Many densely built-up areas remain throughout Japan. Such areas have come to present difficulties from perspectives of disaster prevention. Therefore, their immediate development and improvement are necessary. Although uniform redesign such as widening and fireproofing has been implemented in many densely built-up areas, regional characteristics must be considered for planning. Therefore, this study was conducted to categorize densely built-up areas according to their locational and physical characteristics as a step toward redesign of densely built-up areas. Target areas were extracted according to their respective ratios of noncombustible area and building density. Categorizing produced several classifications according to locational and physical characteristics, revealing salient issues and redesign directions for the categories.
