History of Nagasaki Memorial Day
On August 6, 1945, to compel Japan to surrender and end World War II, U.S. bomber Enola Gay dropped Little Boy, the first atomic bomb ever used in wartime, on the Japanese city of Hiroshima. The explosion killed an estimated 80,000 people, and thousands more died later because of radiation exposure. Japan had caused many Allied casualties during the war, and despite the devastation, did not surrender. As a result, the U.S. decided to drop a second bomb to compel Japan to surrender.
On August 9, 1945, three days after the first hit, U.S. bomber Bockscar dropped a bomb called Fat Man on the city of Nagasaki. The bomb contained power equivalent to 22,000 tons of T.N.T. The explosion had devastating consequences on Nagasaki, causing the death of an estimated 40,000 people. More inhabitants died later from burns, radiation sickness, and other injuries. But, the bomb’s effect was diminished, because Nagasaki was nestled in narrow valleys between mountains and had a smaller population. After this second bombing, Japanese emperor Hirohito announced his country’s surrender on a radio broadcast on August 15, 1945 (Japanese time).
On September 2, 1945, a formal surrender agreement was signed aboard the American battleship U.S.S. “Missouri” anchored in Tokyo Bay, leading to the end of World War II. The two bombings caused the deaths of an estimated 70,000 to 135,000 people in Hiroshima and 60,000 to 80,000 people in Nagasaki. For that reason, Nagasaki Memorial Day is observed to commemorate the bombing victims, promote peace and raise awareness of the importance of avoiding more wars and the destructive potential of nuclear weapons.
