This paper analyzes the effect of various urban development projects on the open spaces environment on the fringe of Tokyo Ward areas that were once designated as green districts in 1948-1969 and presents some proposals for green open space policies. The history of policies on parks and open spaces in Tokyo was divided into three periods from the viewpoint of urbanization. Based on previous urban development and open space policies, target areas are categorized into eight types. A study based on a survey on each type's open space environment revealed the following three points: 1) The stringent building restrictions pertaining to green districts and subsequent well-planned development projects in the rapid urbanization period helped making many green open spaces in the present built-up area. 2) The stringent building restrictions pertaining to planned parks by the city planning law are not enough to keep green open spaces. 3) Categorization based on the historical process of urbanization policies is useful for parks and open space control, especially for urban redevelopment areas.
