Analysis UnverifiedThis spring rises deep in the Azuma mountains at about 1,100 m, reached by a mountain road climbing beyond Shirabu Onsen from Yonezawa. Counted among Yonezawa's eight hot springs, it sits in a valley near the headwaters of the Mogami River, where bathers gaze at waterfalls and ridgelines from open-air pools. Rich in calcium, the water leaves white mineral flakes on the tub floor and feels soft and smooth, ideal for those who want to savor mountain scenery in secluded quiet.
The bar length shows how abundant each component is compared to thresholds that make it "distinctive" (therapeutic spring standards, beauty spring criteria, etc.).
Scores are calculated from mineral analysis data based on the Mineral Spring Analysis Guidelines (Ministry of Environment, Japan). They are unrelated to facility atmosphere or service quality.
▸Note
The temperature, pH and component values shown here are based on the hot spring analysis (source). Actual values in the bath may differ depending on heating, dilution, recycling and filtration. Please check current usage status at the facility.
At 50.7°C the source is hot and indoor baths can feel warm, so pour water over yourself first. White mineral deposits make floors slippery, and mountain nights are cold, so dry off and dress warmly soon after bathing.
With 755.4 mg/kg of sulfate and 280.2 mg/kg of calcium, this calcium-sulfate spring has long been valued for easing stiff muscles and joints and may help relieve pain. A slow soak in the 50.7°C water warms you to the core, offering restorative warmth that lingers even in the cool mountain air.
Avoid bathing during acute illness or with serious heart or kidney conditions. Mind the hot water, and watch your step on floors made slippery by mineral deposits.
