This study was intended to find conditions required for promoting the city-planning on the initiative of residents, by clarifying the developmental processes in the citizen-led city-planning in Kanaoka-cho, Sakai City, which is located in an urban fringe area. According to our analysis of the results, the city-planning activities were found to be categorized into five stages: 1. the primary period of proposition initiated by residents, 2. the period of recognizing and sharing the problems of the local community, 3. the period of determining principles on the city-planning, 4. the period of making a vision on the land use, and 5. the period of setting about the specific activity. It is also revealed that in order to promote the progress in each phase, it is necessary to recognize and share the problems, and to improve the community organization as a decision-making body making an agreement with the principles or the vision. And also it is important to connect closely with administrative bodies or universities that give them technical advice appropriately.
