Was not a lot of B-29 damage incendiary bombs on Tokyo?
I understood the city was systematically burnt to the ground by fire bombing in sectors to inflict the most civilian deaths...
That is actually a myth, the firebombing of Tokyo was never intended to inflict the most civilian deaths or the raids to be used as "terror raids" against the civilian population. The parts of Tokyo that were fire bombed were actually military targets as a lot of these civilian districts housed factories to make parts for weapons, ships, planes, vehicles, etc. A lot of the Japanese industry wasn't housed in large factories like you saw in the States, but rather were spread out amongst small workshop/factories that were located within these civilian districts. The civilians that lived in these districts would also worked in these workshop/factories.
Because of the decentralized nature of Japanese industry, it was tough to target strategic production facilities as while bombing these would destroy the end product, the small factories that made the parts were still operating. Massive carpet bombing with regular bombs wasn't effective, so it was decided to switch to incendiary bombs as they would be far more effective as they'd burn out the neighborhood, destroying whatever small workshop/factories that were there and the added benefit of killing the skilled labor it took to operate the machinery and produce the parts needed for Japan's war machine.
