The American aerial bombing of a total of 65 Japanese cities took from 400,000 to 600,000 civilian lives, with 100,000+ in Tokyo alone, over 200,000 in Hiroshima and Nagasaki combined. The Battle of Okinawa resulted in 80,000–150,000 civilian deaths. In addition civilian death among settlers who died attempting to return to Japan from Manchuria in the winter of 1945 were probably around 100,000. The total of Japanese military fatalities between 1937 and 1945 were 2.1 million; most came in the last year of the war and were caused by starvation or severe malnutrition in garrisons cut off from supplies.John Dower, "Lessons from Iwo Jima," Perspectives (September 2007) 45#6 pp 54–56 at
