Fukuju Onsen is located in Kirishima, Kagoshima Prefecture, Japan, within an active volcanic zone. Its sulfurous thermal water runs particularly hot, around 43°C. An indoor bath, an outdoor rotenburo bath and a sauna round out the facility.
Insider tip — 'Fukuju Onsen' (福寿 — fortune and longevity) in the upper Makizono area of Kirishima, entering the volcanic zone of the Kirishima mountain chain. As elevation rises toward the active Shinmoedake, Nakadake, and Karakuni-dake peaks, the springs shift from sodium-chloride to the strongly sulfurous volcanic waters that define classic 'Kirishima Onsen.' The sulfurous smell and milky-white water here announce the true volcanic character of this extraordinary geothermal landscape.
