A few things Now I know very little about Japanese so if I m wrong just say so That aside 1 I ve heard the romaji of katakana called Katakana English many times but no reference to this term is made 2 In the Alphabet letter names in Japanese section I believe the letter Z is zetto not zeddo 3 Long vowels don t necessarily need the line over top I ve seen many romaji words with long vowels without the symbol and some long vowels are translated at a double vowel which can be awkward when there is a long o sound Some mention of these other styles of translation should be made For example student can be written as kyoshuusei kyoushuusei ky shuusei and I ve seen rarely kyooshuusei 4 Romaji is often mistakenly writen pronounced romanji There should be a note of this in the article to alleviate confusion
