Japanese to romaji haqida

Passport applications, airline bookings, visa forms and English-only websites all ask for a Japanese name in Latin letters, and each expects the same spelling every time. This converter turns hiragana and katakana into romaji as you type, and reads kanji with an open-source Japanese dictionary when you ask it to.

Passport mode follows the Hepburn rules that Japan's passport offices publish: capital letters, ん written M before B, M and P (SHIMBASHI, NAMBA), っ doubling the next consonant with T before CH (HATTORI, HATCHO), and long vowels left out (おおの ONO, さとう SATO, ゆうこ YUKO), except a name-final おお as in よこお YOKOO. It counts the 37 characters a passport has room for, and writes a long O as OH if you have asked the passport office for that spelling. Hepburn mode adds macrons and apostrophes (Tōkyō, kōhī, kin'en); Kunrei-shiki gives the school spelling (Tôkyô, Huzisan).

Kanji have many readings, and names more than most: 菅野 can be Kanno or Sugano. Once the dictionary has read your text, each kanji word is listed with its reading, the other readings it knows and a box for typing the right one. When two vowels only look like a long vowel because they belong to different kanji, as in 井上 INOUE or 松浦 MATSUURA, both letters are kept, and you can mark any other pair yourself.

The tool cannot know the reading registered for your name, so check it against your family register or an earlier passport before you submit anything.

Maxfiylik

Kana are converted by the page itself, and kanji by a copy of the kuromoji dictionary running in a background worker on your device, so your text is never sent anywhere. The only download is the 17.8 MB dictionary from the jsDelivr CDN, which your browser keeps in its cache until you remove it. Your text, settings and corrected readings are saved in this browser's local storage.

Japanese to romaji: koʻp beriladigan savollar

How do I write my Japanese name for a passport?
Type it in kana, or in kanji and let the dictionary read it, choose Passport and check the reading. Passport spelling uses capitals, writes ん as M before B, M or P, doubles the consonant for っ and leaves long vowels out, so 大野 is ONO and 佐藤 is SATO. A name already on an earlier passport has to be spelled the same way again.
Why does passport romaji drop the U in Sato or Yuko?
Japanese passports use Hepburn as the Ministry of Foreign Affairs applies it, which does not mark long vowels: おう and おお become O, and うう becomes U. A final おお stays OO, as in YOKOO. Spellings such as SATOH or OHNO are allowed only when you ask the passport office for them, and you then keep that spelling on every later passport.
What is the difference between Hepburn and Kunrei-shiki?
Hepburn writes the sounds the way English readers expect them: shi, chi, tsu, fu and ji. Kunrei-shiki, taught in Japanese schools since 1954, follows the rows of the kana table instead: si, ti, tu, hu and zi. Hepburn marks a long vowel with a macron (ō), Kunrei-shiki with a circumflex (ô). Station signs, passports and most English texts use Hepburn.
Why is the reading of my name wrong?
Kanji in names can be read in many ways, and the dictionary picks the most common reading of the word, not the one in your family register, so 菅野 may come out as Kanno when yours is Sugano. Tap another reading under the word or type the right one, and the romaji updates straight away. Your corrections stay saved in this browser.
Do I need to download anything?
Not for kana: hiragana and katakana convert instantly with nothing downloaded. Reading kanji needs the kuromoji dictionary, a one-time 17.8 MB download that your browser then keeps, so later visits start at once and work offline. A button under the text removes the saved dictionary whenever you want the space back.
