A simple sulfur spring carrying hydrogen sulfide, with a faint rotten-egg note and visible gas evolution at the source. Strongly alkaline at pH 9.6, it gives a pronounced slippery feel and sits in Japan's beauty-water family. With 58 mg/kg of metasilicic acid layered in, it leaves the skin feeling smooth.
