A strongly acidic, sulfur-bearing spring at Zao Onsen: aluminium and sulfate lead the mineral profile, with a chloride edge alongside. The water is colorless and clear but tastes sharply astringent and carries an unmistakable rotten-egg note of H₂S — acidic enough to prickle on contact with the skin. A generous 223.1 mg/kg of metasilicic acid leaves a smoothing silica film once the sting fades. The house guide printed for guests warns bathers to remove all jewellery and metal before soaking, since this water corrodes and discolours metal.
