For a project to plan a street full of Tokyoʼs famous stores, the design brief was set to create “New Yokocho (Japanese alleyways packed with izakayas, bars and eateries)/street as social spaces”. The focus was on bringing out not limited to charms of the individual stores, but also charms of them as a gathering. “A mechanism of hopping stores” and “fun street“ that makes it achievable were set as cores of the proposal to build a Yokocho. By treating the building frame itself as a site and creating 26 small buildings with different roof heights, alleyways and open spaces were generated. The passage widths were narrowed down to 1.6m, and “hopping bar” has installed for each store alongside of the passages. The storesʼ outer walls are set back for 600mm from the actual lease outline so that spaces under the eaves and part of the streets could be used for people to gather. The intention was to design not just limited to depths and heights of bar counters, but also daringly design a variation of experiences even to narrowness and inconveniences by controlling detailed dimensions. As a result, instead of designing superficially, the project pursue possibilities in how design would function as “a system that induces rich experiences” in a fun street where smells, sounds and laughter ooze out.
