This article seeks to add to the existing literature on Japan’s peacebuilding by examining its involvement in the psychosocial reconstruction of children in conflictaffected regions. It demonstrates that to this end Japan has implemented creative, recreational activities, and, to a lesser extent, community-building strategies. This article argues that there are three important implications of Japan’s involvement in psychosocial reconstruction for its own foreign policy: (1) psychological reconstruction can enhance its non-military approach to peacebuilding; (2) this field can potentially be another area of expertise in its own peacebuilding policy; and (3) in so doing, Japan may be able to carve out a niche in the field of international peacebuilding. This article concludes by identifying some limitations that can be developed into areas for future research.
