Kannon Onsen No. 1 Spring
Analysis UnverifiedStruck in 1963, this spring takes its name from a seated Kannon statue said to have been unearthed during drilling. In the hills facing the Amagi range, its alkaline water feels remarkably slippery on the skin and is mild enough that it has long been enjoyed for drinking as well. It suits travelers who want to sink slowly into silky water amid mountain quiet.
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.
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 pH 9.4 the alkaline water softens the outer skin layer, giving a slippery feel. Go light on soap, rinse briefly with fresh water afterward and moisturize; the 48.6°C source keeps spots near the inlet hot.
With a pH of 9.4 and 143.9 mg/kg of metasilicic acid, this water is cherished for softening dull skin and may help leave it silky. As a gentle simple spring, it invites deep relaxation amid the mountain stillness.
Alkaline water readily removes skin oils, so those with dry skin should moisturize after bathing. People with general contraindications for hot-spring bathing should refrain.
