Onsenmura No. 114
Analysis VerifiedOnsenmura No. 114, a chloride spring drawn from approximately 100 meters underground at Miyanoshita Onsen—one of Hakone's renowned Seven Hot Springs—carries a rich history. This area flourished as a therapeutic hot spring resort since the Edo period, evolving into an international destination during the Meiji era. The spring's unique feature is its gentle embrace, forming a 'salt veil' on the skin that slowly warms the body from its core. The restorative warmth lingers long after your bath, promoting deep relaxation for both mind and body. It is highly recommended for those seeking to soothe daily fatigue while immersing themselves in history.
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.
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.

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.
Known as "warming springs," sodium chloride springs offer excellent heat retention. After bathing, salt on the skin prevents sweat from evaporating, helping you stay warm longer. Avoid prolonged soaking; instead, try "split bathing" by alternating between soaking and resting.
With 510 mg/kg of chloride ions creating a warming veil on the skin, this spring offers lasting restorative warmth. The synergy of its pH 8.1 alkalinity and 107 mg/kg of metasilicic acid also promotes silky skin. It is perfect for deep relaxation and rejuvenation, soothing away daily fatigue.
While beneficial for cuts and dry skin, bathing should be avoided by those with general contraindications such as active tuberculosis or severe heart conditions. Please be mindful of bathing methods and duration.
