Two answers to how many Japs were sentenced to death for war crimes after World War II.
1) Just under 1000.
2) Not enough.
I will have to look for exact stats - but post-war “denazification” in Germany executed, imprisoned or otherwise purged something like 5% of all German officials, military officers, government bureaus, etc...
In Japan, the figure was much lower - something like 0.2%
My late uncle, who served there in the Army’s Americal division, would vote B. He never talked much of his experiences there to anyone, but he had absolute hatred toward the Japanese until the day he died.
The Allies executed far more Japanese war criminals than Nazi war criminals, at least twice as many.
At least the Soviets had the right idea.
