Tokyo is a large and sprawling city, but is home to one of the best public transportation systems in the world—clean, on-time and efficient. By far the easiest way to get around is on the trains and subways. If you’re not used to taking public transportation at home, don’t worry! Many signs in Tokyo will be in English. A prepaid Suica card is the easiest way to pay for your tickets, and you can buy one (or top it off) at any ticket machine in the Japan Rail stations.
