It aims to clarify why public space has a close relationship with urbanization and urban regeneration, and why compact and diverse urban public spaces can promote public life.Design/methodology/approachFirstly, this paper investigated urbanization and urban renaissance in Tokyo, and analyzed the motivation for implementing UPSR from the perspective of urban policy. By on-the-spot investigations and literature materials, this paper introduced urban regeneration measures of Roppongi Hills to Toranomon Hills, and then summarized the similarities and differences between Roppongi Hills and Toranomon Hills by studying them on the basis of contrast.FindingsUPSR had been an important component of the re-urbanization process and an essential method of strengthening urban vitality. Moreover, it promotes the development of polycentric urban structure and the return of population to urban center. First, the UPSR pattern integrating vertical space and street space can form a net-shaped urban life circle. Second, more diversified public activities can serve more varied groups of people.Originality/valueThis paper systematically analyzes the development reasons and process of UPSR project in Tokyo from both internal and external factors, and summarizes the future development direction of public space through the comparison of the two projects, and provides a reference for urban public space renewal in the future.
