Apparently there is a chance that Square-Enix, RPG giant, famous for the Final Fantasy series is aiding in the publishing of Modern Warfare 2 in Japan.
A new http://www.square-enix.co.jp/2/ posted by Square-Enix, shows some Japanese text (sorry I can't read it so I couldn't translate it), and the familiar Modern Warfare "2". Also the legal info at the bottom of the site credits Activision.
This is just my opinion or view on the situation, but I believe that Square-Enix is helping to push Modern Warfare 2 in Japan, due to their strong following and support in the Final Fantasy series.
By selling the product with a widely known name, there is a chance for better coverage and spread of the product as well as targeting the company's main supporters.
