Gaiatsu and Japan's Foreign Aid: Rethinking theReactive-Proactive Debate

Abstract

This article examines the role of the United States in Japan's foreign aid policy. The Japanese government often alters its course of action under U.S. pressure even if doing so would apparently undermine its own interests. Japan's unusual responsiveness to U.S. preferences appears counterintuitive given the fact that at least in the realm of foreign aid Japan's power clearly surpassed that of the United States. This article posits that Japan's responsiveness stems in large part from the asymmetry of interdependence between the two countries. After critically reviewing the existing literature, it conducts two case studies to examine the validity of the argument. The article concludes that the United States played a crucial role but Japan's responsiveness to American pressure reflects an act of will rather than a lack of coherent policy stemming from bureaucratic politics. The findings have important implications to the ongoing debate over whether Japan is a “reactive state.”
