Japan and South Korea are Western-style democracies with open-market economies committed to the rule of law. They are also U.S. allies. Yet despite their shared interests, shared values, and geographic proximity, divergent national identities have driven a wedge between them. Drawing on decades of expertise, Brad Glosserman and Scott A. Snyder investigate the roots of this split and its ongoing threat to the region and the world. Glosserman and Snyder isolate competing notions of national identity as the main obstacle to a productive partnership between Japan and South Korea. Through public opinion data, interviews, and years of observation, they show how fundamentally incompatible, rapidly changing conceptions of national identity in Japan and South Korea—and not struggles over power or structural issues—have complicated territorial claims and international policy. Despite changes in the governments of both countries and concerted efforts by leading political figures to encourage U.S.–ROK–Japan security cooperation, the Japan–South Korea relationship continues to be hobbled by history and its deep imprint on ideas of national identity. This book recommends bold, policy-oriented prescriptions for overcoming problems in Japan–South Korea relations and facilitating trilateral cooperation among these three Northeast Asian allies, recognizing the power of the public on issues of foreign policy, international relations, and the prospects for peace in Asia.

For close to sixty years, the United States has maintained alliances with Japan and South Korea that have included a nuclear umbrella, guaranteeing their security as part of a strategy of extended deterrence. Yet questions about the credibility of deterrence commitments have always been an issue, especially when nuclear weapons are concerned. Would the United States truly be willing to use these weapons to defend an ally? In this book, Terence Roehrig provides a detailed and comprehensive look at the nuclear umbrella in northeast Asia in the broader context of deterrence theory and U.S. strategy. He examines the role of the nuclear umbrella in Japanese and South Korean defense planning and security calculations, including the likelihood that either will develop its own nuclear weapons. Roehrig argues that the nuclear umbrella is most important as a political signal demonstrating commitment to the defense of allies and as a tool to prevent further nuclear proliferation in the region. While the role of the nuclear umbrella is often discussed in military terms, this book provides an important glimpse into the political dimensions of the nuclear security guarantee. As the security environment in East Asia changes with the growth of North Korea's capabilities and China's military modernization, as well as Donald Trump's early pronouncements that cast doubt on traditional commitments to allies, the credibility and resolve of U.S. alliances will take on renewed importance for the region and the world.

The Burden of the Past reexamines the dispute over historical perception between Japan and South Korea, going beyond the descriptive emphasis of previous studies to clearly identify the many independent variables that have affected the situation. From the history textbook debates, to the Occupation-period exploitation of “comfort women,” to the Dokdo/Takeshima territory dispute and Yasukuni Shrine visits, Professor Kimura traces the rise and fall of popular, political, and international concerns underlying these complex and highly fraught issues. Utilizing Japanese and South Korean newspaper databases to review discussion of the two countries’ disputed historical perceptions from the end of World War II to the present, The Burden of the Past provides readers with the historical framework and the major players involved, offering much-needed clarity on such polarizing issues. By seeing behind the public discourse and political rhetoric, this book offers a firmer footing for a discussion and the steps toward resolution.

Examining the 160 year relationship between America and Japan, this cutting edge collection considers the evolution of the relationship of these two nations which straddle the Pacific, from the first encounters in the 19th century to major international shifts in a post 9/11 world. It examines the emergence of Japan in the wake of the 1905 Russo-Japanese War and the development of U.S. policies toward East Asia at the turn of the century. It goes on to study the impact of World War One in Asia, the Washington Treaty System, the issue of Immigration Issue and the deterioration of US-Japan relations in the 1930s as Japan invaded Manchuria. It also reflects on the Pacific War and the Occupation of Japan, and the country’s postwar Resurgence, democratization and economic recovery, as well as the maturing and the challenges facing the US Japan relationship as it progresses into the 21st century. This is a key read for those interested in the history of this important relationship as well as for scholars of diplomatic history and international relations.

The first in-depth study of the puzzling relationship between Japan and the Republic of Korea and the influence of the United States on it from the Cold War to the present. It draws on recently declassified U.S. documents, internal Korean government documents, and interviews with former policy makers in the United States, Japan, and Korea.

"This book does not argue for stronger security ties among the three countries based solely on a shared understanding of the threats posed by North Korea. Nor does it look toward containment of a rising China or resurgent Russia for its strategic rationale. Rather, the authors argue for broadening the foundation on which the three nations' ties rest. A better understanding of the complex weave of interests and values that binds the United States, South Korea, and Japan will stabilize the relationships and make them more resilient and adaptable to future developments."--BOOK JACKET.

The contributors to this book demonstrate empirically how Japanese public opinion is formed amid strained Japan–South Korea relations. Studying public opinion in Japan and South Korea is critically important for exploring the causes and consequences of the deterioration of the relationship between the two countries. Japan–South Korea relations are at their worst level since World War II. Faced with North Korea’s nuclear threat and China’s regional and global advances, Japan and South Korea are each allied with the US and function as key stabilizers within the Asia–Pacific "Pax Americana." These relations play a decisive role in East Asia’s international security. The contributors explore a variety of social scientific methodologies—both conventional quantitative surveys and experiments, as well as quantitative text analyses of published books and computational analyses of social media data—to disentangle the dynamic relationship between Japanese public opinion and Japan–South Korea relations. An invaluable resource for scholars of East Asian regional security issues.

A comprehensive look at the role of history, economics, security, threat perception, and domestic politics in the South Korea-United States alliance.

"Like all empires, Japan’s prewar empire encompassed diverse territories as well as a variety of political forms for governing such spaces. This book focuses on Japan’s Kwantung Leasehold and Railway Zone in China’s three northeastern provinces. The hybrid nature of the leasehold’s political status vis-à-vis the metropole, the presence of the semipublic and enormously powerful South Manchuria Railway Company, and the region’s vulnerability to inter-imperial rivalries, intra-imperial competition, and Chinese nationalism throughout the first decades of the twentieth century combined to give rise to a distinctive type of settler politics. Settlers sought inclusion within a broad Japanese imperial sphere while successfully utilizing the continental space as a site for political and social innovation. In this study, Emer O’Dwyer traces the history of Japan’s prewar Manchurian empire over four decades, mapping how South Manchuria—and especially its principal city, Dairen—was naturalized as a Japanese space and revealing how this process ultimately contributed to the success of the Japanese army’s early 1930s takeover of Manchuria. Simultaneously, Significant Soil demonstrates the conditional nature of popular support for Kwantung Army state-building in Manchukuo, highlighting the settlers’ determination that the Kwantung Leasehold and Railway Zone remain separate from the project of total empire."
