The Tokyo Metro is intense!
The Tokyo Metro is intense! Everything is in Japanese, there are no maps that show all the lines, and there are so many different routes and lines that it's really confusing for a first-time visitor. However, after a few adventures you eventually get the hang of it and actually enjoy it. What's nice about the Tokyo Metro is that you can get to just about everywhere and most of the Japanese locals are very polite and helpful if you ever need to ask for directions. You'll probably end up doing this as the metro stations are huge...seriously, you could literally get lost in some of the bigger ones.
