Oh please, let's stop with the bullshit of putting everything on otaku when the problem is much bigger than this and it's very ingrainted with japanese culture even before anime and manga existed (yes, unfortunately I have to refer to otaku as this even when the term serves to many more interests). Japan has a problem with it's treatment of women way before it, the very vision that women should be pure, on how they should act, that women should give children to men and many other problems. Japanese entertainment media have this problem because of Japan itself, not because of otaku.
Lastly, let's not forget that the ~otaku culture~ also happens on drama, movies and TV talk shows of Japan not only before this even existed but right now. There's a reason as to why more progressist japanese don't like those parts.
I'm aware the Japanese use of the term otaku is not exclusive to anime fandom. But nonetheless, no one uses anime to mean animation in general outside of Japan. Same concept.
I'm not talking about your average anime otaku who goes to cons and buys some merch, I'm talking the enthusiasts who get deep into it and need this sort of stuff to be amused. I apologise if it seemed like I was generalizing. It's something that's been talked about by those in the anime industry itself- men who know nothing about interacting with real women are making anime with women based upon the fictional women they do know. I assume the same thing applies to games with what seems, to me, to be a sudden recent explosion in this creepy shit. After all, a number of Japanese games do treat their women protagonists with respect- and it seems said games are coming from companies who don't hire otaku who bury themselves in anime and no reality to major creative roles.
However, perhaps you are correct that it (that such a game exists) runs deeper than mere otaku in the workspace, given the example that some J-dramas are even worse. After all, the country as a whole has a problem with many men who just don't see the point in interacting with women. It could be a result of those men as well.
I'm just tired of dismissive comments that treat Japanese culture as this horrible thing with no positives. It's a beautiful culture that needs to have problematic aspects excised, not wholesale dismissed as bad and evil compared to Western culture.
Edit: To be clear, yes, sexism is a serious problem in Japanese culture. It's just, like, even more excessive in games like this, or so I thought.
