Shinkansen

The Shinkansen (Japanese: 新幹線; [ɕiŋkaꜜɰ̃seɴ] , lit. 'new main line'), colloquially known in English as the bullet train, is a network of high-speed railway lines in Japan. The system was developed to provide connections between Tokyo and other regions of the country. In addition to long-distance services, some sections in and around the largest metropolitan areas are used for commuter travel. The first line, the Tōkaidō Shinkansen, opened shortly before the 1964 Tokyo Summer Olympics, the 552.6-kilometre (343.4 mi) route connects Tōkyō, Yokohama, Nagoya, and Ōsaka, the four largest cities in Japan.
