In the summer of 2021, when the Olympic and Paralympic Games were held in Tokyo, the City of Hiroshima, in cooperation with the City of Nagasaki, held the Hiroshima-Nagasaki Atomic bomb Exhibition. The aim of the exhibition was to introduce the reality of the atomic bombings and initiatives for peace in order to foster public opinion toward the abolition of nuclear weapons and the realization of lasting peace in the world. The exhibition was held at three locations in the Tokyo metropolitan area: Hanno City, Saitama Prefecture; Bunkyo Ward, Tokyo; and Chiyoda Ward, Tokyo.
　At the venues in Hanno City and Bunkyo Ward, there were displays of articles that were owned by A-bomb victims, photo panels showing the reality of the atomic bombing and the current situation of nuclear weapons, pictures of the atomic bombing drawn by A-bomb survivors, and pictures of the atomic bombing drawn jointly by high school students and A-bomb survivors. At the venue in Chiyoda Ward, in addition to the display of photo panels, there was a reading corner with books about the atomic bombing, and a DVD screening corner.
　However, due to the spread of COVID-19 infection, related events such as A-bomb survivor talks that had been planned for each venue had to be postponed. In addition, for the Chiyoda Ward exhibition, the originally planned venue could not be used due to the need to secure a venue for vaccinations, so the content of the exhibition was reduced.
　Although it was necessary to make various changes to the events, they were attended by a large number of people, mainly local residents.
　In a questionnaire survey of visitors, the following valuable comments were made: "It was really tragic, and I thought that such a thing should never happen again," (teenage visitor); "I realized that the fact that we are living normally now is not a matter of course, and how lucky we are. It gave me an opportunity to think about life," (visitor in their 20s); "From the viewpoint of infection control, I can’t go to Hiroshima and Nagasaki easily, and it was valuable to see the A-bomb materials in person. This exhibition made me want to visit the local museum again when the pandemic is over," (visitor in their 40s). Period: July 18 (Sun) - September 5 (Sun) (44 days, excluding museum holidays)
