Sodium chloride water piped to Jigokubaru along Beppu City's Kannawa supply line and sampled at the storage tank rather than at the wellhead. It is weakly acidic, colorless and clear, faintly salty, and moderately mineralized at about 4.0 g/kg of dissolved solids. Even at the tank it arrives among Japan's hottest supplied waters, and it carries 515 mg/kg of metasilicic acid, a silica load high enough to leave a thin moisturizing film on the skin and to place it in Japan's beauty-water family.
