No trip to Japan is complete without a relaxing dip in an onsen. What is an onsen? Onsen are natural hot springs, fueled by volcanic activity, as well as the resort atmosphere that has emerged around many such springs.
Japan offers around 2,300 onsen to choose from, many of them included in ryokan (traditional inns). We’ve compiled a list of ten of the best onsen in Japan. No matter what region you’re traveling to, you’ll be able to unwind. Reaching the onsen is simple and affordable when you use Japan Railways and the Japan Rail Pass.
