This paper examines Japan's security policy after the September 11 terrorism, arguing that its response has been part of a larger process of redefining its security role in the Asia-Pacific region for the last decade. The passage of the 1992 Peacekeeping Law and the 1999 US-Japan security guidelines were an important part of the drastic changes. The paper also discusses the Japanese government's response to the September 11 terrorism, looking into the question of how the government sought to maintain a balance between military contributions to US-Japan security alliance and the restriction on the “threat and use of force” prescribed in the Constitution. Japan's recent pro-activeness toward Asia and entry into regional politics is also examined. The paper concludes by arguing that the combination of continued Japan's security relationship with the US and its strenuous efforts to enter Asian regional politics will be the first step toward real “normalcy” of Japan.
