Chapter Five: Japan's External Military Commitments

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.
