in social communication and social interaction across multiple contexts, and (B) Restricted, repetitive patterns
of behavior, interests, or activities. In Japan, most of the preschool children with ASD attend child development
support facilities. While many studies have revealed the effectiveness of designing environments on supporting
children with ASD, it is not understood what outdoor play environments is needed to support them at the child
development support facilities. To examine that, this study conducted literature review focused on findings
which applicable to design those facilities. As the result, it is important to design with consideration for the
problems of sensory issues, the difficulty of prediction, compared with the difficulties of social communication
and social interaction. Also, it is needed to design with understanding play features of children with ASD such
as their concentration on their favorite play, their own purposes on their play. As the issue in the future, it
is needed to reveal the reality of (1) how children with ASD play and (2) how the staff support them at the
