 note = {pdf, There seem to have been several rules untouched in the story in terms of picturing the Urashima legend. Focusing on these, Urashima's clothes of the time when he returned from Ryûgû is one of them. In most picture scrolls Urashima is dressed in eboshi-kariginu, which is usually yellowish brown with some exceptions of which being yellow green. In my opinion, there might have been the rules among painters or the consensus about the image of visitors from a different world.
There are cases misunderstanding itself expands the pictures. Some of the picture scrolls of Urashima in the early modem times contain the scene that okina-ôna(an old couple), a woman and Urashima are sitting facing each other. The scene is set between the times he catches the turtle and he stays with Otohime at Ryûgû, but the story doesn't have the description matching the scene. It seems that it happened because the original scene that Ryuô and Otohime welcome Urashima was redrawn as if the scene is set in our real world. Also, in the picture of his journey to Ryûgû, a boy is rowing the boat which is originally supposed to have only a woman aboard. It can be also guessed that the boy Urashima was described as a man with sakayaki and, with a lag between pictures, the picture was redrawn as the one explained above.
The typical model of Urashima legend described from the early modern times to the modern times is Urashima Tarô riding a turtle, which already started in the early 18th centruy. It's often drawn in kusazôshi and nishikie. What is strange is Urashima riding the turtle standing on it. This may be because of making it look like “Bodhidharma crossing the Yangzi River on a reed”, and the turtle leading Urashima to Ryûgû is a minogame, which is regarded as sacred and appeared in the 17th century. The minogame was gradually turned into a normal turtle based on the idea of emphasizing the relationship with the sea as the meaning of minogame died out, but you can still find the turtle with a reedy tail in the present illustrated books.
As you see, the style of Urashima legend described in the pictures had been changing through the years. The pictures change by themselves apart from the main story and it seems that they sometimes caused the story to change.},
