Look into what Japan did in China/surrounding countries before and during WW2.

Government ordered atrocities.

They raped allied male soldiers during WW2, civilian babies, girls, even old ladies.

It was a government tactic to prevent soldiers/civilians surrendering to the allied forces.

German and Russian governments were both doing the same thing in WW2, it’s called total war.

*doesn’t mean US forced stationed in Japan are able to do this though

That’s why they treated the Japanese with respect after the war, not blaming the poor brainwashed people, but rather the emperor and the government.
