Write Your Name in Japanese Katakana: A Teacher’s Step-by-Step Guide

Type your name into one of the dozens of “Japanese name converter” sites and you’ll get an answer in half a second. Sometimes it’s right. Often it’s slightly wrong in a way that will follow your child around every classroom, form and self-introduction they ever do in Japanese. A name is the first thing you write and the first thing you say, so it’s worth getting properly right. I’m a Japanese teacher, and this guide shows you how to write your name in Japanese katakana using the same rules I use when I correct a new student’s on the first day.

Can-you-use-it legend: ◎ = standard and safe · △ = acceptable, with caveats · ✗ = avoid.

Why foreign names use katakana

Japanese has three scripts, and they divide the work. Hiragana handles native Japanese words and grammar. Kanji handles meaning-carrying words. Katakana handles foreign words, loanwords, sound effects — and foreign names. So Emma is エマ, not a hiragana or kanji version. This isn’t a rule you can opt out of stylishly: writing a foreign name in hiragana looks like a mistake, and using kanji is a separate thing entirely (more on that below).

Teacher’s note — you’re not spelling, you’re transcribing sound: This is the mental switch that fixes most errors. Katakana doesn’t record your name’s letters; it records your name’s sound, using the syllables Japanese has. So the silent letters vanish, doubled letters collapse, and anything Japanese can’t pronounce gets replaced by its nearest neighbour. Say your name out loud, slowly, and transcribe what you hear — never what you’d type.

The four rules that decide your name

Rule	What happens	Example	Katakana
Every consonant needs a vowel	Lone consonants gain a “u” or “o”	David → Da-vi-d(o)	デイビッド
No L sound	L becomes the R-row	Lily → Ri-ri-	リリー
Long vowels use ー	A held vowel gets a dash	Lee → Ri-	リー
Double consonants use っ	A small tsu marks the pause	Beckham → Be-k-ka-mu	ベッカム
No “th”, “v” softens	th → s/z, v → b (often)	Matthew → Ma-shu-	マシュー
Middle dot separates names	・ between given and family name	Emma Smith	エマ・スミス

Common names, done properly

Name	Katakana	Rōmaji	What tripped it up
Emma	エマ	Ema	Double m collapses — not エンマ
Oliver	オリバー	Oribā	L→R, v→b, long final vowel
Sophia	ソフィア	Sofia	ph→f, small ィ makes “fi”
Liam	リアム	Riamu	Final m needs a vowel: ム
Charlotte	シャーロット	Shārotto	Silent final e drops; っ for the tt
Noah	ノア	Noa	Silent h disappears
Isabella	イザベラ	Izabera	s→z by sound, ll→single r
Ethan	イーサン	Īsan	th→s; long first vowel
Ravi	ラビ	Rabi	v→b
Mei	メイ	Mei	Already fits Japanese sounds
Lucas	ルーカス	Rūkasu	L→R, long ū, final s→ス
Grace	グレース	Gurēsu	Gr needs a vowel: グ

Teacher’s note — where the converters go wrong: Automatic tools work from spelling, so they miss the two things that matter most. First, silent letters: Charlotte ends in a silent e, and a tool that transcribes letters gives you シャーロッテ, which sounds like a different name. Second, long vowels: whether you are リサ or リーサ depends on how you say it, and no software can hear you. That’s why I always ask a new student to say their name aloud twice before I write anything.

What about writing my name in kanji?

This is the most-asked follow-up, and the honest answer has two halves. Katakana is your real name in Japanese — it’s what goes on official forms, school registers and your self-introduction. A kanji version is a fun, unofficial nickname called ateji (当て字), where characters are chosen for sound or meaning rather than accuracy.

Ateji is genuinely enjoyable, and children love it. But choose the characters with someone who reads Japanese. Kanji picked purely by sound can land on meanings you very much didn’t intend — the classic disaster is a set of characters that sounds right and means something like “dark demon lord.” Pick for good meaning first, sound second, and always have a native speaker sanity-check it before it goes on a t-shirt.

Japanese	Rōmaji	English	Use it?
はじめまして。	Hajimemashite.	Nice to meet you.	◎ Always first
エマです。	Ema desu.	I’m Emma.	◎ No honorific on yourself
オーストラリアから来ました。	Ōsutoraria kara kimashita.	I came from Australia.	◎ Swap in your country
十歳です。	Jussai desu.	I’m ten years old.	◎ Kids’ self-intro staple
よろしくお願いします。	Yoroshiku onegaishimasu.	Please treat me well / thanks in advance.	◎ Closes every introduction

That five-line sequence is a complete Japanese self-introduction, and it’s usually the first thing a child performs in front of real classmates. Getting the name right at the top of it matters more than any other single word they’ll learn this year. For how the -san at the end of other people’s names works, see our guide to Japanese honorifics.

A small exercise that works

Have your child write their own name large, then the names of three people they love, then their favourite food. That’s the katakana chart’s most useful corner learned in ten minutes, with maximum motivation — because it’s their name. Then, crucially, have them say it out loud to someone who can tell them whether it sounds right.

That last step is the one a converter site can never do. A name is a sound before it’s a spelling, and the only way to know yours is correct is to say it to a Japanese speaker and watch them recognise it instantly.

Frequently asked questions

How do I write my name in Japanese?

Use katakana, and transcribe the sound of your name rather than its spelling. Break it into Japanese syllables, replace L with the R-row, add vowels after lone consonants, mark long vowels with ー and doubled consonants with っ. Separate given and family names with a middle dot: エマ・スミス.

Why is my name written in katakana and not hiragana?

Katakana is the script Japanese reserves for foreign words and names. Writing a foreign name in hiragana reads as an error to Japanese speakers, in the same way lowercase-only writing looks off in English.

Are online Japanese name converters accurate?

Often close, but not reliable. They work from spelling, so they mishandle silent letters (Charlotte → シャーロッテ instead of シャーロット) and can’t judge vowel length, which depends on how you actually pronounce your name. Have a Japanese speaker confirm it.

Can I write my name in kanji instead?

You can create an ateji (当て字) version for fun, choosing kanji by sound or meaning — but katakana remains your official name in Japanese. Always have a native speaker check kanji choices, because characters picked by sound alone can carry unintended meanings.

Where can my child learn to write and say their name properly?

At TOMODACHI JAPAN, qualified Japanese teachers help children get their own name right from day one, then use it in real self-introductions with peers living in Japan. See our plans and pricing, or our katakana practice guide using Pokémon.
