Japan Is not the only place that has hentai.
Amercia has done some Pornographic cartoons too. Also American artists. Other countries have also done it. Plus this is racist in a way. I do not see how any of it is funny to be honest. Also you could at least have done better animation and at least make an atempt to get your point across. And sure Japan did attack Pearl Harbor but that is in the past. Thousands of people died on both sides and nobody wants war. Why don't you do some history check up because There are worse countries. Don't blame a whole country blame different people like pervets or something.
