Abstract
This paper aims to investigate decision-making process on the machizukuri system of project type collaborative planning, and to clarify the point at issue of the decision-making. Machizukuri plays very important role, because of the diversification of the citizens needs and the dissatisfaction of an administrative resource. In that field, the collaborative planning has increased, that the administration and the citizens appropriately allot the role and they work on the problem solution cooperatively. The collaborative planning was optional policy for the municipalities, but now contents of the machizukuri are abundant quantitatively and qualitatively, so some advanced municipalities are working on the institutionalization.
