Kokeigayosui Plaza, completed in 2016 in Tajimi, Gifu Prefecture, represents a thoughtful contemporary approach to public space design. Created by Onsite Keikaku Sekkei, this park and plaza project demonstrates careful attention to integrating historical water infrastructure with modern urban planning. Located in the Otowa district, the plaza serves as both a functional gathering space and a cultural landmark that honors the region's relationship with the historic Kokeigayosui waterway. The design successfully balances preservation of local heritage with contemporary landscape architecture principles, making it a noteworthy example of sensitive urban renewal for architecture enthusiasts interested in community-focused design solutions.
