| Several science-fiction writers, such as Aritsune TOYOTA, have made an interpretation of this story; Urashima Taro was caught by aliens, and brought to Ryugu-jo Castle (other planet) on the back of a turtle (spacecraft) at the velocity of light, therefore time passed in a different way to that on earth. |
複数のSF作家（豊田有恒など）がこの話を浦島太郎が宇宙人に攫われ、亀（宇宙船）に乗って、竜宮城（異星）へ光速移動したために地球との時間の進み方にずれが生じたとする解釈を提示している。 |
