Heheh, well if everyone would like something like this I'll do a short "How-to" guide on using the link I used, once I get my laptop ready by sunday. [@LostBrotherGrimm]

You can get mobile internet for a pretty cheap fee too. BUT.
What I would is ask your landowner if there is wIfI that you can already use, temporarily, of course. They usually will have the infrastructure built in already. You might have to pay the bill but it's often no difference as when you do get your wifi, also, you might not have to pay the full bill as they will be using it too.

Getting around japan as a gaijin isn't easy without internet, the shinkansen (train lines) alone will send you to madness. Trust me, I live here.
