This article seeks to add to the existing literature on Japan`s peacebuilding by examining its involvement in the psychosocial reconstruction of children in conflict-affected 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.
