Jōetsu Shinkansen

The is a high-speed shinkansen railway line connecting Tokyo and Niigata, Japan, via the Tōhoku Shinkansen, operated by the East Japan Railway Company (JR East). Despite its name, the line does not pass through the city of Joetsu or the historical Jōetsu region, which instead are served by the Hokuriku Shinkansen. The name instead originates from the parallel Jōetsu Line, which in turn is named after the two provinces that it connects: Jōshū (an alternate name for Kōzuke Province which comprises today's Gunma Prefecture), and Echigo Province (modern day Niigata Prefecture).

History

The program to build the new line was initiated in 1971 by Niigata-born prime minister Tanaka Kakuei; one popular anecdote is that Tanaka determined the line's routing by drawing it on a map with a red pencil. Built at a cost of $6.3 billion, it was built "to establish closer ties with Tokyo and promote regional development".

Trial runs over the line began in November 1980, and regular service began on 15 November 1982. The line was initially planned to terminate at Shinjuku Station, but economic considerations pushed Japanese National Railways (JNR) to merge the line with the existing Tōhoku Shinkansen line at .

In September 1991, a 400 Series Shinkansen train set a Japanese rail speed record of on the Jōetsu Shinkansen line, and in December 1993, the STAR21 experimental train recorded . The maximum speed for regular services on the line is except for the section between Jomo-Kogen and Urasa which is for E2 series trains travelling towards Niigata. The urban section between Tokyo and Ōmiya is .

The Basic Plan specifies that the Jōetsu Shinkansen should actually start from Shinjuku, which would necessitate building of additional Shinkansen track from Ōmiya. While some land acquisitions along the existing Saikyō Line were made, no construction ever started.

The Niigata prefectural government has proposed building a new multi-modal terminal to directly connect the Shinkansen to the port of Niigata, potentially allowing direct transfers to ferries and cruise ships, and to potentially allow direct access between the Shinkansen and Niigata Airport. However this plan is foreseen to be completed only by the mid-2040s.

Future plans

The entire line is currently being upgraded to , with construction starting in May 2019. The upgrades are scheduled to be completed by 2023. Upgrades included improvements to the soundproofing system. This will mark the first time that an E7 series train has operated commercially at more than , which is the maximum speed of the only other line served by this train, the Hokuriku Shinkansen. As a result of the upgrades, all trainsets on the Joetsu Shinkansen will operate exclusively with E7 series trainsets and the travel time on the line is projected to be reduced by 7 minutes. The end of E2 series trainsets on Joetsu Shinkansen services is scheduled to take place on 18 March 2023, which is also the date of the implementation for the operating speed improvements.

Special event train services

On 17 November 2012, a special service ran as ''Toki'' 395 from Omiya to Niigata using 10-car 200 series set K47.

Also on 17 November 2012, a special service ran from Niigata to Tokyo using E5 series set U8, with a special ceremony at Niigata Station before departure. This was the first revenue-earning service operated on the Joetsu Shinkansen by an E5 series trainset.
