Getting back to the topic, I've found that at least in my area, Japanese are extremely lenient when it comes to drinking. I personally don't drink myself, but I've walked into to bars and nomikai places and noone has ever asked a question. I was basically told by a university person that they're relaxed with alcohol but extremely kick-you-out-of-the-country strict with stuff like Marajuana.

Hope it helps. Try not to get carried away though.
