I'm pretty sure that if you want to take a post graduate program in Japan you will need to take it in Japanese. If you really want to take your post graduate in Japan you will likely want/need to take a few classes on learning business level Japanese, if you haven't already. I would guess you probably would want at least JLPT level 2 if not level 1 to attend school there.
You state you are moving there. How? Do you have a VISA? If you want to get a student VISA I think, though I could be wrong, that you need to be enrolled in a school first.
If you read through the forums here and other places like the GaijinPot forums you can find a lot of information about schools and jobs in Japan. IT can be fairly difficult from what I have read in the past and since the economy isn't very good at the moment I would think it might be even more difficult then usual. Don't expect to come out of a post graduate course and settle right into a high paying IT job.
One last thing, and I really don't mean to be picky, but it makes it easier to read posts if you use proper sentence structure, punctuation, and capital letters.
Hope this info helps you a bit.
