Jōetsu Shinkansen
Remove ads

The Jōetsu Shinkansen (上越新幹線) 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 Jōetsu 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

Summarize
Perspective

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.[5] Built at a cost of $6.3 billion,[6] it was built "to establish closer ties with Tokyo and promote regional development".[7]

Trial runs over the line began in November 1980, and regular service began on 15 November 1982.[8] 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 Ōmiya.

In September 1991, a 400 Series Shinkansen train set a Japanese rail speed record of 345 km/h (214 mph) on the Jōetsu Shinkansen line, and in December 1993, the STAR21 experimental train recorded 425 km/h (264 mph). The maximum speed for regular services on the line at the time was 245 km/h (150 mph) except for the section between Jomo-Kogen and Urasa which is 275 km/h (171 mph) for E2 series trains travelling towards Niigata. The urban section between Tokyo and Ueno is 110 km/h (70 mph), between Ōmiya and Ueno is 130 km/h (80 mph).[9][10]

The Basic Plan specifies that the Jōetsu Shinkansen should actually start from Shinjuku, which would necessitate building 30 km (19 mi) of additional Shinkansen track from Ōmiya. While some land acquisitions along the existing Saikyō Line were made, no construction ever started.[citation needed]

The entire line was upgraded to 275 km/h (171 mph), with construction starting in May 2019, and finished in 2023.[11] Upgrades included improvements to the soundproofing system.[12] This marks the first time that an E7 series train has operated commercially at more than 260 km/h (160 mph), 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 Jōetsu Shinkansen operate exclusively with E7 series trainsets and the travel time on the line is projected to be reduced by 7 minutes compared to the former E2 and E4 series trainsets.[12] The end of E2 series trainsets on Jōetsu Shinkansen services took take place on 17 March 2023 with the streamlining of all services to use the E7 series taking place the following day.[13]

Future plans

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.[14]
