Misasa Onsen Mansuiro

Misasa Onsen Hot Springs were discovered 830 years ago, and are steeped in legend.
The name Misasa means three mornings, and comes from a legend which says if a sick person bathes in the hot spring for three days, on the third morning their sickness will be cured on.
Misasa Onsen Hot Springs contain one of the highest levels radon of any spa in the world. Radon has beneficial effects for rheumatic disease, gout, high-blood pressure, arteriosclerosis, diabetes, alimentary disease and diseases of the bile duct and tract.
The indoor spa is filled with radium steam rising from the bathtub. You will feel its relaxing effects throughout your body every time you inhale.

Private bath
“Shinjyu-no-yu”

Free-flowing spa
A big cypress bath with free-running hot spring from our private source, and room for about 10 people at a time.
Unlike our large bath, Shinju no Yu holds the steaming vapor inside the facility more tightly, so the unique Misasa Onsen inhaling effect is also more pronounced.
Take as much time as you want with your partner, family or friends in a famous, endlessly flowing hot spring at Misasa Onsen Hot Springs.
