Workers placed final fixtures at Hiroshima’s Peace Memorial Park on Tuesday as Japan completes preparations for a ceremony on 6 August marking 80 years since the city was destroyed by an American atomic bomb. Municipal officials said the event will include a minute of silence at 8:15 a.m.—the time of detonation in 1945—and the release of doves by students. Representatives of some 90 countries are expected, alongside aging survivors and families of the roughly 140,000 people who died by the end of 1945. The anniversary comes amid renewed concern over nuclear proliferation and rising geopolitical tension. In Tokyo, Prime Minister Shigeru Ishiba has revived calls for ‘nuclear sharing’ arrangements with the United States, arguing that an expanded deterrent is needed against North Korea, China and Russia. The proposal has drawn resistance from survivor groups and much of the public, underscoring what analysts call Japan’s enduring “nuclear allergy” even as regional security calculations shift. Organisers say this year’s memorial will emphasise disarmament, with U.N. Secretary-General António Guterres scheduled to deliver a recorded message urging states to ratify the Treaty on the Prohibition of Nuclear Weapons. Local authorities have tightened security around the Atomic Bomb Dome and installed real-time multilingual guides in expectation of the largest attendance since the pandemic. A sister service will be held in Nagasaki on 9 August.
