Insider tip — 'Fuku no Yu' (福の湯 — fortune spring) at Inasayama Onsen on the slopes of Inasayama (333 m) in Nagasaki — one of Japan's 'three great nightviews.' The Inasayama ropeway summit reveals Nagasaki's dramatic harbour — where Dutch East India Company traders at Dejima, Chinese merchants at Tojin Yashiki, and atomic bomb survivors all shaped world history. Soaking in these volcanic waters with Nagasaki's glittering bay spread below is an unforgettable experience.
