Convert Japanese kana into Hepburn romaji — the most common romanization for names and forms. It handles long vowels, double consonants (small tsu) and syllabic n correctly. Enter the reading in hiragana or katakana; kanji are not converted. Everything runs in your browser.
How to use
- Type or paste the reading in hiragana or katakana.
- Choose whether to capitalize each word, which suits names.
- Copy the romaji result.
How it works
Hiragana is first normalized to katakana, then each kana (and combinations like kya, sha, cho) is mapped to its Hepburn spelling. A small tsu doubles the next consonant, the long-vowel mark extends the previous vowel, and syllabic n becomes n (or n' before a vowel) to avoid ambiguity.

FAQ
- Does it convert kanji?
- No. Kanji have many possible readings, so type the reading in hiragana or katakana and it will be romanized.
- What is Hepburn romaji?
- Hepburn is the most common system for writing Japanese in Latin letters, used on most signs, passports and forms.
- How are long vowels written?
- They are spelled out, so とうきょう becomes toukyou. Passports often drop the long vowel (Tokyo); adjust by hand if your form requires that.
- Is it suitable for passports?
- It gives a Hepburn reading, but passport rules sometimes simplify long vowels. Always confirm the exact required spelling.
- Is my text sent to a server?
- No. The conversion happens entirely in your browser.
