Transcription into Japanese

From Wikipedia, the free encyclopedia

In contemporary Japanese writing, foreign-language loanwords and foreign names are normally written in the katakana script, which is one component of the Japanese writing system. As far as possible, sounds in the source language are matched to the nearest sounds in the Japanese language, and the result is transcribed using standard katakana characters, each of which represents one syllable (strictly mora). For example, America is written アメリカ (A-me-ri-ka). To accommodate various foreign-language sounds not present in Japanese, a system of extended katakana has also developed to augment standard katakana.

Katakana, like hiragana, has a one-to-one correspondence between sounds and characters. Therefore, once the "Japanese sound" of a word is established, there is no ambiguity in its katakana spelling (unlike spelling in English, for example).

A much less common form of transcription, Ateji, uses kanji characters for their phonetic values.

Practicalities of transcription[edit]

Word length[edit]

Because Japanese is written with relatively complex Kanji characters, Japanese text must generally be written larger for legibility. Furthermore, as both Kanji and Kana are traditionally of equal width and height, Japanese characters are generally much larger than Latin characters. As Kanji are logographic and Kana encode entire syllables (or rather, morae), the higher information density of Japanese writing usually evens out with the larger text so that Japanese and English texts take about the same amount of space, but challenges arise with foreign consonant clusters incompatible with Japanese phonotactics and the Kana system. For example, the word remote control becomes the cumbersome リモートコントロール (ri-mō-to-ko-n-to-rō-ru) in Japanese. Here, additional vowels are added between [t] and [k], between [t] and [ɾ], and after [ɾ] at the word's end, and the vowels of mo and ro have been lengthened to mimic the English pronunciation. These additional sounds not only add to the word's length when spoken, but it also severely bloats the word when written. As such, the word is typically shortened to simply リモコン (ri-mo-ko-n) in modern Japanese speech and writing.

Syllable structure[edit]

Since Japanese has few closed syllables, syllable-final consonants in the source language are often represented using the -u (or sometimes -o or -i) kanas with implicitly silent vowels – though this vowel often is pronounced in Japanese – or the syllable coda is not represented at all. For example, the name Jim is written ジム (Ji-mu). A similar principle applies to consonant clusters; for example spring would be transcribed as スプリング (su-pu-ri-n-gu), and scratch would be transcribed as スクラッチ (su-ku-ra-cchi).


Japanese has only five native vowel sounds, each a pure vowel (monophthong) with a long and short form, and some degree of approximation is necessary when representing vowels from, for example, English. Diphthongs are represented by sequences of vowels, and pronounced with hiatus, as a sequence of discrete monophthongs, not a diphthong, as in ブラウン Bu-ra-u-n "Brown", ナイス na-i-su "nice", ディア di-a "dear/deer", レア re-a "rare". etc. The English spelling <ore> (phonologically /ɔː/ (RP) or /ɔːr/ (GA)) is usually "diphthongized" as o-a in Japanese (e.g. コア ko-a "core"), possibly because it is also pronounced as a diphthong (/oə/) in some accents of English. The English /eɪ/ is transcribed to either e-e (エース e-e-su "ace") or e-i (スペイン Su-pe-i-n "Spain"); similarly, /əʊ/ is transcribed to either o-o (ショー sho-o "show") or o-u (シャドウ sha-do-u "shadow").


Japanese does not have separate l and r sounds, and l- is normally transcribed using the kana that are perceived as representing r-. For example, London becomes ロンドン (Ro-n-do-n). Other sounds not present in Japanese may be converted to the nearest Japanese equivalent; for example, the name Smith is written スミス (Su-mi-su). Foreign sounds can be difficult to express in Japanese, resulting in spellings such as フルシチョフ Furushichofu (Khrushchev), アリー・ハーメネイー Arī Hāmeneī (Ali Khamenei) and イツハク・パールマン Itsuhaku Pāruman or イツァーク・パールマン Itsāku Pāruman (Itzhak Perlman).

The English voiceless labialized velar approximant /hw/ (orthographically wh), which is a distinct phoneme from /w/ in some varieties of English, can be transcribed as ho(w)-. For example, White is ホワイト Howaito, whale is ホエール hoēru.

French /w/ is typically transcribed as u, but the sequence /wa/ is as o-(w)a (e.g. ポアロ Po-a-ro "Poirot").

The English /ti(ː)/ and /tɪ/ is typically transcribed to チ chi (e.g. チーム chīmu "team"), but ティ ti is also used (ティア tia "tear"). The suffix -tic can be transcribed to either チック -chikku or ティック -tikku. However, -ty is almost always transcribed to ティ(ー) -ti(i), not *チ(ー) *-chi(i) (e.g. パーティー pātī "party", インフィニティ infiniti "infinity").

The English schwa /ə/ is variously "transcribed" to a, e, o, depending on the English spelling (this is more of transliteration than it is transcription). For example, デュアル dyu-a-ru "dual", デュエル dyu-e-ru "duel", テスタメント Te-su-ta-me-n-to "Testament", ロンドン Ro-n-do-n "London". There are no definite rules when it comes to the schwa, however; e.g. ランダム ra-n-da-mu "random", オープン o-o-pu-n "open", ザ za "the". The British /ə/ which is equivalent to the North American /ɚ/ is transcribed to a(-a); e.g. コンピュータ(ー) ko-n-pyu-u-ta(-a) "computer", モーター mo-o-ta-a "motor". On the other hand, the French schwa is transcribed to u or o (e.g. ソムリエ so-mu-ri-e "sommelier", ド do "de") similarly to instances where there's a lack of vowels, and the German schwa is almost always transcribed to e (e.g. アルベルト A-ru-be-ru-to "Albert", ウンディーネ un-di-i-ne "undine").

Although the diphthong /au/ across languages is usually transcribed as アウ a-u, local reading transcriptions of the same sequence from Mandarin, represented in both Wade–Giles and Pinyin as ao are represented as アオ a-o instead, again in more of a manner of transliteration based on these systems - e.g. マオ・ツォートン ma-o tso-o-to-n (Mao Zedong).

The English /æ/ is typically transcribed to a; e.g. マン ma-n "man", チャネル cha-ne-ru "channel". The sequences /kæ/ and /ɡæ/ are sometimes transcribed to kya and gya respectively; e.g. キャンディ kyandi "candy", ギャラクシー gya-ra-ku-shi-i "galaxy".

The older English suffix -age /-ɪdʒ/ is always transcribed to -e-e-ji as if it were pronounced as /eɪdʒ/ as in "age" or "rage"; e.g. メッセージ me-s-se-e-ji "message", パッケージ pa-k-ke-e-ji "package". The more recent -age /-ɑːʒ/ is more "properly" transcribed to -a-a-ju; e.g. ミラージュ mi-ra-a-ju "mirage". However, "garage" /gəˈrɑːʒ/ is more commonly transcribed to ガレージ ga-re-e-ji as it also has /ˈgærɪdʒ/ as an alternative pronunciation in British English.

The phoneme /v/ in various languages is transcribed either to b or v, although it is unknown whether there is such an equivalent phoneme /v/ in Japanese. For example, ベネチア Benechia / ヴェネツィア Ve-ne-tsi-a "Venezia" (Italian for "Venice"), オーバー o-o-ba-a "over", ラブ ra-bu / ラヴ ravu "love".

The German /v/ (orthographically w) can be transcribed in several ways. In long-established words, it is generally w. E.g.: Walküre "valkyrie" > ワルキューレ wa-ru-kyu-u-re. In newer transcriptions, it can also be v. E.g.: Schwestern "sisters" > シュヴェスタン shu-ve-su-tan.

Wa is usually written as ワ, although ウァ is sometimes used in transcriptions from Ancient Greek or Latin (e.g. ミネルウァ Mi-ne-ru-wa "Minerva").

French vowels are usually phonemically transcribed, but non-phonemic stressed vowels (utterance-final) are sometimes also transcribed as long vowels. Compare the examples of メゾン me-zo-n "maison" and カレー ka-re-e "Calais", in which the same vowel /ɛ/ is transcribed as e and e-e depending on whether it is stressed or not. The French schwa is ignored altogether: words are usually transcribed as if there were no schwa at all. For example, the word "le" is transcribed as ル ru, as is the single sound /l/ in "cheval" > シュヴァル shuvaru.

Although a syllable-final /n/ is typically transcribed using the moraic ン n, ン is used in French to transcribe nasalized vowels, so French words with a final /n/ often use ヌ nu instead for distinction, e.g. マドレーヌ Ma-do-re-e-nu "Madeleine". This is especially the case when the masculine and feminine of a word are distinct in French, e.g. bon --> ボン bo-n, vs. bonne --> ボンヌ bo-n-nu (the n is sometimes doubled, especially when the French orthography uses two n, even if it has no consequence in the French pronunciation).

Plain short consonants may be transcribed as geminated consonants to reflect the laxness of the preceding vowel, although this is not universal and there are plenty of exceptions. For example: English kick is キック ki-k-ku and castle is キャッスル kya-s-su-ru, but extra is エクストラ e-ku-su-to-ra and battle is バトル ba-to-ru. This practice expands to almost all English obstruents regardless of their voicing (/k/, /ɡ/, /s/, /z/, /f/, etc.), also to German/Scots /x/, occasionally to /n/ and /m/ (as pseudo-geminated consonant sequences /nn/ or /nm/). For example: English bag is バ(ッ)グ ba-(g)-gu; English Anna is アンナ A-n-na; English gamma is ガンマ ga-n-ma; English shuffle is シャッフル sha-f-fu-ru; German Mach is マッハ ma-h-ha, Masoch is マゾッホ Ma-zo-h-ho.

German [x] is transcribed roughly as h-h, accordingly to its preceding vowel, if it's not followed by a vowel (e.g. マッハ ma-h-ha "Mach", バッハ Ba-h-ha "Bach", マゾッホ Ma-zo-h-ho "Masoch"); [ç], its allophone occurring only after high vowels and consonants, are as h if followed by a vowel (e.g. メルヘン me-ru-hen "Märchen"), or as hi if not (e.g. リヒター Ri-hi-ta-a "Richter"). Russian /x/ is transcribed as fu if not followed by a vowel (e.g. カザフスタン Ka-za-fu-su-ta-n "Kazakhstan"). Mandarin [ɕ] (in pinyin x(i)) is transcribed as sh (e.g. シャオ shao from 小 xiǎo "little").

Geminated consonants are typically transcribed consistently and faithfully, as gemination is also featured in Japanese. The only notable exceptions are /rr/ and /ɲɲ/, although /ll/ and /ʎʎ/ are still transcribed. Examples: Arabic: الله, romanizedAllāh is アッラーフ A-r-ra-a-fu; Italian Donatello is ドナテッロ Do-na-te-r-ro; Italian degli is デッリ de-r-ri; but Italian Verrocchio is simply ヴェロッキオ Ve-ro-k-ki-o, not *Ve-r-ro-k-ki-o. Italian /ɲɲ/ may be transcribed as the lengthened portion of the preceding vowel and a sequence of /nj/. For example, Sardegna is サルデーニャ Sa-ru-de-e-nya.

Similar to the way speakers of English say Italian words, Japanese does not usually transcribe the Italian glide /j/ to reflect its true nature, but as /i/, perhaps for consistency and convenience. For example, Venezia is ヴェネツィア Ve-ne-tsi-a, Sicilia is シチリア Shi-chi-ri-a. Contemporary transcriptions of palatalized consonants from Slavic languages, however, are made using yōon, e.g.: Russian ピャチゴルスク Pya-chi-go-ru-su-ku (Pyatigorsk), Polish ビェルスコ=ビャワ Bye-ru-su-ko=bya-wa (Bielsko-Biała).

Modern English compounds are usually transcribed in a way that reflects the independent pronunciations of the individual components. That is to say, there is no phonetic linking between components. For example, "overall" is transcribed as オーバーオール o-o-ba-a-o-o-ru, not *o-o-ba-a-ro-o-ru as it is pronounced in English. However, there are a few exceptions, such as "pineapple", which is transcribed as パイナップル pa-i-na-p-pu-ru, or "double-u", as ダブリュー da-bu-ryu-u.

Long vowels[edit]

Long vowels are generally written with ー to indicate lengthening, as in コーラ kōra (cola), rather than writing a distinct vowel ×コウラ *koura. There are two irregularities of note here. Firstly, lengthening of the final vowel may be ambiguous, and vary over time or between users. For example, in present Japan, "computer" is generally represented as コンピューター konpyūtā (long final), but in some cases, such as the computer industry, following Japanese Industrial Standards, it is represented as コンピュータ konpyūta (short final).[1] Secondly, in modern Chinese loanwords, notably food names, in careful transcription diphthongs are represented by separate vowels, even if in Japanese they would appear to be a long vowel; this is particularly common with òu, especially in 豆 dòu "(soy) bean", usually rendered as トウ. Further, long vowels in the Japanese transcription need not reflect Chinese pronunciation. For example, the dish 東坡肉 "Dongpo pork", in pinyin dōngpōròu (dōng·pō·ròu), is represented in Japanese as ドンポーロウ donpōrou, or more commonly トンポーロウ tonpōrou. Note that in Chinese pinyin ō represents a high tone, while in Japanese ō represents a long vowel, and /d/ is pronounced differently (Chinese /d/ is similar to Japanese or English /t/). This distinction is not always followed, and varies by term: the spelling トンポーロー tonpōrō is also common; and in terms such as 回鍋肉 twice cooked pork, the spelling ホイコーロー is more common, despite representing diphthongs.

Extended katakana[edit]

In modern times, an extended katakana system has developed to cater for foreign sounds not present in Japanese. Most of these novel katakana forms are digraphs, composed of standard katakana characters, but in digraph combinations not found in native words. For example, the word photo is transcribed as フォト (fo-to), where the novel digraph フォ (fo) is made up from フ (normally fu) plus a novel small combining form of オ (normally o). In other cases novel diacritics may be applied to create new sounds, such as ヴ for vu, which consists of ウ (u) combined with a dakuten to indicate a voiced pronunciation.


Japanese is written without spaces between words, and, to aid understanding, foreign phrases and names are sometimes transliterated with an interpunct separating the words, called a nakaguro (中黒, middle dot); for example, ビル・ゲイツ (Bill Gates). When it is assumed that the reader knows the separate gairaigo words in the phrase, the middle dot is omitted, especially for wasei eigo. For example, the phrase コンピューターゲーム konpyūtā gēmu ("computer game") contains two well-known gairaigo, and therefore is not written with a middle dot; the same principle is applied for パンティストッキング panti sutokkingu ("pantyhose", lit. "panty stocking"), Japanese coinage.

Katakana tables[edit]

The following tables give the Hepburn romanization and an approximate IPA transcription for katakana as used in contemporary Japanese. Their use in transcription is, of course, in the inverse direction.

Standard katakana[edit]


  1. ^ Prior to the e/ye merger in the mid-Heian period, a different character (𛀀) was used in position e.
  2. ^ a b Theoretical combinations yi and wu are  unused . Some katakana were invented for them by linguists in the Edo and Meiji periods in order to fill out the table, but they were never actually used in normal writing.
  3. ^ The combination ye existed prior to the mid-Heian period and was represented in very early katakana, but has been  extinct  for over a thousand years, having merged with e in the 10th century. The ye katakana () was adopted for e (displacing 𛀀, the character originally used for e); the alternate katakana 𛄡 was invented for ye in the Meiji period for use in representations of Old and Early Classical Japanese so as to avoid confusion with the modern use of for e.
  4. ^ a b c The characters in positions wi and we are  obsolete  in modern Japanese, and have been replaced by (i) and (e). The character wo, in practice normally pronounced o, is preserved in only one use: as a particle. This is normally written in hiragana (を), so katakana sees only limited use. See Gojūon and the articles on each character for details.
  5. ^ a b c d e The (di) and (du) kana (often romanised as ji and zu) are primarily used for  etymologic spelling , when the unvoiced equivalents (ti) and (tu) (usually romanised as chi and tsu) undergo a sound change (rendaku) and become voiced when they occur in the middle of a compound word. In other cases, the identically-pronounced (ji) and (zu) are used instead. (di) and (du) can never begin a word, and they are not common in katakana, since the concept of rendaku does not apply to transcribed foreign words, one of the major uses of katakana.

Extended katakana[edit]

The following katakana tokushuon (特殊音)[2] have been developed or proposed specifically for the purposes of transcribing foreign words. Examples such as トゥ(tu) in カートゥーン(cartoon), ティ(ti) in パーティ(party), ツァ (tsa) in モーツァルト(Mozart) are found mostly in foreign words.

 Orange  General kana combinations used for loanwords or foreign place names or personal names, set forth by the Japanese government's Ministry of Education, Culture, Sports, Science and Technology (MEXT, Monbushō).[3]
 *Blue  Combinations used for more accurate transliteration of foreign sounds, again set forth by MEXT.[clarification needed]
 †Beige  Suggestions by the American National Standards Institute (ANSI Z39.11)[4] and the British Standards Institution (BS 4812),[5] both are identical and from 1972.[clarification needed] Attention: In these old standards obsolete kanas like ヰ(wi) and ヱ(we) are still included, same for ヷ(va), ヸ(vi), ヹ(ve), ヺ(vo).
 ‡Purple  Combinations that appear in the 1974 version of the Hyōjun-shiki formatting.[6]
