HIROSHIMA Day - August 6

➡️ THE ATOMIC BOMBING OF HIROSHIMA – 80 Years Since the Nuclear Holocaust

The U.S. atomic bombing of the Japanese city Hiroshima on August 6, 1945, marked the first time in world history that a nuclear weapon was deployed. This put an end to WWII. The bomb immediately killed 80,000 people, mostly civilians, and flattened and burnt 70% of everything within a one-mile radius.

There were an estimated 140,000 deaths by the end of 1945, along with the terrible side effects caused by radiation amongst the survivors.

The equally catastrophic U.S. nuclear bombing of ➡️ NAGASAKI took place just a few days later on August 9th - an act which Oppenheimer himself believed was unnecessary and unjustified.

This year, 2025, marks 80 years since the bombing, yet there are still over 12,000 nuclear weapons in existence on the planet.

Hiroshima Commemorations Worldwide

Better World Info pays tribute to the victims and campaigns for nuclear weapon disarmament. It contains over 450 essential resources on the devastating long-term effects, the victims, videos, organisations, and the events that led to such a horrifying decision to be made.

Find information on the memorial services paying tribute to all the lives lost over the decades, such as the annual peace ceremony in Hiroshima Peace Memorial Park, events at the Peace Pagoda and Children's Peace Monument, lantern floating ceremonies, and the significance of Sadako Sasaki and her origami paper cranes.

How to Curb & Ban Nuclear Weapons - Treaties & Organisations

In our guide to Nuclear Disarmament, discover the organisations working hard to ban the manufacturing and proliferation of nuclear weapons, such as ICAN, IPPNW, Abolition 2000, and CND UK. Learn about the legally binding treaties in place to prevent such catastrophic events from happening again, such as the TPNW, the NPT, the New Start treaty, and nuclear-weapon-free zones. Additionally, discover a comprehensive guide to the work of physicist J. Robert Oppenheimer, the father of the atomic bomb, who later became a nuclear arms control advocate.

The only solution to this nuclear weapon madness is an outright ban. The risk of nuclear escalation in the Russia-Ukraine war has put the world on the brink of nuclear disaster. It is more important now than ever for our world leaders to step up and commit to a nuclear-weapon-free world. Stockpiling nuclear weapons for so-called deterrence is merely a thin veil for potential mass murder and genocide!

The Forgotten Korean A-bomb Victims

Over 20,000 Koreans who had been brought to Japan as forced labourers under Japanese colonial rule also died when the atomic bombs were dropped. In Hiroshima, they accounted for 10% of the death toll. Many worked in munitions factories, shipyards, or mines under dangerous conditions. Among the victims were Korean women who were forced into sexual exploitation in military brothels as so-called "comfort women." Their exact number has never been quantified, but estimates are around several thousand. These people were at the bottom of society - disenfranchised, racially discriminated against, and often silenced in both countries after the war.

Only since the 1990s has public pressure grown to make their history visible. In Hiroshima, a special memorial in the Peace Park has commemorated the Korean victims since 1970. It was only officially recognised by the mayor in 2015, after it had previously been erected by the Korean community without official permission.

Calling Experts & Peace Activists

We must ensure that the horrors of 1945 are never repeated. By keeping the memory of the victims alive, we remember the devastating humanitarian consequences of nuclear warheads and promote the cooperation of all nations and people to ensure that nuclear weapons are never used again.
