Maintaining all residential areas per current population size is remarkably tricky in a depopulation. As seen in urban shrinkage and perforation, a shift to an appropriate urban scale is necessary. This study focused on workplaces adjacent to residential areas, which we defined as AD-W, to explore the possibility of acquiring centrality for future urban compactness regarding the polycentricity context. In this paper, we used several statistical surveys and analysis of human flow data by GPS. We then identified the characteristics of residential areas and workplaces and considered the residential distribution of people commuting to these workplaces. The current set of AD-W and neighboring NT is not a compact city in terms of job and residential proximity. However, with AD-W taking on the role of the workplace in areas located in the hinterland, it appears that a relatively compact commuting area is being formed within the conurbation rather than commuting from the outer edges of the conurbation to the central urban areas as has been the case in the past. Furthermore, AD-W has the potential to gradually transform itself into one of the core polycentric cities, mainly located in the conurbation periphery in the future.
