Ureshino Onsen Wataya Bessou No.4 and No.5 Mixed Source
Analysis UnverifiedLegend says Empress Jingu, seeing a wounded white crane heal in the river, bathed her soldiers here and cried "how joyful" (ureshii), giving Ureshino its name; it later thrived as a post town on the Nagasaki Kaido. This pumped 68.8°C source is clear and, as a classic sodium bicarbonate spring, feels slick as soap—perfect for those seeking smooth, supple skin.
The bar length shows how abundant each component is compared to thresholds that make it "distinctive" (therapeutic spring standards, beauty spring criteria, etc.).
A trace component with gentle antibacterial and anti-inflammatory action.
Mild antibacterial action keeps the skin clean. Trace transdermal absorption supports tooth and bone health.
A natural moisturizer also used in skincare lotions. Forms a thin veil on the skin to reduce moisture loss after bathing.

▸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.
The source runs at 68.8°C, so check the tub temperature first. This weakly alkaline bicarbonate water lifts skin oils, so go light on soap, moisturize promptly after bathing, and let the chloride's lingering warmth cool slowly.
With 913.7 mg/kg of bicarbonate and 428.5 mg/kg of sodium gently lifting old skin cells, the water leaves silky skin, while 220.3 mg/kg of chloride seals in warmth for lasting relaxation.
The source is hot, so take care with temperature and avoid overlong soaks. The water strips skin oils, so those with dry skin should moisturize afterward.
