It is an unfortunate situation that you find yourself in and I sympathize. Unfortunately I don't see a legacy to non-legacy transfer happening any time soon. Square enix made it quite clear even before the game was launched that it would not be possible to transfer to non legacy from legacy for quite some time. In addition, they allowed legacy players to select their server before the game was launched, so the only reason you would be stuck on a Japanese server is because either you selected that server or you didn't realize that you could select which legacy server to start on. I guess from square enix's point of view, your friends could have started on your legacy server or they could all transfer to you, which sucks.
