Abstract
Over the past two decades, the vertical urban space has brought some crucial changes in the utilization of spaces in the center of Tokyo. One of such changes reflects the increase of high-rise buildings mainly composed of office spaces. We can commonly observe that there have been some distinct spatial utilization patterns at different floors and that the land-ownership structure has profoundly changed the urban morphology under this revitalization process. This paper examines the potential of land-ownership due to urban changes by exploring both spatial utilization and property transfer in the center of Tokyo.
