The thing is that Tokyo has no city center. The actual center is the Emperor's palace, which is mostly empty and not accessible to the public. Other than that, each ward has its own downtown, its own suburbs. It really feels like Tokyo is not a city at all but a place where different cities decided to stick together, and administratively, it is. Shinjuku would be closest to a capital but not everything centers around it, in fact, it is not even where the "Tokyo" station is.
