During the bubble years in Japan, women were said to be looking for the “Three Highs” in men (3高): Height (高身長), High income (高収入), and High education (高学歴). (It was also preferable if the man was not the first-born son due to all the incumbent responsibilities.)
In the ‘90s, the “Three Cs” were sought after: Comfortable (annual income over ¥7m), Communicative, and Cooperative (i.e. someone who helped around the house).
In the 2000s, the Four Lows were popular with women (3低): Low Posture (低姿勢, humble), Low Dependency (低依存), Low Risk (底リスク), and Low Maintenance (低燃費).
Today, modern Japanese women are said to be looking for the “Three Warms” (3温): Kindness, Affection and Peace of Mind. As for the Three Highs of the bubble years, Height now ranks 7th, High Income ranks 10th, and Income is 19th.
