Tennen Kishu Kuroshio Onsen is located in Kainan, Wakayama Prefecture, facing the Kuroshio ocean current. Natural sodium-chloride water reaches 42°C, feeding an indoor bath, an outdoor rotenburo bath and a sauna.
Insider tip — Drawing on the legendary Kuroshio Current that sweeps warm Pacific water along the Kii Peninsula coast, this tennen (natural) spa captures the oceanic energy of one of the world's most powerful ocean currents in its sodium-chloride spring; the Kishu forest heritage and Kumano pilgrimage trails of Wakayama surround this coastal thermal tradition.
