HIROSHIMA, JAPAN / RankWire.AI / – Marking the 81st anniversary of the atomic bombing, Hiroshima once again called for global efforts towards nuclear disarmament. Mayor Kazumi Matsui presided over the annual Peace Memorial Ceremony held at Peace Memorial Park. Attendees, including survivors, relatives, officials from Japan, and international delegates, gathered near the Atomic Bomb Dome. At 8:15 a.m., a bell rang precisely at the moment the explosion occurred on August 6, 1945, after which the crowd observed a minute of silence to honor those who lost their lives.

Through the city’s Peace Declaration, Matsui urged national leaders to shift away from reliance on nuclear deterrence, emphasizing the human toll of atomic warfare and calling for nuclear-armed nations to confront these consequences. He further appealed for political figures to visit Hiroshima and Nagasaki to listen to hibakusha, the survivors whose testimonies have long been central to Hiroshima’s annual memorials. For decades, Hiroshima’s August 6 ceremony has served as a platform to advocate for nuclear abolition and to keep the memory of the bombing alive.
This year’s event was attended by roughly 50,000 individuals, including representatives from 121 countries and regions, as well as the European Union. Prime Minister Sanae Takaichi was present for the first time since assuming Japan’s leadership. She stated that Japan would pursue a pragmatic path toward a world where nuclear weapons are never used, citing the Nuclear Non-Proliferation Treaty as a key element of this strategy. She also highlighted Japan’s three non-nuclear principles, which have been firmly established.
Nuclear arms diplomacy faces mounting challenges
The commemoration occurred less than three months after the 2026 Nuclear Non-Proliferation Treaty Review Conference concluded without reaching a substantial consensus document. This marked the third consecutive NPT review session to end without an agreement. Hiroshima underscored this outcome in its call for intensified disarmament efforts. While Japan continues to support the NPT framework, it has not signed the Treaty on the Prohibition of Nuclear Weapons and remains reliant on extended nuclear deterrence through its security alliance with the United States.
UN Secretary-General António Guterres addressed the anniversary via a message read aloud by UN disarmament chief Izumi Nakamitsu. He pointed to increasing geopolitical divides, rising mistrust, and mounting pressures on international arms control initiatives. Guterres warned that the long-term reductions in global nuclear arsenals have begun to reverse. The United Nations urged diplomacy, dialogue, adherence to international law, and multilateral cooperation as nations face renewed nuclear risks and work towards disarmament.
Testimonies from survivors continue to shape Hiroshima’s remembrance
Japan officially recognizes 91,105 atomic bomb survivors, whose average age now exceeds 86. As the hibakusha population diminishes, efforts to document and preserve their firsthand experiences of Hiroshima and Nagasaki have intensified. Survivors have shared accounts of the explosion, fires, radiation exposure, and long-term health effects spanning generations. Many have also actively advocated for nuclear disarmament. Children representing Hiroshima took part in Thursday’s ceremony, offering a pledge for peace. The city maintains a legacy of survivor stories through museums, educational initiatives, and memorial events.
By the end of 1945, the Hiroshima bombing had caused approximately 140,000 deaths. Three days later, the United States dropped a second atomic bomb on Nagasaki, resulting in about 70,000 fatalities by year’s end. Japan announced its surrender on August 15, ending the war. Hiroshima subsequently developed Peace Memorial Park as a central site for remembrance and peace education. On the 81st anniversary, the city reiterated its commitment to nuclear abolition and highlighted the enduring human impact of atomic warfare.
