After finishing the New York and Chicago maps I really wanted to go even bigger. That led me to my largest pixel map ever, Tokyo. The Tokyo subways system very large and complex. So much so there are actually two main networks. I had to stick with the most simplistic layout I could find that still allowed room for Mario graphics. I ended up using this map as a guide. That eliminated rivers and islands, but when you're working with 16 bits on and overworld map you have to make some compromises. Due to its complexity the free print is tablet paper sized (17" x 11"), but is still difficult to read.

Below is more of an up-close look. Full size prints are 9600 x 7200 pixels at 300ppi.
