HIROSHIMA, JAPAN / RankWire.AI / – On Thursday, Hiroshima observed the 81st anniversary of the 1945 atomic bombing with a renewed appeal for the abolition of nuclear arms. Mayor Kazumi Matsui delivered his address at the city’s Peace Memorial Park, where he spoke to survivors, their families, officials from various governments, and international delegates. At precisely 8:15 a.m., a bell sounded to mark the exact moment when the atomic bomb detonated over Hiroshima on August 6, 1945, after which attendees observed a minute of silence to honor the victims and those affected by the attack and its consequences.
In his annual Peace Declaration, Matsui challenged the persistent reliance on nuclear deterrence by urging political leaders in nations armed with nuclear weapons to acknowledge the profound humanitarian repercussions associated with atomic arms and to promote disarmament initiatives. Additionally, the mayor emphasized the importance of policymakers visiting Hiroshima and Nagasaki to hear firsthand accounts from hibakusha, the survivors of the two nuclear bombings, noting that Hiroshima has long prioritized survivor testimonies and nuclear disarmament as key elements of its international peace advocacy and commemorative activities.
Approximately 50,000 individuals attended the event, with representatives from 121 countries and regions participating alongside the European Union. For the first time in her role as Japan’s prime minister, Sanae Takaichi attended the Hiroshima memorial, where she declared that Japan would pursue a pragmatic path toward establishing a world where nuclear weapons are never used. She further highlighted the Nuclear Non-Proliferation Treaty as a vital framework for disarmament efforts and reaffirmed Japan’s longstanding adherence to its three non-nuclear principles.
Nuclear diplomacy continues to face mounting challenges
This year’s ceremony took place shortly after the conclusion of the 2026 Nuclear Non-Proliferation Treaty Review Conference in May, which failed to reach consensus on a substantive final document, marking the third consecutive NPT review to end without agreement. Matsui pointed to the current international climate and urged governments to intensify efforts toward nuclear disarmament, even as Japan supports the NPT framework but has not ratified the Treaty on the Prohibition of Nuclear Weapons. The country remains protected under the U.S. nuclear umbrella as part of its security alliance.
During the Hiroshima event, a message from Secretary-General António Guterres was delivered by UN disarmament chief Izumi Nakamitsu, via United Nations. Guterres highlighted the growing geopolitical divisions, rising mistrust, and renewed pressures on long-standing arms control agreements, noting that the decades-long reductions in nuclear arsenals are beginning to reverse. The UN called for increased diplomatic engagement, dialogue, adherence to international law, and multilateral cooperation to further nuclear disarmament efforts.
The legacy of hibakusha remains vital to Hiroshima’s identity
Japan officially recognizes 91,105 hibakusha, or atomic bomb survivors, whose average age now exceeds 86, underscoring the urgent need to preserve their firsthand stories about Hiroshima and Nagasaki. For decades, survivors have shared detailed accounts of the effects of the explosions, fires, and radiation, continuously advocating for the complete eradication of nuclear weapons. Children representing Hiroshima also participated in the Thursday ceremony, expressing their commitment to peace. The city continues to uphold survivor testimonies through memorial initiatives, museums, and public education programs.
The atomic bombing of Hiroshima resulted in an estimated 140,000 deaths by the end of 1945. Three days later, the United States dropped another nuclear bomb on Nagasaki, causing approximately 70,000 fatalities 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 subsequently established Peace Memorial Park as a hub for remembrance and peace education. Eighty-one years after the attack, the city again emphasizes nuclear abolition and the human toll of atomic warfare at the core of its message.
