Nowadays, Japan has innumerable vacant houses, vacant lots, and deserted shopping streets whose owners are unknown and neglect them because of factors, such as the declining birthrate and aging population. A considerable expense and unprofitable aspect would lead developers to passive attitudes towards reconstruction, and thus they remain as negative legacies. I conducted hearings and workshops, targeting Hikone Ginza Shopping Street located in the southern part of Hikone Castle Town which was crowded as a core part for local residents at the time of its first development but is now just a monotonous path of vacant stores. From this research, I propose a role of gradual redevelopment through regeneration approaches including renovation and reduction.
