Rail travel serves as a primary means of transportation in Japan. The Yokosuka Line, for example, spans 73 kilometers or 45 miles, originating in central Tokyo. International travelers can purchase a Japan Rail Pass, which provides quick and easy access to these efficient trains.

The Yokosuka Line, or Yokosuka-sen, was one of the first railways in Japan, built in 1889 to provide transportation to and from a strategic military base on the peninsula. Over the years, the line was extended to facilitate increased rail traffic – nearly 100,000 riders per day. Today, it not only relieves big-city congestion, but it provides travelers access Tokyo staples such as Tokyo Station?s Shinkansen bullet trains and the Yamanote Loop Line.
