A silky simple hot spring and spring-water cold plunge bath nestled in a mountain village
Okayama Tsuyama City
A day-use hot spring facility in the mountain village of Aba in Tsuyama, Okayama Prefecture. The alkaline simple hot spring drawn from deep underground contains radon and is known for its silky, smooth feel that gently wraps around the skin. There are two types of baths, a cypress bath and a rock bath, which alternate daily between men and women. The combination of the Finnish-style dry sauna and the outdoor cold plunge bath using the spring water as is is excellent, with the season's outdoor air and the spring's soft coolness in perfect harmony. The renovated relaxation space is also equipped with manga and hammocks, creating a place where you can surrender yourself to the slow pace of country life.
