Hot (45.6 °C) simple thermal spring at Kamifunabara, with total dissolved solids of just 708 mg/kg keeping it inside the 'simple' classification despite a sulfate-dominant anion profile (about two-thirds of equivalent anions are SO₄). The wellhead pH of 7.4 sits squarely in neutral territory; the water reads as nearly colorless and clear, tasteless, with only a faint hydrogen-sulfide whisper. Lightly mineralized and gentle on the body, with a modest dose of metasilicic acid (37 mg/kg) softening the feel on the skin.
