Omotesando Avenue, which is the symbolic approach to Meiji Shrine, but also has the characteristics of a wide urban road lined with zelkova trees, was part of Tokyos city planning projects during the Taisho Period.The primary resources of this study were the review of the context of its formation using documents on the development of Meiji Shrine, documents on the development of roads in the city of Tokyo, and Tokyo City Planning Committee conference minutes.Further, the relationship between the concept of street trees and that of trees lining shrine approaches were considered using specialist journals of the time.Through the conference discussion and the design changes, it is clear that the unusually wide sidewalks and trees were provided for the great number of visitors to the shrine.The zelkova trees were regarded to be an appropriate choice for such shrine approaches and were also considered to be representative of the Kanto landscape.Therefore, while an increased use of the automobile and local military activities of the time were also considered, the traditional notion of shrine approaches contributed to the formation of the resulting modern boulevard.
