Declining fertility is a common concern in high-income countries. One central cause is the gendered division of labor between spouses, in which women perform most domestic labor regardless of their education and career prospects, while men specialize in market work. This paper studies how this division shapes fertility through the non-pecuniary costs it imposes on women, including the disutility of a disproportionate childcare burden and lost career fulfillment, which vary with their gender role attitudes. Using data from the Japanese Panel Survey of Consumers, I estimate a life-cycle model in which spouses jointly decide on time allocation and fertility. The results show that gender role attitudes determine how women perceive the unequal division of labor and thereby shape their fertility decisions. Husbands’ long working hours limit their involvement in childcare, and reducing these hours raises fertility, particularly among progressive women. Moreover, a more equal allocation of paid and unpaid work between spouses preserves or increase the fertility gains, suggesting that greater gender equality need not come at the expense of fertility.
