In this paper, we analyzed the children's play during recess in a elementary school, at especially courtyard on the examination from the one-year. The thermal environment of courtyard is different from the environment of playground by the materials of ground and the influence of sunlight reflected by the surrounding walls. And courtyard is the important place for outdoor playground taken place with school ground for lower classes' children. Moreover, we clarified courtyard is the really interesting playground in the point of interchanges between different age children and diversity of kind of play. Play at courtyard is related with air temperature, sunshine and wind velocity, especially wind over 2m/s disturbs play in all seasons. So we need to hold strong wind in planning for courtyard. And we found children select between shine or shadow at courtyard. So it's important to layout properly sun and shadow area at courtyard.
