Abstract
According to industrial structure change, there are many vacant lots in suburb industrial estates of local municipalities. The revisions to three Machizukuri law are intended to strict newly developments of large commercial facilities in suburbs, but many vacant lots in such estates may water down the revision, since many of these lots are designated as zones where commercial facilities can be developed. This paper aims to investigate large-scale commercial developments in such estates and to point out land use planning issue. It studies a case of Tochigi prefecture and finds out that there are 2 estates with commercial facilities. In each estate, zoning has been changed to attract facilities and amount of commercial area is as big as that of downtown. These developments are necessary to fill lots, but their location should be examined carefully regarding downtown invigoration policy and commercial structure.
