If you are marrying your roommate, you need to look into actual procedures.

It doesn't happen over night and it may take longer than you are expecting to receive a spouse visa.

And I'm assuming that your roommate is a student right now?

Someone without a job or work experience marrying a foreigner may alert the government so it could slow the process down.

Anyways, the best way for your music career is to look for someone who works in Japan as a musician coming from overseas.

They might be able to hook you up.

Final note, I don't know which city you are heading to, but some people do end up appreciating what America offers.

My roommate lived in Niigata for 6 months and although his very limited view on Japan irritates me time to time, he came back sick and he says now he appreciates America more.

So just like others say, go light gear for the first time and if you really like it, go back with your other belongings.
