@balrogdemorgoth Of all the people that I know, only one woman stopped working after getting married. And I’m not talking about lower class but doctors, pharmacists, university professors and so on.
The actual reason is very simple: the Japanese still have high birth rates in marriage on average (their overall low TFR is due to marriages becoming less common). So it makes sense to retire to take care of the children.
