Kita Shinagawa Onsen Tenjin Yu, in Shinagawa ward, Tokyo, offers sodium-chloride water at 41°C, with an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — In north Shinagawa, one of Tokyo's most historic districts where the old Tokaido highway's first post-station (Shinagawa-juku) served Edo-era travelers, Tenjin Yu draws dark sodium-chloride kuro-yu (black water) from deep marine sediments beneath the megalopolis; the dramatic black mineral water — rich in ancient organic compounds from prehistoric sea deposits — offers a genuinely surprising natural phenomenon in the heart of Japan's capital city.
