The United States dropped two atomic bombs on Japan in August 1945. The first bomb was dropped on Hiroshima on August 6th, killing around 90,000-166,000 people. The second bomb was dropped on Nagasaki on August 9th, killing around 60,000-80,000 people. In response to the bombings and the Soviet declaration of war, Japan surrendered on August 15th, officially ending World War II. The bombings led Japan to adopt a policy forbidding nuclear weapons.
