Answer:
The Bombing of Tokyo was a series of firebombing air raids by the United States Army Air Forces during the Pacific campaigns of World War II. Operation Meetinghouse, which was conducted on the night of 9–10 March 1945, is regarded as the single most destructive bombing raid in human history.[1] 16 square miles (41 km2; 10,000 acres) of central Tokyo were destroyed, leaving an estimated 100,000 civilians dead and over one million homeless.
The US first mounted a seaborne, small-scale air raid on Tokyo in April 1942. Strategic bombing and urban area bombing began in 1944 after the long-range B-29 Superfortress bomber entered service, first deployed from China and thereafter the Mariana Islands. B-29 raids from those islands began on 17 November 1944, and lasted until 15 August 1945, the day of Japanese surrender.]
Over 50% of Tokyo's industry was spread out among residential and commercial neighborhoods; firebombing cut the whole city's output in half.Some post-war analysts have called the raid a war crime due to the targeting of civilian infrastructure and the ensuing mass loss of civilian life.
