Abstract
The city consists of the workshops of citizens and their residences. So, the key factor for the urban renewal planning must be the problems between the place of workshops and residences. However, urban and housing policy in Japan, ignoring that key factor, has been mainly the development of Bed-Town in suburbs and re-development of C.B.D. for commuter's class group only. As a result, commuter's class group suffer from the long distance riding, and on the other side, working-class group and small managers group suffer from the aggravation of life environment such as overcrowdings and public nuisance. In a word, Metropolitan Area is going forward to crisis, step by step. So, the writer, studying on commuting life in urban areas, proves that the resident in urban areas are divided into 2 classes-"WGSLR" such as lower working class group, small managers group, and craftsman group, etc., or "Commuter's class group" and that "WGSLR" is specialized in Down Town areas. And so on, the writer ventures to propose that the key factor for the urban renewal planning must be "WGSLR" rather than commuter's class group.
