I heard they get pressured to leave their jobs when they get pregnant
And given how the men are encouraged to work like 80 hours a week if you count "drinking with boss hours", they pretty much raise the kids alone
Both genders don't want kids or marriage because of how awful work culture is over there
Modern era Japan wants women to work full time AND be full time mothers.
Having countries run by shithead politicians who never spend any time raising their own kids, and just pay other people to raise their kids for them, really sucks when it comes to stuff like this. Those fools have no idea how hard raising kids is, and that it's a full time job with no breaks or vacations.
Like, if you have kids, and take your kids to vacation at Disney Land, YOU ARE NOT GOING ON VACATION, your kids are.
Japanese women are wizening up and realizing the moment they have a baby, their life is fucked. So, no babies until the old people stop being fucking morons.
