Japan, the geopolitical lynchpin in the East Asian region, has developed a unique maritime security policy and interpretation of the law of the sea. Japanese Maritime Security and the Law of the Sea examines Japan’s domestic laws and its approach to international law.

Since the late 1990s, the Japan Coast Guard (JCG) has countered a myriad of 'outlaw' threats at sea including piracy, terrorism, the proliferation of Weapons of Mass Destruction (WMD) and the threat posed by 'rogue states'. Japan's innovative strategy has transformed maritime security governance in Southeast Asia and beyond.

In the twenty-first century, the Indo-Pacific, which spans from the western Pacific Ocean to the western Indian Ocean along the eastern coast of Africa, has emerged as a crucial geostrategic region for trade, investment, energy supplies, cooperation, and competition. It presents complex maritime security challenges and interlocking economic interests that require the development of an overarching multilateral security framework. This volume develops common approaches by focusing on geopolitical challenges, transnational security concerns, and multilateral institution-building and cooperation. The chapters, written by a cross-section of practitioners, diplomats, policymakers, and scholars from the three major powers discussed (United States, China, India) explain the opportunities and risks in the Indo-Pacific region and identify specific naval measures needed to enhance maritime security in the region. Maritime Security in the Indo-Pacific opens by introducing the Indo-Pacific and outlining the roles of China, India, and the United States in various maritime issues in the region. It then focuses on the security challenges presented by maritime disputes, naval engagement, legal issues, sea lanes of communication, energy transport, humanitarian assistance and disaster relief, as well as by nontraditional threats, such as piracy, terrorism, and weapons proliferation. It compares and contrasts the roles and perspectives of the key maritime powers, analyzing the need for multilateral cooperation to overcome the traditional and nontraditional challenges and security dilemma. This shows that, in spite of their different interests, capabilities, and priorities, Washington, Beijing and New Delhi can and do engage in cooperation to deal with transnational security challenges. Lastly, the book describes how to promote maritime cooperation by establishing or strengthening multilateral mechanisms and measures that would reduce the prospects for conflict in the Indo-Pacific region.

Exploring everything from contemporary challenges to ocean security this book offers detailed insights into the increasing activities of state and non-state actors at sea. Chapters revisit the United Nations Convention on the Law of the Sea (LOSC), highlighting how not all maritime security threats can be addressed by this, and further looking at the ways in which the LOSC may even hinder maritime security.

This is the first major English-language study to explore the broad and longstanding connections between Japan’s national security and the safety of its sea lanes. Tracing issues from pre-and post-1945 eras, the book explores how Japan’s concerns with sea lane protection have developed across such diverse fields as military strategy, diplomacy, trade policy, energy security, and law enforcement. Drawing upon case study material and primary research including interviews with officials and security analysts, the book presents a chronological analysis of Japan’s sea lane security. While Japan’s security policies have recently undergone relatively rapid change, a historical treatment of sea lane security issues reveals long-term continuity in security policymakers’ perceptions and responses regarding Japan's defence and foreign policy. Revealing a neglected but important aspect of Japan’s military and economic security, the book investigates why officials and analysts continue to portray the defence of Japan’s sea lanes as ‘a matter of life and death’.

Law of the Sea in East Asia selects the most prominent maritime legal issues that have emerged since the post-LOS Convention era for a detailed discussion and assessment. The current marine legal order in East Asia is based on the 1982 United Nations Convention on the Law of the Sea (LOS Convention) and accordingly coastal states in the region are obliged to cooperate amongst themselves to exercise their rights and perform their duties. Keyuan, a respected expert in the fields of international and Chinese law, explores issues concerning compliance with the law of the sea, territorial disputes and maritime boundary delimitation, fishery management, safety of navigation and maritime security, and neglected issues in the law of the sea. This is the first book to examine maritime laws in East Asia, and as such will appeal to academics of law and Asian studies, lawyers and policy makers.
