Date and Origin
- Annual Observance: Hiroshima Day is observed annually on August 6.
- 2024 Date: This year, it falls on a Tuesday.
- Historical Event: Marks the atomic bombing of Hiroshima, Japan, on August 6, 1945, by the United States during World War II.
- Bombing Details: The bombing was conducted by the B-29 bomber Enola Gay, nicknamed “Little Boy,” which exploded approximately 600 meters above Hiroshima.
- Impact: Instantly killed approximately 70,000-80,000 people, with tens of thousands more succumbing to injuries and radiation exposure. The city’s infrastructure was decimated, and survivors, known as Hibakusha, faced long-term health issues and severe psychological trauma.
- Second Bombing: On August 9, 1945, the U.S. dropped a second atomic bomb, “Fat Man,” on Nagasaki.

- War End: These events marked the first use of nuclear weapons in warfare and led to Japan’s surrender on August 15, 1945, effectively ending World War II.
Background:
Why did the US Enter World War II?
The United States initially adopted a policy of neutrality at the onset of World War II. However, several factors led to its eventual involvement:
- Growing Involvement Before Pearl Harbor: Lend-Lease Act allowed the U.S. to provide military aid to Britain and other Allied nations without officially entering the war.
- Economic Ties: The U.S. economy was increasingly intertwined with the Allied powers, and their defeat posed a significant threat to American economic interests.
- Ideological Concerns: Many Americans were alarmed by the rise of fascism and the aggressive expansionist policies of Germany, Italy, and Japan.
- The Attack on Pearl Harbor: The decisive event that brought the U.S. into the war was the surprise attack on Pearl Harbor by Japan on December 7, 1941. This attack killed thousands of Americans and destroyed much of the U.S. Pacific Fleet. The public outcry was immense, and the U.S. declared war on Japan the following day. Germany and Italy, allies of Japan, subsequently declared war on the U.S.
In summary, the U.S. entered World War II due to a combination of factors, including economic interests, ideological concerns, and the direct military attack on Pearl Harbor.
