Another quick reflection from the Roland reading...and one I more or less agree with is the impossibility of finding one's way around Tokyo.
When I first moved to Tokyo from Kamakura I was shocked by quite a few things. The first of which was the total disconnect most people seem to have with distances and Train stations. When talking of the Tokkaido line, this is completely understandable, as it would take hours and hours to walk between stations. However, when I lived in Kamakura, I used the Enoden, which is a small train that even goes through the road at times. As such, the stations were rather close as well, and everyone knew it. There would sometimes be someone who would race the train on their bike, and sometimes even win.
However, in Tokyo, many times people think of the gulf between station as uncrossable. However, most are no more than a 20 minute walk away. On a bicycle, almost nothing. It sometimes seem that Tokyo tries to hide its true size by hiding behind a huge network of Subway and Train stops.

The other thing of course is what I did discover by just walking. Tokyo has more shops than one could hope to visit in a lifetime. I have been walking places, just to walk and see and discovered things I would have never found trying to go in a specific place. Parks in Industrial areas, Random Festivals, and shops selling anything one could ever want. It is of course true that to get anywhere quickly in Tokyo you almost have to have gone once to find it first. However, I definitely recommend just heading out one day.... you'll be surprised what you may find.
