Abstract

This study analyzes historical documents related to the regulatory reform of recombinant DNA technology in Japan, reflecting the origins of bioethics in the country. Accordingly, the study examines deliberations conducted by committees independently established across multiple ministries and traces how these ministry-level discussions shaped a gradual shift in national guidelines away from mandatory biological and physical containment. The findings indicate that, in the early 1980s, government bodies relaxed containment standards set out in earlier recombinant DNA guidelines by drawing on advances in risk-assessment research. Around the same time, the foreign affairs ministry convened an expert meeting that included bioethicists from advanced industrial nations. These discussions confirmed that recombinant DNA techniques posed minimal risk when used under appropriate controls, and the meeting’s statement recorded agreement on the need to establish ethical standards for research involving human subjects. However, participants refrained from promptly identifying specific principles related to individual dignity. In parallel, the ministry responsible for industrial policy participated in international deliberations that led to the establishment of a low-risk category, allowing existing facilities to be approved through case-by-case review—a framework that informed Japan’s subsequent regulatory reforms in the late 1980s.
