Katakana for Foreign Sounds: ファ, ティ, ヴ, ウィ and Friends
The basic kana chart has no “fa,” “ti,” or “v.” So to write words like カフェ (café) and パーティー (party), Japanese builds extra katakana by adding small vowels. Here is the set you need to read modern loanwords.
Why They Exist
Japanese only has は-row sounds (ha, hi, fu, he, ho), not “fa/fi/fe/fo.” To capture foreign words more accurately, katakana combines a base kana with a small vowel: フ + small ァ = ファ (“fa”).
These appear almost only in katakana, because that's where loanwords live. Knowing the pattern lets you read brand names, menus, and tech terms at a glance.
The Combinations
ファイル, カフェ, フォーク
パーティー, ディスク
タトゥー
ウェブ, ウォーター
ヴァイオリン (also バイオリン)
シェフ, ジェット, チェック
How the Trick Works
Every one of these combinations uses the same move: take a kana whose consonant you want, strip its vowel, and write the vowel you actually need as a small character beside it. フ carries the f-sound, so フ + small ァ gives you fa. テ carries the t-sound, so テ + small ィ gives you ti.
This is the identical principle behind きゃ and しゅ in hiragana, where a small ゃゅょ merges with the kana before it. The difference is only which vowels get shrunk. Hiragana shrinks や, ゆ, よ; katakana additionally shrinks ア, イ, ウ, エ, オ. Once you see them as one system, there is very little new to memorise.
One rule falls out of this: the small vowel always wins. Whatever vowel the base kana carried is thrown away. フォ is fo, not fuo. ティ is ti, not tei.
Old Spellings vs New
Knowing ティ exists does not mean it gets used. This is what trips up students who have memorised the chart. Words borrowed before the extended kana caught on were written with ordinary kana, and those spellings stuck.
| English | Japanese | Note |
|---|---|---|
| ticket | チケット | Standard. ティケット is not used. |
| team | チーム | Standard. ティーム is not used. |
| party | パーティー | Modern spelling with ティ won out here. |
| whisky | ウイスキー | The older ウイ spelling remains standard on labels. |
| web | ウェブ | Borrowed recently, so it uses ウェ from the start. |
| violin | バイオリン | ヴァイオリン also appears, but バ is more common in print. |
No rule predicts which spelling a word takes. As a rough guide, the older and more settled the loanword, the more likely it keeps the plain kana. Treat each as vocabulary. When in doubt, copy what you see on packaging and signage.
Sounds Japanese Doesn't Have
The extended katakana solve some gaps but not all. These four are the ones that most affect how your own name and your English words come out in Japanese.
ライト covers both 'light' and 'right'. Context decides, and native speakers genuinely cannot hear the difference without training.
'Think' becomes シンク, 'the' becomes ザ. There is no closer option.
'Video' is ビデオ. See the ヴ section below.
'Bed' becomes ベッド, 'bag' becomes バッグ. Japanese syllables end in a vowel or ん, so English word-final consonants gain one.
This is why loanwords come out longer than the originals. “Strike” is one syllable in English and five mora in Japanese (ス・ト・ラ・イ・ク). When a katakana word looks unrecognisable, say it slowly with even beats. The English is usually hiding inside the rhythm.
ヴ — the Contested One
ヴ is ウ with a dakuten, invented to represent the English v. It is the only extended katakana that regularly gets replaced rather than used: most Japanese speakers write and say バイオリン rather than ヴァイオリン, and ビデオ rather than ヴィデオ.
ヴ has no distinct sound in most speakers' Japanese. Read ヴァイオリン aloud and what comes out is a バ anyway, so the extra character buys spelling complexity and no audible distinction. Japan's Ministry of Foreign Affairs reached the same conclusion: a law that took effect in April 2019 removed ヴ from official country names, so セントクリストファー・ネーヴィス became ネービス and カーボヴェルデ became カーボベルデ.
For your own study: recognise ヴ so you can read it, but write バ行 unless you are copying a specific brand or title that uses ヴ. You will never look wrong writing ビデオ.
Where Learners Slip
- Inventing spellings from the chart. Knowing ティ exists leads people to write ティケット for ticket. It is チケット, always. The chart tells you what is possible, not what is used.
- Forgetting the long vowel mark. コーヒー, パーティー, ケーキ. The ー is a full mora and dropping it changes the word's rhythm. In katakana the long vowel is always ー, never a repeated vowel kana.
- Missing the small ッ. ベッド (bed) and ベット are different words, and the small ッ is a beat of silence rather than a doubled letter. Learners who read past it end up a mora short.
Typing Them
Just type the sound: fa → ファ, ti → ティ, va → ヴァ, che → チェ. To force a small vowel alone, prefix with l or x (e.g. xa → ァ).
Teacher's Note
Pronunciation can vary — older speakers may say バイオリン where younger ones write ヴァイオリン, and ティ is sometimes simplified to チ in casual speech. Read the special katakana confidently, but don't be surprised by both forms in the wild.
