130-594: The Seikan Tunnel ( Japanese : 青函トンネル , Seikan Tonneru or 青函隧道 , Seikan Zuidō ) is a 53.85 km (33.46 mi) dual-gauge railway tunnel in Japan, with a 23.3 km (14.5 mi) portion under the seabed of the Tsugaru Strait , which separates Aomori Prefecture on the main Japanese island of Honshu from the northern island of Hokkaido . The track level is about 100 m (330 ft) below

260-558: 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

390-504: A world record 603 km/h (375 mph) for SCMaglev trains in April 2015. The original Tokaido Shinkansen, connecting Tokyo , Nagoya , and Osaka , three of Japan's largest cities, is one of the world's busiest high-speed rail lines. In the one-year period preceding March 2017, it carried 159 million passengers, and since its opening more than six decades ago, it has transported more than 6.4 billion total passengers. At peak times,

520-637: A benefit from the in-group to the out-group) means "[I/we] explained [it] to [him/her/them]". Such beneficiary auxiliary verbs thus serve a function comparable to that of pronouns and prepositions in Indo-European languages to indicate the actor and the recipient of an action. Japanese "pronouns" also function differently from most modern Indo-European pronouns (and more like nouns) in that they can take modifiers as any other noun may. For instance, one does not say in English: The amazed he ran down

650-519: A bullet 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 200 km/h (120 mph). 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

780-437: 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 400–520 mm (16–20 inches) in diameter and 200 mm (7.9 inches) high, are located at 5-metre intervals. The prefabricated upstands are made of either reinforced concrete or pre-stressed reinforced concrete; they prevent

910-488: A day. Including special trains, there are about 50 freight trains up and down. The effect of being able to achieve stable and safe transportation that is not affected by the weather has been significant, and in particular, the transportation volume of agricultural products, which are a key industry in Hokkaido, has increased dramatically. Connecting the islands Honshu and Hokkaido by a fixed link had been considered since

1040-544: 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

1170-414: A distinct language of its own that has absorbed various aspects from neighboring languages. Japanese has five vowels, and vowel length is phonemic, with each having both a short and a long version. Elongated vowels are usually denoted with a line over the vowel (a macron ) in rōmaji , a repeated vowel character in hiragana , or a chōonpu succeeding the vowel in katakana . /u/ ( listen )

1300-419: A glide /j/ and either the first part of a geminate consonant ( っ / ッ , represented as Q) or a moraic nasal in the coda ( ん / ン , represented as N). The nasal is sensitive to its phonetic environment and assimilates to the following phoneme, with pronunciations including [ɴ, m, n, ɲ, ŋ, ɰ̃] . Onset-glide clusters only occur at the start of syllables but clusters across syllables are allowed as long as

1430-505: A high ride quality and less electrical equipment. ) 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,

1560-484: A listener depending on the listener's relative social position and the degree of familiarity between the speaker and the listener. When used in different social relationships, the same word may have positive (intimate or respectful) or negative (distant or disrespectful) connotations. Japanese often use titles of the person referred to where pronouns would be used in English. For example, when speaking to one's teacher, it

1690-600: A low-interest loan of US$ 80 million from the World Bank . Initial estimates, however, were understated and the actual cost was about 380 billion yen. As the budget shortfall became clear in 1963, Sogo resigned to take responsibility. A test facility for rolling stock, called the Kamonomiya Model Section, opened in Odawara in 1962. The Tōkaidō Shinkansen began service on 1 October 1964, in time for

1820-614: A minimum curve radius of 4,000 m (13,123 ft) (2,500 m (8,202 ft) on the oldest Tōkaidō Shinkansen). The Shinkansen uses 1,435 mm ( 4 ft  8 + 1 ⁄ 2  in ) standard gauge in contrast to the 1,067 mm ( 3 ft 6 in ) 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

1950-682: A passenger committed suicide on board a Shinkansen train by setting himself on fire, killing another passenger and seriously injuring seven other people. There have been two derailments of Shinkansen trains in passenger service. The first one occurred during the Chūetsu earthquake on 23 October 2004 . Eight of ten cars of the Toki No. 325 train on the Jōetsu Shinkansen derailed near Nagaoka Station in Nagaoka, Niigata . There were no casualties among

2080-422: 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 . Shinkansen routes never intersect with slower, narrow-gauge conventional lines (except mini-shinkansen , which runs along these older lines). Consequently,

2210-408: A sentence need not be stated and pronouns may be omitted if they can be inferred from context. In the example above, hana ga nagai would mean "[their] noses are long", while nagai by itself would mean "[they] are long." A single verb can be a complete sentence: Yatta! ( やった! ) "[I / we / they / etc] did [it]!". In addition, since adjectives can form the predicate in a Japanese sentence (below),

2340-428: A single adjective can be a complete sentence: Urayamashii! ( 羨ましい! ) "[I'm] jealous [about it]!". While the language has some words that are typically translated as pronouns, these are not used as frequently as pronouns in some Indo-European languages, and function differently. In some cases, Japanese relies on special verb forms and auxiliary verbs to indicate the direction of benefit of an action: "down" to indicate

2470-407: A single main tunnel. However, for the 23.3-kilometre (14.5 mi) undersea portion, three bores were excavated with increasing diameters respectively: an initial pilot tunnel, a service tunnel, and finally the main tunnel. The service tunnel was periodically connected to the main tunnel with a series of connecting drifts , at 600–1,000-metre (1,969–3,281 ft) intervals. The pilot tunnel serves as

2600-400: A standard-gauge rail has a curve with a maximum speed of 145 km/h (90 mph), the same curve on narrow-gauge rail will have a maximum allowable speed of 130 km/h (81 mph). 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

2730-447: A switch that set off a blast that completed the pilot tunnel . Similarly on 10 March 1985, Minister of Transport Tokuo Yamashita symbolically bored through the main tunnel. The necessity for the project was questioned at times during construction, as the 1971 traffic predictions were overestimates. Instead of the traffic rate increasing as predicted to a peak in 1985, it peaked earlier in 1978 and then proceeded to decrease. The decrease

2860-621: A trainset in order to perform high-speed tests. 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. 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. However, Shinji Sogō , President of Japanese National Railways , insisted strongly on

2990-596: A tunnel setting. If successful, it will allow the Hokkaido Shinkansen to travel at full speed inside the tunnel in the future. As of March 2019, Shinkansen trains operate through the tunnel to Shin-Hakodate-Hokuto Station in Hakodate , connecting Tokyo and Shin-Hakodate-Hokuto stations in 3 hours and 58 minutes, at a maximum speed of 160 km/h (100 mph) within the tunnel and 260 km/h (160 mph) outside it, and 320 km/h (200 mph) to

3120-624: Is compressed rather than protruded , or simply unrounded. Some Japanese consonants have several allophones , which may give the impression of a larger inventory of sounds. However, some of these allophones have since become phonemic. For example, in the Japanese language up to and including the first half of the 20th century, the phonemic sequence /ti/ was palatalized and realized phonetically as [tɕi] , approximately chi ( listen ) ; however, now [ti] and [tɕi] are distinct, as evidenced by words like tī [tiː] "Western-style tea" and chii [tɕii] "social status". The "r" of

3250-421: Is topic–comment . Sentence-final particles are used to add emotional or emphatic impact, or form questions. Nouns have no grammatical number or gender , and there are no articles . Verbs are conjugated , primarily for tense and voice , but not person . Japanese adjectives are also conjugated. Japanese has a complex system of honorifics , with verb forms and vocabulary to indicate the relative status of

3380-448: Is also seen in o-medetō "congratulations", from medetaku ). Late Middle Japanese has the first loanwords from European languages – now-common words borrowed into Japanese in this period include pan ("bread") and tabako ("tobacco", now "cigarette"), both from Portuguese . Modern Japanese is considered to begin with the Edo period (which spanned from 1603 to 1867). Since Old Japanese,

3510-527: Is also used in a limited fashion (such as for imported acronyms) in Japanese writing. The numeral system uses mostly Arabic numerals , but also traditional Chinese numerals . Proto-Japonic , the common ancestor of the Japanese and Ryukyuan languages , is thought to have been brought to Japan by settlers coming from the Korean peninsula sometime in the early- to mid-4th century BC (the Yayoi period ), replacing

3640-440: Is appropriate to use sensei ( 先生 , "teacher"), but inappropriate to use anata . This is because anata is used to refer to people of equal or lower status, and one's teacher has higher status. Japanese nouns have no grammatical number, gender or article aspect. The noun hon ( 本 ) may refer to a single book or several books; hito ( 人 ) can mean "person" or "people", and ki ( 木 ) can be "tree" or "trees". Where number

3770-701: Is associated with comedy (see Kansai dialect ). Dialects of Tōhoku and North Kantō are associated with typical farmers. The Ryūkyūan languages, spoken in Okinawa and the Amami Islands (administratively part of Kagoshima ), are distinct enough to be considered a separate branch of the Japonic family; not only is each language unintelligible to Japanese speakers, but most are unintelligible to those who speak other Ryūkyūan languages. However, in contrast to linguists, many ordinary Japanese people tend to consider

3900-466: Is better documentation of Late Middle Japanese phonology than for previous forms (for instance, the Arte da Lingoa de Iapam ). Among other sound changes, the sequence /au/ merges to /ɔː/ , in contrast with /oː/ ; /p/ is reintroduced from Chinese; and /we/ merges with /je/ . Some forms rather more familiar to Modern Japanese speakers begin to appear – the continuative ending - te begins to reduce onto

4030-509: Is correlated with the sex of the speaker and the social situation in which they are spoken: men and women alike in a formal situation generally refer to themselves as watashi ( 私 , literally "private") or watakushi (also 私 , hyper-polite form), while men in rougher or intimate conversation are much more likely to use the word ore ( 俺 "oneself", "myself") or boku . Similarly, different words such as anata , kimi , and omae ( お前 , more formally 御前 "the one before me") may refer to

4160-417: Is important, it can be indicated by providing a quantity (often with a counter word ) or (rarely) by adding a suffix, or sometimes by duplication (e.g. 人人 , hitobito , usually written with an iteration mark as 人々 ). Words for people are usually understood as singular. Thus Tanaka-san usually means Mx Tanaka . Words that refer to people and animals can be made to indicate a group of individuals through

4290-755: Is less common. In terms of mutual intelligibility , a survey in 1967 found that the four most unintelligible dialects (excluding Ryūkyūan languages and Tōhoku dialects ) to students from Greater Tokyo were the Kiso dialect (in the deep mountains of Nagano Prefecture ), the Himi dialect (in Toyama Prefecture ), the Kagoshima dialect and the Maniwa dialect (in Okayama Prefecture ). The survey

4420-722: 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: The following lines are under construction. These lines except Chūō Shinkansen , called Seibi Shinkansen  [ ja ] or planned Shinkansen , are

4550-420: Is often called a topic-prominent language , which means it has a strong tendency to indicate the topic separately from the subject, and that the two do not always coincide. The sentence Zō wa hana ga nagai ( 象は鼻が長い ) literally means, "As for elephant(s), (the) nose(s) (is/are) long". The topic is zō "elephant", and the subject is hana "nose". Japanese grammar tends toward brevity; the subject or object of

4680-498: Is preserved in words such as matsuge ("eyelash", lit. "hair of the eye"); modern mieru ("to be visible") and kikoeru ("to be audible") retain a mediopassive suffix - yu(ru) ( kikoyu → kikoyuru (the attributive form, which slowly replaced the plain form starting in the late Heian period) → kikoeru (all verbs with the shimo-nidan conjugation pattern underwent this same shift in Early Modern Japanese )); and

4810-665: Is the principal language of the Japonic language family spoken by the Japanese people . It has around 123 million speakers, primarily in Japan , the only country where it is the national language , and within the Japanese diaspora worldwide. The Japonic family also includes the Ryukyuan languages and the variously classified Hachijō language . There have been many attempts to group the Japonic languages with other families such as

4940-402: Is the version of Japanese discussed in this article. Formerly, standard Japanese in writing ( 文語 , bungo , "literary language") was different from colloquial language ( 口語 , kōgo ) . The two systems have different rules of grammar and some variance in vocabulary. Bungo was the main method of writing Japanese until about 1900; since then kōgo gradually extended its influence and

5070-471: Is used for the present and the future. For verbs that represent an ongoing process, the -te iru form indicates a continuous (or progressive) aspect , similar to the suffix ing in English. For others that represent a change of state, the -te iru form indicates a perfect aspect. For example, kite iru means "They have come (and are still here)", but tabete iru means "They are eating". Questions (both with an interrogative pronoun and yes/no questions) have

5200-437: Is used to describe both the railway lines the trains run on and the trains themselves. In English, the trains are also known as the bullet train. The term bullet train ( 弾丸列車 , dangan ressha ) originates from 1939, and was the initial name given to the Shinkansen project in its earliest planning stages. Furthermore, the name super express ( 超特急 , chō-tokkyū ) , used exclusively until 1972 for Hikari trains on

5330-431: 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%. However, the smaller diameter of Shinkansen tunnels, compared to some other high-speed lines, has resulted in the issue of tunnel boom becoming

5460-405: Is why some linguists do not classify Japanese "pronouns" as pronouns, but rather as referential nouns, much like Spanish usted (contracted from vuestra merced , "your ( majestic plural ) grace") or Portuguese você (from vossa mercê ). Japanese personal pronouns are generally used only in situations requiring special emphasis as to who is doing what to whom. The choice of words used as pronouns

5590-679: The 0 series , ran at speeds of up to 210 km/h (130 mph), later increased to 220 km/h (137 mph). 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. The Tōkaidō Shinkansen's rapid success prompted an extension westward to Okayama , Hiroshima and Fukuoka (the San'yō Shinkansen ), which

5720-563: The Ainu , Austronesian , Koreanic , and the now-discredited Altaic , but none of these proposals have gained any widespread acceptance. Little is known of the language's prehistory, or when it first appeared in Japan. Chinese documents from the 3rd century AD recorded a few Japanese words, but substantial Old Japanese texts did not appear until the 8th century. From the Heian period (794–1185), extensive waves of Sino-Japanese vocabulary entered

5850-462: The Japonic language family, which also includes the Ryukyuan languages spoken in the Ryukyu Islands . As these closely related languages are commonly treated as dialects of the same language, Japanese is sometimes called a language isolate . According to Martine Irma Robbeets , Japanese has been subject to more attempts to show its relation to other languages than any other language in

5980-761: 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. Many Shinkansen lines were proposed during the boom of the early 1970s but have yet to be constructed and have subsequently been shelved indefinitely. In addition,

6110-540: The Neogene period. The western neck was selected, with its conditions considered favourable for tunnelling. The geology of the undersea portion of the tunnel consists of volcanic rock, pyroclastic rock , as well as sedimentary rock of the Neogene period. The area is folded into a nearly vertical syncline , which means that the youngest rock is in the centre of the strait and encountered last. Divided roughly into thirds,

6240-514: The Philippines , and various Pacific islands, locals in those countries learned Japanese as the language of the empire. As a result, many elderly people in these countries can still speak Japanese. Japanese emigrant communities (the largest of which are to be found in Brazil , with 1.4 million to 1.5 million Japanese immigrants and descendants, according to Brazilian IBGE data, more than

6370-585: The Taishō period (1912–25), but serious surveying commenced only in 1946, induced by the loss of overseas territory at the end of World War II and the need to accommodate returnees. In 1954, five ferries, including the Tōya Maru , sank in the Tsugaru Strait during a typhoon, killing 1,430 passengers. The following year, Japanese National Railways (JNR) expedited the tunnel feasibility study. Also of concern

6500-497: The Tokaido Shinkansen (515.4 km; 320.3 mi) in 1964, the network has expanded to consist of 2,951.3 km (1,833.9 mi) of lines with maximum speeds of 260–320 km/h (160–200 mph), 283.5 km (176.2 mi) of Mini-shinkansen lines with a maximum speed of 130 km/h (80 mph), and 10.3 km (6.4 mi) of spur lines with Shinkansen services. The network links most major cities on

6630-602: 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. Following the end of World War II, high-speed rail was forgotten for several years while traffic of passengers and freight steadily increased on

6760-756: 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. 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 set a world speed record of 603 km/h (375 mph). To enable high-speed operation, Shinkansen uses

6890-584: The Tōkaidō Shinkansen , is used today in English-language announcements and signage. Japan was the first country to build dedicated railway lines for high-speed travel. Because of the mountainous terrain, the existing network consisted of 1,067 mm ( 3 ft 6 in ) 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

7020-738: The United States (notably in Hawaii , where 16.7% of the population has Japanese ancestry, and California ), and the Philippines (particularly in Davao Region and the Province of Laguna ). Japanese has no official status in Japan, but is the de facto national language of the country. There is a form of the language considered standard : hyōjungo ( 標準語 ) , meaning "standard Japanese", or kyōtsūgo ( 共通語 ) , "common language", or even "Tokyo dialect" at times. The meanings of

7150-553: The bullet train , is a network of high-speed railway lines in Japan . It was initially built to connect distant Japanese regions with Tokyo , the capital, to aid economic growth and development. Beyond long-distance travel, some sections around the largest metropolitan areas are used as a commuter rail network. It is owned by the Japan Railway Construction, Transport and Technology Agency and operated by five Japan Railways Group companies. Starting with

7280-806: The de facto standard Japanese had been the Kansai dialect , especially that of Kyoto . However, during the Edo period, Edo (now Tokyo) developed into the largest city in Japan, and the Edo-area dialect became standard Japanese. Since the end of Japan's self-imposed isolation in 1853, the flow of loanwords from European languages has increased significantly. The period since 1945 has seen many words borrowed from other languages—such as German, Portuguese and English. Many English loan words especially relate to technology—for example, pasokon (short for "personal computer"), intānetto ("internet"), and kamera ("camera"). Due to

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

7670-527: The 1.2 million of the United States ) sometimes employ Japanese as their primary language. Approximately 12% of Hawaii residents speak Japanese, with an estimated 12.6% of the population of Japanese ancestry in 2008. Japanese emigrants can also be found in Peru , Argentina , Australia (especially in the eastern states), Canada (especially in Vancouver , where 1.4% of the population has Japanese ancestry),

7800-654: The 154 passengers. Another derailment happened on 2 March 2013 on the Akita Shinkansen when the Komachi No. 25 train derailed in blizzard conditions in Daisen, Akita . No passengers were injured. 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. New anti-derailment devices were installed on tracks after analysis of

7930-571: The Basic Plan specified that the Jōetsu Shinkansen should start from Shinjuku , not Tokyo Station , which would have required building an additional 30 km (19 mi) 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

Igneous intrusions and faults caused crushing of the rock and complicated the tunnelling procedures. Initial geological investigation occurred from 1946 to 1963, which involved drilling

8190-486: The Japanese language is of particular interest, ranging between an apical central tap and a lateral approximant . The "g" is also notable; unless it starts a sentence, it may be pronounced [ ŋ ] , in the Kanto prestige dialect and in other eastern dialects. The phonotactics of Japanese are relatively simple. The syllable structure is (C)(G)V(C), that is, a core vowel surrounded by an optional onset consonant,

8320-523: The L0 series could be a passenger train. 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. In 2016, JR Central reported that the Shinkansen's average delay from schedule per train was 24 seconds. This includes delays due to uncontrollable causes, such as natural disasters. Over

8450-736: The Old Japanese sections are written in Man'yōgana , which uses kanji for their phonetic as well as semantic values. Based on the Man'yōgana system, Old Japanese can be reconstructed as having 88 distinct morae . Texts written with Man'yōgana use two different sets of kanji for each of the morae now pronounced き (ki), ひ (hi), み (mi), け (ke), へ (he), め (me), こ (ko), そ (so), と (to), の (no), も (mo), よ (yo) and ろ (ro). (The Kojiki has 88, but all later texts have 87. The distinction between mo 1 and mo 2 apparently

8580-488: The Ryūkyūan languages as dialects of Japanese. The imperial court also seems to have spoken an unusual variant of the Japanese of the time, most likely the spoken form of Classical Japanese , a writing style that was prevalent during the Heian period , but began to decline during the late Meiji period . The Ryūkyūan languages are classified by UNESCO as 'endangered', as young people mostly use Japanese and cannot understand

8710-549: 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. The succeeding minister has not indicated whether this proposal remains supported. While

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

8970-500: The Shinkansen's 60-plus year history, carrying over 10 billion passengers, there have been no passenger fatalities due to train accidents such as derailments or collisions, despite frequent earthquakes and typhoons. Injuries and a single fatality have been caused by doors closing on passengers or their belongings; attendants are employed at platforms to prevent such accidents. There have, however, been suicides by passengers jumping both from and in front of moving trains. On 30 June 2015,

9100-529: 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

9230-543: The addition of a collective suffix (a noun suffix that indicates a group), such as -tachi , but this is not a true plural: the meaning is closer to the English phrase "and company". A group described as Tanaka-san-tachi may include people not named Tanaka. Some Japanese nouns are effectively plural, such as hitobito "people" and wareware "we/us", while the word tomodachi "friend" is considered singular, although plural in form. Verbs are conjugated to show tenses, of which there are two: past and present (or non-past) which

9360-444: The construction of the Hokkaido Shinkansen, both stations contained museums detailing the history and function of the tunnel that could be visited on special sightseeing tours. The museums are now closed and the space provides storage for work on the Hokkaido Shinkansen. The two were the first railway stations in the world built under the sea. Japanese language Japanese ( 日本語 , Nihongo , [ɲihoŋɡo] )

9490-599: 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

9620-654: The construction was 34. Unlike the start of construction during the heyday of the Seikan route, even in eastern Japan, passenger traffic to Hokkaido was already dominated by aircraft, and the construction of the Hokkaido Shinkansen was frozen when it was completed. On the freight side, due to the deterioration of labor-management relations at the JNR at the time, including the frequent strikes and legal compliance struggles, freight transportation continued to stagnate as it lost market share to ferries and coastal shipping. In addition, since

9750-532: 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 145 km/h (90 mph) for a narrow gauge train when JNR leased

9880-535: 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

10010-578: The effect of changing Japanese into a mora-timed language. Late Middle Japanese covers the years from 1185 to 1600, and is normally divided into two sections, roughly equivalent to the Kamakura period and the Muromachi period , respectively. The later forms of Late Middle Japanese are the first to be described by non-native sources, in this case the Jesuit and Franciscan missionaries; and thus there

10140-735: 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. 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. Lght freight has been carried on some passenger services since 2019, and there are plans to expand this with freight-only trains in

10270-455: The flow of loanwords from European languages increased significantly, and words from English roots have proliferated. Japanese is an agglutinative , mora -timed language with relatively simple phonotactics , a pure vowel system, phonemic vowel and consonant length, and a lexically significant pitch-accent . Word order is normally subject–object–verb with particles marking the grammatical function of words, and sentence structure

10400-904: The future. 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: Trains are up to sixteen cars long. With each car measuring 25 m (82 ft) in length, the longest trains are 400 m ( 1 ⁄ 4  mile) end to end. Stations are similarly long to accommodate these trains. Some of Japan's high-speed maglev trains are considered Shinkansen, while other slower maglev trains (such as Linimo , serving local communities in and nearby Nagoya , Aichi Prefecture ) are intended as alternatives to conventional urban rapid transit systems. These trains were and are used only for experimental runs, though

10530-609: The genitive particle ga remains in intentionally archaic speech. Early Middle Japanese is the Japanese of the Heian period , from 794 to 1185. It formed the basis for the literary standard of Classical Japanese , which remained in common use until the early 20th century. During this time, Japanese underwent numerous phonological developments, in many cases instigated by an influx of Chinese loanwords . These included phonemic length distinction for both consonants and vowels , palatal consonants (e.g. kya ) and labial consonant clusters (e.g. kwa ), and closed syllables . This had

10660-461: The high cost of building the Shinkansen network. By the early 1980s, the company was practically insolvent, 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 320 km/h (200 mph) on

10790-465: The islands of Honshu and Kyushu , and connects to Hakodate on the northern island of Hokkaido . An extension to Sapporo is under construction and scheduled to open in March 2031. The maximum operating speed is 320 km/h (200 mph) (on a 387.5 km (241 mi) section of the Tōhoku Shinkansen ). Test runs have reached 443 km/h (275 mph) for conventional rail in 1996, and up to

10920-535: The journey is 1 hour and 45 minutes, or 3 hours and 30 minutes including airport access times. Deregulation and competition in Japanese domestic air travel has brought down prices on the Tokyo-Sapporo route, making rail more expensive in comparison. The Hokutosei overnight train service began after the completion of the Seikan Tunnel; a later and more luxurious Cassiopeia overnight train service

11050-430: The language, affecting the phonology of Early Middle Japanese . Late Middle Japanese (1185–1600) saw extensive grammatical changes and the first appearance of European loanwords . The basis of the standard dialect moved from the Kansai region to the Edo region (modern Tokyo ) in the Early Modern Japanese period (early 17th century–mid 19th century). Following the end of Japan's self-imposed isolation in 1853,

11180-458: The languages of the original Jōmon inhabitants, including the ancestor of the modern Ainu language . Because writing had yet to be introduced from China, there is no direct evidence, and anything that can be discerned about this period must be based on internal reconstruction from Old Japanese , or comparison with the Ryukyuan languages and Japanese dialects . The Chinese writing system

11310-449: The languages. Okinawan Japanese is a variant of Standard Japanese influenced by the Ryūkyūan languages, and is the primary dialect spoken among young people in the Ryukyu Islands . Modern Japanese has become prevalent nationwide (including the Ryūkyū islands) due to education , mass media , and an increase in mobility within Japan, as well as economic integration. Japanese is a member of

11440-427: The large quantity of English loanwords, modern Japanese has developed a distinction between [tɕi] and [ti] , and [dʑi] and [di] , with the latter in each pair only found in loanwords. Although Japanese is spoken almost exclusively in Japan, it has also been spoken outside of the country. Before and during World War II , through Japanese annexation of Taiwan and Korea , as well as partial occupation of China ,

11570-658: The line carries up to 16 trains per hour in each direction with 16 cars each (1,323-seat capacity and occasionally additional standing passengers) with a minimum headway of three minutes between trains. The Shinkansen network of Japan had the highest annual passenger ridership (a maximum of 386 million in 2007) of any high-speed rail network until 2011, when the Chinese high-speed railway network surpassed it at 370 million passengers annually, reaching over 2.9 billion annual passengers in 2023. Shinkansen ( 新幹線 ) in Japanese means 'new trunk line' or 'new main line', but this word

11700-508: The maintenance cost is large, such as the need to pump a large amount of spring water even after completion, even a huge investment is regarded as a sunk cost, and it is said that it is more economical to abandon it, and it was ridiculed variously as " Showa's Three Idiots Assessment ", "useless long things", and "quagmire tunnel". However, after its opening, it has played an important role in freight transportation by JR Freight between Hokkaido and Honshu, and has made 21 round trips (regular trains)

11830-455: 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,

11960-767: The nearest major city on the Hokkaido side. The Seikan Tunnel is the world's longest undersea tunnel by overall length (the Channel Tunnel , while shorter, has a longer undersea segment). It is also the second-deepest transport tunnel below sea level after the Ryfylke Tunnel , a road tunnel in Norway that opened in 2019, and the second longest main-line railway tunnel after the Gotthard Base Tunnel in Switzerland, opened in 2016. The tunnel

12090-425: The only strict rule of word order is that the verb must be placed at the end of a sentence (possibly followed by sentence-end particles). This is because Japanese sentence elements are marked with particles that identify their grammatical functions. The basic sentence structure is topic–comment . For example, Kochira wa Tanaka-san desu ( こちらは田中さんです ). kochira ("this") is the topic of the sentence, indicated by

12220-470: The out-group gives a benefit to the in-group, and "up" to indicate the in-group gives a benefit to the out-group. Here, the in-group includes the speaker and the out-group does not, and their boundary depends on context. For example, oshiete moratta ( 教えてもらった ) (literally, "explaining got" with a benefit from the out-group to the in-group) means "[he/she/they] explained [it] to [me/us]". Similarly, oshiete ageta ( 教えてあげた ) (literally, "explaining gave" with

12350-415: The particle wa . The verb desu is a copula , commonly translated as "to be" or "it is" (though there are other verbs that can be translated as "to be"), though technically it holds no meaning and is used to give a sentence 'politeness'. As a phrase, Tanaka-san desu is the comment. This sentence literally translates to "As for this person, (it) is Mx Tanaka." Thus Japanese, like many other Asian languages,

12480-599: 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

12610-458: The possibility of high-speed rail , and the Shinkansen project was implemented. 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, which was raised in the form of a government loan, railway bonds and

12740-481: The proposed larger Altaic family, or to various Southeast Asian languages , especially Austronesian . None of these proposals have gained wide acceptance (and the Altaic family itself is now considered controversial). As it stands, only the link to Ryukyuan has wide support. Other theories view the Japanese language as an early creole language formed through inputs from at least two distinct language groups, or as

12870-459: The same structure as affirmative sentences, but with intonation rising at the end. In the formal register, the question particle -ka is added. For example, ii desu ( いいです ) "It is OK" becomes ii desu-ka ( いいですか。 ) "Is it OK?". In a more informal tone sometimes the particle -no ( の ) is added instead to show a personal interest of the speaker: Dōshite konai-no? "Why aren't (you) coming?". Some simple queries are formed simply by mentioning

13000-416: The sea-bed, sonic surveys , submarine boring, observations using a mini-submarine, as well as seismic and magnetic surveys. To establish a greater understanding, a horizontal pilot boring was undertaken along the line of the service and main tunnels. Tunnelling occurred simultaneously from the northern end and the southern. The dry land portions were tackled with traditional mountain tunnelling techniques, with

13130-548: The seabed and 240 m (790 ft) below sea level. The tunnel is part of the standard-gauge Hokkaido Shinkansen and the narrow-gauge Kaikyō Line of the Hokkaido Railway Company (JR Hokkaido)'s Tsugaru-Kaikyō Line . The name Seikan comes from combining the on'yomi readings of the first characters of Aomori ( 青森 ) , the nearest major city on the Honshu side of the strait, and Hakodate ( 函館 ) ,

13260-412: The service tunnel for the central five-kilometre portion. Beneath the Tsugaru Strait, the use of a tunnel boring machine (TBM) was abandoned after less than two kilometres (1.2 miles) owing to the variable nature of the rock and difficulty in accessing the face for advanced grouting. Blasting with dynamite and mechanical picking were then used to excavate. A 2002 report by Michitsugu Ikuma described, for

13390-635: The shinkansen is not affected by slower local or freight trains (except for Hokkaido Shinkansen while traveling through the Seikan Tunnel ), and has the capacity to operate many high-speed trains punctually. In addition, shinkansen routes (excluding mini-shinkansen) are completely grade separated from roads and highways, meaning railway crossings are almost eliminated. Tracks are strictly off-limits with penalties against trespassing strictly regulated by law. The routes use tunnels and viaducts to go through and over obstacles rather than around them, with

13520-431: The south of Morioka. It was expected that by 2018 one daily service will be run at 260 km/h (160 mph) through the tunnel. The final stage is proposed to open to Sapporo Station in 2031 and is expected to shorten the Tokyo-Sapporo rail journey to five hours. The Hokkaido Shinkansen will be operated by JR Hokkaido . Surveying started in 1946 and construction began in 1971. By August 1982, less than 700 metres of

13650-439: The speaker, the listener, and persons mentioned. The Japanese writing system combines Chinese characters , known as kanji ( 漢字 , ' Han characters') , with two unique syllabaries (or moraic scripts) derived by the Japanese from the more complex Chinese characters: hiragana ( ひらがな or 平仮名 , 'simple characters') and katakana ( カタカナ or 片仮名 , 'partial characters'). Latin script ( rōmaji ローマ字 )

13780-817: The state as at the time the constitution was written, many of the elders participating in the process had been educated in Japanese during the South Seas Mandate over the island shown by the 1958 census of the Trust Territory of the Pacific that found that 89% of Palauans born between 1914 and 1933 could speak and read Japanese, but as of the 2005 Palau census there were no residents of Angaur that spoke Japanese at home. Japanese dialects typically differ in terms of pitch accent , inflectional morphology , vocabulary , and particle usage. Some even differ in vowel and consonant inventories, although this

13910-481: The street. (grammatically incorrect insertion of a pronoun) But one can grammatically say essentially the same thing in Japanese: 驚いた彼は道を走っていった。 Transliteration: Odoroita kare wa michi o hashitte itta. (grammatically correct) This is partly because these words evolved from regular nouns, such as kimi "you" ( 君 "lord"), anata "you" ( あなた "that side, yonder"), and boku "I" ( 僕 "servant"). This

14040-407: The technical development of the first line, the Tōkaidō Shinkansen . All three had worked on aircraft design during World War II . The popular English name bullet train is a literal translation of the Japanese term 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

14170-683: The topic with an interrogative intonation to call for the hearer's attention: Kore wa? "(What about) this?"; O-namae wa? ( お名前は? ) "(What's your) name?". Negatives are formed by inflecting the verb. For example, Pan o taberu ( パンを食べる。 ) "I will eat bread" or "I eat bread" becomes Pan o tabenai ( パンを食べない。 ) "I will not eat bread" or "I do not eat bread". Plain negative forms are i -adjectives (see below) and inflect as such, e.g. Pan o tabenakatta ( パンを食べなかった。 ) "I did not eat bread". Shinkansen The Shinkansen ( Japanese : 新幹線 , [ɕiŋkaꜜɰ̃seɴ] , lit.   ' new trunk line ' ) , colloquially known in English as

14300-508: 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. This larger loading gauge permits wider coaches, allowing for 5-abreast seating (2+3) in Standard Class coaches, compared to

14430-708: The track slab from moving latitudinally or longitudinally. One track slab weighs approximately 5 tons and is 2,220–2,340 mm (87–92 inches) wide, 4,900–4,950 mm (193–195 inches) long and 160–200 mm (6.3–7.9 inches) thick. 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

14560-431: The tunnel remained to be excavated. First contact between the two sides was in 1983. The Tsugaru Strait has eastern and western necks, both approximately 20 km (12 mi) across. Initial surveys undertaken in 1946 indicated that the eastern neck was up to 200 metres (656 feet) deep with volcanic geology. The western neck had a maximum depth of 140 metres (459 feet) and geology consisting mostly of sedimentary rocks of

14690-489: The tunnel was issued by the Japan Mint in 1988. Once the tunnel was completed, all railway transport between Honshu and Hokkaido used it. However, for passenger transport, 90% of people use air travel due to the speed and cost. For example, to travel between Tokyo and Sapporo by train takes eight hours (Tokyo station and Shin-Sapporo station), with transfer from Shinkansen to narrow-gauge express train at Hakodate. By air,

14820-458: The tunnel— Tappi-Kaitei Station and Yoshioka-Kaitei Station . They serve as emergency escape points. In the event of a fire or other disaster, the stations provide the equivalent safety of a much shorter tunnel. The effectiveness of the escape shafts at the emergency stations is enhanced by having exhaust fans to extract smoke, television cameras to help route passengers to safety, thermal (infrared) fire alarm systems, and water spray nozzles. Before

14950-419: The two consonants are the moraic nasal followed by a homorganic consonant. Japanese also includes a pitch accent , which is not represented in moraic writing; for example [haꜜ.ɕi] ("chopsticks") and [ha.ɕiꜜ] ("bridge") are both spelled はし ( hashi ) , and are only differentiated by the tone contour. Japanese word order is classified as subject–object–verb . Unlike many Indo-European languages ,

15080-577: The two methods were both used in writing until the 1940s. Bungo still has some relevance for historians, literary scholars, and lawyers (many Japanese laws that survived World War II are still written in bungo , although there are ongoing efforts to modernize their language). Kōgo is the dominant method of both speaking and writing Japanese today, although bungo grammar and vocabulary are occasionally used in modern Japanese for effect. The 1982 state constitution of Angaur , Palau , names Japanese along with Palauan and English as an official language of

15210-480: The two terms (''hyōjungo'' and ''kyōtsūgo'') are almost the same. Hyōjungo or kyōtsūgo is a conception that forms the counterpart of dialect. This normative language was born after the Meiji Restoration ( 明治維新 , meiji ishin , 1868) from the language spoken in the higher-class areas of Tokyo (see Yamanote ). Hyōjungo is taught in schools and used on television and in official communications. It

15340-468: The undersea section, that "the tunnel structure appears to remain in a good condition." The amount of inflow has been decreasing with time, although it "increases right after a large earthquake". In March 2018 at 30 years of age, maintenance costs amounted to 30 billion Yen or US$ 286 million since 1999. Plans are to increase speed and provide mobile communication at the full track. Initially, only 1,067 mm ( 3 ft 6 in ) narrow-gauge track

15470-407: The verb (e.g. yonde for earlier yomite ), the -k- in the final mora of adjectives drops out ( shiroi for earlier shiroki ); and some forms exist where modern standard Japanese has retained the earlier form (e.g. hayaku > hayau > hayɔɔ , where modern Japanese just has hayaku , though the alternative form is preserved in the standard greeting o-hayō gozaimasu "good morning"; this ending

15600-548: The world. Since Japanese first gained the consideration of linguists in the late 19th century, attempts have been made to show its genealogical relation to languages or language families such as Ainu , Korean , Chinese , Tibeto-Burman , Uralic , Altaic (or Ural-Altaic ), Austroasiatic , Austronesian and Dravidian . At the fringe, some linguists have even suggested a link to Indo-European languages , including Greek , or to Sumerian . Main modern theories try to link Japanese either to northern Asian languages, like Korean or

15730-684: 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. 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. The first Shinkansen trains,

15860-435: Was attributed to the slowdown in Japan's economy since the first oil crisis in 1973 and to advances made in air transport facilities and longer-range sea transport. The tunnel was opened on 13 March 1988, having cost a total of ¥ 1.1 trillion (US$ 7 billion) to construct, almost 12 times the original budget, much of which was due to inflation over the years. To commemorate the event, a commemorative 500 yen coin depicting

15990-539: Was based on 12- to 20-second-long recordings of 135 to 244 phonemes , which 42 students listened to and translated word-for-word. The listeners were all Keio University students who grew up in the Kanto region . There are some language islands in mountain villages or isolated islands such as Hachijō-jima island , whose dialects are descended from Eastern Old Japanese . Dialects of the Kansai region are spoken or known by many Japanese, and Osaka dialect in particular

16120-410: Was completed in 1975. 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

16250-450: Was constructed using conventional construction methods, including tunnel boring machine (TBM) and New Austrian tunneling method (NATM). The construction cost of the tunnel itself was 538.4 billion yen at the planning stage, but it actually cost 745.5 billion yen. The construction cost of the strait line, including the attachment line, was 689 billion yen at the planning stage, but ended up costing 900 billion yen. The number of fatalities in

16380-735: Was imported to Japan from Baekje around the start of the fifth century, alongside Buddhism. The earliest texts were written in Classical Chinese , although some of these were likely intended to be read as Japanese using the kanbun method, and show influences of Japanese grammar such as Japanese word order. The earliest text, the Kojiki , dates to the early eighth century, and was written entirely in Chinese characters, which are used to represent, at different times, Chinese, kanbun , and Old Japanese. As in other texts from this period,

16510-576: Was laid through the tunnel, but in 2005 the Hokkaido Shinkansen project started construction which included laying dual gauge track (providing standard gauge track capability) and extending the Shinkansen network through the tunnel. Shinkansen services to Hakodate commenced in March 2016, and are proposed to be extended to Sapporo by 2031. The tunnel has 52 km (32 mi) of continuous welded rail . Two stations are within

16640-474: Was lost immediately following its composition.) This set of morae shrank to 67 in Early Middle Japanese , though some were added through Chinese influence. Man'yōgana also has a symbol for /je/ , which merges with /e/ before the end of the period. Several fossilizations of Old Japanese grammatical elements remain in the modern language – the genitive particle tsu (superseded by modern no )

16770-554: Was often fully booked. Both were withdrawn following the commencement of Hokkaido Shinkansen services (in August 2015 and March 2016 respectively), with freight trains being the only regular service utilising the narrow-gauge line since that time. JR Hokkaido is exploring the use of " Train on Train " technology to remove the threat that the shock wave created in front of Shinkansen trains traveling at full speed poses to freight trains operating on Japanese standard narrow-gauge track in

16900-676: Was the increasing traffic between the two islands. A booming economy saw traffic levels on the JNR-operated Seikan Ferry double to 4,040,000 passengers/year from 1955 to 1965, and cargo levels rose 1.7 times to 6,240,000 tonnes/year. In September 1971, the decision was made to commence work on the tunnel. A Shinkansen -capable cross section was selected, with plans to extend the Shinkansen network. Arduous construction in difficult geological conditions proceeded. Thirty-four workers were killed during construction. On 27 January 1983, Japanese Prime Minister Yasuhiro Nakasone pressed
