15 kinds of baths looking out toward Mount Tenzan: a mountain-valley resort where lukewarm natural onsen lets you lose track of time
Furuyu Onsen ONCRI is a mountain-valley resort for therapeutic onsen stays in Saga City, Saga Prefecture. Its natural onsen wells up from its own source at a generous 43 tons a day and is a renowned spring also known as the “beauty bath.” Soaking for a long time in its lukewarm water, which is gentle on the body, brings deep relaxation to body and mind. Part of the appeal is making your way around the many baths, from the open-air bath looking out toward Mount Tenzan to the reclining bath and the box steam bath. The main bathhouse also has a sauna and a cold plunge, so you can refresh yourself by alternating hot and cold surrounded by nature. The detached rooms each have their own bath, where you can enjoy a private soak in a stillness that seems to melt into the mountainside. There is also a restaurant making the most of seasonal local ingredients, so you can fully savor a modern take on the therapeutic onsen stay.

The main bathhouse draws on its own source, known for its generous flow.
