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.

Is Japan on a path towards assuming a greater military role internationally, or has the recent military normalisation ground to a halt since the premiership of Junichiro Koizumi? In this book, Christopher W. Hughes assesses developments in defence expenditure, civil–military relations, domestic and international military–industrial complexes, Japan’s procurement of regional and global power-projection capabilities, the expansion of US–Japan cooperation, and attitudes towards nuclear weapons, constitutional revision and the use of military force. In all of these areas, dynamic and long-term changes outweigh Japan’s short-term political logjam over security policy. Hughes argues that many post-war constraints on Japan’s military role are still eroding, and that Tokyo is moving towards a more assertive military role and strengthened US–Japan cooperation. Japan’s remilitarisation will boost its international security role and the dominance of the US–Japan alliance in regional and global security affairs, but will need to be carefully managed if it is not to become a source of destabilising tensions.

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.
