A sodium and calcium chloride spring, salty and heat-retaining. With dissolved solids at roughly 16,270 mg/kg it is richly mineralized and leaves a mineral film on the skin — a hypertonic water with a distinctly salty edge at the source. Alkaline in reaction, it is drawn at a free-flowing borehole wellhead, accompanied by natural gas (mainly methane) rising with the water.

275. サンライフ焼津 黒潮温泉, Yaizu Public onsen. Costs 560. Listed hours 09:00–20:30, except Mon. They stamp the 60 Onsen of Shizuoka 24/25 booklet. Online photos match. Indoor and outdoor baths with clear water. Not a particularly interesting place — safe to skip.
