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. [ABSTRACT FROM AUTHOR]

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.

The build-up of Japan's military apparatus in the 1990s and 2000s has been often regarded by security analysts as indicative of a departure from the country's Cold War strategic posture. Japan appears to be engaged in a process of militarisation that is eroding the foundations of its 'exclusively defence-oriented' policy. In the case of the archipelago's naval strategy, such assessments overlook the longstanding significance of a core feature of its defence policy, namely the surveillance of maritime crossroads delivering the wealth of the country. The paper reassesses the evolution of the Japanese strategy since the Cold War by examining the development of the Japanese Maritime Self-Defence Force's submarine force, one of the key components of the defensive shield for these crossroads. The paper argues that with the changes in the security environment of the 1990s, Japan already fielded a mature force with state-of-the-art submarines, and that the rise of a new naval competitor aiming at controlling key strategic points along Japan's sea lanes reconfirmed the critical importance of submarine operations to Japanese national security.

This paper sheds light on a relatively underexplored aspect of Japan’s recent security changes by examining the subnational level where the impact has been far-reaching. It focuses on Japan’s maritime frontier zone: the Yaeyama Islands located at the southwestern end of the Japanese archipelago and administered as part of Okinawa Prefecture. It argues that while Yaeyama militarization has been primarily a national response to China’s portrayed assertiveness in the East China Sea, it has also been facilitated by the strategic actions of local political elites, in cooperation with sympathetic extra-local forces. Political elites from two islands, Yonaguni and Ishigaki, have been motivated primarily by diverging material and ideational factors. Yonaguni elites have viewed militarization largely through the prism of “compensation politics.” Their counterparts in Ishigaki have been driven by more ideological objectives, seeking militarization for deterrence purposes and otherwise transforming the island into a rightist breeding ground in defence of Japanese territory. Yaeyama militarization has not only diminished enthusiasm for seeking autonomy and enhancing economic security through microregional cooperation, but has also enhanced local-level insecurities while creating and exacerbating divisions.

Since the early 1990s Japan's defense policy has been under incremental significant change, revealed mainly in the legislative field. This paper explores the extent to which Japan's defense policy is changing in military terms. Analysis of Japan's latest security posture in Iraq (2003-2006) brings to light changes in Japan's overall defense policy in terms of defense priorities and implementation. [ABSTRACT FROM AUTHOR]

Japan has shown three distinct strategic cultures since its emergence as a modern state in the 19th century: isolationist and non-military, militarist, and post-World War II strategic culture characterized by great reluctance to use military power abroad, even in collective self-defence. This article examines Japan's strategic culture and the potential for a fourth distinct strategic culture through the broader framework of security identity, arguing that this is evolving but has not changed as much as one might expect due to institutionalized antimilitarism and political support for the security practices it has engendered. Contemporary Japanese strategic culture can be understood through debates over recent Japanese security policy as well as actual changes in security practice. Domestic politics and a changing international environment are likely to lead Japan to a somewhat more active military role in the near term, but an analysis based on the dynamics of Japan's dominant security identity suggests that its strategic culture will continue to show a reluctance to use or develop military power beyond very limited scenarios, despite vocal efforts by some political actors to increase military activity abroad.

This article draws upon previously unavailable document materials to question views pointing to a degree of stagnation in Japanese maritime thinking. It similarly reviews claims about trends to compensate the decline of national military power with the build-up of projection capabilities. The article’s main argument is that Japanese seapower is not declining. The Japanese Navy is evolving to combine enhanced capabilities to retain sea control in the Sea of Japan and the East China Sea with extended operational reach and flexibility, including an expeditionary component to meet alliance and diplomatic commitments in East Asia and beyond its confines.

In recent years, there has been an increasingly vigorous debate by a wide range of participants over the past, present and future of Japanese security and the national defence policy. Ever since the end of the Cold War, international relations theorists have cast their gaze to Japan, and have been given to re-examining 'comprehensive security' with a particular eye for the meaning of 'security'. The 1990s were a particularly interesting time for this scholarly revisionism, while events of September 2001 have cast an entirely different spectre on the nature and expectations of Japanese security, both domestically and internationally. This article is particularly concerned with the developments in the 1990s as scholars sought to reassert the 'defence' component of the comprehensive security policy hitherto pursued by Japan. This re-examination has elevated former Japanese Defence Agency (JDA) bureaucrat Kubo Takuya as the key architect in crafting Japan's security policy. Tsuyoshi Kawasaki's contributions to the debate are especially interesting on this point. He rightly challenges the short-comings of the so-called 'domestic-constructivists', especially Berger and Katzenstein. However, in attempting to demolish their cases for 'selective biases' he then proceeds to selectively argue a similarly biased case in asserting the superiority of yet another derivation of the realist cause - 'postclassical realism'. His key premises are based on his interpretations of the architect of Japan's National Defence Program Outline, Kubo, and in doing so 'proves' the military aspect of Japan's security policy and its 'inherent superiority' as an explanatory framework. Equally, one can mount a case for the 'comprehensive security' proponents by citing the work and presence of the late Okita Saburo in his contributions to understanding post-war security policy. This article will demonstrate a similar argument to that of Kawasaki's based on an analogous analytical framework which grounds Japanese security consciousness in a deeper historical context. It is part of a larger project which seeks to give empirical substance to constructivist interpretations of Japanese security. [ABSTRACT FROM AUTHOR]

The article examines the defense policies of Japan in 2005 concerning the ballistic missile defense (BMD) program proposed by the U.S. Key issues discussed include the factors behind Japanese support for the BMD program and domestic concerns regarding the impact of the introduction of anti-missile systems on its national security.
