An alkaline simple thermal spring fed from Gero Onsen's Koda pump station. At pH 9.4 the water is alkaline enough to feel slippery and soap-like on the skin, placing it squarely in Japan's beauty-water family, while its light mineralization — 353.9 mg/kg of dissolved solids — keeps it gentle and undemanding on the body. Metasilicic acid at 66.7 mg/kg leaves the kind of thin silica film that makes skin feel noticeably smoother afterwards. The posted analysis names autonomic nervous system instability, insomnia and depressed mood as the spring-type-specific indications, which marks this as water for a long, unhurried soak.
