This paper endeavors to describe the inter-personal environment of the exterior spaces around the super-highrise condominiums (SHC) developed in Tsukishima, Tokyo. In order to obtain the bonus volume by the relaxation treatment for the super-highrise buildings, each building is obliged to let their surrounding areas open to the public. In Japan, because of the eagerness to building volume, almost all the super-highrise buildings prepare these public open spaces. This describes the inter-personal environment by the combination of density of behavior observed in unit spaces and the percentage of the staying behavior in them through the behavior observation and mapping. We found that the characteristics of inter-personal environment of either small alley spaces, i.e. Roji, streets, parks, and open spaces around SHC are different from to each other, although that of open spaces of SHC resemble to that of the street. We also analyze the images of these outdoor spaces by users.
