Looking to soak away your stress in a traditional Japanese onsen? Whether you’re a first-time visitor or a seasoned traveler, Japan’s hot springs offer one of the most serene and healing experiences in the world. From snowy mountain retreats to ocean-view baths, here’s your ultimate guide to the best onsen across Japan.
What Is an Onsen?
An onsen (温泉) is a natural hot spring bath, rich in minerals that offer therapeutic benefits. Japan has over 3,000 onsen towns, many with unique water properties believed to aid in muscle relaxation, skin care, circulation, and even detoxification.
