Grah, right. Err, subject before the verb, yeah? So it's "I japanese am", or watashi japanese desu? Though, I'm sure desu doesn't literally mean "am" or "to be". I'm guessing "wa" is "to be". Key word guess :P Graah, confuse.
Speaking of des, does desuka indicate a question? Lol wtf, teach me japanese OTC =\
