Japan's security policy: from a peace state to an international state

The paper argues that a significant change in Japanese post-Cold War security policy has occurred, as compared to its Cold War security policy. Instead of relying solely on power-based realist variables, this paper argues that a significant change is taking place because of the shift in Japan's security identity from a 'peace state' to an 'international state'. What this refers to is that Japan sees itself as playing a more active role in military-strategic affairs in the post-Cold War period due to the normative structure shift within Japan in relation to the practices and role(s) in the regional and international security environment. To show change in Japan's security identity and its resultant security behaviour, norms in three areas that define and shape its security policy are contrasted - Japan's definition of national security; its contribution, in military terms, to regional and international security affairs; and the level of agency (control) Japan has in its security policy. The international-state security identity is increasingly recognised by the members of Japan's security policy-making elite and is used to formulate Japan's security policy in the post-Cold War period. It is also gradually being accepted by the larger Japanese society and has become a permanent feature of Japan's security discourse.
