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.

Sharing a similar geography at the opposite ends of the Eurasian Continent and dependent on maritime trade to supplement the lack of strategic resources, both the UK and Japan relied on the sea for their economic survival and independence as sovereign states. From the first alliance in 1902, through the World Wars, to the more recent operations in the Indian Ocean and Iraq, sea power has played a central role in the strategic calculus of both countries. This thought-provoking book, comprising contributions from a group of international scholars, explores the strategic meaning of being an island nation. It investigates how, across more than a century, sea power empowered - and continues to empower - both the UK and Japan with a defensive shield, an instrument of deterrence, and an enabling tool in expeditionary missions to implement courses of action to preserve national economic and security interests worldwide. Positioned within the comparative literature on Japan and the UK, the volume will have wide-ranging appeal including studies in Anglo-Japanese Relations, Naval Military History, and Studies in East Asian Defence and Sucurity, including Anglo-American and US-Japan strategic interests.

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’.

As tensions between China and Japan increase, including over the disputed islands in the East China Sea, Japan has adopted under Prime Minister Abe a new security posture. This involves, internally, adapting Japan’s constitutional position on defence and, externally, building stronger international relationships in the Asia-Pacific region and more widely. This book presents a comprehensive analysis of these developments. It shows how trust and co-operation with the United States, the only partner with which Japan has a formal alliance, is being rebuilt, discusses how other relationships, both on security and on wider issues, are being formed, in the region and with European countries and the EU, with the relationships with India and Australia being of particular importance, and concludes by assessing the likely impact on the region of Japan’s changing posture and new relationships.

While the US-Japan alliance has strengthened since the end of the Cold War, Japan has, almost unnoticed, been building security ties with other partners, in the process reducing the centrality of the US in Japan’s security. This book explains why this is happening. Japan pursued security isolationism during the Cold War, but the US was the exception. Japan hosted US bases and held joint military exercises even while shunning contacts with other militaries. Japan also made an exception to its weapons export ban to allow exports to the US. Yet, since the end of the Cold War, Japan’s security has undergone a quiet transformation, moving away from a singular focus on the US as its sole security partner. Tokyo has begun diversifying its security ties. This book traces and explains this diversification. The country has initiated security dialogues with Asian neighbors, assumed a leadership role in promoting regional multilateral security cooperation, and begun building bilateral security ties with a range of partners, from Australia and India to the European Union. Japan has even lifted its ban on weapons exports and co-development with non-US partners. This edited volume explores this trend of decreasing US centrality alongside the continued, and perhaps even growing, security (inter) dependence with the US. New Directions in Japan’s Security is an essential resource for scholars focused on Japan’s national security. It will also interest on a wider basis those wishing to understand why Japan is developing non-American directions in its security strategy.
