Insider tip — 'Hashima Onsen' at Hashima-shi Rojin Fukushi Center — an elderly welfare hot spring in Hashima city on the Nagara River, Gifu Prefecture. Hashima is famous for the Nagara River's centuries-old ukai (cormorant fishing) tradition, performed at night by torchlight, the cormorants diving to catch sweetfish (ayu) on command. The elderly welfare center's onsen serves Hashima's retired population with the alkaline thermal waters that have been drawn from the Nobi Plain's deep sedimentary aquifer — gentle, smooth waters appropriate for aging bodies.
