Abstract
Eika Takayama is one of the pioneers of city planning studies in Japan. However his academic achievements had never been recognized. This paper clarified the tracks of the Eika Takayama's academic approach for city planning before his famous academic article "Toshi-Keikaku no Houho ni tsuite (On methods of city planning)". He studied housing, standards of popular dwellings and neighborhood units in particular at first. Then, he started to study theories of city-scale planning by using the concept of "density" based on his experiences of housing studies, in order to develop the Tokyo remodeling plan during the war. After the war, he worked out the some methods of city planning based on combinations of "density", "arrangement" and "movement".
