Hanamure Onsen is located in Kimotsuki, Kagoshima Prefecture. Its sodium-chloride thermal water emerges at 40°C. The facility includes an indoor bath, an outdoor bath (rotenburo) and a sauna.
Insider tip — 'Hanamure Onsen' in Kimotsuki-cho, the sprawling rural municipality of Kagoshima's Osumi Peninsula. Kimotsuki contains some of southern Kyushu's most pristine forests, home to wild Japanese macaque troops that descend to the valleys in winter. 'Hanamure' evokes scattered flowers across the forested hillsides. The volcanic geology of inner Osumi delivers consistent sodium-chloride springs warming communities that have few other public amenities.
