• After the war, while helping in the rice fields around the site, I heard from my father that a bomb had fallen there during the war.
• My aunt went to see the impact site after the bomb fell.
Shozo Kanazawa’s testimony established the land parcel containing the impact point and helped determine its coordinates. Ishikawa (石川満) was the person who suggested to Tomoo Noguchi that it might have been the Kanazawa family’s field. Kenichi Tan interviewed Kanazawa and passed the account to Asahi Shimbun reporter Komatsu (小松重則), who conducted further interviews. The resulting article appeared in the Ibaraki edition on September 20, 2019, under a headline asking whether the simulated atomic bomb had fallen in Isohara, Kitaibaraki, and tracing the testimony. It was the first report that the site might have been the Kanazawa family’s rice field beside a stream in the hills of Irioosawa, Isohara.
