Hiroshima Day is observed every year on 6th August to remember the horrific atomic bombing of Hiroshima in 1945. It is a day of reflection, sorrow, and hope for a peaceful future. While the tragedy caused immense suffering, Hiroshima Day also stands as a strong call for peace and a reminder that nuclear weapons should never be used again.
Why Hiroshima Day is Important
The bombing of Hiroshima was the first time in history that an atomic bomb was used in war. The devastating attack left behind memories of destruction and pain that the world can never forget. Hiroshima Day is important because it:
- Remembers the innocent lives lost.
- Honors the survivors, known as Hibakusha, who faced lifelong health struggles.
- Warns the world about the catastrophic dangers of nuclear weapons.
- Inspires nations to work together for a future free from nuclear war.
Hiroshima Day and the Second World War
To understand Hiroshima Day, we need to look at the events of the Second World War.
- The Second World War lasted from 1939 to 1945, involving many countries.
- By mid-1945, Japan was still fighting against the United States and its allies.
- On 6th August 1945, an American bomber plane dropped the first atomic bomb on Hiroshima. The bomb was named “Little Boy.”
- Just three days later, on 9th August 1945, another atomic bomb named “Fat Man” was dropped on Nagasaki.
- After these two bombings, Japan surrendered on 15th August 1945, which brought the war to an end.
Thus, Hiroshima Day became a turning point in world history, reminding humanity of the cost of war.
