This Nagasaki Day 2026 will be observed on 9th August to honour the victims of the atomic bomb dropped on the city of Nagasaki towards the end of World War II and to draw attention to the terrible humanitarian impact of nuclear weaponry. On 9th August, 1945, an atomic bomb code named Fat Man was dropped by the United States on Nagasaki which had been bombed at Hiroshima three days before. It resulted in a huge loss of life and destruction and constituted the second and last nuclear attack ever used in war.

What is Nagasaki Day?

Nagasaki Day is celebrated every year on 9th August in memory of the atomic bombing of Nagasaki in 1945.

It is largely a day of remembrance. It is a tribute to the victims who lost their lives and recognition of the suffering endured by the survivors to raise awareness about the catastrophic impact of nuclear warfare.

Memorial activities in Nagasaki consist of gatherings of survivors along with representatives from all walks of life and from all over the world.

What Happened in Nagasaki on August 9, 1945?

On August 9, 1945, an atomic bomb was dropped by the US forces on Nagasaki in the World War II.

The atomic bomb was named as Fat Man and it consisted of an implosion-type nuclear weapon with a plutonium core and an explosive power of 21 kilotons of TNT.

The bomb was delivered to its target on a B-29 Superfortress bomber named Bockscar which was piloted by Major Charles W. Sweeney.

Initially, the city of Kokura was targeted for bombing, but due to visibility problems, the mission could not be accomplished, and another target, Nagasaki, was chosen.

The bomb exploded in approximately 11:02 a.m. There was a huge damage inflicted on industrial and military facilities, residential districts and infrastructure in the city.

The Fat Man Atomic Bomb

The atomic bomb used to destroy Nagasaki was different from the bomb dropped on Hiroshima.

It consisted of plutonium-239 and had an explosive power of 21 kilotons.

Unlike the previous bomb, Fat Man was detonated above the city and thus inflicted additional damage due to blast, heat and radiation.

The geography of Nagasaki also played an important role because of the hills that were able to limit the impact of the explosion unlike flatter Hiroshima.

Consequences of the Atomic Bombing on Humans

There were numerous victims of the bombing.

The exact number of casualties varied from tens of thousands of deaths during the event itself, through the following period because of the consequences of injuries, burns, and radiation.

Besides death toll, the consequences of bombing included,

• Destruction of residential buildings and public infrastructure
• Damage to hospitals and schools
• Industrial damage
• Burns and injuries
• Radiation
• Psychological consequences
• Displacement of local inhabitants
• Long-term consequences of the bombing

The consequences of being exposed to nuclear radiation of survivors were widely used for further advocacy of nuclear disarmament in the international community.

What Effect Has the Nagasaki Bombing Had on World War II?

The Nagasaki bombing took place few days after the atomic bombing of Hiroshima that occurred on August 6, 1945.

These events, together with fast changes in the political and military situation in the area, led to the decision of the Japanese side to capitulate.

Japan signed the instrument of surrender on August 15, 1945, which ended World War II.

Also, the Nagasaki bombing was one of the events which affected significantly the post-war international relations.
