Japan’s Space Diplomacy in a World of Great Power Competition

This article probes Japan’s space diplomacy in a world returned to great power competition. Today, Japan’s space diplomacy manifests in a wide variety of contexts at the global, regional and bilateral levels. The principal argument is that the Japanese state is responding to gathering external threats through diplomacy that communicates, persuades and bargains in the country’s science, economic and military space interests. This proactive positioning allows Japan to situate its advanced technologies in the context of fierce economic competition, cultivate an image as a pacifist and responsible actor in the turbulent international order, and set pragmatic expectations about building peaceful prospects in outer space.
