The purpose of this paper is to study by the urban axis concept and the hierarchical structure method for the city design plans by Kenzo Tange. In case of many of his architectural works by Kenzo Tange, people will find golden sections on their design. From the early period of his design his architecture were a kind of city design and he strongly requests the urban axis concept to the symbolic structure design on top of the axis. In case of city design models his view points are like a birds eye view, so that his interests are relationship and proportion of combination of street width especially the case the streets are straight or orthogonally. Compare with architectural elevations, the functional restricts are stronger because the width of streets reflects the volume of traffic, but in case of symbolic loads landscaping with street trees etc. and with pedestrian way would control the total width of street. On the top of the urban axix he set the symbolic end and also symbolize the urban axis in case of the city design.
