The firebombing of Tokyo occurred during World War II, primarily on the night of March 9-10, 1945. American forces conducted a massive aerial attack using incendiary bombs, targeting the densely populated urban areas. The goal was to destroy Japanese industrial capabilities and weaken morale. The raid resulted in widespread devastation, with an estimated 100,000 casualties and over a million people left homeless. The intense heat and firestorms created by the bombing caused extensive damage to buildings and infrastructure, marking it as one of the most destructive air raids in history.
