The fisher boy of Japanese folklore. He married a sea maiden and lived in a palace beneath the waves. When he was seized by the desire to see his parents again, his wife gave him a casket, which if unopened would ensure his safe return to the deep. Dismayed to learn that centuries had passed since he had left, Urashima opened the lid of the casket. At once a puff of white smoke rose from it and drifted away towards the sea, while he was shaken by a cold wind that turned him into an incredibly ancient man, then a corpse. Today the shrine of Urashima stands on the coast of Tango.
