Sony’s been talking about how they’ve overtaken the Xbox 360 here in the States, perhaps this is because Microsoft shifted their attention to pwning them in Japan? Xbox 360 sold 25,000 units to PlayStation 3‘s minor 9,673 units according to Edge Online, that’s 2.5 times more if you’re into that math thing.
Seriously though, Microsoft didn’t really shift any effort, they just got a Japanese style game called Tales of Vesperia from Namco Bandai. Go figure, when a Japanese focused game arrives for a console Japanese gamer will go out and buy it.
The big barrier to the 360 in Japan is the games and their contents. Microsoft is in tune with the needs and demands of the United States gamers, it usually involves FPS titles and excessive killing. Japanese gamers are not exactly huge FPS fans, we’ve seen the Asian community dominate in RTS style games (Starcraft is a great example) and they’ve always had interest in MMO’s, especially micro-transaction based games and we all know that’s the land of Final Fantasy. Is it so surprising the Xbox 360 moves off Japanese shelves when they have a game or two the gamers actually want to play?
This is only partly Microsoft’s fault, Microsoft doesn’t specialize in Japanese games anymore than Square Enix excels at western style games. The big difference? Square Enix doesn’t manufacturer its own console hardware. It is Microsoft’s console and they should have an interest in making games the Japanese people will like, thankfully Namco Bandai came through for them this time!

Don’t discount the releases of Blue Dragon, Lost Odyssey and Eternal Sonata earlier, that laid the groundwork, as well as Beautiful Katamari.
