In July 1961, a film entitled Momotaro-taisen-Onimashima was released in Taiwan. While the picture was still showing, however, a rumor about it spread nationwide and seriously affected the public image of the hero. Eventually the rumor forced the film company to change not only the tone of advertisements in the newspapers but also even the title of the film itself. Such a transformation of the old story in a given social context should lead to another question, that is, how the same story was interpreted and reworked in postwar Japan.
