This paper aims to analysis disorderly development and conversions of land use in the Urbanization Control Area (UCA) and recognize the influences of the designation of Urbanization Promotion Area (UPA) over the urban sprawl in UCA. The conclusions are as follows; 1) The urban sprawl in UCA is shown not in the three great metropolitan areas of Tokyo, Osaka and Nagoya, but in the suburbs of many local cities. 2) Three features are pointed between the urban sprawl and the designation of UP A. First, if the capacity of the UPA is too small to accommodate the large demand for land and housing, then many developments and buildings are generated in UCA. Second, in almost the all UCA the scale or the capacity of UPA has no direct influence over increase or decrease of urbanization activities in UCA. Third, however, the large population designated outside UPA generates a large quantity of urban sprawl, because almost all of their urbanization activities in UCA are permitted as exceptions to the development control systems. 3) As the development control system has exceptions and loopholes in UCA, it is not effective in legally restraining urban sprawl. 4) As there is in general no land use planning in UCA, urbanization activities are not controlled or induced. Consequently permit on urban sprawl or scatteration results.
