I don't think the romaji is there as a furigana to the kanji, it's really just here for international friendliness...

If you put romaji on a form where it asks for the furigana of your name you'd get laughed at.
(if it's written フリガナ then you write your name in katakana, if ふりがな then in hiragana, I have never ever seen it written in English)
