Any one know any good websites for learning Romaji japanese?

Answer 1

what you want doesn't really exist. Go read a book in the library on Japanese Romaji. and it's not Romaji japanese.

Online it's only Kana, or Kanji, but next to nothing for Romaji.

I noticed a website from an answer given as a response to your question, but since it's in the UK, there might be errors, because you know it might or might be by Japanese people, which is more authentic.

Or get a Japanese friend.
