Mrjones, your professor is right and you shouldn't judge a people without understanding their culture first!

He also says that Japanese people also do these same judgements, becouse they lack in experience communicating with foreign people. In my opinoin this is not complitely justified to be true, becouse languge which was used was Japanese. They would know, what they are speaking about.
After you have been in Japan a while and gain a firm grasp of the language and culture you will come to understand that the Japanese people you refer to asking, "When are you going home", is nothing more than their attempt at starting a conversation with you, nothing more, nothing less even if they are speaking Japanese to you. After all 99% of the foreigners do end up going home after their exchange program is up. They just want to get an idea how long you will be in Japan.
To "read" anything else into it like, "They must want me to leave" is just downright silly and unwarranted. After you slowly begin to understand Japanese and the culture you will discover that the Japanese are by nature shy, especially boys your age and the questions you find so offensive is just their way of starting a conversation and getting to know you better.
Get to know some of them and befriend them and you will have friends for life. I'm sure they'd like to get to know you better, but do not have the social skills on going about it and feel intimidated by you as they do many a foreigner. They do not have the social skills those in the west have.
Lighten up a bit and I'm sure your stay will be that more enjoyable.
So basicaly this would mean, that in my own native language, I could do the samethings, and people would blame it on lack in experience ? Rather than I would be doing anything wrong.
You cannot compare the two cultures as they are completely different, like night and day. It is unfair to compare them as, in your culture, you may never dream of asking them similar questions, whereas in Japanese culture it is perfectably acceptable.
You need to understand this if you are to gain anything from your exchange program. To say that they have no manners at all and must want you to go home shows that you have learned nothing of the Japanese way of thinking and culture from your stay and, if you continue along this line of thinking, you will learn nothing and will end up bad mouthing the Japanese on forums like this in the future. That will be very sad indeed.
