In Kumamoto, on the island of Kyushu, Kikunan Onsen Spa Resort Agannasse offers sodium-chloride water heated to 42°C. The facility includes an indoor bath, an outdoor rotenburo pool and a sauna.
Insider tip — Kikunan Onsen Spa Resort Agannasse serves the Kikunan district east of Kumamoto City, Japan second fastest-growing regional capital after Tokyo following its reconstruction from the devastating 2016 magnitude-7.3 earthquake. Kumamoto Castle, one of Japan three greatest castles, suffered catastrophic stone wall collapse in that earthquake and its extraordinary 20-year reconstruction programme has given the city a renewed sense of purpose around its most iconic landmark.
