 In total, Allied aircraft dropped 656,400 tons of bombs on Japanese targets, 160,800 tons on the home islands.This was much smaller than the 2,770,000 tons dropped over Europe, or even the 1,415,745 tons on Germany.After initial attacks from high-altitude precision bombing in which less than 10% of the bombs fell near their targets, Allied air forces switched to low-level night-time incendiary attacks against Japanese cities.
