Romaji (Hepburn)

You have a name, a track title or an address written in kana and you need the sound in Latin letters, whether to search for it, type it into a form or say it out loud. Paste hiragana or katakana into the top box and the romaji appears below as you type: さくら becomes sakura, にほん becomes nihon, がっこう becomes gakkou. Copy and clear buttons sit right under the output.

Under the hood this is a syllable table, not a dictionary, and that carries three consequences worth stating plainly. Kanji passes through untouched, so 東京 stays 東京 in the output. The katakana long-vowel mark is never converted, so コーヒー comes out as koーhiー. And particles are transcribed by spelling rather than pronunciation: こんにちは becomes konnichiha and を becomes wo, where proper Hepburn writes konnichiwa and o.

It does its best work on plain kana: furigana, katakana names, vocabulary lists. Before pasting anything into an official form, check how that form handles long vowels, since conventions differ (macron, doubled vowel, or nothing at all) and here ありがとう comes out as arigatou. Modern combinations outside the classic table come back mixed with kana, as in ファミリー turning into fuァmiriー. Conversion happens entirely in your browser.
