Recently, in Japan, Certified Childcare Centers (CCC) that has a mix of Type 1 certified children (educational use children) and Type 2 certified children (childcare use children) with different attendance periods and hours were increasing nationwide. Therefore, we consider that examining the differences in educational realities between Type 1 and 2 certification from health realities such as lifestyle habits, is a important research question in the field of our study field. Based on the above, this study examined the differences in lifestyle habits between children who were certified as Type 1 and 2 at CCC in light of Canadian 24-hour Movement Guidelines. The subjects in this study were 129 children (5 year olds) enrolled in three CCC in O City and K City, O Prefecture. The analysis used data from 89 subjects for whom all data was complete. Data was collected including actual physical activity measurements and questionnaire data on sleep and screen time in present study. All measurements and surveys were conducted between February and March 2021. As the results, no significant differences were found between the two types of children in terms of physical activity time or intensity, but there were confirmed that Type 2 children had less sleep duration and Type 1 children had more screen time. From the above facts, it was deemed necessary to present the results of this research to CCC and parents, share them with them, and then create practices aimed at improving lifestyle habits according to the type of use. It was also considered that the creation of 24-hour behaviour guidelines that were line with the culture and systems of Japanese children was an urgent task.
