This understanding of neighborhoods with respect to geographical spaces needs to be reconsidered, especially in the Tokyo Metropolitan center, where many high-rise buildings have been constructed owing to the extremely high land-value tax. Following the land and housing bubble in the beginning of the 1990s, Japan has experienced a decline in its economy. Over the past two decades, however, the vertical urban space has brought some crucial changes in the utilization of spaces in the city center. One of such changes reflects the increase of high-rise buildings mainly composed of office spaces. The upper floors of large buildings in this area have changed into simple but high-functional offices, while the lower floors have been predominantly utilized for commercial uses. We can also find small residential spaces in the upper floors of the buildings in the center. Mixed-use buildings have replaced the simple combination of residential and commercial uses in wooden houses. Since WWII, most residents have been operating small shops or restaurants on the lower floors and living on the upper floors in the same buildings. 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.英語フィールド
