Wait! Japanese girls can just choose to wear pants, to school!? This is huge! Now all we have to do, is get the japanese, to stop seeing their women as live in housekeepers, who make babies, and we have a full blown sexual revolution.
The problem Japanese culture has right now is that everyone works, works, works, all day and no one is home to make babies in the first place. Or you get a situation where the husband almost lives at work and the wife basically controls the house to the extent that he's more of a guest when he does come home than an actual resident. But, I digress.
Putting this in a different light: Japanese society has evolved to prevent overpopulation by literally working people so hard that they don't have the time/ energy to procreate.
Half-jokes aside I'm not a fan of Japan's present family model.
