FAQ
Hepburn vs Kunrei — what is the difference?
Hepburn follows English pronunciation (shi, chi, tsu) and is used on passports and road signs. Kunrei follows Japanese phonology (si, ti, tu). This tool uses Hepburn.
Can I use this spelling on a passport?
Hepburn is the standard, but personal names can have approved exceptions (for example matching a previous passport). Always follow the passport office's rules.
Is long 'ou' written ou or o?
Passport style shortens it to o (Sato, Ota). You can also choose the literal 'ou' spelling in this tool.
Can it convert kanji?
Kanji readings cannot be determined automatically — please enter hiragana or katakana.
