The 1995 Tokyo subway attack by the Japanese religious movement Aum Shinrikyō represents one of the most dramatic examples of violence by a religious movement in modern times. Initially urban-based but with a rural communal presence, Aum believed that it had a mission to transform the world and fight in an imminent apocalyptic war between good and evil, and it engaged in numerous conflicts with the secular world it despised. While emphasising the significance of religious visions in Aum's activities this article examines the degree to which Aum's associations with the city of Tokyo also featured as an element in its violence.
