Was Japan angry at America after World War II?
The Japanese were much worse than they are portrayed in the movies, especially in the war they were at their worst.
They were extremely cruel and despised the lives of their enemies, this is now a historical fact known to those who cared a little. But the worst victims were the prisoners of war.
This is because, in his code of conduct, it is a seriously dishonorable act to be captured. Better dead than dishonored.
Consequently, prisoners were severely punished for being captured.
A friend of relatives who had lived abroad for decades was captured and lived for two years in a Japanese prison camp.
When he returned home, it was a living skeleton with a permanent expression of pain reminiscent of the photo below. He had been a slave in the construction of a railroad.
Many died of exhaustion or were executed for the amusement of the guards, an incredibly barbaric behavior for a civilized people like the Japanese.
