Ikeryu Onsen Shichifuku is located in the Beppu Area, Oita Prefecture. This sulfurous spring heats the water to around 44°C, with an indoor bath, an outdoor rotenburo bath and a sauna.
Insider tip — Ikeryu Onsen Shichifuku sits in the volcanic Oita basin where seven traditional luck deities lend their name to this bathhouse drawing classic sulfurous spring water. Beppu is Japan's most prolific onsen region by volume, and this facility captures that steaming volcanic energy in concentrated form. The sulfur-heavy water is thought to benefit respiratory health and relieve chronic skin conditions. Go early morning before the steam thickens in the low-ceilinged indoor pools.
