At 11.02 a.m., a moment's silence was observed as at this time on August 9, 1945, a US B-29 bomber dropped a plutonium-core atomic bomb, nicknamed Fat Man, killing around 74,000 people in Nagasaki by the end of that year.

The annual ceremony this year allowed for more people to attend, owing to the easing of Covid-19 restrictions in the last two years.
