The aim of this research is to clarify how vacant spaces in Tomo district are distributed and how they have been utilized through accumulated changes. Those vacant spaces can be classified into nine types in terms of location, process, and users. Some vacant spaces are richly utilized by the surrounding neighbors without any relations of their owners. Such a common use is only found at the historical urban area, not at the landfill zone, and is likely to happen where residents have known each other before it becomes vacant.
