Kobe Minato Onsen (No. 1 Well)
Analysis UnverifiedThis port-town spring is drawn from 1,150 m beneath the First Pier of Shinko, reclaimed land surrounded by the sea on three sides in Kobe Port. Bicarbonate, the soda component, blends with sea-born salt, smoothing the skin while keeping you warm long after bathing. Close to body temperature at 37°C when it emerges, it is a gentle, neutral, pale-yellow water.
The bar length shows how abundant each component is compared to thresholds that make it "distinctive" (therapeutic spring standards, beauty spring criteria, etc.).
A natural moisturizer also used in skincare lotions. Forms a thin veil on the skin to reduce moisture loss after bathing.
A trace component with gentle antibacterial and anti-inflammatory action.
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.
The source is a lukewarm 37°C, so check the temperature even in heated baths and enjoy longer, unhurried soaks when it is mild. Bicarbonate leaves skin clean, so moisturize afterward, and rinse only lightly to keep the warming chloride film.
With 596.5 mg/kg of bicarbonate softening the skin, the water leaves a silky skin feel, while 433.8 mg/kg of chloride forms a light salt film for restorative warmth that lingers.
Chloride springs keep warming you after bathing, so avoid long soaks and drink water often. Those in acute illness or with serious heart or respiratory conditions should refrain or consult a doctor, and avoid bathing after alcohol or meals.
