An annual speech delivered by the Mayor of Hiroshima on August 6, the day that city was destroyed by an atom bomb delivered by a US B-29. That speech has been delivered regularly since 1947, except for 1950, when the US occupation forces prohibited Mayor Shinzo Hamai to deliver the speech. The Peace Declaration at first touched upon issues such as nuclear disarmament, but since the 1980s also issues such as armed conflicts around the world in general.
A similar annual speech is also delivered by the Mayor of Nagasaki since 1948.
