With a lot of cities I've been to the public transit usually isn't too hard to figure out. It’s normally run by one company with a handful of lines, with a few exceptions. Not the case at all with Tokyo, Japan. It has one befitting the world’s largest metropolis. It’s massive, complicated and busy. I often say that the Tokyo subway map looks like someone just threw spaghetti at a wall and called it a day. I’m going to give you a quick ‘n dirty rundown of what you need to know to make your way around the city. Well, as quick as I can make it.
