Sudden onset natural disasters such as earthquakes are absolute physical and psychological levellers which spare no one from the event itself or the aftermath. The resulting physical devastation of a city and the psychological weakening of a population, however, also present opportunities. The opportunity to reorder society is unparalleled by any other historical event except perhaps war and with increasing regularity throughout much of the twentieth century, nation states have used disasters as a pretext to secure long held political goals. In September 1923, the devastation of Tokyo as a result of the Great Kantô Earthquake presented a significant opportunity to reorder Japanese society both on a physical and psychological level. In the post-disaster reconstruction period, the government was quick to capitalise on this catastrophe.
