A sodium- and magnesium-led bicarbonate-chloride spring in Beppu — the jūsō-sen (soda-water) style, soft on the skin, with a salty edge layered in from the chloride sub-type. Mildly alkaline and moderately mineralized at 1,900 mg/kg, it comes out of the well very faintly yellow but clear, and both tasteless and odorless. What sets it apart is metasilicic acid at 201.2 mg/kg — enough silica to leave a thin moisturizing film, which places it squarely in Japan's beauty-water family.
