Sex is actually a way of reducing stress and a good exercise as you can sweat out the extra toxin and also burn away some calories. Therefore, its a good way to maintain a healthy lifestyle in a hectic society today.
I used to work in a Japanese MNC and yes they do take care of family life and have days like families day where they let you get off work early. Home for those with families and out for those with gf.
It's stupid how people believe the propaganda involved. The issue is severe because Japan realizes its' one of the last countries to preserve an ancient culture independent from the 'West'. Population is of course an issue, as w/ all sovereign issues.
