The Japan-US security structure was built up under the situation of East-West Cold War and Japan's loss of self-defense capability after World War II. In its structure, the role of the US Forces stationed in Japan is “directly” to defend peace and stability in the Far East; while Japan's role is to provide the US Forces with bases free of charge and to support them by sharing expenses for the USFJ as well as to guarantee them freedom of actions. Thus, Japan “indirectly” contributes to the maintenance of international peace and security not only in the Far East but also in the world.The Japan-US security system functioned well as it was essentially designed to deter the then USSR threat in the region. Under such strategic environments, the Japan-US security system can militarily cope with the threats by means of Japan's “individual right of self-defense” and the “indirect supports” given to the USFJ mentioned above. However, with the end of Cold War the security environments have changed. During the Gulf War Japan could not carry out military action in that region. Japan's huge contributions based on the principle of “indirect supports” under the Japan-US security system were hardly appreciated. It even invited criticism at home and from abroad that Japan was playing a “check-book diplomacy.” Obviously the Japan-US security system malfunctioned.Nevertheless, for the US the security system with Japan is becoming increasingly important since the world's economic center was shifting from the West to the Pacific-Asia region and the US still feel the necessity of its military control over the region. Furthermore, most immediately there is the suspicion that North Korea might be developing nuclear-weapons and there is also the concern that Japan might eventually take an independent policy from the US. Indeed, there is also a worry that China might become a threat in the region in the future. At the same time, the US itself is facing the fiscal constraints to reduce its defense expenditures. Under these circumstances, it becomes logically the central US purpose to create a new Japan-US security system based on “collective defense” and “direct supports”.But the US military presense in the region that is a key element of the new “Definition” will be reduced and the US will gradually lose the military control in the region. On the other hand, Japan will grow into an independent strategic nation and China will become a real powerful state. For the stabilization of East Asia a new framework of multilateral security system is indispensable. Such framework will ensure the US's constructive commitments in the region, China's constructive participation, Korean Peninsula's stabilization and Japan's assuming the role of an independent political actor without provoking the suspicion of the neighboring nations. In the long run, Japan's security system will be based on the UN's global security system a regional security system closely connecting with it and Japan's own exclusively defense-oriented defense system. One can forecast that the Japan-US security system will gradually change into a political, rather than military alliance.
