According to the reconnaissance photos taken on the spot, about 4 1 square kilometers of land in the center of Tokyo was burned to the ground, and Tokyo 1/4 was razed to the ground, of which 18% was industrial, 63% was commercial and the rest was residential. All the 22 industrial targets planned to be bombed by the US military were burned and reduced to ashes. More than 267,000 buildings were set on fire, 6,543,800 people were homeless, 80,000 people were burned to death, and 6,543,800 people were seriously injured. After the fire, it took Japan 25 days to clean up the broken bricks.

General Bauer later said: "The artillery attack on Tokyo on March 9 was the biggest example of damage caused by a single bombing in the history of war, and its damage was greater than the combined damage caused by the atomic bombings of Hiroshima and Nagasaki. In the history of world wars, this fire attack caused more casualties than any military action. "
