Shinkansen#Service names

{{Nihongo|Shinkansen|新幹線}} in Japanese means 'new trunk line' or 'new main line', but this word is used to describe both the railway lines the trains run on and the trains themselves.{{Cite encyclopedia |url=http://www.lexico.com/definition/Shinkansen |archive-url=https://web.archive.org/web/20200322182255/https://www.lexico.com/definition/shinkansen |archive-date=2020-03-22 |title=Shinkansen |dictionary=Lexico UK English Dictionary |publisher=Oxford University Press}}{{Cite web |date=2014-11-12 |title=The Shinkansen Japan's High-Speed Rail Is Full of Miracles |url=https://www.japan.go.jp/tomodachi/2014/autumn2014/the_shinkansen_japans_high-speed_rail.html |access-date=2024-11-21 |website=The Government of Japan - JapanGov |language=en}} In English, the trains are also known as the bullet train.

Japan was the first country to build dedicated railway lines for high-speed travel. Because of the mountainous terrain, the existing network consisted of {{RailGauge|1067mm|lk=on}} narrow-gauge lines, which generally took indirect routes and could not be adapted to higher speeds due to technical limitations of narrow-gauge rail. For example, if a standard-gauge rail has a curve with a maximum speed of {{convert|145|km/h|mph|abbr=on}}, the same curve on narrow-gauge rail will have a maximum allowable speed of {{convert|130|km/h|mph|abbr=on}}. Consequently, Japan had a greater need for new high-speed lines than countries where the existing standard-gauge or broad-gauge rail system had more upgrade potential.

Among the key people credited with the construction of the first Shinkansen are Hideo Shima, the Chief Engineer, and Shinji Sogō, the first President of Japanese National Railways (JNR) who managed to persuade politicians to back the plan. Other significant people responsible for its technical development were Tadanao Miki, Tadashi Matsudaira, and Hajime Kawanabe based at the Railway Technical Research Institute (RTRI), part of JNR. They were responsible for much of the technical development of the first line, the Tōkaidō Shinkansen. All three had worked on aircraft design during World War II.{{Cite book | last = Hood | first = Christopher P. | title = Shinkansen – From Bullet Train to Symbol of Modern Japan | series = Routledge Contemporary Japan Series | publisher = Routledge | location=London | url =https://books.google.com/books?id=cwbklrvmS-oC | year = 2007 | isbn = 978-0-415-32052-8 | pages = 18–43}}

The popular English name bullet train is a literal translation of the Japanese term {{Nihongo|dangan ressha|弾丸列車}}, a nickname given to the project while it was initially discussed in the 1930s. The name stuck because of the original 0 Series Shinkansen's resemblance to a Minié ball and its high speed.

The Shinkansen name was first formally used in 1940 for a proposed standard-gauge passenger and freight line between Tokyo and Shimonoseki that would have used steam and electric locomotives with a top speed of {{convert|200|km/h|mph|abbr=on}}. Over the next three years, the Ministry of Railways drew up more ambitious plans to extend the line to Beijing (through a tunnel to Korea) and even Singapore, and build connections to the Trans-Siberian Railway and other trunk lines in Asia. These plans were abandoned in 1943 as Japan's position in World War II worsened. However, some construction did commence on the line; several tunnels on the present-day Shinkansen date to the war-era project.{{cite book |last1=Hood |first1=Christopher P. |title=Shinkansen: From Bullet Train to Symbol of Modern Japan |date=2006 |publisher=Routledge |isbn=978-0-415-32052-8 |pages=21–23}}

Following the end of World War II, high-speed rail was forgotten for several years while traffic of passengers and freight steadily increased on the conventional Tōkaidō Main Line along with the reconstruction of Japanese industry and economy. By the mid-1950s the Tōkaidō Line was operating at full capacity, and the Ministry of Railways decided to revisit the Shinkansen project. In 1957, Odakyu Electric Railway introduced its 3000 series SE Romancecar train, setting a world speed record of {{convert|145|km/h|mph|0|abbr=on}} for a narrow-gauge train when JNR leased a trainset in order to perform high-speed tests.{{cite book |last1=Nishiyama |first1=Takashi |title=Engineering War and Peace in Modern Japan, 1868–1964 |year=2014 |publisher=JHU Press |isbn=978-1-4214-1266-5 |page=124 |url=https://books.google.com/books?id=oG3eAgAAQBAJ |access-date=24 May 2024 |language=en}} This train gave designers the confidence that they could safely build an even faster standard-gauge train. Thus the first Shinkansen, the 0 series, was built on the success of the Romancecar.{{Citation needed|date=October 2021}}

In the 1950s, the Japanese national attitude was that as was happening in the United States, railways would soon be outdated and replaced by air travel and highways.{{cite web |title=The Shinkansen Turns 50: The History and Future of Japan's High-Speed Train |url=https://www.nippon.com/en/features/h00078/ |website=nippon.com |access-date=24 May 2024 |language=en |date=1 October 2014}} However, Shinji Sogō, President of Japanese National Railways, insisted strongly on the possibility of high-speed rail, and the Shinkansen project was implemented.{{Cite journal | last = Wakuda | first = Yasuo| title = Japanese Railway History 10- Railway Modernization and Shinkansen | journal = Japan Railway & Transport Review | volume = 11 | pages = 60–63 | publisher = Japan Railways (JR) | url = http://www.jrtr.net/jrtr11/history.html | access-date = 21 September 2010 | archive-date=13 June 2011 |archive-url= https://web.archive.org/web/20110613154641/http://www.jrtr.net/jrtr11/history.html }}

Government approval came in December 1958, and construction of the first segment of the Tōkaidō Shinkansen between Tokyo and Osaka started in April 1959. The cost of constructing the Shinkansen was at first estimated at nearly 200 billion yen,{{efn|194,800 million yen}}({{inflation|JP|194800000000|start_year=1959|fmt=eq||cursign=¥}}) which was raised in the form of a government loan, railway bonds and a low-interest loan of US$80 million ({{inflation|US|80000000|start_year=1959|fmt=eq||cursign=$}}) from the World Bank. Initial estimates, however, were understated and the actual cost was about 380 billion yen.{{cite book |editor1-last=Straszak |editor1-first=A. |editor2-last=Tuch |editor2-first=R. |title=The Shinkansen High-Speed Rail Network of Japan |date=1977 |publisher=Proceedings of an IIASA Conference, June 27–30, 1977 |pages=15, 18–19 |url=https://pure.iiasa.ac.at/id/eprint/1225/1/XB-80-508.pdf}} As the budget shortfall became clear in 1963, Sogo resigned to take responsibility.{{Cite journal |last=Smith |first = Roderick A. |title = The Japanese Shinkansen |journal = The Journal of Transport History |volume =24/2 |issue =2 |pages = 222–236 |publisher = Imperial College, London |year = 2003 |doi =10.7227/TJTH.24.2.6 |s2cid = 109409322 }}

The Tōkaidō Shinkansen began service on 1 October 1964, in time for the first Tokyo Olympics.Fukada, Takahiro, "[http://search.japantimes.co.jp/cgi-bin/nn20081209i1.html Shinkansen about more than speed]", The Japan Times, 9 December 2008, p. 3. The conventional Limited Express service took six hours and 40 minutes from Tokyo to Osaka, but the Shinkansen made the trip in just four hours, shortened to three hours and ten minutes by 1965. It enabled day trips between Tokyo and Osaka, the two largest metropolises in Japan, significantly changed the style of business and life of the Japanese people, and increased new traffic demand. The service was an immediate success, reaching the 100 million passenger mark in less than three years on 13 July 1967, and one billion passengers in 1976. Sixteen-car trains were introduced for Expo '70 in Osaka. With an average of 23,000 passengers per hour in each direction in 1992, the Tōkaidō Shinkansen was the world's busiest high-speed rail line.{{Cite journal |last=Okada |first=Hiroshi |date=October 1994 |title=Features and Economic and Social Effects of The Shinkansen |url=https://www.ejrcf.or.jp/jrtr/jrtr03/pdf/f09_oka.pdf |journal=Japan Transport and Railway Review |volume=3 |pages=9–16 |archive-url=https://web.archive.org/web/20220420121953/https://www.ejrcf.or.jp/jrtr/jrtr03/pdf/f09_oka.pdf |archive-date=20 April 2022}} As of 2014, the train's 50th anniversary, daily passenger traffic rose to 391,000 which, spread over its 18-hour schedule, represented an average of just under 22,000 passengers per hour.{{cite news |date=20 September 2014 |title=Half century on the shinkansen |url=https://www.japantimes.co.jp/opinion/2014/09/20/editorials/half-century-shinkansen/#.WsU4yNPwbOQ |newspaper=The Japan Times}}

The first Shinkansen trains, the 0 series, ran at speeds of up to {{convert|210|km/h|mph|0|abbr=on}}, later increased to {{convert|220|km/h|mph|0|abbr=on}}. The last of these trains, with their classic bullet-nosed appearance, were retired on 30 November 2008. A driving car from one of the 0 series trains was donated by JR West to the National Railway Museum in York, United Kingdom in 2001.{{cite web |date=1 August 2001 |title=Shinkansen comes to York |url=http://www.railwaygazette.com/news/single-view/view/shinkansen-comes-to-york.html |url-access=subscription |url-status=live |archive-url=https://web.archive.org/web/20210514234858/https://www.railwaygazette.com/news/shinkansen-comes-to-york/29664.article |archive-date=14 May 2021 |access-date=14 September 2014 |work=Railway Gazette}}

The Tōkaidō Shinkansen's rapid success prompted an extension westward to Okayama, Hiroshima and Fukuoka (the San'yō Shinkansen), which was completed in 1975.{{Cite journal |last=Taniguchi |first=Mamoru |date=1993 |title=The Japanese Shinkansen |journal=Built environment |volume=19 |issue=3/4 |page=216 |jstor=23288577 }} Prime Minister Kakuei Tanaka was an ardent supporter of the Shinkansen, and his government proposed an extensive network paralleling most existing trunk lines. Two new lines, the Tōhoku Shinkansen and Jōetsu Shinkansen, were built following this plan. Many other planned lines were delayed or scrapped entirely as JNR slid into debt throughout the late 1970s, largely because of the high cost of building the Shinkansen network.{{cn|date=April 2025}} By the early 1980s, the company was practically insolvent,{{cn|date=April 2025}} leading to its privatization in 1987.

Development of the Shinkansen by the privatised regional JR companies has continued, with new train models developed, each generally with its own distinctive appearance (such as the 500 series introduced by JR West). Since 2014, Shinkansen trains run regularly at speeds up to {{convert|320|km/h|mph|round=5|abbr=on}} on the Tōhoku Shinkansen; only the Shanghai maglev train, China Railway High-speed networks, and the Indonesian Jakarta-Bandung High-speed railway have commercial services that operate faster.{{cite web |date=18 May 2016 |title=The 10 fastest trains in the world |url=https://www.cntraveler.com/stories/2016-05-18/the-10-fastest-trains-in-the-world |url-status=live |archive-url=https://web.archive.org/web/20220623192616/https://www.cntraveler.com/stories/2016-05-18/the-10-fastest-trains-in-the-world |archive-date=23 June 2022 |access-date=8 December 2019 |publisher=cntraveler.com}}{{Cite web |date=11 October 2023 |title=雅万高铁助力印尼民众加速奔向美好生活 |trans-title=Jakarta-Bandung high-speed railway helps Indonesian people accelerate towards a better life |url=https://www.gov.cn/yaowen/liebiao/202310/content_6908475.htm |access-date=27 January 2024 |website=gov.cn |language=zh}}{{Update inline|date=January 2024|reason=Extensions in Kyushu and Hokuriku Shinkansen also need to be mentioned.}}

Since 1970, development has also been underway for the Chūō Shinkansen, a planned maglev line from Tokyo to Osaka. On 21 April 2015, a seven-car L0 series maglev trainset, planned to be used on the line, set a world speed record of {{convert|603|km/h|mph|0|abbr=on}}. The line is expected to operate at {{convert|500|km/h|mph|abbr=on|round=5}}, with the estimated travel time between Tokyo and Osaka taking 67 minutes. Construction commenced in 2011 and was originally scheduled to open in 2027, though it has since been delayed to at least 2034.{{Cite web |title=Japan railway firm pushes back maglev plan, possibly to 2034 or later |url=https://english.kyodonews.net/news/2024/03/bd9e1d3aec6a-urgent-japan-rail-operator-gives-up-plan-to-launch-maglev-train-in-2027.html |access-date=2024-12-30 |website=Kyodo News+}}

To enable high-speed operation, Shinkansen uses a range of advanced technology compared with conventional rail, achieving not only high speed but also a high standard of safety and comfort. Its success has influenced other railways in the world, demonstrating the importance and advantages of high-speed rail.

The majority of Shinkansen routes never intersect with slower, narrow-gauge conventional lines. Consequently, the Shinkansen is not affected by slower trains and has the capacity to operate many high-speed trains punctually. Routes are also completely grade separated from road traffic and tracks are strictly off-limits, with penalties against trespassing regulated by law. The routes make extensive use of tunnels and viaducts to go through and over obstacles rather than around them, with a minimum curve radius of {{convert|4000|m|ft|0|abbr=on}}, although the older Tōkaidō Shinkansen line has a minimum of {{convert|2500|m|ft|0|abbr=on}}.{{cite web|url=http://www.jrtr.net/jrtr11/history.html|title=Railway Modernization and Shinkansen|publisher=Japan Railway & Transport Review|date=30 April 2011|access-date=30 April 2011|archive-url=https://web.archive.org/web/20110613154641/http://www.jrtr.net/jrtr11/history.html|archive-date=13 June 2011}}

While most Shinkansen routes follow this pattern, two exceptions exist. They are the mini-shinkansen lines, which run on conventional lines converted to standard gauge; and the Hokkaido Shinkansen, which shares trackage with narrow-gauge freight trains through the Seikan Tunnel.

File:Toyohashi Station 001.JPG

The Shinkansen uses {{RailGauge|1435mm}} standard gauge in contrast to the {{RailGauge|1067mm|lk=on}} narrow gauge of most other lines in Japan. Continuous welded rail and swingnose crossing points are employed, eliminating gaps at turnouts and crossings. Long rails are used, joined by expansion joints to minimize gauge fluctuation due to thermal elongation and shrinkage.

A combination of ballasted and slab track is used, with slab track exclusively employed on concrete bed sections such as viaducts and tunnels. Slab track is significantly more cost-effective in tunnel sections, since the lower track height reduces the cross-sectional area of the tunnel, reducing construction costs up to 30%.Miura, S., Takai, H., Uchida, M., and Fukada, Y. "The Mechanism of Railway Tracks". Japan Railway & Transport Review, 15, 38–45, 1998

However, the smaller diameter of Shinkansen tunnels, compared to some other high-speed lines, has resulted in the issue of tunnel boom becoming a concern for residents living close to tunnel portals.

The slab track consists of rails, fasteners and track slabs with a cement asphalt mortar. On the roadbed and in tunnels, circular upstands, measuring {{convert|400|–|520|mm|abbr=in}} in diameter and {{convert|200|mm|in||abbr=in}} high, are located at 5-metre intervals. The prefabricated upstands are made of either reinforced concrete or pre-stressed reinforced concrete; they prevent the track slab from moving latitudinally or longitudinally. One track slab weighs approximately 5 tons and is {{convert|2220|–|2340|mm|abbr=in}} wide, {{convert|4900|–|4950|mm|abbr=in}} long and {{convert|160|–|200|mm|abbr=in}} thick.{{cite journal |last1=Ando |first1=Katsutoshi |display-authors=etal |date=2001 |title=Development of Slab Tracks for Hokuriku Shinkansen Line |journal=Quarterly Report of RTRI |volume=42 |issue=1 |pages=35–41 |doi=10.2219/rtriqr.42.35 |doi-access=free }}

The Shinkansen employs an ATC (automatic train control) system, eliminating the need for trackside signals. It uses a comprehensive system of automatic train protection. Centralized traffic control manages all train operations, and all tasks relating to train movement, track, station and schedule are networked and computerized.

Shinkansen uses a 25 kV AC overhead power supply (20 kV AC on Mini-shinkansen lines), to overcome the limitations of the 1,500 V direct current used on the existing electrified narrow-gauge system. Power is distributed along the train's axles to reduce the heavy axle loads under single power cars. The AC frequency of the power supply for the Tokaido Shinkansen is 60 Hz.

Shinkansen trains are electric multiple units (EMUs), offering fast acceleration, deceleration and reduced damage to the track because of the use of lighter vehicles compared to locomotives or power cars. The coaches are air-sealed to ensure stable air pressure when entering tunnels at high speed.

Shinkansen trains (excluding mini-Shinkansen) are also built to a larger loading gauge compared to conventional-speed rolling stock.{{cite web |url=http://www.mlit.go.jp/pubcom/06/pubcomt129/03.pdf |script-title=ja:鉄道に関する技術上の基準を定める省令等の解釈基準 |publisher=Ministry of Land, Infrastructure, Transport and Tourism |language=ja}} This larger loading gauge permits wider coaches, allowing for 5-abreast seating (2+3) in Standard Class coaches, compared to the more common 4-abreast (2+2) seating usually found elsewhere. On occasions, this wider loading gauge was also used to allow 6-abreast seating (3+3) on certain trains, such as the E1 and E4 series sets. This, combined with a lack of power cars, allows for a higher passenger capacity within a shorter train length. However, since mini-Shinkansen lines are effectively track-regauged conventional lines, the conventional loading gauge for 1,067mm lines still applies on mini-Shinkansen lines.

The Shinkansen has used EMUs from the outset, with the 0 Series Shinkansen having all axles powered. Other railway manufacturers were traditionally reluctant or unable to use distributed traction configurations (Talgo, the German ICE 2 and the French (and subsequently South Korean) TGV (and KTX-I and KTX-Sancheon) use the locomotive (also known as power car) configuration with the Renfe Class 102 and continues with it for the Talgo AVRIL because it is not possible to use powered bogies as part of Talgo's bogie design, which uses a modified Jacobs bogie with a single axle instead of two and allows the wheels to rotate independently of each other, on the ICE 2, TGV and KTX it is because it easily allows for a high ride quality and less electrical equipment.{{cite web|url=http://www.ejrcf.or.jp/jrtr/jrtr17/pdf/f40_technology.pdf |archive-url=https://ghostarchive.org/archive/20221010/http://www.ejrcf.or.jp/jrtr/jrtr17/pdf/f40_technology.pdf |archive-date=2022-10-10 |url-status=live|title=What Drives Electrical Multiple Units?|author=Hiroshi Hata|website=Ejrcf.or.jp|access-date=5 March 2022}}) In Japan, significant engineering desirability exists for the electric multiple unit configuration. A greater proportion of motored axles permits higher acceleration, so the Shinkansen does not lose as much time if stopping frequently. Shinkansen lines have more stops in proportion to their lengths than high-speed lines elsewhere in the world.

The main Shinkansen lines are:

In practice, the Tokaido, San'yō, and Kyushu lines form a contiguous west/southbound line from Tokyo, as train services run between the Tokaido and San'yō lines and between the San'yō and Kyushu lines, though the lines are operated by different companies.

The Tokaido Shinkansen tracks are not physically connected to the lines of the Tohoku Shinkansen at Tokyo Station, as they use different electrification standards, signaling systems, and earthquake mitigation devices. There also exists a dispute between JR East and JR Central about the use of the two platforms which were added to the Tokaido line's half of Tokyo station. Before JNR's privatization, they were conceived as being shared with the Tohoku line, and their construction used funds allocated to the Tohoku line's extension to Tokyo; however, the extension was finished after privatization, by which time the platforms were owned by JR Central. Therefore, there is no through service between those lines. All northbound services from Tokyo travel along the Tohoku Shinkansen until at least Ōmiya before splitting off towards Sendai or Takasaki.

Two further lines, known as Mini-shinkansen, have also been constructed by re-gauging and upgrading existing sections of line:

There are two standard-gauge lines not technically classified as Shinkansen lines but run Shinkansen trains as they use tracks leading to Shinkansen storage/maintenance yards:

• Hakata Minami Line (Hakata – Hakataminami)
• Gala-Yuzawa Line – technically a branch of the Jōetsu Line – (Echigo-Yuzawa – Gala-Yuzawa)

The following lines are under construction. These lines except Chūō Shinkansen, called {{ill|Seibi Shinkansen|ja|整備新幹線}} or planned Shinkansen, are the Shinkansen projects designated in the {{ill|Basic Plan of the Shinkansen Railway|ja|建設を開始すべき新幹線鉄道の路線を定める基本計画}} decided by the government.

• Hokkaido Shinkansen from {{STN|Shin-Hakodate-Hokuto|x}} to {{STN|Sapporo|x}} is under construction and scheduled to open by 2038.
• Chūō Shinkansen (Tokyo–Nagoya–Osaka) is the first maglev Shinkansen line, which has been under construction since 2014. JR Central originally aimed to begin commercial service between Tokyo and Nagoya in 2027. However, in 2024, Central Japan Railway Co President Shunsuke Niwa said that due to construction delays a 2027 opening was now impossible and it is not expected to open until at least 2034.{{Cite web|title=Japan rail operator gives up plan to launch maglev train in 2027|url=https://japantoday.com/category/business/update1-japan-rail-operator-gives-up-plan-to-launch-maglev-train-in-2027|access-date=30 March 2024|website=Japan Today|date=30 March 2024|language=en-GB|archive-date=30 March 2024|archive-url=https://web.archive.org/web/20240330000706/https://japantoday.com/category/business/update1-japan-rail-operator-gives-up-plan-to-launch-maglev-train-in-2027|url-status=live}}

• The extension of Hokuriku Shinkansen to Osaka is proposed, with the route via Obama and Kyoto selected by the government on 20 December 2016. Construction is proposed to commence in 2030, and take 15 years.
• Nishi Kyushu Shinkansen has been built to full Shinkansen standards between Takeo-Onsen and Nagasaki, with the existing narrow-gauge line from Shin-Tosu to Takeo Onsen to remain as narrow-gauge track, although there is a proposal to build the section between Shin-Tosu and Takeo Onsen to full Shinkansen standards. In 2018, the Ministry of Land, Infrastructure, Transport and Tourism released cost-benefit analysis results to compare and contrast full Shinkansen, Mini-shinkansen, and Gauge Change Train for this section.{{cite web |date=30 March 2018 |title=九州新幹線（西九州ルート）の整備のあり方に係る調査について |trans-title=About the investigation about the maintenance of the Kyushu Shinkansen (West Kyushu route) |url=https://www.mlit.go.jp/report/press/tetsudo03_hh_000081.html |url-status=live |archive-url=https://web.archive.org/web/20220705064325/https://www.mlit.go.jp/report/press/tetsudo03_hh_000081.html |archive-date=5 July 2022 |access-date=29 August 2021 |website=mlit.co.jp |language=ja}}

The Narita Shinkansen project to connect Tokyo to Narita International Airport, initiated in the 1970s but halted in 1983 after landowner protests, has been officially cancelled and removed from the Basic Plan governing Shinkansen construction. Parts of its planned right-of-way were used by the Narita Sky Access Line which opened in 2010, and the Keiyo Line reused space originally set aside for the Narita Shinkansen terminus at Tokyo Station. Although the Sky Access Line uses standard-gauge track, it was not built to Shinkansen specifications and there are no plans to convert it into a full Shinkansen line.

In 2016, the Shikoku and Trans-Shikoku Shinkansen were identified as potential future projects in a review of long-term plans for the Shikoku area and funds allocated towards the planning of the route.{{cite news |title=新幹線誘致、オ– ル四国で 4県や四経連で新組織結成 |url=https://www.nikkei.com/article/DGXLZO18571700W7A700C1LA0000/ |access-date=21 February 2019 |publisher=日本経済新聞}} A profitability study has also been commissioned by the city of Oita in 2018 that found the route to be potentially profitable{{cite news |title=豊予海峡ル –ト・新幹線案 １日６８００人利用で黒字 大分市試算 [大分県] |language=ja |trans-title=Toyoyo Strait Route / Shinkansen Proposal Profitable for 6800 people a day Oita City Estimate [Oita Prefecture] |publisher=西日本新聞 |url=https://www.nishinippon.co.jp/nnp/oita/article/385544/ |access-date=21 February 2019 |archive-url=https://web.archive.org/web/20210512114900/https://www.nishinippon.co.jp/item/n/385544/ |archive-date=12 May 2021}}

In addition, the Basic Plan specified that the Jōetsu Shinkansen should start from Shinjuku, not Tokyo Station, which would have required building an additional {{convert|30|km|mi|abbr=on}} of track between Shinjuku and Ōmiya. While no construction work was ever started, land along the proposed track, including an underground section leading to Shinjuku Station, remains reserved. If capacity on the Tokyo–Ōmiya section proves insufficient at some point, construction of the Shinjuku–Ōmiya link may be reconsidered.

In December 2009, then transport minister Seiji Maehara proposed a bullet train link to Haneda Airport, using an existing spur that connects the Tōkaidō Shinkansen to a train depot. JR Central called the plan "unrealistic" due to tight train schedules on the existing line, but reports said that Maehara wished to continue discussions on the idea.{{Cite news|title= Maehara sounds out JR Tokai over shinkansen link for Haneda airport|newspaper= Japan Today|date= 28 December 2009|url= http://www.japantoday.com/category/national/view/maehara-sounds-out-jr-tokai-over-shinkansen-link-for-haneda-airport|access-date= 28 December 2009}}{{dead link|date=May 2018 |bot=InternetArchiveBot |fix-attempted=yes }} The succeeding minister has not indicated whether this proposal remains supported. While the plan may become more feasible after the opening the Chūō Shinkansen (sometimes referred to as a bypass to the Tokaido Shinkansen) frees up capacity, construction is already underway for other rail improvements between Haneda and Tokyo station expected to be completed prior to the opening of the 2020 Tokyo Olympics, so any potential Shinkansen service would likely offer only marginal benefit. Despite these plans ultimately not being realized (owing in part due to the effects of the COVID-19 pandemic), rail projects in the vicinity of Haneda Airport, including the Haneda Airport Access Line and the Tokyo Rinkai Subway Line, continue to undergo planning.{{cite web |date=21 January 2021 |title=JR East's Haneda Airport Access Line to Open in FY 2029 |url=https://www.nippon.com/en/news/yjj2021012001065/ |access-date=4 January 2023 |archive-date=25 January 2021 |archive-url=https://web.archive.org/web/20210125172245/https://www.nippon.com/en/news/yjj2021012001065/ }}

For trips exclusively on one Shinkansen, the base fare and Shinkansen express fare may be combined into a single ticket.]]Originally intended to carry passenger trains by day and freight trains by night, the Shinkansen lines carried exclusively passengers for the first five and a half decades of their operation. Light freight has been carried on some passenger services since 2019, and there are plans to expand this with freight-only trains in the future.{{cite news |title=Japanese high speed rail freight services expand |url=https://www.railwaygazette.com/high-speed/japanese-high-speed-rail-freight-services-expand/66634.article |access-date=5 June 2024 |work=Railway Gazette International |publisher=DVV Media International |date=5 June 2024}}{{cite news |title=荷物専用の臨時列車、上越新幹線を走る JR東が初めて実験：朝日新聞デジタル |url=https://www.asahi.com/articles/ASR805WFFR80ULFA022.html |access-date=5 June 2024 |work=朝日新聞デジタル |date=31 August 2023 |language=ja}}

The system shuts down between midnight and 06:00 every day for maintenance. Japan's few remaining overnight passenger trains run on the older, narrow-gauge network that the Shinkansen parallels.

There are three principal service types on the Shinkansen:

• Express services – these stop at only the very largest stations and, as a result, are the fastest Shinkansen services measured by average speed.
• Semi-express services – these stop at certain smaller stops alongside stopping at all the largest stations. These allow for faster connections from smaller stops to larger stations than would be otherwise possible with a local service.
• Local services – these stop at every station along the Shinkansen line. Consequently, local services are the slowest Shinkansen services measured by average speed. Frequently, these services only operate on a part of the line, instead of covering the entirety.

Trains are up to sixteen cars long. With each car measuring {{convert|25|m|ft|abbr=on}} in length, the longest trains are 400 m ({{fraction|4}} mile) end to end. Stations are similarly long to accommodate these trains.

The Shinkansen is very reliable thanks to several factors, including its near-total separation from slower traffic. There are separate laws governing interfering with or otherwise obstructing Shinkansen trains, tracks, or its operation.{{fact|date=November 2024}} In 2016, JR Central reported that the Shinkansen's average delay from schedule per train was 24 seconds.

In the event of an earthquake, an earthquake detection system can bring the train to a stop very quickly; newer trainsets are lighter and have stronger braking systems, allowing for quicker stopping.

On 23 January 2024, a massive power outage struck the Tohoku, Hokuriku and Joetsu Shinkansen lines, resulting in the cancellation of 283 trains and affecting about 120,000 passengers. JR East said that the outage was caused by a Kagayaki service train touching an overhead power cable which was left dangling after the metal rod supporting it fractured between Omiya Station in Saitama and Ueno Station in Tokyo. The incident damaged the train's pantographs and a window,{{cite web |date=24 January 2024 |title=JR East: Damage to overhead power cable part led to Shinkansen disruption |url=https://www3.nhk.or.jp/nhkworld/en/news/20240124_22/ |access-date=24 January 2024 |work=NHK}} while two railway employees were hospitalized following an explosion that occurred at the site during repairs.{{cite web |date=24 January 2024 |title=Disruption of Japan's Shinkansen service sends passengers scrambling |url=https://www3.nhk.or.jp/nhkworld/en/news/backstories/3009/ |access-date=24 January 2024 |work=NHK}} Most Shinkansen services were restored the following morning.{{cite web |date=24 January 2024 |title=Bullet trains restart in east Japan 20 hours after power outage |url=https://english.kyodonews.net/news/2024/01/7398611df12a-bullet-train-services-restart-in-east-japan-after-power-outage.html |access-date=24 January 2024 |work=Kyodo News}}

The Shinkansen has had a significant beneficial effect on Japan's business, economy, society, environment and culture beyond mere construction and operational contributions.{{cite web |title=Features and Economic and Social Effects of The Shinkansen |url=http://www.jrtr.net/jrtr03/f09_oka.html |archive-url=https://web.archive.org/web/20110110165031/http://www.jrtr.net/jrtr03/f09_oka.html |archive-date=10 January 2011 |access-date=30 November 2009 |publisher=Jrtr.net}} The resultant time savings alone from switching from a conventional to a high-speed network have been estimated at 400 million hours, and the system has an economic contribution of {{JPY|500 billion}} per year. That does not include the savings from reduced reliance on imported fuel, which also has national security benefits. Shinkansen lines, particularly in the very crowded coastal Taiheiyō Belt megalopolis, met two primary goals:

• Shinkansen trains reduced the congestion burden on regional transportation by increasing throughput on a minimal land footprint, therefore being economically preferable compared to modes (such as airports or highways) common in less densely populated regions of the world.
• As rail was already the primary urban mode of passenger travel, from that perspective it was akin to a sunk cost; there was not a significant number of motorists to convince to switch modes. The initial megalopolitan Shinkansen lines were profitable and paid for themselves. Connectivity rejuvenated rural towns such as Kakegawa that would otherwise be too distant from major cities.

However, upon the introduction of the 1973 Basic Plan the initial prudence in developing Shinkansen lines gave way to political considerations to extend the mode to far less populated regions of the country, partly to spread these benefits beyond the key centres of Kanto and Kinki. Although in some cases regional extension was frustrated by protracted land acquisition (sometimes influenced by the cancellation of the Narita Shinkansen following fierce protests by locals), over time Shinkansen lines were built to relatively sparsely populated areas with the intent to disperse the population away from the capital.

Such expansion had a significant cost. JNR, the national railway company, was already burdened with subsidizing unprofitable rural and regional railways. It then assumed Shinkansen construction debt until the government corporation eventually owed some {{JPY|28 trillion}}, contributing to it being regionalised and privatized in 1987.{{cite web |url=http://www.jrtr.net/jrtr22/F23_Kakumoto.html |title=Sensible Politics and Transport Theories? |publisher=Jrtr.net |access-date=30 November 2009 |archive-url=https://web.archive.org/web/20090606151933/http://www.jrtr.net/jrtr22/F23_Kakumoto.html |archive-date=6 June 2009 }} The privatized JRs eventually paid {{JPY|9.2 trillion}} to acquire JNR's Shinkansen network.

Following privatization, the JR group of companies have continued Shinkansen network expansion to less populated areas, but with far more flexibility to spin-off unprofitable railways or cut costs than in JNR days. An important factor is the post bubble zero interest-rate policy that allows JR to borrow huge sums of capital without significant concern regarding repayment timing.

A UCLA study found that the presence of a Shinkansen line had improved housing affordability by making it more realistic for lower-income city workers to live in exurban areas much further away from the city, which tend to have cheaper housing options. That in turn helps the city to "decentralise" and reduce city property prices.{{cite web |last=Eaton |first=Joe |title=High-Speed Rail Helped Keep Housing Affordable in Japan.

Traveling by the Tokaido Shinkansen from Tokyo to Osaka produces only around 16% of the carbon dioxide of the equivalent journey by car, a saving of 15,000 tons of {{co2}} per year.

Noise pollution concerns have made increasing speed more difficult. In Japan, population density is high and there have been strong protests against the Shinkansen's noise pollution. Its noise is thus limited to less than 70 dB in residential areas.{{cite web |title=新幹線鉄道騒音に係る環境基準について |trans-title=About environmental standards related to Shinkansen railway noise |url=http://www.env.go.jp/kijun/oto3.html |url-status=live |archive-url=https://web.archive.org/web/20220510054046/http://www.env.go.jp/kijun/oto3.html |archive-date=10 May 2022 |access-date=10 July 2022 |website=env.go.jp |publisher= |language=ja}}

Improvement and reduction of the pantograph, weight saving of cars, and construction of noise barriers and other measures have been implemented. Research is primarily aimed at reducing operational noise, particularly the tunnel boom phenomenon caused when trains transit tunnels at high speed.

Because of the risk of earthquakes in Japan, the Urgent Earthquake Detection and Alarm System (UrEDAS) (an earthquake warning system) was introduced in 1992. It enables automatic braking of Shinkansen trains in the event of large earthquakes.

The Tōkaidō Shinkansen often experiences heavy snow in the area around Maibara Station between December and February, requiring trains to reduce speed thus disrupting the timetable. Snow-dispersing sprinkler systems have been installed, but delays of 10–20 minutes still occur during snowy weather. Snow-related treefalls have also caused service interruptions. Along the Jōetsu Shinkansen route, snow can be very heavy, with depths of two to three metres; the line is equipped with stronger sprinklers and slab track to mitigate the snow's effects. Despite having multiple days with delays longer than 30 minutes, the Tōhoku Shinkansen still presents a slight advantage in reliability compared to air travel on days with significant snowfall.

E5 series trains, capable of up to {{convert|320|km/h|mph|abbr=on|round=5}}, initially limited to {{convert|300|km/h|mph|0|abbr=on}}, were introduced on the Tōhoku Shinkansen in March 2011. Operation at the maximum speed of {{convert|320|km/h|mph|abbr=on|round=5}} between {{STN|Utsunomiya|x}} and {{STN|Morioka|x}} on this route commenced on 16 March 2013. It reduced the journey time to around 3 hours for trains from Tokyo to Shin-Aomori, a distance of {{convert|674|km|mi|abbr=on}}.

Extensive trials using the Fastech 360 test trains have shown that operation at {{convert|360|km/h|mph|0|abbr=on}} is not feasible because of problems of noise pollution (particularly tunnel boom), overhead wire wear, and braking distances. On 30 October 2012, JR East announced that it was pursuing research and development to increase speeds to {{convert|360|km/h|mph|0|abbr=on}} on the Tohoku Shinkansen by 2020.{{cite web|url=http://www.jreast.co.jp/press/2012/20121013.pdf |script-title=ja:グループ経営構想V |trans-title=Group Business Vision V |date=30 October 2012 |publisher=East Japan Railway Company |location=Japan |page=5 |language=ja |archive-url=https://web.archive.org/web/20121202011722/http://www.jreast.co.jp/press/2012/20121013.pdf |archive-date= 2 December 2012 |access-date=17 November 2012 }} The ALFA-X is undergoing testing.

Upon commencement of services in 2016, the maximum speed on the approximately {{convert|82|km|mi|abbr=on}} dual gauge section of the Hokkaido Shinkansen (including through the Seikan Tunnel) was {{convert|140|km/h|mph|round=5|abbr=on}}, which was increased to {{convert|160|km/h|mph|round=5|abbr=on}} by March 2019.{{Cite web |date=31 March 2021 |title=Seikan tunnel Shinkansen speed-up saves 3 min |url=https://www.railwaygazette.com/high-speed/seikan-tunnel-shinkansen-speed-up-saves-3-min/58804.article |url-access=subscription |url-status=live |archive-url=https://web.archive.org/web/20210919081124/https://www.railwaygazette.com/high-speed/seikan-tunnel-shinkansen-speed-up-saves-3-min/58804.article |archive-date=19 September 2021 |access-date=5 March 2022 |website=Railway Gazette International}} There are approximately 50 freight trains using the dual gauge section each day, so limiting the travel of such trains to times outside of Shinkansen services is not an option. Because of this and other weather-related factors cited by JR East and JR Hokkaido, the fastest journey time between Tokyo and Shin-Hakodate-Hokuto is 3 hours, 57 minutes.

During the 2020-21 New Year Holiday period, certain Shinkansen services were operated at {{convert|210|km/h|mph|round=5|abbr=on}} on the dual gauge section and was proposed again for the Golden Week Holiday period from 3–6 May 2021, due to fewer freight trains operating.

To achieve the full benefit of Shinkansen trains travelling on the dual gauge section at {{convert|260|km/h|mph|round=5|abbr=on}} (the maximum speed proposed through the tunnel), alternatives are being considered, such as a system to automatically slow Shinkansen trains to {{convert|200|km/h|mph|round=5|abbr=on}} when passing narrow-gauge trains, and/or loading freight trains onto special "Train on Train" standard-gauge trains (akin to a covered piggyback flatcar train) built to withstand the shock wave of oncoming Shinkansen trains traveling at full speed. This would enable a travel time from Tokyo to Shin-Hakodate-Hokuto of 3 hours and 45 minutes, a saving of 12 minutes.

To extend the benefits of the Hokuriku Shinkansen to stations west of Tsuruga before the line to Osaka is completed, JR West was working in partnership with Talgo on the development of a Gauge Change Train (CGT) capable of operating under both the 25 kV AC electrification used on the Shinkansen and the 1.5 kV DC system employed on conventional lines.

{{Main|Nishi Kyushu Shinkansen}}

JR Kyushu opened the Nishi Kyushu Shinkansen from {{STN|Takeo-Onsen|x}} to {{STN|Nagasaki|x}} (built to full Shinkansen standard) on 23 September 2022, with the existing narrow-gauge section between Shin-Tosu and Takeo Onsen proposed to be upgraded as part of this project.

This proposal initially involved introducing Gauge Change Trains (GCT) travelling from Hakata to Shin-Tosu ({{convert|26.3|km|mi|abbr=on}}) on the existing Kyushu Shinkansen line, then passing through a specific gauge changing (standard to narrow) section of track linking to the existing Nagasaki Main Line, along which it would travel to Hizen Yamaguchi ({{convert|37.6|km|mi|abbr=on}}), then onto the Sasebo Line to Takeo-Onsen ({{convert|13.7|km|mi|abbr=on}}), where another gauge changing section (narrow to standard) would lead onto the final Shinkansen line to Nagasaki ({{convert|66|km|mi|abbr=on}}). However, significant technical issues with the axles of the GCT resulted in its cancellation.

On 28 October 2020, JR Kyushu announced it would utilize a 6-car version of the N700S for the isolated Shinkansen section from Nagasaki, with 'cross platform' change to a relay service at Takeo Onsen station to connect to Hakata.{{Cite web |title=Shorter N700S to serve Nagasaki |url=https://www.railwaygazette.com/high-speed/shorter-n700s-to-serve-nagasaki/57681.article |url-access=subscription |url-status=live |archive-url=https://web.archive.org/web/20210628222520/https://www.railwaygazette.com/high-speed/shorter-n700s-to-serve-nagasaki/57681.article |archive-date=28 June 2021 |access-date=5 March 2022 |website=Railway Gazette International}} JR Kyushu also announced the service would continue to use the name 'Kamome' for the Hakata-Nagasaki service, which has been in use since 1961.{{cite web |title=2022年度秋頃に西九州新幹線が開業します!列車名「かもめ」 |trans-title=The West Kyushu Shinkansen will open in the fall of 2022!

The Shinkansen line shortens the distance between Hakata and Nagasaki by 6.2% ({{convert|9.6|km|mi|abbr=on}}), and while only 64% of the route is built to full Shinkansen standards, it eliminated the slowest sections of the previous narrow-gauge route.

As part of the GCT proposal, the {{convert|12.8|km|mi|abbr=on}} section of single track between Hizen Yamaguchi and Takeo Onsen was proposed to be duplicated. However, due to the issues with the development of the GCT, the proposal did not advance.

JR Central originally aimed to begin commercial service between Tokyo and Nagoya in 2027. However, in 2024, Central Japan Railway Co President Shunsuke Niwa said that due to construction delays a 2027 opening was now impossible and it is not expected to open until at least 2034.

Following the shortest route (through the Japanese Alps), JR Central estimates that it will take 40 minutes to run from Shinagawa to Nagoya. The planned travel time from Shinagawa to Shin-Osaka is 1 hour 7 minutes. The Tokaido Shinkansen {{asof|2010|lc=y}} had a minimum connection time of 2 hours 19 minutes.{{cite news |date=28 October 2010 |title=Maglev car design unveiled |work=The Japan Times |url=https://www.japantimes.co.jp/news/2010/10/28/business/maglev-car-design-unveiled/ |access-date=11 July 2022 |archive-url=https://web.archive.org/web/20190108044409/https://www.japantimes.co.jp/news/2010/10/28/business/maglev-car-design-unveiled/ |archive-date=8 January 2019}}

The route for the Nagoya to Osaka section is also contested. It is planned to go via Nara, about {{convert|40|km|mi||abbr=on}} south of Kyoto. Kyoto is lobbying to have the route moved north and be largely aligned with the existing Tokaido Shinkansen, which services Kyoto and not Nara.{{cite news |date=3 May 2012 |title=Economy, prestige at stake in Kyoto-Nara maglev battle |work=The Japan Times |url=https://www.japantimes.co.jp/news/2012/05/03/national/economy-prestige-at-stake-in-kyoto-nara-maglev-battle/ |access-date=3 May 2012 |archive-url=https://web.archive.org/web/20190108060652/https://www.japantimes.co.jp/news/2012/05/03/national/economy-prestige-at-stake-in-kyoto-nara-maglev-battle/ |archive-date=8 January 2019}}

{{Nihongo|Mini-shinkansen|ミニ新幹線}} is the name given to the routes where former narrow-gauge lines have been converted to standard gauge to allow Shinkansen trains to travel to cities without the expense of constructing full Shinkansen standard lines.

Two mini-shinkansen routes have been constructed: the Yamagata Shinkansen and Akita Shinkansen. Shinkansen services to these lines traverse the Tohoku Shinkansen line from Tokyo before branching off to traditional main lines. On both the Yamagata/Shinjo and Akita lines, the narrow-gauge lines were regauged, resulting in the local services being operated by standard-gauge versions of {{Track gauge|1,067mm}} suburban/interurban rolling stock. On the Akita line between Omagari and Akita, one of the two narrow-gauge lines was regauged, and a section of the remaining narrow-gauge line is dual gauge, providing the opportunity for Shinkansen services to pass each other without stopping.

The maximum speed on these lines is {{convert|130|km/h|mph|abbr=on}}, however the overall travel time to/from Tokyo is improved due to the elimination of the need for passengers to change trains at Fukushima and Morioka respectively.

As the Loading gauge (size of the train that can travel on a line) was not altered when the rail gauge was widened, only Shinkansen trains specially built for these routes can travel on the lines. They are the E3 and E6 series trains.

As some of the E3 series on the Yamagata Shinkansen will be retiring soon, they will be replaced by the new E8 Series Shinkansen trains from Spring 2024 with an increased speed of {{convert|300|km/h|mph|0|abbr=on}}, up from the {{convert|275|km/h|mph||abbr=on}} on the E3 Series trains.{{Citation needed|date=March 2022}}

Whilst no further Mini-shinkansen routes have been proposed, it remains an option for providing Shinkansen services to cities on the narrow-gauge network.

Construction of a Base tunnel on the Yamagata Shinkansen is proposed, with JR East having undertaken a survey of a planned route from Niwasaka to Sekine, just south of Yonezawa station.{{Cite web |date=7 November 2022 |title=Yamagata mini-Shinkansen base tunnel proposal makes progress |url=https://www.railwaygazette.com/infrastructure/yamagata-mini-shinkansen-base-tunnel-proposal-makes-progress/62884.article |url-access=subscription |access-date=12 November 2022 |website=Railway Gazette International |language=en}} {{convert|23.1|km|mi|abbr=on}} of the proposed {{convert|24.9|km|mi|abbr=on}} line would be in tunnel, mostly to the north of the existing {{convert|88|km|mi|abbr=on}} Fukushima – Yamagata section. To be built on an improved alignment, the tunnel would lower journey times between Fukushima and Yamagata by ~10 min due to a proposed line speed of up to 200 km/h.

The tunnel would avoid the Itaya Toge pass through the Ou mountains west of Fukushima. Gradients range from 3.0% to 3.8% and the line reaches an altitude of {{convert|548|m|ft|abbr=on}}. The curvature and steep grades limit train speeds to {{convert|55|km/h|mph|abbr=on}} or less, and the line is vulnerable to heavy rain and snowfall as well as high winds. Between 2011 and 2017 a total of 410 Yamagata mini-Shinkansen services were either suspended or delayed, and 40% of these incidents occurred on the line over the Itaya Toge pass.

If the {{Yen|150 billion}} base tunnel is authorised, detailed design would take five years and construction another 15 years. The cost could increase by {{Yen|12 billion}} if the tunnel were to be built with a cross-section large enough to permit the line to be upgraded to the full Shinkansen loading gauge.

{{Main|Gauge Change Train}}

This is the name for the concept of using a single train that is designed to travel on both {{RailGauge|1067mm}} narrow-gauge railway lines and the {{RailGauge|1435mm}} standard gauge used by Shinkansen train services in Japan. The trucks/bogies of the Gauge Change Train (GCT) allow the wheels to be unlocked from the axles, narrowed or widened as necessary, and then relocked. This allows a GCT to traverse both standard-gauge and narrow-gauge tracks without the expense of regauging lines.

Three test trains were constructed, with the second set having completed reliability trials on the Yosan Line east of Matsuyama (in Shikoku) in September 2013. The third set was undertaking gauge changing trials at Shin-Yatsushiro Station (on Kyushu), commencing in 2014 for a proposed three-year period, however testing was suspended in December 2014 after accumulating approximating {{convert|33,000|km|mi|abbr=on}}, following the discovery of defective thrust bearing oil seals on the bogies.{{cite web |date=24 December 2014 |title= |script-title=ja:九州新幹線のフリーゲージトレイン、欠損が見つかり耐久走行試験を一時休止 |trans-title=Kyushu Shinkansen Free Gauge Train endurance testing suspended following discovery of defects |url=http://news.mynavi.jp/news/2014/12/24/335/ |archive-url=https://web.archive.org/web/20211227101301/https://news.mynavi.jp/article/20141224-a335/ |archive-date=27 December 2021 |access-date=11 July 2022 |work=Mynavi News |publisher=Mynavi Corporation |location=Japan |language=ja}} The train was being trialled between Kumamoto, travelling on the narrow-gauge line to Shin-Yatsushiro, where a gauge changer was installed, so the GCT could be trialled on the Shinkansen line to Kagoshima. It was anticipated the train would travel approximately {{convert|600,000|km|mi|abbr=on}} over the three-year trial.

A new "full standard" Shinkansen line was opened in 2022 from Takeo Onsen to {{STN|Nagasaki|x}}, with the Shin-Tosu – Takeo Onsen section of the Nishi Kyushu Shinkansen remaining narrow gauge. GCTs were proposed to provide Shinkansen service from the line's opening, however with the GCT being cancelled, JR Kyushu announced it would provide an interim 'relay' service.

There are currently no further proposals for use of the GCT, nor any development work on it.

Compared with air transport, the Shinkansen has several advantages, including scheduling frequency and flexibility, punctual operation, comfortable seats, lower carbon emissions, and convenient city-centre terminals.

Shinkansen fares are generally competitive with domestic air fares. From a speed and convenience perspective, the Shinkansen's market share has surpassed that of air travel for journeys of less than {{convert|750|km|mi|abbr=on}}, while air and rail remain highly competitive with each other in the {{convert|800|–|900|km|mi|abbr=on}} range and air has a higher market share for journeys of more than {{convert|1,000|km|mi|abbr=on}}.{{cite web|last1=Shiomi|first1=Eiji|title=Do Faster Trains Challenge Air Carriers?|url=http://www.jrtr.net/jrtr19/F04_Shiomi.html|website=Japan Railway & Transport Review|access-date=7 August 2015|archive-url=https://web.archive.org/web/20150930083648/http://www.jrtr.net/jrtr19/F04_Shiomi.html|archive-date=30 September 2015}}

During snowy weather, the Shinkansen is known to face fewer delays compared to air travel due to snow. One study done in 2016 concluded that the Tohoku Shinkansen between Tokyo and Aomori had substantially fewer days with delays longer than 30 minutes compared to air travel.{{Cite journal |last=Kojima |first=Yasuhiro |date=2017 |title=The impact of new Shinkansen lines (Tohoku Shinkansen (Hachinohe – Shin-Aomori) and Kyusyu Shinkansen (Hakata – Shin-Yatsushiro)) |journal=Transportation Research Procedia |volume=25 |pages=344–357 |doi=10.1016/j.trpro.2017.05.412|doi-access=free }}

Shinkansen runs between these cities in about two hours or less.
• Tokyo – Osaka ({{convert|515|km|mi|disp=semicolon|abbr=on}}): Shinkansen is dominant because of fast (2 hours 22 minutes) and frequent service (up to every 10 minutes by Nozomi); however, air travel has a certain share (~20–30%).
• Tokyo – Okayama ({{convert|676|km|mi|disp=semicolon|abbr=on}}), Tokyo – Hiroshima ({{convert|821|km|mi|disp=semicolon|abbr=on}}): Shinkansen is reported to have increased its market share from ~40% to ~60% over the last decade.{{cite web |url=http://asia.nikkei.com/Business/Trends/Japanese-airlines-facing-threat-from-below |title=Japanese airlines facing threat from below- Nikkei Asian Review |work=Nikkei Asian Review |publisher=Asia.nikkei.com |date=25 November 2013 |access-date=7 February 2014 |archive-url=https://web.archive.org/web/20140301141326/http://asia.nikkei.com/Business/Trends/Japanese-airlines-facing-threat-from-below |archive-date=1 March 2014 }} The Shinkansen takes about three to four hours and there are Nozomi trains every 30 minutes, but airlines may provide cheaper fares, attracting price-conscious passengers.
• Tokyo – Fukuoka ({{convert|1,069|km|mi|disp=semicolon|abbr=on}}): The Shinkansen takes about five hours on the fastest Nozomi, and discount carriers have made air travel far cheaper, so most people choose air. Additionally, unlike many cities, there is very little convenience advantage for the location of the Shinkansen stations of the two cities as Fukuoka Airport is located near the central Tenjin district, and Fukuoka City Subway Line 1 connects the Airport and Tenjin via Hakata Station and Haneda Airport is similarly conveniently located.
• Osaka – Fukuoka ({{convert|554|km|mi|disp=semicolon|abbr=on}}): One of the most competitive sections. The Shinkansen takes about two and a half hours by Nozomi or Mizuho, and the JR West Hikari Rail Star or JR West/JR Kyushu Sakura trains operate twice an hour, taking about 2 hours and 40 minutes between the two cities. Again the location of the airports involved (Itami Airport in Osaka's case) helps with the popularity of air travel.
• Tokyo – Aomori ({{convert|675|km|mi|disp=semicolon|abbr=on}}): The fastest Shinkansen service between these cities is 3 hours. JAL is reported to have reduced the size of planes servicing this route since the Shinkansen extension opened in 2010.
• Tokyo – Hokuriku ({{convert|345|km|mi|disp=semicolon|abbr=on}}): The fastest Shinkansen service between these areas is 2{{frac|1|2}} hours. ANA is reported to have reduced the number of services from Tokyo to Kanazawa and Toyama from 6 to 4 per day since the Shinkansen extension opened in 2015. The share of passengers travelling this route by air is reported to have dropped from 40% to 10% in the same period.

Railways using Shinkansen technology are not limited to those in Japan.

A 0 Series Shinkansen power car which was used in Taiwan for testing is on display at Tainan HSR station. This is one of only two Shinkansen on display in a museum outside of Japan. The 700T Series, operated by Taiwan High Speed Rail, is the first operational Shinkansen type exported outside Japan. Based on the 700 series, they were built by Kawasaki Heavy Industries and are operated as 12-car sets. They first entered service in January 2007, with a maximum speed of {{convert|300|km/h|mph|abbr=on}}.

The China Railway CRH2 is based on the E2-1000 series design. The trains are built by CSR Sifang Loco & Rolling stocks corporation under a license purchased in 2004 from a consortium formed of Kawasaki Heavy Industries, Mitsubishi Electric Corporation, and Hitachi. Trial services started in January 2007.

A retired 0 Series Shinkansen power car was donated to the National Railway Museum, in 2000.

Vietnam Railways was considering the use of Shinkansen technology for high-speed rail between the capital Hanoi and the southern commercial hub of Ho Chi Minh City, according to the Nihon Keizai Shimbun, citing an interview with Chief Executive Officer Nguyen Huu Bang. The Vietnamese government had already given basic approval for the Shinkansen system, although it still requires financing and formal consent from the prime minister. Vietnam rejected a funding proposal in 2010, so funding for the $56 billion project is uncertain. Hanoi was exploring additional Japanese funding Official Development Assistance as well as funds from the World Bank and Asian Development Bank. The {{convert|1560|km|mi|adj=on}} line would replace the current colonial-era rail line. Vietnam hoped to launch high-speed trains by 2020 and planned to start by building three sections, including a {{cvt|90|km|mi}} stretch between the central coastal cities of Da Nang and Huế, seen as potentially most profitable. Vietnam Railways had sent engineers to Central Japan Railway Company for technical training.{{cite web |date=13 August 2009 |title= |script-title=ja:ベトナム縦断で新幹線 国営鉄道会長、2020年部分開業目指す |trans-title=Shinkansen national railway chairman crosses Vietnam, aiming for partial opening in 2020 |url=http://www.nikkei.co.jp/news/kaigai/20090813AT2M1203A12082009.html |archive-url=https://web.archive.org/web/20090904043603/http://www.nikkei.co.jp/news/kaigai/20090813AT2M1203A12082009.html |archive-date=4 September 2009 |access-date=13 August 2009 |publisher=The Nikkei Net |language=ja}}{{cite web|url=https://www.google.com/hostednews/afp/article/ALeqM5gv5p5C0gfrQ43JZcXx7lZ39KyfTg |archive-url=https://web.archive.org/web/20090823063033/http://www.google.com/hostednews/afp/article/ALeqM5gv5p5C0gfrQ43JZcXx7lZ39KyfTg |archive-date=23 August 2009 |title=Vietnam plans Japanese bullet train link |publisher= AFP |date= 13 August 2009 |access-date=13 August 2009}}
