In the 1960s, many municipalities set up children's playground because of the high number of traffic accidents in which children playing on the road were victims. Amagasaki city, the study site, also established children's playground （Kodomo Hiroba）to prevent children's accidents. This project was started in 1968. There were 216 children's playground in the city as of 2017. One of the characteristics of these playground is that the municipalities set the outline for their installation and proceeded with the installation. Therefore, the project can be developed in accordance with the actual situation of the municipality.
The purposes of this study are to clarify the outline and transformation of the projects for establishing children's playground in Amagasaki City by organizing the project policies and actual conditions of the development of children's playground and to exam the characteristics and policy significance of the projects
Amagasaki city at the time of the project is the lack of land for parks due to geographical and social conditions. Therefore, it was difficult to establish a city park.
Through the research, following were identified. First of all, it is about the project of installing Children’s playground.1) Amagasaki city set up a variety of ways to secure children's playground quickly and in large numbers. The children's playground was set up in three ways: (1) the installation of children's playground on low or unused land (2) the installation of children's playground in the corner of the playground equipment that had already been installed (3) Entrusting the installation to a private operator. As a result, many playgrounds of different characteristics in different locations and areas were established in the city. 2)The installation was entrusted to the private sector. Around 1980, children's playground was shifted from the " Neighborhood type" (where the city leased land to the owner of the land and set up the playground) to the "apartment type" (where the private sector set up the playground at the time of development). 3) There was no reasonable standard to evaluate the projects established in children's playground when the project was reviewed. Amagasaki City explains that the reason for their abolition is that few people use children’s playground by a decrease in the youth population. However, block parks are used on a daily basis by a wide range of age groups, and so are the playground. The decision to review the project of the children's playground on such weak grounds is not reasonable.
In addition to the above, the characteristic of the project for children's playground in Amagasaki city is that it was established on low and unused land obtained in cooperation with various sectors. The policy significance of the project to establish children's playground in Amagasaki City provided citizens with a variety of options for places to relax by constructing. Children's playground is not only served as a complement to city parks for residents in areas where city parks are not yet established, but also as a place of relaxation for residents in areas where city parks have been established.
