Short Abstract

This panel reexamines Japan's now-defunct Eugenic Protection Law (1948-1996), focusing on the meaning of "eugenics" under the law, the role of the Japan Association for Maternal Welfare in promoting sterilization policies, and the features of the subsequent redress movement.

Long Abstract

In 2018, Sato Yumi became first person to file a lawsuit against the Japanese government over forced sterilization carried out under the Eugenic Protection Law (1948-1996). Her case was followed by lawsuits brought by thirty-eight other victims across Japan. After initial defeats at the district courts, the litigation culminated in claimants’ victory, with the Supreme Court of Japan ruling the law as unconstitutional in 2024. These lawsuits attracted significant domestic and international media attention, prompting renewed historical inquiry into forced sterilizations and the publication of numerous scholarly and journalistic articles. Nevertheless, numerous important aspects of the law remain insufficiently examined.

This panel brings together three perspectives to reassess the Eugenic Protection Law.

The first paper reconsiders what “eugenics” meant under the 1948 law by analyzing Diet debates, legislative structure, and policy implementation. It argues that eugenics was gradually narrowed to a reproductive health framework, obscuring its ties with family planning and population policies.

The second paper focuses on the Japan Association for Maternal Welfare (JAMW), tracing its institutional trajectory and lobbying activities. The paper highlights the JAMW’s central role in promoting sterilization policies and shaping both “old” and “new” eugenics, an aspect that remains underexplored in existing scholarship.

The third paper examines the redress movement that emerged in 2018 and culminated in the plaintiffs’ victory in 2024. It analyzes the reasons why redress efforts emerged decades after the law’s abolition, as well as how media coverage, activist networks, and litigation strategies succeeded in holding the state responsible.

Together, these papers examine the conceptual, institutional, and political aspects of eugenics in postwar Japan.
