I side with the previous posters when they say just don`t do it to begin with.

If you`re worried about the possible penalties, etc, the easiest way to avoid them is to just not drink during that time. You have the chance to go to Japan to study... But are willing to risk that for a couple drinks? Sounds like you have priority issues.

Oh, and by the way - they won`t deport you. You`ll just likely be booted from your university program. They don`t like to have international students who break the law. But in the end, it amounts to the same thing - if you`re not attending university, you lose your visa and can no longer stay in the country.

Just wait until you`re legal. It won`t kill you.
