I'd love to see one of these rose diagrams for Tokyo .. when I was there I found it very, very difficult to navigate even my local neighbourhoods, and remarked as much to my hosts - who explained to me that the reason Tokyo was laid out in what could only loosely be described as "chaotic crows feet on acid", is so as to make it very difficult for any invading armies to march directly into the city in a straight line - giving defenders lots of places to choke them off.
