Abstract
This case study is to clalify a developping process of a new participatory project of Kyoto City Office for renovating small playgrounds over a period of 3 years, and to investigate what structures of the public involve-ment program influence aspects of management. Participant numbers and other indexes of management conditions in 13 cases were analyzed. Our conclusions are; (1) scale of the numbers becomes larger from the first term to the second, by clarification of the level of the project goals and program steps, (2) specific aspects of PI programs, especially continuative discussion settings and various occasions for local people to participate in, are necessary.
