HIROSHIMA, JAPAN / RankWire.AI / – Marking the 81st anniversary of the atomic bombing in 1945, Hiroshima on Thursday renewed its appeal for the complete abolition of nuclear weapons. Mayor Kazumi Matsui addressed survivors, family members, government representatives, and international delegates at the Peace Memorial Park in the city. At 8:15 a.m., the exact moment the atomic bomb detonated over Hiroshima on August 6, 1945, a bell was rung, and participants observed a minute of silence to honor those lost to the attack and its aftermath.
During Hiroshima’s annual Peace Declaration, Matsui challenged the reliance on nuclear deterrence, urging world leaders in nuclear-armed nations to acknowledge the humanitarian toll of atomic weapons and push for disarmament. He also called on policymakers to visit Hiroshima and Nagasaki and hear firsthand accounts from hibakusha, the survivors of both bombings. For decades, Hiroshima has centered its remembrance and peace initiatives around survivor testimonies and efforts toward nuclear abolition.
Approximately 50,000 individuals attended the ceremony, with participation from representatives of 121 countries and regions, including the European Union. For the first time as Japan’s prime minister, Prime Minister Sanae Takaichi attended the Hiroshima memorial, stating that Japan will seek a pragmatic approach toward achieving a world where nuclear weapons are never used. Takaichi emphasized the importance of the Nuclear Non-Proliferation Treaty as a fundamental framework for disarmament and reiterated Japan’s long-standing three non-nuclear principles.
Nuclear diplomacy remains under strain
This year’s ceremony followed the conclusion of the 2026 Nuclear Non-Proliferation Treaty Review Conference, which ended in May without reaching an agreement on a substantive final document. This marked the third consecutive NPT review conference to fail to produce consensus. Matsui highlighted the current international climate, urging governments to intensify efforts toward nuclear disarmament. Japan supports the NPT framework but has not signed the Treaty on the Prohibition of Nuclear Weapons. Additionally, the country remains protected by the United States’ nuclear umbrella through their security alliance.
During the Hiroshima event, the United Nations conveyed a message from Secretary-General António Guterres, which was read aloud by UN disarmament chief Izumi Nakamitsu. Guterres pointed to growing geopolitical divisions, rising mistrust, and renewed pressures on longstanding nuclear arms control treaties. He also warned that the decades-long reduction of global nuclear arsenals is beginning to reverse. The UN called for greater diplomatic engagement, dialogue, adherence to international law, and multilateral cooperation to advance nuclear disarmament efforts.
The legacy of hibakusha remains central to Hiroshima’s message
Japan officially recognizes 91,105 hibakusha, or atomic bomb survivors, whose average age now surpasses 86. As their numbers dwindle, there is an increased urgency to preserve their firsthand stories of Hiroshima and Nagasaki. For decades, survivors have shared accounts of the explosions, fires, radiation effects, and have called for the complete eradication of nuclear weapons. Children representing Hiroshima also took part in Thursday’s event, reaffirming their commitment to peace. The city continues to safeguard survivor testimonies through memorial programs, museums, and educational initiatives.
By the end of 1945, the Hiroshima bombing resulted in an estimated 140,000 deaths. Three days later, the United States dropped another atomic bomb on Nagasaki, leading to approximately 70,000 casualties by year’s end. Japan declared its surrender on August 15, with World War II ending officially in September. Hiroshima later established Peace Memorial Park as a site dedicated to remembrance and peace education. Now, 81 years after the attack, Hiroshima again emphasizes nuclear abolition and highlights the human toll of atomic warfare in its ongoing message.
