A simple alkaline thermal water supplied from Gero Onsen's Koda pump station. The alkalinity gives the slippery, soft-on-the-skin feel that places it in Japan's beauty-water family, and a generous load of metasilicic acid reinforces it, leaving skin noticeably smoother after a soak. Dissolved solids are light, so the water is gentle on the body and suits a long, unhurried bath rather than a short hot plunge. The posted analysis lists the spring-type indications for this water as autonomic nervous system instability, insomnia and depressed mood.
