Ginzan Onsen Cooperative Sources No. 2, 3 and 6 (Mixed)

銀山温泉 協組2号・3号・6号源泉(混合)
Flower-Flecked Waters of the Silver Valley

Ginzan Onsen is said to trace its origins to waters found by miners of the Nobesawa silver mine, which flourished in the Edo period, and the town still carries the mine's name. This blend of cooperative sources No. 2, 3 and 6 rises at 63.8°C, layering sodium and chloride with sulfate, and white mineral flakes drift softly through it. Rich in metaboric and metasilicic acid, it leaves the skin moist and the body warm long after bathing, suiting those who want to warm to the core in a riverside town lit by gas lamps on snowy nights.

BATHING TIPS
AI Generated

The source emerges at 63.8°C, so some baths can run hot. Pour water over yourself first, check the temperature, and take several short soaks; let sweat settle before dressing to keep the lasting warmth.

EFFECT STORY
AI Generated

With 786.3 mg/kg of chloride, traditionally said to leave a fine film on the skin, this water is known for restorative warmth that lingers after bathing. Its 327.9 mg/kg of sulfate may also help relieve pain on days of chill and stiffness.

CAUTIONS
AI Generated

Avoid bathing during acute illness or with serious heart, lung or kidney conditions. The source reaches 63.8°C, so check the bath temperature before entering.
