The Tōkaidō Shinkansen (東海道新幹線) is a Japanese high-speed Shinkansen line, opened in 1964 between Tokyo and Shin-Ōsaka. Since 1987 it has been operated by the Central Japan Railway Company (JR Central), prior to that by Japanese National Railways (JNR). It is the oldest high-speed rail system in the world and one of the most heavily used.

- Nozomi: limited-stop services, since March 1992
- Hikari: semi-fast services
- Kodama: all-stations shuttle services
There are three types of trains on the line: from fastest to slowest, they are the Nozomi, Hikari, and Kodama. Many Nozomi and Hikari trains continue onward to the San'yō Shinkansen, going as far as Fukuoka's Hakata Station.
700 series and N700 series train sets operate on the line in any of the three service patterns. The Hikari run from Tokyo to Osaka took four hours in 1964; this was shortened to 3 hours 10 minutes in 1965. With the introduction of high-speed Nozomi service in 1992, the travel time was shortened to 2 hours 30 minutes. The introduction of N700 series trains in 2007 further reduced the Nozomi travel time to 2 hours 25 minutes. As of 14 March 2015[update], after a speed increase to 285 km/h (177 mph), the fastest Nozomi service now takes 2 hours 22 minutes from Tokyo to Shin-Osaka.
As of August 2008[update], Hikari services travel from Tokyo to Shin-Osaka in approximately 3 hours, with all-stopping Kodama services making the same run in about 4 hours.
Kodama trains stop at all stations. Nozomi and Hikari trains have varying stopping patterns (some Hikari trains stop at stations marked "▲"). All trains stop at Tokyo, Shinagawa, Shin-Yokohama, Nagoya, Kyoto, and Shin-Osaka.

The Tokaido Shinkansen line was originally conceived in 1940 as a 150 km/h (93 mph) dedicated railway between Tokyo and Shimonoseki, which would have been 50% faster than the fastest express train of the time. The beginning of World War II stalled the project in its early planning stages, although a few tunnels were dug that were later used in the Shinkansen route.
Construction of the line began on 20 April 1959 under JNR president Shinji Sogō and chief engineer Hideo Shima. It was completed in 1964, with the first train travelling from Tokyo to Shin-Osaka on 1 October 1964 at 210 km/h (130 mph). The opening was timed to coincide with the 1964 Summer Olympics in Tokyo, which had already brought international attention to the country. Originally, the line was called the New Tokaido Line in English. It is named after the Tokaido route of Japan, used for centuries. Speeds have been increased to 285 km/h (177 mph), except for lower limits applying between Tokyo and Shin-Yokohama and in densely populated urban areas around Nagoya, Kyoto and Shin-Osaka stations.
A new Shinkansen stop at Shinagawa Station opened in October 2003, accompanied by a major timetable change which increased the number of daily Nozomi services.
All Tōkaidō Shinkansen trains to and from Tokyo make station stops at Shinagawa and Shin-Yokohama. (Before March 2008, alternating Nozomi and Hikari services stopped at either or both of these stations.)
A new station, Minami-Biwako, was planned to open in 2012 between Maibara and Kyoto to allow a transfer to the Kusatsu Line. Construction started in May 2006, but in September 2006, the Ōtsu district court ruled that the ¥4.35 billion bond that Rittō city had issued to fund construction was illegal under the local finance law and had to be cancelled. The project was officially cancelled in October 2007.
From 1964 to 2012, the Tokaido Shinkansen line alone carried some 5.3 billion passengers. Ridership increased from 61,000 per day in 1964 to 391,000 per day in 2012. By 2016, the route was carrying 452,000 passengers per day on 365 daily services making it one of the busiest high speed lines in the world.

It was announced in June 2010 that a new shinkansen station in Samukawa, Kanagawa Prefecture was under consideration by JR Central. If constructed, the station would open after the new maglev service begins operations.
In December 2013, JR Central president Yoshiomi Yamada announced the operating company's intentions to raise the maximum line speed beyond 270 km/h (170 mph), with a revised timetable to be introduced in spring 2015. In February 2014, JR Central announced that, from spring 2015, the maximum speed would be increased to 285 km/h (177 mph) for services using N700A or modified N700 series trains. Initially, just one service per hour would run at 285 km/h (177 mph), with more services gradually added, as the older 700 series is phased out.
By May 2020, all 700 series train are planned to have been retired from service on the line, completing the transition to 285 km/h operation.
Shizuoka Prefecture has long lobbied JR Central for the construction of a station at Shizuoka Airport, which the line passes directly beneath. The railway has so far refused, citing the close distance to the neighbouring Shin-Fuji and Shizuoka stations. If constructed, travel time from the center of Tokyo to the airport would be comparable to that for Tokyo Narita Airport, enabling it to act as a third hub airport for the capital. This disagreement is seen as the primary reason why Shizuoka Prefecture has not yet authorised the construction of the new Chuo Shinkansen, part of which is planned to go through the prefecture. As the station would be built underneath an active airport, it is expected to open after the new maglev line.
