Outline of Research at the Start

This research seeks to clarify why, when, and how Japan engaged in diplomacy to solve conflicts that broke out in Southeast Asia during the Cold War. It also aims to explain the effectiveness of Japanese diplomacy, the international reactions to it, and how it changed over time. This research’s findings are expected to deepen the understanding of the features, limitations, and future potential of Japan’s role in this field and the impact on Japanese regional policy and image.

Outline of Final Research Achievements

By investigating and comparing four cases of Japanese diplomacy to resolve Cold War-era conflicts in Southeast Asia, this research has sought to clarify the motivations and characteristics of Japan’s role as a peace-broker. This study has found that geopolitical and economic factors, political leaders' interests, and the enhancement of Japan’s regional role were important factors behind Tokyo’s decision to engage in peacemaking. Considerations related to Japanese relations with the United States have, on some occasions, been part of the factors shaping the Japanese government’s decision to act for peace. As a peace-broker, Japan showed a tendency to adopt and inclusive and non-confrontational approach, often aiming at facilitating dialogue among the concerned parties. Behind-the-scenes diplomacy, publicly announced initiatives, and “economic incentives” are among the instruments used by the Japanese government to carry out its peace diplomacy.

Academic Significance and Societal Importance of the Research Achievements

This study fosters understanding of Japan’s postwar diplomacy and potential for playing a larger peacemaking role. It challenges views in the literature that Cold War era-Japan shied away from international political affairs, and shows that Japan’s role in Southeast Asia went beyond an economic one.
