Winter is a great time to visit the Enoshima Island Spa. While it may be hard to imagine using an outdoor pool in winter, using a Japanese rotenbo (open air bath) is a very popular activity during winter in Japan. At Enospa the rotenbo overlooks the ocean so that you can relax in your bathing suit with your family and friends, in warmth of the pool, and enjoy the cool air on your face while taking in a lovely view.
