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 Joetsu or the historical Jōetsu region, which instead are served by the Hokuriku Shinkansen.

- Although 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.
As of 2012, the maximum line speed is 110 km/h (70 mph) between Tokyo and Omiya, and 245 km/h (150 mph) between Omiya and Niigata. Additionally Tokyo bound trains have a higher limit of 275 km/h (170 mph) between Jōmō-Kōgen and Urasa. Like all Shinkansen lines, the Jōetsu Shinkansen is standard gauge.
As of October 2021[update], the following train types operate on Joetsu Shinkansen services.
- E2 series: Toki / Tanigawa (since January 2013)
- E7 series : Toki / Tanigawa (since March 3, 2019)
Between fiscal 2018 and 2020, eleven 12-car E7 series train sets are scheduled to be introduced on Joetsu Shinkansen services, replacing the E4 series trains, raising the speed from 240 km/h to 275 km/h.
Former rolling stock
- 200 series: Toki / Tanigawa (until March 2013)
- E1 series: Max Asahi / Max Toki / Max Tanigawa (until September 2012)
- E4 series: Max Toki / Max Tanigawa (until October 2021)
The entire line is currently being upgraded to 275 km/h, with construction starting in May 2019. The upgrades are scheduled to be completed by 2023.
This will mark the first time that an E7 series train has operated commercially at more than 260 km/h, which is the maximum speed of the only other line served by this train, the Hokuriku Shinkansen.
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 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 is 245 km/h (150 mph) except for the section between Jomo-Kogen and Urasa which is 275 km/h (170 mph) for E2 series trains travelling towards Niigata. The urban section between Tokyo and Ōmiya is 110 km/h (70 mph).
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.
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.
Special event train services

Also on 17 November 2012, a special Joetsu Shinkansen 30th Anniversary (上越新幹線開業30周年号, Jōetsu Shinkansen Kaigyō 30-shūnen-gō) 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.
