The men's bath, Tono no Yu, features lavish indoor baths accented with extremely rare ancient hinoki over 2,000 years old, while the women's bath, Hime no Yu, also uses high-quality hinoki in abundance. Certified as a Japan Onsen Association top-rated "five-star" property, these baths are filled with three fresh private hot spring sources, all 100% free-flowing with absolutely no added water or heating. Wrapped in the gentle scent of hinoki, guests can enjoy a truly exquisite bath while taking in the dynamic panorama of Mount Tanigawa spread across the large windows.

These two rustic open-air baths, the men's Sennnengan no Yu and the women's Gekkou no Yu, are directly connected from the indoor baths. The water is also smooth, fully free-flowing spring water from the source. With the slopes of Mount Tanigawa and the beautiful mountain range spreading out before you, you can linger over a long, relaxing soak while enjoying the clear blue sky and birdsong during the day, or the star-filled night sky and the cool breeze of Tanigawa at night, offering a luxurious sense of calm that makes you forget everyday life.
