Sakura Onsen, in Nakatsu, Oita, offers sodium-chloride water at 41°C. An indoor bath, an outdoor rotenburo and a sauna are on offer at this northern Kyushu bathhouse.
Insider tip — Sakura Onsen serves Nakatsu City, home of Fukuzawa Yukichi whose face appears on the 10,000-yen banknote as the founder of Keio University and Japan most important Meiji-era intellectual. Nakatsu is also Japan undisputed capital of karaage deep-fried chicken where more specialty karaage restaurants per capita operate here than anywhere on earth, and the seaside Nakatsu Castle faces the waters of Nakatsu Bay in one of Kyushu most picturesque castle-and-sea compositions.
