This paper finds that after controlling for the endogeneity of family structure, coresidence with one's own parents or in-laws has a significant positive effect on Japanese married women's labor force participation. This suggests that coresidence allows married women to share the burden of household work with their parents or in-laws, thus leading to the increased probability of labor force participation. It is also found that married women are more likely to reside with parents-in-law if their husband is the eldest son. This suggests the persistence of the traditional Japanese value that the eldest son is more responsible for family matters.
