This paper studies the changes and effects of open space policies mainly based on the Capital Region Improvement Act enacted in 1956. In the basic plan under the act, the National Capital Region was divided into 3 areas that are the Built-up Area, the Suburban Area,and the Urban development Area. A study based on a survey on different open space policies in each area revealed the following four points: 1) In most of 3 areas, zone restrictions and vacancy regulation areas were designated in order to control open space around the capital region. 2) In 'The comprehensive city plan of 3tama area' planned in 1958, the purpose of the Suburban Area changed from building green belt to develop residential cities. 3) In Urban development area, intensive financial supports of government for improving urban infrastructure promoted building many small parks. 4) Forests in suburban green zone preservation area have been preserved by designated the urbanization-restricted area under the revised city planning law in 1970.
