#January Getaways 2026 Kurokawa Onsen, located in the Aso Mountains of Kumamoto Prefecture, Japan, is a well-known hot spring resort in Kyushu, renowned for its rich Japanese atmosphere and natural scenery. The hot spring town is surrounded by forests, and the ryokans (traditional Japanese inns) are mostly understated wooden buildings, blending naturally with the mountain scenery, creating a tranquil and healing atmosphere. The most unique feature here is the "Open-Air Bath Tour," where you can use a designated bathing glove to choose from several ryokans to experience different styles of open-air baths. Whether soaking in the hot springs, taking a walk, or enjoying the seasonal scenery, Kurokawa Onsen allows you to escape the hustle and bustle of the city and enjoy a pure and relaxing slow-paced travel experience.
