In this study, we clarified how the quality of childcare at preschool childcare facilities (kindergartens, nursery schools, certified children’s kindergartens ) in the city is affected by the implementation status of the “Higashi-Hiroshima City Early Childhood Education and Childcare Action Plan.” The Action Plan includes, (1) the creation of an attractive childcare environment that nurtures the five abilities, (2) the promotion of natural childcare, (3) the enhancement of public childcare, and (4) the training and collaboration of childcare coordinators. Specifically, first, we clarified how teachers played a role in the growth of children from 0 years to preschool age through the implementation of the Higashi-Hiroshima City Early Childhood Education and Childcare Action Plan; second, we also evaluated parental childcare.
