What drives the seeming relentless dynamism of Tokyo? Is there something special about Japanese culture? Joe McReynolds, co-author of Emergent Tokyo, argues that the secret to Tokyo's energy and attractiveness as a place to live and visit comes from policies that allow Tokyo to emerge from the bottom up. Post-war black markets evolved into today's yokocho--dense clusters of micro-venues that turn over, specialize, and innovate nightly--while vertical zakkyo buildings stack dozens of tiny bars, eateries, and shops floor by floor, pulling street life upward. The engine? Friction-light rules: permissive mixed-use zoning, minimal licensing, and no minimum unit sizes let entrepreneurs launch fast and pivot faster. And surrounding this emergent urban landscape there's plenty of new housing with excellent transportation infrastructure to let ever-more people enjoy Tokyo's magic.
