Two services currently operate on the route: the limited-stop Toki, which runs the length of the corridor, and the all-stops Tanigawa, which runs between Tokyo and Echigo-Yuzawa Station. During the winter, Tanigawa trains continue via the Gala-Yuzawa Line, a 1.8-kilometre (1.1mi) branch line to serve Gala-Yuzawa Station and its adjoining ski resort, which is also owned by JR East. The branch line was originally built to store trains terminating at and departing from Echigo-Yuzawa.
As of 2023[update], the maximum line speed is 275 kilometres per hour (171mph). The fastest services cover the 269.5 kilometres (167.5mi) between Tokyo and Niigata in 90 minutes.
Train services
The Jōetsu Shinkansen operates with two different services:
12Although the official terminus of the Ryōmō Line is at Shin-Maebashi and that of the Agatsuma Line is at Shibukawa, trains on both lines run through to Takasaki.
↑Although the official terminus of the Joetsu Line is at Miyauchi, trains on the line run through to Nagaoka.
↑Although the official terminus of the Ban'etsu West Line is at Niitsu, most trains on the line run through to Niigata.
Rolling stock
As of 18March2023[update] the following train types operate on Jōetsu Shinkansen services.
Between fiscal 2018 and 2020, eleven 12-car E7 series train sets were introduced on Jōetsu Shinkansen services, replacing the E4 series trains,[2] raising the speed from 240km/h (150mph) to 275km/h (171mph).[3] Additional sets were gradually introduced through 2023 for the replacement of E2 series trains.

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.[6] Built at a cost of $6.3 billion,[7] it was built "to establish closer ties with Tokyo and promote regional development".[8]
Trial runs over the line began in November 1980, and regular service began on 15 November 1982.[9] 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 345km/h (214mph) on the Jōetsu Shinkansen line, and in December 1993, the STAR21 experimental train recorded 425km/h (264mph). The maximum speed for regular services on the line at the time was 245km/h (150mph) except for the section between Jomo-Kogen and Urasa which is 275km/h (171mph) for E2 series trains travelling towards Niigata. The urban section between Tokyo and Ueno is 110km/h (70mph), between Ōmiya and Ueno is 130km/h (80mph).[10][11]
The Basic Plan specifies that the Jōetsu Shinkansen should actually start from Shinjuku, which would necessitate building 30km (19mi) 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 275km/h (171mph), with construction starting in May 2019, and finished in 2023.[12] Upgrades included improvements to the soundproofing system.[13] This marks the first time that an E7 series train has operated commercially at more than 260km/h (160mph), 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.[13] 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.[14]
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.[15]
