Dake Onsen is one of Japan's few naturally acidic hot spring sources. The onsen source is located some 8 kilometers away from Dake Onsen town, meaning the hot spring water must be pulled from the source, travelling for around 40 minutes before it reaches the town. During this journey, the hot water becomes softer, making it gentle on the skin. Since the Dake Onsen's hot spring waters are acidic, it is recommended that visitors rinse in the shower after bathing in the town's onsen. This onsen town is also a popular spot for cherry blossom viewing. The cherry blossom tunnel at Sakura Hill in Dake Onsen – an onsen town located on the periphery of Mt. Adatara – comes into full bloom in mid-April. Visitors are greeted with fantastic views of cherry blossom against a backdrop of Mt Adatara still sprinkled white with the remainder of last winter’s snow.
