This paper studies the changes and the actual conditions of the landscape conservation policies in the Tokyo 9hills tracts (Sayama, Kaji, Nagabuchi, Itsukaichi, Kasumi, The 1st Hachioji, The 2nd Hachioji, The north Tama, and The south Tama). On the basis of the studies of historical open space policies and existing green space distribution in each hill using GIS, the following points were revealed; 1)The measures of the open space policies in 9hills have changed according to the demands of the times. The history of the policies was divided into 4 epochs in terms of their concept. 2) The main policy concepts now are the system of vegetation management, usage of parks in hills, and zoning of conservation area. 3) For preserving green open space in hills, the permitting systems of development action based on the City Planning Act were much more effective than the notification systems of them.
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.

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 types open space environment revealed the following three points: (1) The strin...
The purpose of this paper is to analyze the impact of improving urban infrastructure and the park policies on the green open spaces in Tokyo Metropolitan suburban area after the establishment of the new city planning law in 1968. The research areas were designated as 'the Land Readjustment Assumed District' in 1965-1969. The following 3 points were clarified. 1) The policy of infrastructure improvement has been changing in different way from wards depends on the old infrastructure and the green open spaces. 2) After 1960s many small-sized parks were built by land readjustment projects. But most of the large parks over 10hectares planned before 1960s have still large uncompleted areas. With improving urban infrastructure, to build these large parks are important issue. 3) Some new district plans are formulating by each ward based on the guideline after 2004, but they are not enough from a standpoint of preserving and creating parks and open spaces.

The purpose of this paper is to analyze the history of the planning concept of City Planning Parks in Tokyo through the case study of Shinozaki Park. The following 4 points were clarified. 1) The planning concept of Shinozaki Park varies in times, such as prevention of urban expansion, homeland defense, buffer green belt for city planning road, and regional park. 2) The planning area of Shinozaki Park has been decreased by the urbanization pressure since 1960's. The local issues were given the priority over the large-scale issues at that time. 3) Between 1930's and 1950's, the planning conc...

The purpose of this study is to investigate how to solve the urban heat island problem in central Tokyo by appropriate greenerization. To estimate the effect of the existing green spaces and proposed greening plans on the urban heat island in Tokyo area(30km × 36km), the distributions of air temperature at 14:00 and 21:00 on typical summer day of eleven cases were calculated by using a numerical simulation with a mesoscale climate model. Then, the cost-effectiveness of two typical cases was calculated. The following results were obtained, 1) The air temperature increases at maximum 0.66℃ at...
