The Japan Confederation of A- and H-Bomb Sufferers Organizations, or Nihon Hidankyo, was awarded the 2024 Nobel Peace Prize. The organization was formed in 1956, 11 years after the atomic bombs were dropped on Hiroshima and Nagasaki at the end of World War II. Gathering up groups of Hibakusha (atomic bomb survivors), their aim is to appeal to the Japanese government for relief and to ask for a world free of nuclear weapons. As the Norwegian Nobel Committee explains, the activities of Nihon Hidankyo and testimonies of the Hibakusha have helped build up the norm known as "the nuclear taboo." However, in the current global situation, it is said that the risk of nuclear weapons being used again is at its highest ever. As we trace the footsteps of Nihon Hidankyo and the Hibakusha, we remind ourselves of the messages carried by their stories.
