Iki Retreat by Onko Chishin is a traditional ryokan on Iki Island in Nagasaki Prefecture, roughly an hour by ferry from Fukuoka. Rooms look out over the Tsushima Strait and come with private open-air hot spring baths, and guests can also use a communal bath, garden, bar and shared lounge. Meals feature fresh local seafood. It suits travellers seeking a quiet, upscale onsen stay on a remote island, and reviewers rate the service and cleanliness highly. The trade-off is access: you must arrive by boat or plane, and staff speak little English, so plan ahead if you do not speak Japanese. Nightly rates start from $470.
