The Jingu Onsen onsen, in Sapporo, Hokkaido, Japan, offers sodium-chloride water at 41°C in a setting combining an indoor bath, an outdoor bath and a sauna.
Insider tip — Jingu Onsen is a neighbourhood bathhouse near the Hokkaido Jingu shrine complex in Sapporo's Maruyama district, drawing deep sodium-chloride thermal water from the same Sapporo brine aquifer that feeds the city's celebrated dark-water onsen. The forested shrine precinct visible from the facility's upper floors creates an unusual blend of sacred landscape and urban bathing culture. Winter visits are magical when snow blankets the shrine gardens and the contrast between freezing air and the hot brine pools is at its most invigorating. A popular choice among Sapporo residents after shrine visits on New Year's Day.
