Tokyo Wonder Site's Hongo Location exhibited work conducted by the University of Tokyo Sustainable Prototyping Lab. For the past five years, students have looked at how existing material and social flows within the city can be harnessed and rerouted to create sustainable architectures within the city. Much of the focus has been on how to couple new digital and fabrication techniques with the inherent material properties of waste products that the city produces in order to create new architectural and social conditions.
