As someone who has done both, I would recommend studying even for jsut a year before you go. What you can learn in the first year or two will save hours, weeks, and months of heartache and frustration. If you were going for a week or two, I would just say "GO!" but if you are planning a long-term visit, by all means, start learning Japanese basics today. You will thank yourself.

Many foreign musicians find work in Japan (if they have talent) and it can make for a nice side business and fun hobby. I played with a couple bands in Japan (I was the only gaijin, and i played drums or percussion) and I didn't do it for the money (as there wasn't much) but for the chance to perform and meet people.

All the big names in America and Europe are well known in Japan...
