Gaga Onsen Gensen
Analysis UnverifiedThe Gaga Onsen source gushes naturally from the Nigorigawa gorge on the eastern flank of the Zao range, and its name is said to come from the craggy, towering cliffs that line the valley. Long treasured as a spring for the stomach and intestines, its clear, gentle water glides softly over the skin when you steep in it. It suits travelers who seek quiet time with the water deep in a mountain gorge to restore body and mind.
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.

▸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 reaches 58.3°C, so check the bath temperature and pour water over yourself before entering. Being a mild, neutral spring, it rewards an unhurried 10 to 15 minute soak in a cooler tub, leaving the skin feeling smooth.
With 395.2 mg/kg of bicarbonate and 187.5 mg/kg of metasilicic acid, this water gently softens the outer layer of the skin and is traditionally associated with silky skin. Its 275.0 mg/kg of sulfate may also help relieve pain from everyday stiffness and fatigue.
Avoid bathing during acute illness or with serious heart or lung conditions. The source reaches 58.3°C, so check the water temperature before entering.
