A Mountain Hot Spring Inn Where 1,400 Years of Healing Flow
Nestled in the mountains of Saijō City, Yunotani Onsen is a historic hot spring inn where natural cold mineral water, drawn 100% from a spring at the foot of Mt. Ishizuchi, is gently heated with firewood. This legendary hot spring, said to have been visited by Empress Saimei, offers a timeless healing experience with its sulfur aroma and floating mineral deposits, evoking the atmosphere of an ancient therapeutic retreat. The spacious baths are divided into three temperature zones, soothing fatigue, muscle pain, and stiffness with every soak. With its unpretentious and nostalgic charm, Yunotani Onsen provides a serene place of rest where weary travelers can relax both body and mind before continuing their journey.

It is a hot spring flowing directly from the source. The hot water is thick and makes your skin smooth.
The food is delicious and the interior has been renovated to give it a modern feel.
It’s a little more expensive, but it’s worth it.
There is only one single room, so early reservations are recommended.
