Deconstructing the ‘Yoshida Doctrine’

Abstract

AbstractThere is a consensus that the post-war Japanese foreign policy is based on the Yoshida Doctrine or Yoshida Line, which refers to the strategies of former Prime Minister Shigeru Yoshida, who relied upon US military security, and maintained limited defense forces while focusing on economic recovery and growth. This paper reconsidered the Yoshida Doctrine, referencing multiple related arguments and evidence, reaching a conclusion that post-war Japanese foreign policy should not be called the Yoshida Doctrine or Yoshida Line. The Yoshida Doctrine is an analytical concept created by researchers in the 1980s to justify Japanese foreign policy. This was done in response to the domestic and foreign criticism of low-level military spending, despite the flourishing economy. The Yoshida Doctrine differs from other foreign policy doctrines and has no merit for being called a doctrine. Furthermore, the ideas supporting this doctrine are not based on definitive proof; rather, they merely represent Yoshida's image, and a spurious correlation, drawn between limited defense spending and high-economic growth. The analysis carried out in this study reveals that the Yoshida Doctrine is fundamentally flawed. As a result, this study insists that it is necessary to abandon the Yoshida Doctrine as a base for future research on Japanese diplomacy.
