Abstract
Health consultation business that started as a social business in the 1920s was reformed by wartime welfare during the World War II. This reformation was expected to strengthen the childcare improvement guidance for mothers. Counselors instructed mothers to take care of their children thoroughly according to their own children’s characters; however, childcare practice with visit consultation did not actually change. To address this issue, new health consultation business supported by multidisciplinary cooperation among various areas of childcare workers who were entrusted each other was initiated at the Aiiku-Rinpokan Settlement. This was qualitatively different from cooperation based on shared responsibilities.
