The present article reviews the effects of wartime and post-war policies on regional agglomeration of landuse and transportation activities in Japan. For this purpose the authors have formulated a long-term model over the period 1920-85, and conducted its final test. After confirming the accuracy of the entire model, it is used to evaluate the wartime policies which caused excessive employment agglomeration in Tokyo, and post-war policies concerning the high speed Shinkansen rail network. We conclude that the choices of alternative policies would have led to a more balanced regional structure than there is now, with less agglomeration in both Tokyo and the Kanto region.
