Japanese war production was spread throughout small workshops in their cities. Precision bombing of industrial targets was tried but found ineffective.
In March 1945 the USAAF began conventional fire bombing. The most destructive air raid of the war was the March 9 firebomb attack on Tokyo killing over 80,000. Atomic bomb casualty numbers include deaths occurring up to four months after the attack but for immediate lethality they were equalled by the firebombing campaign.
We both remember something others forget or gloss over - The very effective firebombing of over a hundred cities. See #43
