Japan’s Policy on the Trans-Pacific Partnership (TPP) in Light of IR Theory and Analytical Eclecticism

Japan's policy toward the Trans-Pacific Partnership (TPP) Agreement has been controversial at the political, academic, and public levels. The domestic debate on the TPP literally split public opinion in Japan, and academic analyses are apt to be argumentatively divided into pros and cons. Likewise, earlier studies regarding the TPP in the field of international relations offered particular theoretical perspectives, yet tended not to conduct eclectic theoretical examination. In order to overcome the research gap, this paper attempts to provide both narrative and theoretical explanations by applying international relations (IR) theory in combination with "analytical eclecticism" as a research method in the field of global and international studies. As an application of IR theory and analytical eclecticism, this paper seeks to offer multiple theoretical perspectives and analysis on why Japan has supported and facilitated the TPP even after the withdrawal of the United States during the Trump administration.
