Nagasaki commemorated the 80th anniversary of the U.S. atomic bombing on August 9, 2025, with a series of solemn ceremonies and calls for nuclear disarmament. The city marked the occasion with a moment of silence at 11:02 a.m., the exact time the bomb was dropped in 1945, and the restored twin bells of Urakami Cathedral rang together for the first time since the bombing. The attack killed an estimated 70,000 people by the end of 1945, with tens of thousands more suffering from radiation exposure in subsequent years. Nagasaki Mayor Shiro Suzuki delivered a peace declaration urging an immediate ceasefire in ongoing global conflicts and warned of an imminent existential crisis posed by nuclear weapons. Prime Minister Shigeru Ishiba attended the peace memorial ceremony, reaffirming Japan's commitment to a world without nuclear weapons and quoting Nagasaki atomic bomb survivor and physician Dr. Nagai Takashi. United Nations Secretary-General António Guterres also called for urgent global efforts toward nuclear disarmament. The ceremony was attended by representatives from G7 countries and ambassadors from conflict-affected nations, including Russia. Survivors expressed frustration that their calls for nuclear abolition have largely gone unheard, emphasizing the importance of passing their memories and the lessons of the atomic bombings to younger generations to prevent future nuclear war. The event also highlighted the restoration of a bell lost in the bombing, symbolizing peace and hope. The commemoration underscored Nagasaki's desire to remain the last city ever targeted by a nuclear weapon amid rising global nuclear tensions.
