When German or Japanese women gained suffrage isn't relevant.
It's entirely relevant, as it speaks to social attitudes within those countries toward women.
The women subject to enslavement by the Japanese govt were mostly Korean;
The supposition that they were mostly Korean was based on the fact that little scholarship had come out of China quantifying the enslavement of Chinese women. Fortunately for posterity (although not for women), that's now changing. It's taken as read that the Japanese military enslaved women in every country they invaded, "administered" and otherwise occupied
just as the women suffering the depredations of the German Army weren't the 'aryan' german women considered to be full citizens: it was the minorities, the Jewish women, the women of subject territories.
So in your opinion, men can and do entirely switch off any social conditioning regarding how they interact with the opposite sex, on the basis of a political belief system they may not even support?
And for those who did buy into the political belief system, why would they be willing to transgress one of the foremost tenets of that belief system - racial hygiene?
I think your argument is poor. It essentialises all men into an amorphous homogenised mass of testosterone, unable to control themselves. Kind of like the way black males used to be essentialised, come to think of it.
Hitler's power at its height at least equalled that of the Emperor, and arguably the cult of personality was as strong.
And these opinions are based on...?
Bear in mind that the cult of the emperor was centuries old, and was fueled at that time by the angst caused by the part-industrial/part-feudal nature of Japan, and was focused not on the personality, but on the divine right embodied in the office, not the office holder.
Hitler's personality cult, on the other hand, was a product not of centuries of accumulated beliefs, it was a product of political propaganda that not even all party-members bought into, and adoption was latterly "encouraged" by the realisation that the regime was as willing to practice night and fog on it's own citizens as on foreigners.
The Japanese Imperial High Command ran the war - ran many things, with the Emperor acting mostly as a rubber stamp.
The emperor was commander in chief of the Japanese military.
Hitler was the Commander in Chief of the Army, the Head of State, amongst other titles. He took over more and more control of military operations as time went by.
Not "as time went by". His obsession for "total control" is easily dated. It stems from the first large reversals in fortune in Soviet territories, as do the executions of generals. Before that Hitler was, as with so many things he involved himself in, a dilitante in military strategy.
