In this report we intend to illustlate the contents of the discourses concerning architectural design written by contemporary Japaneses architects, through investigating the articles in "SHINKENCHIKU" journal after world war II. From this point of view, we already reported several theses that clarify the contents of housing theories, urbanism, and desigh theories written by architects in the journal. In those theories, there are phrases expressing "Thoughts on Housing" "Thoughts on City" "Design Themes" "Spatial Conceptions" by architects. In the previous reports, such phrases are extracted, from each articles and their contents are compared with each other. This time we aim to illustlate the transition of the contents of architectural theories by contemporary Japanese architects, and the distinctive meanings of "Thoughts on Housing" "Thoughts on City", through synthetically investigating the results obtained in the previous reports.
