Fujikawaguchiko Town No. 2 and No. 3 Mixed Spring
Analysis UnverifiedFuji-Kawaguchiko Onsen grew in the Heisei era as the town drilled wells and piped water to lakeside inns. This blend of springs No. 2 and No. 3 looks gentle—clear, odorless and tasteless—yet carries 672.6 mg/kg sulfate and 287.1 mg/kg calcium, a gypsum-type water with 396.9 mg/kg chloride, suited to those who want a slow, warming soak facing Mount Fuji.
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.
- Chloride (salt)397 mg/kg
- Feel
- Tastes salty; the warmth lasts after you get out.
- Said to
- Salt is said to form a film on the skin that keeps in heat and moisture. Bathing indications include cuts, poor circulation and dry skin.
- Note
- May sting cuts. Strong salty water can tire you—avoid long soaks.
- Sulfate673 mg/kg
- Feel
- Your skin feels moist; the water may taste slightly bitter.
- Said to
- Said to retain heat well and help heal cuts. Bathing indications include cuts and dry skin.
- Note
- It warms you well—do not stay in too long.
Effects are general descriptions based on the Ministry of the Environment’s indications by spring type, not a guarantee.
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 emerges at only 27.3°C, so the baths are heated. The neutral water is gentle on skin—soak about 10 minutes at around 40°C, rest, and repeat. With its chloride content, let the sweat settle before dressing.
Sulfate (672.6 mg/kg) and calcium (287.1 mg/kg) form a gypsum-type profile that may help relieve pain in stiff muscles, while 396.9 mg/kg of chloride leaves a light film on the skin for restorative warmth that lingers after the bath.
The chloride content keeps the body warm after bathing—avoid overly long soaks and drink water regularly to prevent dizziness.
