Abstract
The purpose of this study is examining zoning system under Housing Master Plans within Tokyo Metropolitan Districts. Our analysis starts from a comparative approach of zoning system between inner Tokyo Wards and Tokyo Metropolitan Government, and it could be classified into three categories: they are commercial, residential and commercial-residential mixed zones. Then, we chose five areas from residential and commercial-residential mixed zones and had survey concerning housing locations. As a consequence, the differences of housing locations are found by horizontal and vertical ways, known as Gawa-An and floor levels, even in the same zone.
