Yamanashi Fuefuki City
A long-established inn in Isawa Onsen with a natural onsen fed straight from its own source and proper saunas
Hanayagi no Sho Keizan is a long-established onsen inn in Fuefuki, Yamanashi Prefecture. Its pride is a natural onsen fed straight from its own abundant source, never recirculated. The alkaline simple spring is known as a “bath for beautiful skin” that helps the skin hold moisture, and you can soak in it to your heart’s content in the spacious main bathhouse, the rugged large rock open-air bath and the large hinoki open-air bath with its pleasant scent of wood. After working up a sweat in the dry sauna or the mist sauna, the cold plunge brings a crisp cool-down. There are also special rooms with their own open-air bath and a proper sauna, where you can spend blissful hours in private. Relaxation options such as beauty treatments and massage are plentiful too, deeply soothing the fatigue of everyday life.

The main bathhouse, where you can enjoy a natural onsen fed straight from its own abundant source, never recirculated. The alkaline simple spring is known for its soft feel and is loved as a “bath for beautiful skin” that leaves the skin smooth. In the spacious room you can give your whole body over to the fine water and relax.

A large open-air bath with two kinds to enjoy: a rugged rock bath and a hinoki bath with the warmth of wood. Natural onsen water from its own source overflows the tubs, and bathing while feeling the outdoor air is something special. Listening to the soothing sound of the water, you are restored in body and mind.

A private open-air bath in your room with views of the surrounding mountains. The natural onsen water comes 100% from the inn’s own source, fed straight in and never recirculated, with no water added and no reheating, and it is yours alone as often as you like, whenever you like. Free from anyone else’s eyes, it is a blissful space to enjoy fine water and quiet time to your heart’s content.

A dry sauna where you can really feel the heat. In a quiet space you can take your time working up a sweat and shed the fatigue of daily life. It is the perfect place to refresh a body already warmed by the onsen even more deeply.

A mist sauna that wraps you in soft vapor. It is gentle on the skin, and you can warm up slowly to the core without feeling short of breath. In this moisture-rich space you can enjoy deep relaxation.

A cold plunge where the cold pulls the body taut after the heat of the sauna. Fresh cold water wraps pleasantly around your skin and leaves you invigorated. It is an essential step for cooling down and refreshing yourself after the sauna.
