Romaji is Japanese written in Roman letters. It's useful for beginners, but you'll want to graduate to reading hiragana directly as soon as possible.
This guide covers the complete romaji-to-hiragana mapping so you can make that transition.
The Basic Pattern
Japanese syllables follow a simple consonant + vowel structure. Each combination maps to one hiragana:
Consonant (k, s, t, n...) + Vowel (a, i, u, e, o) = Hiragana
Exception: The standalone consonant "n" (ん).

Special Cases
Double Consonants (っ)
Doubled consonant letters create small っ:
| Romaji | Hiragana | Example |
|---|---|---|
| kk | っk | sakka → さっか |
| ss | っs | zasshi → ざっし |
| tt | っt | kitte → きって |
| pp | っp | nippon → にっぽん |
Long Vowels
Extend the vowel:
| Romaji | Hiragana |
|---|---|
| aa | ああ |
| ii | いい |
| uu | うう |
| ee | ええ or えい |
| oo | おお or おう |
Note: Long "o" is usually おう (ou), not おお.
The "n" Before Vowels
Before vowels or y, use nn or n':
| Romaji | Hiragana |
|---|---|
| kan'i | かんい |
| shin'you | しんよう |
| konna | こんな |
Without the marker, it becomes a different reading:
- kani = かに (crab)
- kan'i = かんい (simple)
Romaji Systems
Different systems romanize Japanese differently:
Common Variations
| Sound | Hepburn | Nihon-shiki | Kunrei-shiki |
|---|---|---|---|
| し | shi | si | si |
| ち | chi | ti | ti |
| つ | tsu | tu | tu |
| ふ | fu | hu | hu |
| じ | ji | zi | zi |
Most learning materials and IMEs accept all variants.
Why Move Beyond Romaji
Problems with Romaji
- Ambiguity: Multiple ways to write the same sound
- Not authentic: Japanese isn't written this way
- Slower reading: Extra mental conversion step
- Missed nuances: Word boundaries unclear
- Bad habits: Pronunciation affected by English reading
The Solution
Learn to read hiragana directly. It takes about 2 weeks of focused practice. After that:
- Reading becomes faster
- Pronunciation improves
- Real Japanese text becomes accessible
- You can use proper learning materials

Quick Reference Card
Basic Pattern: consonant + vowel = hiragana
Exceptions to remember:
- shi (not si), chi (not ti), tsu (not tu), fu (not hu)
- ji for じ (not zi usually)
- n before vowels needs nn or n'
- Double consonants make っ
- Small ya/yu/yo after i-column kana
When in doubt: Try it in a Japanese IME - it will show you what works.
