Questions
How do I convert romaji to katakana?
Type romaji in the box, for example koohii, and the katakana appears as you type: コーヒー. Tap Copy to paste it anywhere. It is free and works on your phone.
How do I type a long vowel in katakana?
Type the vowel twice (koohii → コーヒー, suupaa → スーパー) or type a dash (ko-hi- → コーヒー). Both give the long vowel mark ー.
How do I type sounds like ティ, ファ or ヴァ?
Type thi for ティ, dhi for ディ, fa for ファ, she for シェ, je for ジェ and va for ヴァ. These sounds only appear in loanwords, so they are written in katakana.
When is katakana used instead of hiragana?
Katakana is for words from other languages (コーヒー, coffee), foreign names, and sound effects. Hiragana is for Japanese words and grammar. Tap Hiragana above the box to switch.
Can I write my name in katakana?
Yes. Foreign names are written in katakana by how they sound, not how they are spelled. Our Name in Japanese tool shows the usual spellings of common names and makes a card you can share.
