“We expect the Xbox 360 to increase its Japanese market presence even more in the coming months,” Square Enix’s Shinji Hashimoto, producer on Einhänder and Kingdom Hearts 2, tells us. “There is a growing interest in Xbox 360 among Japanese users, due to the release of familiar titles, the increasing appeal of overseas titles, and the excellent reputation of the Xbox 360’s network services.”

It's true the 360 has seen quite a good steady increase in sales this past year, this week the Xbox 360 sold 15,474 units, a nice little bump from last week, due to the release of The Last Remnant. I think it's good that a developer like Square Enix has confidence in the console, i think it's vital for Square Enix that HD platforms don't become obsolete in Japan (under Nintendo's onslaught)
