Tokyo Travel Tip-Subway and Train map for SUICA

Just for kicks, here is a link to a pdf file that displays all of the subway and train lines that the SUICA can access. These include JR lines, private railway lines, and Tokyo Metro subway lines. The map may seem daunting and confusing but the infrastructure is extensive. However, I think that it illustrates how much Tokyoites rely on public transportation and a testament to how it can get you anywhere you want to go. I personally can vouch for the timeliness and efficiency of the system. Take to heart that not all stops are noted in the map
