In this article we will trace the mechanism in which the locality has been generated as a result of personal mobility. Our material is the motivation structure of participants in the community welfare movement in Setagaya-City since the end of the 1990's. Geographical mobility has cut people off from the family-kinship relationships that have provided for welfare in the past and promoted the formation of the alternative welfare provision including public services, market, and friendship. Among those who have established stable residency meaning the ownership of a house and land, we find the locality as a concrete and practical alternative relationship to that of family and kinship. We term this pattern re-settlement. It represents the reality of urban life in an era when the dichotomy between village or traditional society and urban society has lost meaning.
