According to Inquirer
in the last week x360 managed this little miracle... I thought nobody wants an x360 in japan...
"INCREDIBLY, THE Xbox 360 outsold the Playstation 3 in Japan last week.
The Xbox 360 sold 17,673 fueled by Namco Bandai's Ace Combat 6: Fires of Liberation, which debuted at the number two spot behind Super Mario Galaxy on the Nintendo Wii.
The PS3 sold only 17,434 units a slight 200 unit separation, but a significant increase over previous sales."
