Insider tip — 'Senraku Onsen' (千楽 — thousand pleasures) at Ogase Tennen Yu in Hita city. Hita is one of Kyushu's most historically preserved cities — the Mameda-machi district retains an extraordinary Edo-period merchant townscape, with white-walled kura storehouses, wooden machiya shophouses, and summer ukai cormorant fishing on the Mikuma River. Soaking in a thousand pleasures of the Hita thermal spring before strolling the lantern-lit Mameda-machi is among Oita's most refined cultural experiences.
