Geo-economic strategy – deploying economic instruments to secure foreign-policy aims and to project power – has long been a key element of statecraft. In recent years, it has acquired even greater salience given China’s growing antagonism with the United States and the willingness of both Beijing and Washington to wield economic power in their confrontation. This trend has particular significance for Japan given its often tense political relationship with China, which remains its largest trading partner. While Japan’s post-war geo-economic performance often failed to match its status as one of the world’s largest economies, more recently Tokyo has demonstrated increased geo-economic agency and effectiveness.

In this Adelphi book, Yuka Koshino and Robert Ward draw on multiple disciplines – including economics, political economy, foreign policy and security policy – and interviews with key policymakers to examine Japan’s geo-economic power in the context of great-power competition between the US and China. They examine Japan’s previous underperformance, how Tokyo’s understanding of geo-economics has evolved and, given constraints on its national power-projection, what actions Japan might feasibly take to become a more effective geo-economic actor. Their conclusions will be of direct interest not only for all those concerned with Japanese grand strategy and the Asia-Pacific, but also for those middle powers seeking to navigate great-power competition in the coming decades.

Strategic links between Japan and Europe during the Cold War were limited. During this period the IISS helped bridge the gap between the two, exposing its membership base to the international affairs of Asia and Japan and providing Japanese scholars, strategists and diplomats with a platform from which to amplify their voices in the West. Analyses by these experts often appeared in IISS publications, but the Institute also gained key insights through its well-established conferences and lecture series. These initiatives illuminated Japanese strategic thinking and perspectives on contemporary critical issues in Japan’s and Asia’s foreign, security and defence policy.

This Adelphi book, through its collection of earlier analysis, helps the reader to understand the evolution of Japanese strategic thought from the 1960s until today, and shines a light on the continuities and changes in this thinking. New, original analysis of the material seeks to identify areas where such thinking was prescient and remains relevant to the contemporary strategic environment, and other areas where predictions failed or assumptions were proved wrong. These new essays were also informed by interviews of Japanese senior scholars and diplomats who spent time with the IISS. This book seeks to frame, educate and guide strategic thinking on the most pressing issues of today, both in and outside Japan and Asia, and will be of great interest to analysts, practitioners and students of international affairs.
