Heh, I'm so jealous of you

Well, it would be an expensive start if you have to check into an hotel in the beginning. But you still have some time though.
So I guess you know your stuff when it comes to studying at a university in Japan, so if you don't mind I woul live to ask you some questions. There are some things I just can't find on the internet, and it's bothering me a lot.
1. How long does one semester at a japanese university last. In Norway it's from august- december or something, almost 6 months, is it the same in japan.
2. I thought that a school year in japan was starting and ending in february. Is it the same at a japanese university? I noticed that you are going to japan in september was it? So if I wan't to take my 3rd semester in japan, I could start right after summer then?
I hope I'm not bothering you : )
