The fifty-third session of the Japanese Politics Online Seminar Series (JPOSS) took place on February 27, 2025. Saori Katada (University of Southern California) chaired the seminar and moderated the Q&A session.
Masanori Kikuchi (Washington University in St. Louis) presented a paper that examines the multi-generational effect of exposure to large-scale atrocities, specifically the atomic bombings of Hiroshima and Nagasaki, on attitudes toward war and foreign policy. Building on existing research that presents competing findings on the effect of large-scale violence on victims’ support for aggressive policies, Kikuchi utilizes the unique case of the catastrophic bombings and the strikingly dovish leanings of victims in Japan to study different channels of influence that may explain this outcome. He tests theories of familial and community pathways of transmission using a survey that compares current residents in Nagasaki, Hiroshima, and other regions in Japan. Kikuchi finds evidence for a correlation between community ties— current residents and public school attendants—and lower support for nuclear weapons possession as well as higher support for international cooperation.
James Dongjin Kim (University of Washington) and Atsushi Yamagishi (Hitotsubashi University) offered insightful suggestions on ways to sharpen the theory and possible biases in measurement. During the Q&A session, participants furthered discussions on sampling considerations, local boards of education, and alternative explanations for the causal pathway.
The organizers would like to thank the presenters, discussants, and participants, as well as the staff at the Harvard Program on U.S.-Japan Relations, who provided administrative support. We look forward to seeing you at the next session of JPOSS: https://jposs.org/.
