Fukuchi Onsen Kongo
Analysis UnverifiedBorn in Fukuji Onsen, nestled in the mountains of Okuhida, where multiple sources merge into one. This special blend embodies the blessings of a land long cherished for its therapeutic waters. The soft, near-neutral water with a pH of 7.16 gently envelops the skin, while the high 95°C source delivers warmth to your core. This onsen is for those seeking to escape the everyday hustle, deeply relax their mind and body, and cherish themselves in a tranquil moment.
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.
Absorbed through the skin to gently promote peripheral circulation.
The aroma typical of sulfur springs, with circulatory and antibacterial effects.

▸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 temperature is extremely high at 95°C, so it is diluted with water to a suitable temperature. With a gentle pH of 7.16, a long, slow soak will allow you to warm up from the core. After bathing, be sure to moisturize to prevent your skin from drying out.
This simple thermal spring, with its skin-friendly pH of 7.16, is gentle and can be enjoyed by anyone. The abundant metasilicic acid (136.4 mg/kg) is expected to promote skin metabolism, leading to silky skin. It offers deep relaxation, perfect for days when you want to heal from daily fatigue and refresh both mind and body.
Not for drinking. Avoid bathing if you have an acute illness, especially with a fever, or if you have a progressive condition such as severe heart disease or active tuberculosis.
