Tokyo Playground aims to investigate the leftover space produced when the infrastructure overlaps with the urban tissue and to highlight how these are metabolized, then transformed into meaningful public spaces. The "hybridization" of Tokyo is examined using three references as a starting point. First is the spatial typology of sakariba that transformed what were transitional zones into pleasure districts during the Edo period, creating what was arguably the most definitive type of collective space for citizens of Edo. The second reference is Roland Barthes' description of the infrastructuraI experience. Thirdly, the book Made in Tokyo illustrated the strong mutual dependence among infrastructure, architecture, and the city as a unique characteristic of Tokyo. Transit space can be reused on the human scale with different programs related to time for pleasurable activities. Tokyo Playground aims to capture the idea of emotional space within infrastructure. It aims to highlight some possible design strategies and tools that help to domesticate the infrastructure through the injection of pleasure and playful programs with an understanding of how humans experience, occupy, and interpret such spaces. Leftovers within the infrastructure are opportunities for social and ecological reuse and these precious voids contribute to creating the contemporary soul of the city as it becomes the source of vibrant energy for transcultural urban regeneration. 展开更多
