The dynamism of Tokyo's commercial streets with diverse shopping building facades creates an attractive streetscape where buildings, people and public spaces converge at eye level. The urban environment generated by the wide sidewalks is considered an element involved in the quality of pedestrian-centered public spaces. This research aims to clarify the ephemeral aspects of the streetscape of Omotesando, focusing on the composite characteristics of building facades, outside spaces, sidewalks and pedestrian activities on the Street Surface. The findings suggest ephemerality in different levels of the patterns creating representative scenes in Omotesando.
