Using the Japanese Study of Aging and Retirement, Japan’s first globally comparable panel survey of the elderly, we estimate the effect on female employment in Japan due to the provision of informal parental care. We observe that informal parental care has little impact on female employment, after controlling for endogeneity of informal care or individual unobserved time-invariant heterogeneity. This finding is consistent with those observed in Europe and the US, underscoring a limited association between care and work in Japan, which is facing ageing at the fastest pace among advanced economies.
