Moving to Japan Help?!?

I'm 16 and since I was little dreamed about moving to Tokyo and hope to fulfill that dream. Me and my friend want to move to Tokyo after we graduate in 2 years. Before we move we want to find a decent job there and move into an apartment. After we get settled in for a year or two we're going to go to college there. I need enlightenment on this. We're learning Japanese through rosetta stone so in 2 years we'll learn a good amount of Japanese to get us by.
