Expanding the Eyes: Japan and the Five Eyes Alliance

Issues & Insights Vol. 22, SR9, pp. 65-69


This contribution argues that Japan can offer the Five Eyes the use of its electronic surveillance capabilities, its vast intelligence infrastructure network, and its analysis and perspective on Asian politics. The Five Eyes would, in turn, be able to shore up capabilities that Japan is lacking, such as foreign intelligence and military defense. Despite Tokyo’s attempts at improvement, there remain significant issues with Japan’s complex and limited intelligence system, and its security clearance system. Moreover, clashes among the Five Eyes members (with or without Japan’s admittance) can potentially hinder trust and intelligence-sharing. With these unresolved issues, expectations from both Japan and the Five Eyes may be too high to consider outright admittance at this time.
