Sukoyaka Onsen sits on Iki island, Nagasaki Prefecture. Its sodium-chloride water reaches 41°C, with an indoor bath, an outdoor rotenburo bath and a sauna.
Insider tip — Sukoyaka Onsen, the healthy vigorous spring, serves Iki Island between Kyushu and Korea, one of Japan most archaeologically rich islands identified in the 3rd-century Chinese chronicle Wei Zhi as the kingdom of Ichima. Iki has been a horse breeding centre since antiquity — the island ponies (Iki-uma) have been designated a Living National Monument — and the island's sake breweries produce distinctive island rice wine using the fresh limestone spring water that makes Iki sake uniquely clean.
