The authors regard a children's hall as community play space where a play leader is stationed. This study aims at clarifying the actual use of these facilities and the relation between children and their play leader. The authors selected three children's halls in Kobe and conducted questionnaire researches on the children who visited the halls. The findings are as follows : 1) Half of the children visit the hall as often as more than twice a week. Some make no arrangements with friends; they visit the hall of their own accord. Most come to play with friends or take part in various events offered by the play leader. 2) Children regard the hall as an attractive place. They get to meet their playmates; a rich variety of plays is offered there : and new plays are introduced by the play leader. 3) The relationship between children and the play leader mainly depends upon how much children approach the play leader. Frequent visitors have stronger ties with the play leader. It should be pointed out that visitors need a play leader who is willingly to be involved with children's play while supporting their activities. 4) The children's halls should make more efforts to approach the children in the community, and the play leader's role should be strengthened, in order to make the hall as play base that children would want to visit and have a nice opportunity.
