Leprosy, Legal Mobilization, and the Public Sphere in Japan and South Korea

This article addresses the question of what gets transmitted in cross-national diffusion and why. It does so by analyzing the spread of rights-based activism from Japanese to South Korean leprosy (Hansen's disease) survivors in the 2000s. Previous scholarship would predict extensive diffusion of mobilizing frames and tactics, especially since Korean lawyers learned an effective legal mobilization template while working with Japanese lawyers to win compensation for Korean leprosy survivors mistreated by Japanese colonial authorities before 1945. Yet the form of subsequent activism by Korean leprosy survivors for redress from the Korean government differed from the original Japanese model. This case suggests the need for scope conditions on theories about isomorphism and the agency of brokers. In particular, it draws attention to how the structure of a country's public sphere—and especially its legal profession, news media, and activist sector—affects the feasibility of imported innovations related to activism and legal mobilization.
