This is because the station names of the former City Trams Higashiyama Line and the names of the bus stops of the City Bus became generalized in many cases (although some have now been changed), and as a result the word 'Higashi-oji' is not basically used for the names of the intersections, but instead the word 'Higashiyama,' from the alias of the street Higashiyama-dori Street, is used.
かつての市電東山線の駅や市バスのバス停の名称（現在は変更されているものもある）が一般化している事例が多いためであり、まず基本的に「東大路」を冠さず、別名の東山通から「東山」を冠する。
