Fascinating article. I love getting lost in Tokyo too. Here are a couple of tips I could add in case of Tokyo...

* All the TV antennas point at Tokyo Sky Tree.

* All the regional train tracks (except Yamanote) are radial. They're all going toward Yamanote Line.

* Major named streets (except "Kanjo" or circular streets) go to the Emperor Palace.

* Tokyo is a city carved by rivers, so it has many ups and downs. Pay attention to town names that are typically indicative of its configuration, e.g. -yama (mountain), -oka (hill), -tani/-gaya (valley), -saka (slope) etc.

* Beware of subway lines and subway exits because their shapes are very unpredictable, with confusing station names.
