Abstract
Planning officials, researchers and practitioners are much concerned in urban restructuring and reorganizing city planning area caused by merger of municipalities. The planning activities are conditioned by the urban structure, therefore city planning area should be reorganized in conformity with restructured image of the merged municipality. Based on the case studies in Akita prefecture, this paper concludes the following ; 1) the urban structure is restructured as the decentralized-network urban core type, 2) for actualizing the urban structure, city planning area should extend for not only facilitating urban development but also restricting uncontrolled development.
