My comment still applies. If you're going to a local store, then they are obviously not going to sell the Japanese version of the game (assuming you don't live in Japan). If I go to Target and pick up MKW, it's going to be NTSC-US obviously since I live in that region. So you don't need to worry about what region the game is unless you're buying the game online through Amazon or something. Then they should state what region it is in the title or something. If they don't, then ask.
Ok thanks.
