The purpose of this paper is to study by the hierarchical structure method with golden section for architectural elevations by Kenzo Tange. In case of many of his works of Kenzo Tange, people will find golden section on them. He requests his staffs to make models from the early stage of the design, and check the design and proportion quite repeatedly. Model makings are at the beginning in 1:500 scale, next in 1:200 scale, then in 1:50 scale , in 1:10 scale etc.. At each stages the. Frameworks of each scales are decided by him and by his old staffs. Therefore even if observers feel there is no les traces regulateurs or no modulor in the'design process in front of Kenzo Tange, golden section is gradually decided through the feed back process.
