Not so long ago, young Japanese women lived in terminal fear of becoming
christmas cakes. Their predetermined
goal in life was to find a husband a become a
housewife. Higher education for them was seen mostly as an asset in the
marriage market, not the foundation of a career.
The OL profession came into being as a way to kill time while looking for a husband, and as a way to meet prospective husbands. Many a married couple first met in the office.
Nowadays, all of this is becoming less universally true as Japanese society is changing.
