Nozomi (train) in the context of "Shinagawa Station"

The Tōkaidō Shinkansen (Japanese: 東海道新幹線; lit. 'East coast route, new main line') is a Japanese high-speed rail line that is part of the nationwide Shinkansen network. Along with the San'yō Shinkansen, it forms a continuous high-speed railway through the Taiheiyō Belt, also known as the Tokaido corridor. Opening in 1964, running between Tokyo and Shin-Ōsaka, it was the world's first high-speed rail line, and it remains one of the world's busiest. Since 1987, it has been operated by the Central Japan Railway Company (JR Central), prior to that by Japanese National Railways (JNR).

There are three types of services on the line: from fastest to slowest, they are the limited-stop Nozomi, the semi-fast Hikari, and the all-stop Kodama. Many Nozomi and Hikari trains continue onward to the San'yō Shinkansen, going as far as Fukuoka's Hakata Station. The different services operate at mostly the same speed.

The San'yō Shinkansen (山陽新幹線) is a line of the Japanese Shinkansen high-speed rail network, connecting Shin-Osaka in Osaka with Hakata Station in Fukuoka, the two largest cities in western Japan. Operated by the West Japan Railway Company (JR West), it is a westward continuation of the Tōkaidō Shinkansen and also serves other major cities in between on Honshu and Kyushu islands such as Kobe, Himeji, Okayama, Hiroshima, and Kitakyushu, through the Shin-Kanmon Tunnel. The Kyushu Shinkansen continues south of Hakata to Kagoshima. The San'yō Shinkansen connects Hakata with Osaka in two and a half hours, with trains operating at a maximum speed of 300 km/h (186 mph) for most of the journey. Some Nozomi trains operate continuously on San'yō and Tōkaidō Shinkansen lines, connecting Tokyo and Hakata in five hours.

Hikari (ひかり; "Light") is a high-speed train service running on the Tōkaidō and San'yō Shinkansen "bullet train" lines in Japan. Slower than the premier Nozomi but faster than the all-stations Kodama, the Hikari is the fastest train service on the Tōkaidō and San'yō Shinkansen that can be used with the Japan Rail Pass, which is not valid for travel on the Nozomi or Mizuho trains except through a special supplementary ticket.

Kodama (こだま; "Echo") is one of the three train services running on the Tōkaidō and San'yō Shinkansen lines.Stopping at every station, the Kodama is the slowest Shinkansen service for trips between major cities such as Tokyo and Osaka. The Kodama trains are used primarily for travel to and from smaller cities such as Atami. Travelers between major cities generally take the Nozomi or Hikari services, which make fewer stops, although the Nozomi requires paying a supplement under the Japan Rail Pass while the Kodama does not, making these services an affordable alternative.
