Background & Context

During World War II, the United States dropped an atomic bomb on Hiroshima on August 6, 1945, marking the first use of nuclear weapons in warfare. Three days later, Nagasaki was similarly bombed. These events precipitated the surrender of Japan and the end of the war. In the decades since, Hiroshima has held annual memorial ceremonies to honor victims, promote peace, and advocate nuclear disarmament globally. The Atomic Bomb Dome serves as a poignant symbol of resilience and the devastating human cost of nuclear warfare. Survivors, called hibakusha, play a critical role in educating the public on the catastrophic effects of nuclear weapons and urging their abolition.
