Right, but the region protection of disc-based games is in the executable (I believe), which cannot be modified (yet). Even though you'll be downloading the game from XBL, it's still a disc-based game, so the already-in-place protection will probably be exactly the same. If your plan doesn't work, you could try having the dude by it in Japan using *your* GamerTag, then either pop the HDD out of the case, or use an adapter (they're cheap) to hook the HDD up to an SATA port on a PC, copy the game, burn it to a disc/upload to the net, have you download it, put it on your 360's HDD (same way he got it off of his), and then play it using your GT signed into Live. This will only work if the protection isn't in the game, and you can't download it from Live. I'm sure given the relative close proximity to Hong Kong, these adapters should be easy to find in Japan. You could also simply send him your HDD, have him buy it on there (using your GT, again), then send it back. That would be the most plausible way of doing it.
