saunas, Tanjō is the only one where you can enjoy rotenburo-style open-air cooling between sessions.
The entrance design pays homage to Japanese tradition, blending the Way of Sauna (Sadō) with the Way of Tea (Sadō). Its low doorway, reminiscent of a tea room's nijiriguchi, invites you to bow slightly as you enter - an act that calms the spirit and signals the beginning of a truly meditative sauna experience.

Hijō - The quintessential sauna experience
The most popular among sauna enthusiasts, Hijō is the classic sauna experience.
Inspired by Japanese cypress (hinoki) - a sacred wood long revered in both Buddhism and Shinto, and grown on the slopes of Mount Hiei - Hijō envelops you in its refreshing fragrance and gentle warmth. The soothing aroma and penetrating heat help stimulate circulation and ease fatigue, leaving both body and mind renewed.
Its low ceiling intensifies the heat, while the natural breath of the hinoki wood maintains just the right level of humidity. This exquisite balance of temperature and moisture has earned Hijō high praise from guests who enjoy comparing the three sauna rooms, often calling it "the perfect equilibrium."

Bijō - The beauty mist sauna
A mist sauna designed for women, Bijō creates an atmosphere devoted to beauty and relaxation.
Soft pink "collagen lights" fill the room, reaching deep into the dermal layers to stimulate fibroblasts and promote collagen production. This gentle yet effective environment helps improve dry skin and enhances radiance and skin clarity, embodying a space thoughtfully created for women.
The sauna is constantly enveloped in a soothing mist, minimizing stress on hair and skin. Set at a comfortable low temperature of approximately 45°C, it is ideal for beginners and women seeking a gentle sauna experience. Even seasoned sauna enthusiasts praise Bijō for its relaxing warmth that can be enjoyed for extended periods.
