JAPAN’S ROLE IN THE QUAD: FROM INITIATOR TO ARCHITECT

Abstract

The article analyzes Japan’s role in the creation and evolution of the Quadrilateral Security Dialogue (QUAD) since 2004. Amid the intensification of U.S.–China rivalry, the QUAD has become one of the central minilateral formats in the Indo-Pacific region. In most existing studies, Japan is considered merely as one of the four participants in the grouping, while a systematic analysis of Japan’s strategic leadership throughout all phases of the format’s evolution remains incomplete.

The aim of the study is to reconstruct Japan’s role in each of the three phases of the QUAD’s development (1.0, 2.0, 3.0) and to substantiate the characterization of Japan as a strategic architect of the regional order.

The scientific significance of the study lies in clarifying the understanding of the capacities of middle powers in shaping regional security institutions. Its practical significance is related to the applicability of the findings to the analysis of Indo-Pacific strategies pursued by great and middle powers, as well as to forecasting the development of minilateral formats.

The methodological framework of the study includes case study analysis, the historical-genetic method and periodization, process tracing, comparative analysis, and content analysis of primary sources.

The main findings show that Japan has consistently performed qualitatively different yet interrelated functions within the QUAD: that of a conceptual initiator (2004-2008), a strategic architect using the instrument of “tactical hedging” (2012-2020), and a co-institutionalizer of an expanded non-military agenda (since 2021).

The value of the study lies in its synthesis of theoretical frameworks – realism and constructivism – as well as in its analysis of recent English-, Russian-, and Chinese-language publications.

The practical relevance of the study’s findings is determined by their potential use in preparing analytical and educational materials on security issues in the Indo-Pacific region and on the strategies of middle powers.
