As World War II in the Pacific intensified in 1944–1945, the United States sought to cripple Japan's war-making capacity. The introduction of the long-range B-29 Superfortress enabled strategic bombing of the Japanese home islands at scale. Because much of Tokyo's industry was dispersed across residential and commercial districts, U.S. commanders adopted incendiary area-bombing tactics to destroy both industrial and urban infrastructure.
The USAAF conducted a sustained campaign of air raids on Tokyo from late 1944 through August 1945. The most severe attack, Operation Meetinghouse on the night of 9–10 March 1945, saw B-29s drop incendiary bombs on central Tokyo, destroying sixteen square miles of the city. The raids were preceded by the small-scale Doolittle Raid of April 1942 and escalated after B-29s began operating from the captured Mariana Islands in November 1944.
Operation Meetinghouse left an estimated 100,000 civilians dead and more than one million homeless, making it the deadliest conventional air raid in history. The broader bombing campaign reduced Tokyo's industrial output by half. The raids have since been debated as potential war crimes due to the deliberate targeting of civilian infrastructure, and they preceded Japan's surrender on 15 August 1945.
