I don't see why not. As long as your payment can go through a Japanese account, it should work.
I don't understand though. Why are you buying Mark of the Wolves to brush up for KOF XII? From what I remember on my Dreamcast copy, Mark of the Wolves does not play exactly like KOF.
My suggestion is you search for a copy of KOF 2002/2003 package that got released on the Xbox last generation. Check eBay and Gamestop. It's backwards compatible with the 360.
