The Views of Prime Minister Hatoyama Yukio on Japan’s Foreign Policy Within the Context of the Search for a New Grand Strategy

At present, security environment in East Asia is becoming increasingly fraught, characterised by the growing strategic rivalry between the US and China. Meanwhile, Japan is faced with the challenge of formulating such a foreign policy approach that would both ensure its national security and avoid further escalating the US-China conflict. In these circumstances, it is of interest to examine the views of Japanese Prime Minister Hatoyama Yukio (2009–2010) on Japan’s foreign policy and its role in the international community. This article analyses Hatoyama’s attitudes and rhetoric within the context of Japanese political elites’ longstanding search for alternatives to the Yoshida Doctrine, which underpinned Japan’s grand strategy throughout the Cold War. While the Prime Minister’s attempts to modify Japanese diplomatic approach have often been considered incoherent or “naïve”, the author argues that, drawing partially from the concepts pertaining to Japan’s role on the international stage that were introduced in the 1990s, Hatoyama consistently advocated the formulation of a new strategy. While admitting that some of Hatoyama’s proposals were not well-thought-out and went beyond the political mainstream, the author posits that he pursued the same goal as previous Japanese leaders, namely achieving balance in Japan’s relations with the US and China. The parameters of Hatoyama’s strategy were different from both the Yoshida Doctrine and the emerging course towards a more robust security policy, which was fully implemented under the second administration of Abe Shinzo (2012–2020). This strategy was based on Japan’s proactive role in upholding global stability through non-military means, reducing its dependence on the US, deepening integration in East Asia, and achieving friendly ties with China. The objectives of this article are to analyse Hatoyama’s political philosophy, identify the similarities and differences between it and other key contemporary foreign policy initiatives, as well as examine the Prime Minister’s approach towards foreign-policy making. The sources include Hatoyama’s speeches and writings as well as a range of academic literature devoted to analysing his foreign policy with an emphasis on the works of Japanese scholars.
