This one's a little weird as far as regional stacks, because there appears to actually be two different "vanilla" versions as well, but that share an achievement list. I have two non-GOTY Oblivion's installed - US/NTSC and JP. I own the Shivering Isles for U.S. but, despite being the same list, it asks me to buy the Shivering Isles for the JP version.
Then, on top of that there's this GOTY version which is supposedly physical only - which seems right I don't see a digital listing anywhere. So as long as it's Japanese, Physical, and has the DLC bundled in on the disc or whatever, you should be good.
Fear is the mindkiller.
