Takamiya No. 2 Spring, the source serving Hotel Jurin at Zao Onsen, is a strongly acidic sulfur water: at pH 1.8 it is sharp enough to prickle on contact, and 16.8 mg/kg of free hydrogen sulfide carries the unmistakable rotten-egg note. Aluminium leads the cation side, with sulfate and chloride behind it and 2,587 mg/kg of dissolved solids giving the water real body. A generous 235.8 mg/kg of metasilicic acid still places it in Japan's beauty-water family, leaving a silica smoothness underneath the acid bite. The house notice asks bathers to remove glasses, rings and other metal items before entering, which is exactly what water this acidic demands.
