The aim of this paper is to clarify the forms of assembly of plural station squares in central Tokyo in terms of spatial compositions with surroundings. Initially, combinations of station squares around a station building are analyzed. Secondly, connections between those squares are analyzed through common elements such as passing streets and buildings which can be seen from several squares. Finally, 4 forms of assembly are clarified: unity of similar squares, one-sided integration of squares by building scale, connection of dissimilar squares with common railway tracks in canal bed, and indirect connection of squares with common distant high-rise building.
