Recently, the increase of underused land such as outdoor parking lots and vacant area has been a serious problem in the central area of local city. However, secular change of underused land has not been clarified on a nationwide scale. In this study, we constructed the data of underused land using house map on GIS to understand the change of distribution and land use regarding underused land in the central areas of 37 cities at 3 point in time. Result showed that, total area of underused land was increased in recent years. And, underused land area per lot became large in cities where underused land area was decreased from 1995 to 2005. Then, underused land is distributed close to each other. In addition, the change of distribution depended on whether underused land has been increased or decreased. Lastly, integration of underused land is important when it is utilized. Keywords: Underused Land, Central Area of Local City, Land Use Change, House Map, GIS
