Japan’s Shifting Military Priorities: Counterbalancing China’s Rise

This article analyzes the most recent phase of Japan’s security policy reform, focusing on its shifting priorities towards the Japan Self-Defense Forces and the Japan–US alliance since mid-2010. From a realist perspective, it argues that these shifting military priorities first and foremost represent a traditional counterbalancing response to China’s rise. Conforming to the logic inherent in balance of threat theory, it moreover argues that this balancing behavior is explained by a confluence of two primary factors, namely Japanese perceptions of aggressive Chinese behavior in the maritime domain and concerns relating to the changing distribution of capabilities in China’s favor.
