HIROSHIMA, JAPAN / RankWire.AI / – Hiroshima commemorated the 81st anniversary of the atomic bombing on Thursday by reiterating calls for global nuclear disarmament. Mayor Kazumi Matsui presided over the annual Peace Memorial Ceremony held at Peace Memorial Park. Attendees included survivors, families, Japanese officials, and international delegates gathered near the Atomic Bomb Dome. At 8:15 a.m., a bell rang out precisely when the bomb detonated on August 6, 1945. The assembly then observed a minute of silence to honor those who lost their lives.
During the event, Matsui used the city’s Peace Declaration to urge leaders of nations to move away from reliance on nuclear deterrence. He emphasized the need for nuclear-armed countries to confront the human toll of atomic warfare. Additionally, Matsui called on political figures to visit Hiroshima and Nagasaki and listen to the stories of survivors, known as hibakusha. These testimonies have been central to Hiroshima’s annual memorials for many years. For decades, the city has used this ceremony to advocate for nuclear abolition and to remember the devastation caused by the bombing.
This year’s ceremony saw approximately 50,000 attendees. Representatives from 121 countries and regions participated, along with the European Union. Prime Minister Sanae Takaichi attended for the first time since assuming Japan’s leadership. She stated that Japan would pursue a pragmatic path toward a future where nuclear weapons are never used. Takaichi highlighted the Nuclear Non-Proliferation Treaty as a key framework supporting that effort. She also referenced Japan’s long-standing three non-nuclear principles.
Nuclear weapons diplomacy faces ongoing challenges
The observance occurred less than three months after the 2026 Nuclear Non-Proliferation Treaty Review Conference concluded without reaching a meaningful consensus document. It marked the third consecutive NPT review summit to end without agreement. Hiroshima pointed to this outcome to strengthen its appeal for more vigorous disarmament initiatives. Japan continues to endorse the NPT regime but has not ratified the Treaty on the Prohibition of Nuclear Weapons. The country also maintains extended nuclear deterrence through its alliance with the United States.
UN Secretary-General António Guterres addressed the anniversary via a message delivered at the ceremony. UN disarmament chief Izumi Nakamitsu read the message on his behalf. Guterres cited increasing geopolitical divisions, mutual mistrust, and mounting pressure on arms control efforts worldwide. He noted that reductions in nuclear arsenals, which had persisted for decades, are beginning to reverse. The United Nations called for diplomacy, dialogue, adherence to international law, and multilateral cooperation as nations face renewed nuclear risks and work toward disarmament.
Testimonies from survivors continue to shape Hiroshima’s memorialization
Japan officially recognizes 91,105 atomic bomb survivors, with their average age now over 86. As the survivor population dwindles, efforts to record and preserve their firsthand accounts have intensified. Survivors have shared experiences of the blast, fires, radiation exposure, and health effects that span generations. Many have also actively campaigned for nuclear abolition. Children representing Hiroshima participated in Thursday’s ceremony, reaffirming their commitment to peace. The city continues to safeguard survivor stories through museums, educational initiatives, and memorial activities.
By the end of 1945, the Hiroshima bombing resulted in an estimated 140,000 deaths. Three days later, the United States dropped a second atomic bomb on Nagasaki, killing around 70,000 people by year’s end. Japan announced its surrender on August 15, bringing World War II to an end. Hiroshima later established Peace Memorial Park as a hub for remembrance and peace education. On its 81st anniversary, the city reiterated its message promoting nuclear disarmament and highlighting the enduring human toll of atomic warfare.
