Oku-no-yu is an acidic sulfur-bearing sodium/calcium chloride spring (H₂S type). At pH 3.8 the water clouds milky white, with a tart edge and the unmistakable rotten-egg note of hydrogen sulfide. Generous metasilicic acid (94 mg/kg) layers in a faint silica softness behind the sharp, sulfurous bite.
