From what I've seen, rather than correct you when you make mistakes, they'll just say "please let's talk in english" and go from there, and several I've run into talk about having translation programs or something. I don't know if it's due to them wanting to be polite or not liking me writing their language incorrectly. As a native spanish speaker, if someone makes a mistake I'll smile and correct them because if you don't get the mistakes corrected you're never gonna learn. At least to me, the Japanese players don't seem to be inclined towards that same courtesy. 0.o;
