Ei Beppu Onsen Center, also in Minamikyushu, Kagoshima, heats sodium-chloride water to 42°C. An indoor bath, an outdoor rotenburo bath and a sauna are on offer.
Insider tip — Ei Beppu Onsen Center takes the name Beppu from a local hamlet in Kagoshima Ei district — entirely separate from the famous Beppu in Oita, illustrating how beppu (別府, separate dwelling) was a common village name across dispersed agricultural Kyushu. The western Ei communities near Chiran are surrounded by Kagoshima's famous satsumaimo sweet potato fields and tea plantations that form the green and gold agricultural mosaic of this volcanic plateau.
