The Kirishima hot-spring area, spread across the volcanic slopes at the foot of the Kirishima mountains, is one of southern Kyushu’s finest onsen destinations. Fed by the region’s intense volcanic activity, the springs here are abundant and varied, including prized cloudy, milky-white sulphur waters that are rich in minerals and wonderfully soothing. Ryokan, hotels and public baths are dotted through the forested highlands and gorges, many with open-air baths (rotenburo) where you can soak in the hot mineral waters surrounded by mountain scenery, greenery and, in places, the sounds of a river or waterfall. After hiking the volcanic peaks or visiting Kirishima Jingū shrine, a soak in the sulphurous springs is the perfect way to relax, and staying overnight lets you enjoy the mountain onsen atmosphere and local cuisine. Scenic and restorative, Kirishima Onsen is a highlight of a southern Kyushu trip.
