In recent years, the problem of “childcare anxiety” among Japanese women has not been effectively solved, but has become increasingly serious. This important issue, which is related to the health of mothers and children and the development of society, has been repeatedly presented in films and dramas. This article examines the issue of “childcare anxiety” among Japanese women from a gender perspective, using the Japanese drama The House on the Slope as an example, and discusses several structural causes. The first, social change has led to childcare isolation as one of the main causes of “childcare anxiety” among Japanese women. And the second, the unequal gender division of labour under patriarchy has overburdened Japanese women with childcare, which is also a major cause of “childcare anxiety”. The third, mentally oppressive view of motherhood has also contributed to women’s “childcare anxiety”. Therefore, the only way to solve the problem of “childcare anxiety” among Japanese women is to take appropriate measures to address the above three points.
