Bungo Onsen (Takada no Yu), also located in the city of Ōita, offers sodium-chloride water at 42°C in an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — Takada no Yu honours the Bungo tradition of hot spring culture — Bungo being the ancient province name for Oita (豊後, rich and fertile) synonymous with thermal bathing since the 8th century when imperial court records first documented these volcanic waters. The southern Ōita hills above this spring retain the citrus groves and rice terraces that still define the Bungo agricultural landscape.
