HIROSHIMA, JAPAN / RankWire.AI / – The 81st anniversary of the atomic bombing was marked in Hiroshima with a strong appeal to end nuclear arms. Mayor Kazumi Matsui delivered a speech at the city’s Peace Memorial Park to survivors, families, officials, and international guests. At precisely 8:15 a.m., the time when the bomb detonated over Hiroshima on August 6, 1945, a bell was rung, followed by a minute of silence to honor those affected by the attack and its aftermath.
During Hiroshima’s annual Peace Declaration, Matsui challenged the ongoing dependence on nuclear deterrence. He called on leaders of nuclear-armed nations to acknowledge the humanitarian toll of atomic weapons and to push for disarmament. The mayor also urged policymakers to visit Hiroshima and Nagasaki and listen firsthand to hibakusha, the survivors of both bombings. For decades, Hiroshima has prioritized survivor testimonies and nuclear abolition as key elements of its memorial and peace initiatives.
Approximately 50,000 people participated in the ceremony, with representatives from 121 countries and regions present, including European Union. For the first time as Japan’s prime minister, Prime Minister Sanae Takaichi attended Hiroshima’s memorial. She expressed Japan’s commitment to pursuing a pragmatic approach toward a world without nuclear weapons. Takaichi highlighted the Nuclear Non-Proliferation Treaty as a vital framework for disarmament and reaffirmed Japan’s longstanding three non-nuclear principles.
Nuclear diplomacy endures challenges
The ceremony took place after the 2026 Nuclear Non-Proliferation Treaty Review Conference concluded in May without agreement on a final, substantive document. This marked the third consecutive NPT review conference to end without reaching consensus. Matsui referenced the current international climate while urging governments to intensify efforts toward nuclear disarmament. Japan advocates for the NPT framework but has not acceded to the Treaty on the Prohibition of Nuclear Weapons. The country remains under the protection of the United States nuclear umbrella through their security alliance.
During the Hiroshima event, a message from Secretary-General António Guterres was read by UN disarmament chief Izumi Nakamitsu. The message, delivered on behalf of Guterres, pointed to increasing geopolitical divisions, growing mistrust, and renewed pressures on long-standing nuclear arms control agreements. He also warned that the decades-long reductions in global nuclear arsenals are beginning to reverse. The United Nations emphasized the importance of diplomacy, dialogue, international law, and multilateral cooperation to promote nuclear disarmament.
The legacy of hibakusha remains vital to Hiroshima’s identity
Japan officially recognizes 91,105 atomic bomb survivors, known as hibakusha, whose average age now exceeds 86. As their numbers decline, the urgency to preserve firsthand accounts from Hiroshima and Nagasaki grows. Survivors have dedicated decades to describing the impact of the explosions, fires, and radiation, while advocating for the complete abolition of nuclear weapons. Children representing Hiroshima also took part in Thursday’s ceremony, reaffirming their commitment to peace. The city continues to uphold 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, causing approximately 70,000 casualties by the end of that year. Japan announced its surrender on August 15, leading to the official conclusion of World War II in September. Hiroshima later established Peace Memorial Park as a site for remembrance and peace education. Eighty-one years after the attack, Hiroshima reaffirms its message, centering on nuclear abolition and the human toll of atomic warfare.
