HIROSHIMA, JAPAN / RankWire.AI / – The city of Hiroshima marked the 81st anniversary of the 1945 atomic attack with a renewed appeal for nuclear disarmament, led by local authorities and international representatives. Mayor Kazumi Matsui addressed attendees including survivors, families, government officials, and foreign delegates at Hiroshima’s Peace Memorial Park. At 8:15 a.m., the same moment the atomic bomb was detonated over Hiroshima on August 6, 1945, a bell sounded, after which a minute of silence was observed to honor those affected by the attack and its aftermath.
During Hiroshima’s annual Peace Declaration, Matsui challenged the ongoing dependence on nuclear deterrence, urging political leaders in nuclear-armed nations to acknowledge the humanitarian impacts of atomic weapons and push for disarmament. He also encouraged policymakers to visit Hiroshima and Nagasaki and to listen directly to hibakusha, the survivors of the bombings. For decades, Hiroshima has centered survivor testimonies and nuclear abolition within its commemorations and global peace initiatives.
Approximately 50,000 individuals attended the event, with representatives from 121 countries and regions participating, including the European Union. Prime Minister Sanae Takaichi took part in the Hiroshima memorial for the first time as Japan’s leader. She expressed Japan’s commitment to a realistic approach toward achieving a world where nuclear weapons are never used. Takaichi also highlighted the Nuclear Non-Proliferation Treaty as a vital framework for disarmament and reaffirmed Japan’s longstanding three non-nuclear principles.
Nuclear diplomacy continues to face challenges
This year’s ceremony followed the 2026 Nuclear Non-Proliferation Treaty Review Conference, which concluded in May without agreement on a substantive final document. This marked the third consecutive NPT review session to end without consensus. Matsui referenced the current international climate, urging governments to intensify efforts toward nuclear disarmament. Although Japan supports the NPT framework, it has not joined the Treaty on the Prohibition of Nuclear Weapons and remains protected under the United States nuclear umbrella as part of their security alliance.
During the Hiroshima event, the United Nations conveyed a message from Secretary-General António Guterres, which UN disarmament chief Izumi Nakamitsu read aloud. Guterres highlighted the deepening geopolitical divisions, rising mistrust, and renewed pressures that threaten longstanding nuclear arms control efforts. He warned that recent reductions in global nuclear arsenals are beginning to reverse. The UN emphasized the importance of diplomacy, dialogue, international law, and multilateral cooperation to advance nuclear disarmament.
The legacy of hibakusha remains central to Hiroshima’s message
Japan officially recognizes 91,105 atomic bomb survivors, known as hibakusha, whose average age now exceeds 86. Their dwindling numbers have intensified efforts to preserve firsthand accounts of Hiroshima and Nagasaki’s experiences. For decades, survivors have shared their stories of the destructive effects of the explosions, fires, and radiation, advocating for nuclear weapons’ elimination. Children representing Hiroshima also took part in Thursday’s commemoration, expressing their dedication to peace. The city continues to safeguard survivor testimonies through memorial programs, museums, and public education initiatives.
By the end of 1945, the Hiroshima atomic bombing resulted in an estimated 140,000 deaths. Three days later, the United States dropped another atomic bomb on Nagasaki, killing approximately 70,000 people by year’s end. Japan announced its surrender on August 15, leading to the formal conclusion of World War II in September. Hiroshima subsequently established Peace Memorial Park as a hub for remembrance and peace education. Now, 81 years after the attack, the city reaffirms nuclear abolition and the human toll of atomic warfare as core messages of its ongoing efforts.
