What explains Japan’s security policy change in recent decades? Heeding the ‘emotional turn’ in International Relations, this article applies a resentment-based framework, which defines resentment as a long-lasting form of anger and the product of status dissatisfaction. Leveraging interviews with 18 conservative Japanese lawmakers and senior officials, the article discusses the role, function, and prevalence of resentment in the remaking of Japan’s security policy, premised on constitutional revision. The analysis reveals that conservative elites are acutely status-conscious; and that those who blame a perceived inferior status on Japan’s alleged pacifism are more likely to see revision of Article 9 as an end in itself. For a subset of conservatives, however, the goal is rather to stretch the Constitution to enhance Japan’s means of deterrence vis-à-vis objects of fear or in solidarity with allies. Overall, the article demonstrates that resentment provides a fruitful lens for analyzing status dissatisfaction in international politics.
