The Japanese Equal Employment Opportunity Act (EEOA) of 1985 aimed to reduce gender discrimination in the labor market, especially for career-oriented jobs. This paper investigates whether this act had an unanticipated effect on women\u27s marriage decisions. Using micro data from the Japanese Panel Survey of Consumers, we model women\u27s interrelated decisions on university education and whether to marry, focusing on whether women have married by age 32. Our results show a negative relationship between university education and marriage that is much greater for post-EEOA cohorts of women than for pre-EEOA cohorts, consistent with our hypothesis that the enhanced career opportunities associated with the EEOA stimulated women to delay or forgo marriage
