A soak in the warm waters is a dip into traditional Japanese culture, and offers relaxation for body and soul. Head into the mountains of central Japan, or down south to the island of Kyushu and relax in rocky baths overlooking the ocean or in high-class mountain retreats.
You don't have to head too far out of the city to find relaxation. Hotels in Japan's major cities often come equipped with expansive spas offering relaxation therapy overlooking the cityscape. If you are on a slightly stricter budget, head to one of the many immaculate gardens—such as Shinjuku Gyoen in the heart of Tokyo or Kenrokuen in Kanazawa—to wander around the grounds built for the very purpose of relaxation. Be sure to schedule in some me-time during your trip to Japan.
