Abstract: This article argues that the creation of ‘strategic partnerships’ as an alternative form of alignment represents an effort by Tokyo, and other US-allies, to ‘decenter’ their respective security policies from their erstwhile over-dependence on Washington. By examining the nature, purpose, and dynamics of strategic partnerships more closely, and investigating the empirical case of Australia, we can gain a greater appreciation of their significance both to Japan’s evolving security policy and the broader role they play in the Asia Pacific security landscape. The article argues that Australia has been the most significant and successful of Japan’s new strategic partnerships to date, has therefore come to represent the template for other new alignments, and hence provides a yardstick against which their effectiveness can be measured. It concludes that while the strategic partnership certainly represents a new departure for Japanese security policy – ostensibly independent of the US-alliance – closer inspection reveals how this relationship remains fundamentally bound to the broader American-hub-and-spokes system.
