Mayors of the cities of Hiroshima and Nagasaki deliver a Peace Declaration every year on the anniversary of the atomic bombing of their respective cities — Aug. 6 for Hiroshima and Aug. 9 for Nagasaki.

Although the declarations’ histories and the ways in which their citizens became involved in the draft-making process differ, the two declarations have played a significant role in representing the voices of the cities hit by the devastating attacks to the world.

But the messages of the two cities may be harder to spread with scaled down ceremonies amid the global COVID-19 pandemic.
