Awara Onsen Well No. 40Operated by · 株式会社ホテルゆらく
Sodium Chloride spring
A cold-mineral spring drawn at 24 °C from Awara Onsen's Well No. 40. The chemistry is sodium-chloride leaning but lightly mineralized at just 831 mg/kg, so it falls short of the curative-spring threshold and carries no formal spring-quality name; it qualifies as an onsen under Article 2 of the Hot Spring Law by virtue of its fluoride content. Weakly alkaline at pH 8.4 with a very faint hydrogen sulfide whiff at the wellhead, hypotonic, and heated for bathing.
