岡温泉 岡275号
Oka Onsen Well No. 275A sulfate hot spring drawn from Oka Onsen Well No. 275 in Ito City, Shizuoka. The wellhead is genuinely hot at 47.0 °C with a generous 141 L/min flow, and at pH 8.4 the water sits in the mildly alkaline beauty-water family — soft on the skin without being slippery. Sensory profile is the boring-in-a-good-way trio of colorless, tasteless, and odorless, and the panel lists neuralgia, muscle pain, and joint pain among the approved bathing indications.
