Kajiki Onsen Center is set in Aira, Kagoshima prefecture, in southern Japan. Sulfurous water, with a pH of 6.5, reaches 44°C here between an indoor bath and a rotenburo, complemented by a sauna.
Insider tip — Kajiki Onsen Center sits in what was once Kajiki Town, now part of Aira City in Kagoshima. The powerful sulfurous spring from the active volcanic zone beneath the Kirishima mountains is prized by locals, and views of Sakurajima volcano from the outdoor rotenburo are extraordinary on clear days.
