In this episode, Dr. Takeuchi-Demirci resituates Japan's place in the transnational history of prewar birth control movements through the life and activism of Ishimoto Shizue, known as the Margaret Sanger of Japan.  We discuss the relationship between Ishimoto and Sanger, the position of birth control within the prewar feminist movement, Sanger's controversial visit to Japan, and Ishimoto's postwar political activities.
