Is Japan re-emerging as a normal, or even a great, military power in regional and global security affairs? This Adelphi Paper assesses the overall trajectory of Japan’s security policy over the last decade, and the impact of a changing Japanese military posture on the stability of East Asia. The paper examines Japan’s evolving security debate, set against the background of a shifting international environment and domestic policymaking system; the status of Japan’s national military capabilities and constitutional prohibitions; post-Cold War developments in the US Japan alliance; and Japan’s role in multilateral regional security dialogue, UN PKO, and US-led coalitions of the willing. It concludes that Japan is undoubtedly moving along the trajectory of becoming a more assertive military power, and that this trend has been accelerated post-9/11. Japan is unlikely, though, to channel its military power through greatly different frameworks than at present. Japan will opt for the enhanced, and probably inextricable, integration of its military capabilities into the US Japan alliance, rather than pursuing options for greater autonomy or multilateralism. Japan’s strengthened role as the defensive shield for the offensive sword of US power projection will only serve to bolster US military hegemony in East Asia and globally.

Japan is emerging as a more prominent global and regional military power, defying traditional categorisations of a minimalist contribution to the US-Japan alliance, maintaining anti-militarism, seeking an internationalist role, or carving out more strategic autonomy. Instead, this Element argues that Japan has fundamentally shifted its military posture over the last three decades and traversed into a new categorisation of a more capable military power and integrated US ally. This results from Japan's recognition of its fundamentally changing strategic environment that requires a new grand strategy and military doctrines. The shift is traced across the national security strategy components of Japan Self-Defence Forces' capabilities, US-Japan alliance integration, and international security cooperation. The Element argues that all these components are subordinated inevitably to the objectives of homeland security and re-strengthening the US-Japan alliance, and thus Japan's development as international security partner outside the ambit of the bilateral alliance remains stunted.

This book is an insider’s account of the problems facing the Self-Defense Forces (SDF), Japan’s postwar military, authored by the country’s leading submariner, Hideki Nakamura. Specializing in the submarine fleet, he became an ace commander, in addition to serving as an analyst and professor in security studies. During his career, he became increasingly troubled by the SDF’s ability to fight due to legal, political, and operational restrictions placed upon it. This book, a translation of his 2017 bestseller, is a must-read for those interested in Japan’s military and its ability to partner with other countries.

This work is a comprehensive analysis of the political and strategic relationship between Japan and China, each of which in important respects aspires to a global status commensurate with its economic and military might. These two great powers have to come to terms with a history of antagonism, each viewing the other as circumspectly as their small regional neighbors view them. Japan and Greater China reviews the domestic and international foundations of the foreign policies of the two countries, notably the politics of national identity. The strategic and economic underpinnings of the relationship are assessed not exclusively by reference to bilateral concerns but within the global and regional position and interests of the two powers.

Japan has been expanding its military roles in the post-Cold War period. This book analyses the shift in Japan’s security policy by examining the collective ideas of political parties and the effect of an international norm. Starting with the analysis of the collective ideas held by political parties, this book delves into factors overlooked in existing literature, including the effects of domestic and international norms, as well as how an international norm is localised when a conflicting domestic norm already exists. The argument held throughout is that these factors play a primary role in framing Japan's security policy. Overall, three security areas are studied: Japan’s arms trade ban policy, Japan’s participation in United Nations Peacekeeping Operations, and Japan’s enlarged military roles in international security. Close examination demonstrates that the weakening presence of the left since the mid-1990s and the localisation of an international norm encouraged Japan to broaden its military role. Providing a comprehensive picture of Japan’s evolving security policy, this book asserts that shifts have occurred in ways that do not violate the pacifist domestic norm. Japan's Evolving Security Policy will appeal to students and scholars of International Relations, Asian Politics, Asian Security Studies and Japanese Studies.

This comprehensive volume traces the evolution of Japanese military history—from 300 AD to present day foreign relations—and reveals how the country's cultural views of power, violence, and politics helped shape Japan's long and turbulent history of war. The legacy of Japanese warfare is steeped in honor, duty, and valor. Yet, some of the more violent episodes in this country's military history have tainted foreign attitudes toward Japan, oftentimes threatening the economic stability of the Pacific region. This book documents Japan's long and stormy history of war and military action, provides a thorough analysis of the social and political changes that have contributed to the evolution of Japan's foreign policy and security decisions, and reveals the truth behind the common myths and misconceptions of this nation's iconic war symbols and events, including samurais, warlords, and kamikaze attacks. Written by an author with military experience and insight into modern-day Japanese culture gained from living in Japan, A Military History of Japan: From the Age of the Samurai to the 21st Century examines how Japan's history of having warrior-based leaderships, imperialist governments, and dictators has shaped the country's concepts of war. It provides a complete military history of Japan—from the beginning of the Imperial institution to the post-Cold War era—in a single volume. This thoughtful resource also contains photos, maps, and a glossary of key Japanese terms to support learning.

This book offers a new explanation of military power, highlighting the role of uncertainty in the creation of combat capabilities.
