Well, if that's the case it's gonna be a bit difficult for us to relate to you everything that goes on in the life of a typical Japanese person. Plus, I'm not Japanese - and I may have been an exchange student for half a year but I don't think I really lived the life of a Japanese student.
Some things you CAN do, as an alternative:
1) Travel to Japan and stay there for a year
2) Correspond with a Japanese friend or e-pal (go to JapanGuide to find one)
3) Read lots and lots of manga - the non-fantasy ones, at least, to get a realistic view of the Japanese lifestyle
Or you could tell us what, in particular, you would like to know. Where lifestyles are concerned, I wouldn't know where to start.
