Nijo Onsen (Kirara no Yu), in Itoshima, Fukuoka, offers sodium-chloride water heated to 41°C. An indoor bath, an outdoor rotenburo and a sauna round out the bathhouse.
Insider tip — Kirara no Yu, the glittering spring, serves Itoshima City — western Fukuoka's most fashionable coastal district famous for artisan cheese factories, beach cafes, and the twin torii gates of Sakurai Shrine rising directly from the Genkai Sea. The Nijo valley spring draws from sedimentary aquifers between the Raikasan highland and the coast, where Itoshima's creative community of potters, winemakers, and textile artists has settled in the renovated farmhouses of this exceptionally scenic peninsula.
