A simple thermal spring blending two wells (Ami No. 221 and Yukawa No. 1), served at a community bathhouse in Yukawa, Ito City. Weakly alkaline at pH 8.4, it feels soft on the skin and sits in the Japanese beauty-water family. It carries 58.8 mg/kg of metasilicic acid, which leaves a thin silica film for noticeably smoother skin, and is classified as a hot spring at 42.3 °C.
