On 6 August 1945, the US dropped an atomic bomb called “Little Boy” on Hiroshima in Japan. Three days later a second atomic bomb (“Fat Man”) was dropped on the city of Nagasaki. These are the only times nuclear weapons have been used in war.

The firestorm in Hiroshima destroyed five square miles of the city. Almost 63% of the buildings in Hiroshima were destroyed after the bombing and nearly 92% of the structures in the city were destroyed or damaged by blast and fire.

Estimates of total deaths in Hiroshima have generally ranged between 100,000 and 180,000, out of a population of 350,000. Casualties from Nagasaki are thought to be between 50,000 and 100,000.

“We are the survivors of the nuclear bombs that hit our home cities”


Cherry blossom

Many people picture cherry blossoms when they think of Japan. The custom of Hanami – cherry blossom viewing parties – is practised across Japan during Spring. In Hiroshima and Nagasaki, hundreds of cherry blossom trees were planted in peace parks established in the decade after the atomic bombs destroyed the two cities. Cherry blossoms are therefore a symbol of peace and hope. Out of devastation, new life and beauty can grow if it is respected and nurtured as the cherry blossom trees in those cities are today.

Please help support our Hiroshima and Nagasaki remembrance activities and our campaign to get rid of nuclear weapons by making a donation on the Never Again appeal.
