The 1945 atomic bombing of Nagasaki involved the "Fat Man" nuclear weapon. The mission originally targeted Kokura, but thick clouds and smoke from raids on nearby Yahata obscured the city, forcing the aircraft to proceed to the secondary target of Nagasaki. The use of nuclear weapons was intended to accelerate the end of World War II and avoid high American casualties expected from a land invasion of mainland Japan. The mission's target selection was managed by a Target Committee including figures such as General Leslie Groves and physicist David M. Dennison. The strike, occurring three days after the bombing of Hiroshima, contributed to the unconditional surrender of Imperial Japan on August 15, 1945.

During the 81st anniversary of the bombing in 2026, Nagasaki Mayor Shiro Suzuki issued a peace declaration explicitly identifying United States military aircraft as the source of the attack. Suzuki described nuclear weapons as an "absolute evil" and called for Japan to uphold the Three Non-Nuclear Principles, transition toward security policies that do not rely on nuclear deterrence, and participate in the UN review conference of the Treaty on the Prohibition of Nuclear Weapons.

Japanese Prime Minister Sanae Takaichi, who reaffirmed Japan's adherence to the Three Non-Nuclear Principles, did not mention the United States as the responsible nation in her address. This omission drew criticism from the Russian Foreign Ministry, which suggested the administration's stance treated the event as if the bombs had fallen without a perpetrator. Following the ceremony, survivors (hibakusha) expressed disappointment with Takaichi, noting that her meetings with survivor organizations lacked concrete policy commitments or specific answers regarding support for victims.
