One day a young fisherman named Urashima Tarō is fishing when he notices a group of children torturing a small turtle. Tarō saves it and lets it to go back to the sea. The next day, a huge turtle approaches him and tells him that the small turtle he had saved is the daughter of the Emperor of the Sea, Ryūjin, who wants to see him to thank him. The turtle magically gives Tarō gills and brings him to the bottom of the sea, to the Palace of the Dragon God (Ryūgū-jō). There he meets the Emperor and the small turtle, who was now a lovely princess, Otohime. On each of the four sides of the palace it is a different season.
