The Japanese Bombed Oregon.

The U.S. tried bat bombs but the bats went into hibernation when the plane got cold at altitude. It was a huge failure.

Yes, according to wikipoopia, a guy from PA came up with the idea because Japan's building materials were primary wood and paper.

we killed way more people in japan with fire bombs then we did with nukes.  I forget the exact number, but it was between 5 and 10x.

Curtis Lemay implemented the notion of low-level incendiary attacks on Japan, as Japanese industry was too distributed, almost cottage-level in some cases, to use strategic high-level bombing, which had proven to be quite problematic anyhow in Japan since the winds tended to disrupt the bombing patterns rather seriously.

He tested his idea on Chung-do in western China, one of Japan's major outposts. It worked well. TAB is right, something like 350,000 people were killed in a single incendiary raid on Tokyo, whereas the atomic bombs were like 75,000 - 115,000 direct casualties.

Total casualties from both A bombs were around  250,000.
As Path points out many incendiary raids killed that many or more.
