Standardization: Why Tokyo-Standard Japanese Dominates
Tokyo Japanese became the standard because of policy, not nature. The standard variety, 標準語 (hyōjungo, "standard Japanese"), was established after the Meiji Restoration of 1868 on the basis of educated Tokyo speech. It is a political and historical product, not a linguistically privileged default.1 Understanding how the standard was built, and how the field later split 標準語 from 共通語 (kyōtsūgo, "common language"), changes how a learner reads every dialect map of Japan.
Overview
Before the Meiji period (1868–1912), the idea of a single, unified Japanese language did not exist. The need for a national language arose only as Japan was building itself into a modern nation-state and empire.2 Under the Tokugawa shogunate (1603–1867), the country was divided into roughly 250 semi-autonomous domains (藩, han), each with its own local speech. Linguistic diversity, not uniformity, was the pre-Meiji baseline.3
Shibatani frames the selection of the standard as driven by political and administrative motivation, not by any linguistic superiority of one variety over another.1
"Standard" is a choice, not a given
The historian of linguistics Lee Yeounsuk argues that 国語 (kokugo, "national language") was an invented ideology of the modern state, not the discovery of a pre-existing national tongue.2 That frame runs through this whole article. Standardization was nation-building, and it also functioned as suppression. It was not neutral progress.
The Meiji nation-building drive
After the Meiji Restoration of 1868, the new state pursued a standardized 国語 to support compulsory education, military conscription, and centralized administration. This followed the European nation-state model of one nation and one language.3 The formation of a Japanese nation-state with a single unifying language triggered the assimilation of regional varieties (方言, hōgen, "dialects") under the newly created standard national language.4
One nation, one language (国語)
Lee identifies the linguist Ueda Kazutoshi (上田万年, 1867–1937) as central to the creation of 国語 as a nation-building ideology. Hoshina Kōichi (保科孝一, 1872–1955) extended the institutional program.2 Ueda argued that the educated Tokyo speech of his day was fit to serve as the standard language. The working definition of "Japanese" as the language of educated, middle-class Tokyo residents traces to this position.2
A useful terminology point: 国語 and 標準語 are not interchangeable. 国語 is the national language as the ideological object of the nation-state. 標準語 is the prescribed standard variety. Lee's argument is specifically about 国語 as ideology.2
Why the 山の手 Tokyo middle class
The standard was modeled on the educated middle- and upper-class speech of Tokyo's 山の手 (yamanote, the "uptown" residential districts). It was not modeled on the working-class 下町 (shitamachi, "downtown") speech of merchants and craftsmen.3 One scholarly description calls 標準語 "the newly developed code derived from the educated middle-and-upper-class Tokyo dialect during the Meiji period."3
Tokyo functioned as the political and cultural center of the new state, which is why its prestige variety, rather than any other regional speech, was selected as the base.1 The 山の手 variety is itself just one Tokyo speech form. By the same logic that elevated it, 下町 Tokyo speech is a "dialect."31
言文一致: closing the gap between writing and speech
Genbun itchi (言文一致, "unification of the spoken and written language") was a movement from the late nineteenth into the early twentieth century. It aimed to replace classical written Japanese (文語) and 漢文 (kanbun, classical Chinese-style writing) with a vernacular (口語, kōgo) written style.5 The term 言文一致 was coined by Kanda Takahira (神田孝平) in 1885.5
From classical 文語 to a modern written standard
Futabatei Shimei (二葉亭四迷) is generally credited with the first sustained use of a vernacular narrative style, in his novel 『浮雲』(Ukigumo, "The Drifting Cloud"), published from 1887.5 Futabatei credited his colloquial model partly to the rakugo performer San'yūtei Enchō (三遊亭円朝), whose spoken performances had been transcribed by shorthand (速記, sokki). The spoken standard the novelists reached for was educated Tokyo speech.56
The contrast below shows the same idea in two written registers. This is the spoken-versus-written split the movement set out to address. The first line is the classical 文語 register that the movement set out to retire. The second is the modern 口語 register a learner reads today. Both sentences are constructed for illustration at an N3-readable level and checked against the 文語/口語 contrast in the cited account. The pair is not a quotation from 『浮雲』.

"The sun set, and the wind grew very cold." (constructed 文語 register)
日が暮れて、風がすっかり冷たくなった。5
"The sun went down, and the wind turned completely cold." (constructed 口語 register)
The movement stalled roughly between 1890 and 1895, then revived with Natsume Sōseki among the key figures. By about 1908, novels had abandoned 文語 and 漢文, with newspapers following by the 1920s.5 One register the reform produced is the plain-written である調, the sentence-final style of essays and reference prose.
古い話である。6
"It is an old story." (constructed である調 plain-written register)
Building the standard: committees and classrooms
A national ideology needs institutions. Between the Meiji-era idea of 国語 and the broadcast era, the standard was institutionalized through a state committee and the school system.
The 国語調査委員会 (1902)
The 国語調査委員会 (Kokugo Chōsa Iinkai, "National Language Research Council") was established by the state in 1902 to survey dialects and set policy for selecting and codifying a standard.43 Its work made standardization official language planning: survey regional variation, then define and spread a single standard.4 The 1902 date anchors the policy machinery between the Meiji ideology of the post-1868 years and the broadcast era that opened in 1925.43
School as the enforcement engine
From around the 1890s, schools promoted standard-language education (標準語教育) under the political and social demands of centralization and modern nation-building.7 National textbooks (国定読本, the 尋常小学読本 series) and compulsory schooling spread the standard and taught children that their home speech was incorrect.3
Ministry of Education guidance on 国語, stated in 1947 and again in 1951, directed that dialects be avoided in favor of the "correct form" (正しいことば). The intense first-half-of-the-century promotion of 標準語 carried a corresponding stigmatization of dialect.3
The classroom is where the policy reached individual children. National schooling did not merely teach a useful shared variety alongside home speech. It delivered the message that a child's home speech was wrong. Read this as enforcement, not as benign literacy work.3
NHK and the voice of the standard
Print and schooling spread the standard's grammar and vocabulary. Broadcasting added its sound.
Radio from 1925 and broadcast pronunciation
Radio broadcasting in Japan began in 1925; the first broadcast aired on 22 March 1925, and the Tokyo broadcasting station was established at Atago-yama that year.8 Because radio carried the standard into homes nationwide, announcers were expected to speak "correct" Japanese. That expectation standardized not only grammar and vocabulary but pronunciation and pitch accent.8
That demand produced a broadcast accent reference. NHK first published an accent dictionary (『日本語アクセント辞典』) in 1943. That lineage continued with the 2016 revision of 『NHK日本語発音アクセント新辞典』, which records the Tokyo-variety accent positions NHK treats as standard for its announcers and narrators.8 Postwar television extended the same broadcast standard, reinforcing the spread of the Tokyo-based norm into daily listening.3
The milestones above span the better part of a century. The timeline gathers them in order.

標準語 vs 共通語: the distinction that matters
This is the core concept of the whole topic. The authoritative definitions and the postwar shift come from the National Institute for Japanese Language and Linguistics (国立国語研究所, NINJAL) Q&A QA-138, authored by 三井はるみ.7
標準語: the prescriptive "correct" language
NINJAL defines 標準語 as「ある言語の中で、規範的な正式の言い方と見なされて、公的な場や改まった場で話したり書いたりする時に使われることばのこと」. In other words, within a given language, it is the variety regarded as the normative, official way of speaking, used when speaking or writing in public or formal settings.7
The term is value-laden and prescriptive. It carries the sense of a single correct or proper form, the ideal against which other speech is measured.7 One supporting definition, citing the 1955 国語学辞典, calls 標準語 "the ideal kokugo, constructed by refinement and control of kyōtsūgo according to a certain standard."4
共通語: the language everyone shares
NINJAL defines 共通語 as「異なる言語を話す人同士が意志を通じ合うために用いる共通の言語のこと」. In the Japanese case, NINJAL says it「方言の違いをこえて互いに通じ合うことばを指す」. That means the shared language that speakers of different varieties use to understand one another across dialect differences.7
共通語 is descriptive and carries no value judgment. It is the de facto shared variety, and it coexists with dialect rather than branding dialect as wrong.7 In NINJAL's survey wording, it is treated as「全国どこでも通じることば、東京語に近いが、必ずしも一致しない」. That is, it is a variety close to Tokyo speech but not necessarily identical to it, and sorted apart from 方言.7
The two terms answer different questions, and the table keeps them apart.
| Question | 標準語 (prescriptive) | 共通語 (descriptive) |
|---|---|---|
| What kind of statement? | Normative: the "correct/proper" form | Descriptive: the variety people actually share |
| Carries a value judgment? | Yes; other speech measured against it | No; no right-vs-wrong claim |
| Relationship to dialect | Dialect framed as deviation | Coexists with dialect |

Why the field shifted from 標準語 to 共通語 after WWII
NINJAL states the shift directly:「戦後、教育の分野では『標準語』に代わって『共通語』が目標とされるようになりました」. That is, after the war, education came to set 共通語 rather than 標準語 as the goal.7 From 昭和24年 (1949), the institute ran a survey of actual language life among residents of Shirakawa, Fukushima (福島県白河市). Based on those results, it defined 共通語 as the nationally intelligible variety, close to but not identical with Tokyo speech, and handled it as distinct from 方言.7
The term 標準語 had been in active use since the Meiji era. 共通語, paired against 方言, became widespread only after WWII through these NINJAL surveys.7 Carroll notes that 標準語 was gradually replaced by 共通語 in scholarly and educational usage to shed the unpleasant prescriptive associations of the prewar standard. In other words, the shift dropped the value judgment that branded dialects inferior.4
Moving from 標準語 to 共通語 was a deliberate choice to stop calling one variety "correct," not a cosmetic rename. 標準語 means the prescribed single right form. 共通語 means the shared variety that lives alongside dialect without judging it. Everyday speech often blurs the two, but the field separated them on purpose.74
The dark side: dialects as "deviations"
The enforcement edge of the 国語 ideology had a name and a physical object.
方言札 and the dialect-inferiority complex
The 方言札 (hōgen fuda, "dialect card") was a punishment device used in regional schools in the post-Meiji period to enforce standard speech. A child who spoke in dialect had to wear the card until catching another child speaking dialect. The day's final wearer was subject to teacher punishment.3 The practice was modeled on European precedents, notably the French Vergonha system used against regional languages.3
Enforcement was heaviest in Tōhoku, Kyūshū, and the Ryūkyū Islands, including Okinawa. These were the regions linguistically and geographically furthest from Tokyo speech.3 In Okinawa, the card was initially adopted voluntarily by students in the early twentieth century, then became compulsory as assimilation policy intensified around 1917.3
The cumulative effect was a manufactured 方言コンプレックス (dialect-inferiority complex): home speech was recoded as shameful and deficient.3 This was linguistic coercion. It was the enforcement edge of the 国語 ideology, not an unfortunate side effect of progress.23
From shame to heritage: dialect revaluation
The prescriptive frame did not hold. From the late twentieth century onward, the field and its institutions reversed the judgment.
Dialect as identity and resource
NINJAL's stance reframes dialect positively: regional varieties are a communicative and cultural resource. The institute no longer endorses suppressing dialect in favor of a single "correct" form.710 Asked whether dialect should be avoided in public settings, NINJAL rejects the old prescriptive default. It treats dialect and 共通語 as a matter of appropriate use rather than right versus wrong.10
Sociolinguistic accounts date a values shift to the late twentieth century: regional identity was reassessed, and dialect gained status and cultural appeal through popular culture and media.4 The reversal runs from "dialect as deviation" to "dialect as heritage and identity." The prescriptive 標準語 ideology has receded, while 共通語, the non-judgmental shared variety, is the operative frame.74
Good to know
"Standard Japanese" is not "real Japanese"
標準語 and 共通語 name one variety selected by policy. 方言 are full linguistic systems, not corrupted versions of the standard. Shibatani frames the standard's selection as political, not a matter of one variety being inherently better.1 NINJAL treats 共通語 and 方言 as coexisting, not as correct versus incorrect.7
When to say 標準語 vs 共通語 today
共通語 is the safer, less loaded term for "the variety everyone understands." 標準語 carries the prescriptive "one correct form" history and the value judgment NINJAL deliberately moved away from after WWII. Reach for 共通語 unless you specifically mean the normative, ideal-standard sense.74
Treating 標準語 and 共通語 as exact synonyms
If you want to say that a neutral shared variety is understood in some region, 標準語 imports an unwanted prescriptive framing. A learner who writes その地方では標準語が通じる to mean "the shared variety everyone understands works there" has smuggled in the "correct/proper" judgment. For the value-neutral sense, use 共通語.
その地方では共通語が通じる。7
"The common language is understood in that region."
NINJAL draws exactly this line and notes that everyday usage often blurs the two terms.7
国語, 標準語, and 共通語 are three different ideas
国語 is the national language as the nation-state's ideological object, which is Lee's target. 標準語 is the prescribed normative variety. 共通語 is the descriptive shared variety that coexists with dialect. Collapsing the three loses the whole history.72
山の手 vs 下町: the standard is uptown Tokyo speech
The standard derives from the educated 山の手 (uptown) Tokyo variety, not 下町 (downtown) working-class Tokyo speech, which is itself a "dialect" by the same logic. "Tokyo speech" is not monolithic. Policy standardized the prestige half.31
