Shibuya Station, Tokyo: Every day, dusk gives way to a riot of color lighting up whole façades of high-rise buildings filled with department stores, funky boutiques, hair salons, noodle shops, theme-dècor bars, and restaurants. School kids, young adults, and plain-suited "salary men" (office workers) spill out of trains and buses, meet up with friends and fan out into the urban playground of the Japanese capital.
