I know absolutely no Japanese letters. And FWIW, I also know absolutely no Chinese/Mandarin (btw are they the same?), Korean etc.
I speak two languages — English and another language you probably haven't heard of that does not use English-looking letters (such as "a", "b" etc).
Anyway, provided I'm told that a given text is Japanese, I can tell if a letter is Kanji, Katakana, or Hiragana.
Which I think is commendable — if I may say so myself — given I didn't even know about the existence of "Kanji", "Katakana", or "Hiragana" until 3 years ago.
