If you want to ride the rails into Tokyo, you could find yourself cruising at 168 mph aboard a bullet train operated by East Japan Railway, better known as JR East. The company serves more than 15 million people daily and carries passengers on more than 7,400 km of track in the eastern half of the Japanese mainland, including the Tokyo area. JR East's Shinkansen (bullet-train) lines connect metropolitan Tokyo with other major cities. Besides its transportation-related operations, JR East generates revenue from leasing restaurant and retail space in its stations and from managing shopping centers and office buildings on property that has been developed near its stations.
