> Tokyo is totally flat Tokyo is in no way even close to flat. It has some flat areas (e.g. landfill in Tokyo bay), but there are huge numbers of very hilly areas as well (including many popular commercial hubs and densely populated areas in the city center). Not gentle hills in many cases either, but quite steep. [... and if you go to the outskirts, there are actual mountains within the Tokyo city limits!] One difference with with SF, of course, is that Tokyo roads don't form a rigid grid that ignores the topography.... > Japan cities spend a lot more money on infrastructure than even American cities Tokyo mass transit is overwhelmingly private (owned, run, and financed), especially if you're talking about rail.
