This project aims to examine the formation and dynamics of story-telling activities by atomic bomb survivors living in the U.S. There are survivors who experienced atomic bomb in Hiroshima or Nagasaki in August 1945 and migrated to the U.S. after the World War 2. Today, some of these survivors are involved with story-telling activities where they try to share with others their experiences of the suffering from atomic bomb. However, social situations surrounding these survivors are quite ambivalent. On the one hand, just as the U.S. government does, many people keep justifying the atomic bombing of Hiroshima and Nagasaki. On the other hand, some people such as anti-nuclear activists deny the justification and consider the sufferings of Hiroshima and Nagasaki as their reason to protest against nuclear arsenals. Living out their lives under those difficult situations, A-bomb survivorsin the U.S. have interacted with such socially and politically constructed discourses on A-bombing. This project will explore the interactions between A-bomb survivors, especially ones engaged in story-telling activities, and the socially created discourses on A-bomb in the U.S. In order to achieve this purpose, I will conduct fieldworks including collecting documents, interviews, and participant observations, focusing on the followings: (1) Discourses of the U.S. government and anti-nuclear disarmament movements on A-bomb dropping (2) Life histories of atomic bomb survivors living in the U.S. and history of their collective actions (3) History of story-telling activities by A-bomb survivors in the U.S. (4) The relationships between A-bomb survivors and story-telling activities By investigating the above, this project will examine social and personal factors by which atomic bomb survivors living in the U.S. become involved in sharing their experiences with others.
