The Representation and Meaning of Expo 70 Trauma in Urasawa Naokis 20th Century Boys

In this article, I examine Urasawa Naokis 20th Century Boys (20-seiki shōnen) as a post-disaster manga. In 20th Century Boys, disasters are layered; there is both immediate disaster in the looming extinction of humankind following a bioterrorist attack and symbolic disaster in the form of trauma. Disaster manga, even while depicting the bleak conditions of an apocalypse, typically convey a hopeful and futureoriented message in which a new generation overcomes the circumstances bequeathed by the preceding generation to forge a new world. The older generation is thus irresponsible and mistaken—a generation of mistakes that brought about the apocalypse— and the younger generation a force for change naturally entrusted with the future. 20th Century Boys parts with this convention. Members of the older generation (the twentieth-century boys) are aware of their mistakes and strive to make amends for them, while the younger generation (the twenty-first-century boys) supports and encourages them. The apocalypse thus brings together rather than divides generations. In this respect, 20th Century Boys is a post-disaster manga, transcending the frame of traditional disaster manga depicting change through generational transition. It is also a manga strongly critical of the past, evincing trauma rather than nostalgia, as is evident in its grotesque and nightmarish depiction of the 1970 Japan World Exposition.
