Determining the boundary within which community facilities are generated under the influence of shopping centers is expected to reveal basic data for planning of attractive planned communities with the adequate mixed land use. In this study, we aimed to clarify how community facilities are generated around a new shopping center in a built-up area. The influential boundary and/or influential factors are concluded in our former papers, which are population, land use zones, location of nearest railway station, and distance from the shopping center. However, in this paper, the authors investigated the relationships between new shopping centers and their nearest railway station considering the distance between them, the size of the shopping centers, and generation of community facilities around the shopping centers. The conclusions derived from this investigation are as follows: (1) The densities of community facilities around each shopping center are classified into four categories according to the size of the shopping center and the distance from the nearest railway station. (2) Some shops or services not available in the shopping centers are found near the entrances of the shopping centers.
