Abstract
This paper aims to explore the innovation of planning techniques for utilizing old large vacant sites by examining the process of realizing the plans, in the case of the two old sites of Tokyo Metropolitan University surrounded by residential areas. In particular, our analysis focus attention on the reasons why the two contrasting results came out in the two old sites, one in Meguro Ward where realized plan followed the common consensus, and the other in Setagaya ward where the dispute continues between the high-rise condominium builder and residents. This paper also analyzes the roles of Tokyo Metropolitan Government and Setagaya government on the consultative process in the contrasting two cases. Our results clarified the importance of the two issues: 1) reconstruction of the role-sharing and the trust-building among the stakeholders, 2) encouraging participation of stakeholders in the consultative process to promote the application of their ideas.
