This paper argues that despite different endorsements in the idea of ​​Japan as a "normal country", two main discourses can be generalized: one stated that Japan should take on more responsibility in international order and security without changing its constitution, while another advocated quickly adopting the idea of ​​a constitution to transform Japan into a more complete and powerful state. Since the debates on amending the constitution are still unresolved, this paper focused on Japan's policies and behaviors in shouldering international responsibility. This paper argues that despite domestic and international restrictions, Japan achieves piecemeal success in terms of increasing engagement in international security, strengthening the alliance with the United States (US), and strengthening its national defense to a certain extent. This paper ultimately argues that these achievements will continue with the wishes of the international community, but the amendment of the constitution and the expansion of traditional force will be limited by both domestic and international pressures. Japan as a “normal country” According to Yang (2012), The idea of ​​Japan becoming a “normal country” originates from Ichiro Ozawa, who argued that there was a political reform initiative to maintain international order and peace with the end of the Cold War. Japan, as he stated, should have its own responsibility and role, as a "normal country", respected and understood by the international community. With regard to assuming international responsibility, especially in security issues, Japan should go beyond the limits set by the Constitution of Japan (also known as the Post-War Constitution or Peace Constitution), strengthen the Japan-United State... halfway paper ......rants are also concerns that Japan will think twice (Soeya et al., 2011). Therefore, it is believed that Japan is moving towards a “normal country” slowly but surely. Works Cited Soeya, Y. (2011).
