Postclassical realism and Japanese security policy

Abstract

The recent domestic constructivist studies characterize Japanese security policy as a serious anomaly to realism and a crucial case vindicating their approach to the larger study of world politics. The present paper challenges this view. It advances a postclassical realist interpretation of Japan's core security policy in the past quarter century. Japan's military doctrine expressed in the 1976 National Defense Program Outline (NDPO) is consistent with postclassical realism's predictions, as opposed to neorealism's predictions, which focus on the dynamics of the regional security dilemma and the question of financial burden resulting from military build-up. In addition, postclassical realism offers a more compelling theoretical guide for understanding Japan's core security policy than defensive realism or mercantile realism. This paper backs up its argument with the empirical evidence that Takuya Kubo, the author of the NDPO, himself intentionally based the NDPO on a postclassical realist line of thinking.
