In recent years, the number of female doctors passing the National Medical Practitioners Qualifying Examination has increased. Despite the introduction of various official child care support systems, many female doctors still resign after giving birth. In this study, we interviewed 9 female doctors in Hiroshima Prefecture and analyzed the types of child care support they have had access to and what they think about them. We found female doctors face three primary obstacles in continuing their medical careers after motherhood. The child care support systems fail to provide adequate support 1) when the child is sick or in cases of emergency, 2) when the child enrolls in elementary school, and 3) with consideration for each doctor’s career plan. We suggest university medical courses include instruction on the child care support systems not only for female students but also for male students as well. Finally we argue child care support systems should be regarded as a whole hospital initiative.
