In this study, the author attempts to elucidate the regional resources of day nurseries from the view point of the outdoor activities. The authors conducted the questionnaire survey to day nurseries in Yokohama City. The results showed that 70% of the authorized day nurseries had the outdoor activities more than once a week, and 84% of the Yokohama day nurseries had them almost every day. To compare with the authorized day nurseries, the Yokohama day nurseries had smaller play ground, and they always use regional resources. Moreover, most of the day nurseries use not only the parks but also the roads to childcare and education place corresponding to the childcare aim.
