Shinjuku Station is a hub where numerous train and subway lines converge. More than 3 million people travel through this station each day, making it the busiest station on earth. It is just one hub station on the Yamanote Line, though. This loop route rings central Tokyo, surrounding an area serviced mainly by subways and serving as the hub for the spokes that head away from the center of the city. With all these lines to choose from - and more than 500 stations in the Tokyo region, more than other cities like Paris or New York - it's easy for first-time visitors (and even long-time residents) to get lost, so people generally carry a railway map or take constant glances at the charts displayed in the stations.
