Kumanojo Onsen, in Satsumasendai, Kagoshima, draws its sodium-chloride water from a spring at 42°C. An indoor bath, an outdoor rotenburo and a sauna make up the bathhouse.
Insider tip — Kumanojo Onsen, the bear castle spring, serves Satsumasendai City, the historic heart of the Satsuma Domain whose remarkable self-modernisation before the Meiji Restoration gave Japan the leadership class that dismantled the shogunate. The Irekata area of Satsumasendai preserves remnants of the domain's secret Western technology program where samurai studied foreign engineering through Dutch texts, preparing the industrial transformation that Japan world would launch in 1868.
