Bullshit, I have an uncle and a friend who were raised with 3 sisters. They did not know how to do housework at all because the sisters took care of that. They only learn when they finally leave the house.

That's because the sisters and mother aren't the dominant ones in the house. In Fuji's household, his father is on the weaker side in authority.
One that has more authority usually dictate how to raise a kid.
