Two days when nuclear weapons
killed hundreds of thousands

On 6 August 1945, the US dropped an atomic bomb called “Little Boy” on Hiroshima in Japan. Three days later a second atomic bomb called “Fat Man” was dropped on the city of Nagasaki.

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 range from 100,000 to 180,000, out of a population of 350,000. Casualties from Nagasaki are thought to be between 50,000 and 100,000. By 1950, over 340,000 people had died as a result and generations were poisoned by radiation.

Cherry blossom

Many people picture cherry blossoms when they think of Japan. The custom of Hanami – cherry blossom viewing parties – is practiced 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.

The Hibakusha

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


The Never Again appeal

‘After I die, I want future generations to know what happened to us.’

– Tsutomu Yamaguchi, survivor of the Hiroshima and Nagasaki bombings

Survivors of the Hiroshima and Nagasaki atomic bombings have helped drive the movement against nuclear weapons for over 70 years. Please donate to our appeal to make sure the stories of the Hibakusha continue to be told and strengthen our campaign to prevent another Hiroshima or Nagasaki.
