This episode of The IR thinker explores the deepening strategic partnership between Japan and the Philippines with Dr Satoru Nagao, tracing the evolution from post-war reparations to a mature security and economic relationship in today’s Indo-Pacific. The conversation examines how Tokyo’s Free and Open Indo-Pacific vision is understood in Manila, why the Philippines is not part of the Quad, and whether Japan is doing enough on defence cooperation in the face of shared challenges such as North Korean missiles and Chinese assertiveness. 

We unpack the significance of the Reciprocal Access Agreement, Japan’s economic role and “new capitalism” in the Philippine context, the security implications of Japanese radar grants, and the dynamics of Japan–US–Philippines trilateral ties, before turning to what is often overlooked in this relationship and where future research on Japan–Philippines cooperation should be heading.

Satoru Nagao
