SodiumChloruresBrome
Super Sento Shirahata, in the city of Chiba, Japan, offers sodium-chloride thermal water at 41°C. The facility combines an indoor bath, a sauna and a massage area.
Insider tip — Southern Chiba's neighborhoods face Tokyo Bay across the industrial waterfront that transformed this corner of the Kanto Plain after WWII. Shirahata Super Sento's dark artesian black water taps the deep Kanto basin aquifer — ancient Miocene marine sediments compressed into sodium-chloride brine far below the suburban surface. The JR Sotobo and Uchibo lines head south from here into the more scenic Chiba coast of sea cliffs, fishing ports, and whale-watching season at Choshi.
