Societies have understood and approached the commons from many different point of views that have shaped our cities for centuries. The ʻʻjuristʼʼ point of view can be simply described as looking at the urban realm in two main areas, the private and the public, which work together and perceive the commons as by-products of their relationship. This approach degrades the importance and value of the commons (resources). On the other hand, an entropy perceives the commons (resources) as the foundation of society, followed by the public and then by the private. Therefore, in our proposal we are unlocking this resource and use it as the basic element that will influence both the public and the private, and not the other way around, as in the juristʼs point of view. Due to the limited use, the river is underutilized which gives a private distinctiveness. In the case of Shibuya River, there are important questions to ask one selves. What is the reason of the current bad shape of the river? And in what way should the natural resource be limited to ensure a long-term viability for the city? The plan is to revitalize and unlock Shibuya River.
