i have full confidence you could do it MMM, from what i've seen with international students studying masters in english here in Australia and their level of English, as well as some Koreans and Chinese and a Thai i know studying masters in Japanese in Japan, it is definitely manageable.

i do notice that most students record the lectures to go through them more slowly at home later and they often work in groups of people to help then understand difficult concepts that they had trouble understanding. of course this also depends on what you are studying, there are obviously going to be some masters that are more difficult than others.

EDIT: one more point, from attending some science lectures in Japanese with a friend while at uni, admittedly this was bachelor level, but the lecturer simply wrote 80% of what was said on the board, to compliment the hand out sheet he gave the students. Pretty much as long as you took down all the notes that was the benefit of attending the lecture.

but yeah it will change from place to place obviously.
