Japan’s port city of Nagasaki held a solemn ceremony on Saturday to mark 80 years since the U.S. atomic bombing, observing a minute of silence at 11:02 a.m., the exact time the plutonium weapon exploded on 9 August 1945. Mayor Shiro Suzuki warned that mounting global tensions could trigger “a crisis of human survival” and urged governments to present a concrete path toward eliminating nuclear arms. Prime Minister Shigeru Ishiba pledged that Tokyo would lead international efforts toward a world free of nuclear weapons while upholding Japan’s three non-nuclear principles. Roughly 2,600 participants, including representatives from more than 90 countries—among them the United States, Russia and Israel—gathered in Peace Park for the milestone observance. The register of the dead was updated with 3,167 additional names, bringing the official toll to 201,942. Historians estimate about 27,000 people died instantly and some 70,000 by the end of 1945 after the 10,000-pound “Fat Man” bomb struck the city three days after Hiroshima. Survivor Hiroshi Nishioka, 93, delivered the “Pledge for Peace,” recounting the shattered glass and radiation sickness he witnessed as a 13-year-old student. With the number of recognized hibakusha falling below 100,000, U.N. Secretary-General António Guterres, in a message read at the event, called for urgent action to strengthen the global disarmament regime and prevent any future use of nuclear weapons. Commemorations included the first simultaneous ringing in eight decades of the twin bells at Urakami Cathedral, one of which was recently restored with donations from U.S. Catholics. Nagasaki invited all 157 diplomatic missions in Japan; G7 envoys returned after last year’s boycott, though China stayed away. Suzuki said the city would continue sharing its experience so that Nagasaki remains “the last place ever hit by a nuclear bomb.”
