大涌谷温泉 蒸気造成混合泉3号線(強羅方面)
Owakudani Onsen Steam-Generated Blended Spring Line No. 3 (Gora direction)Mixed source
An acidic calcium sulfate-chloride spring generated from the volcanic steam of Owakudani. At pH 2.2 it is strongly acidic, sharp enough to prickle slightly on the skin, and the kind of water with a track record on stubborn skin conditions. The source emerges hot in the high-50s Celsius and carries 123 mg/kg of metasilicic acid.
- Ultra-acidic
