Abstract
This paper aims to clarify relationship between festival space and street space by analysis of urban morphology in the case of Japan's three biggest float festivals.
Findings are as follows: 1) streets along float routes are selected to wider one for safety, 2) in the festival space on float moving, space to watch and space to move are separeted clearly as widths of streets along float route broaden, 3) in the festival space on float dragged around, there are two way in which floats are dragged around, along the center of the road and along the edge of the road, 4) sometimes floats are dragged around by not only widths of streets but also positional relationship of floats and the shrine.
