Japan (still) hates America because 360 isn't selling? wow, thats grotesque. Ever heard of brand recognation, marketing, hardware durability, backward compatiblity? Even japanese 360 developer say microsofts japanese marketing sucks balls. If I'm not mistaken 360 games still sell better than ps3 games, with a 1/3 of it userbase.
Sony knows how to do marketing in japan and ps3 sells still are lacking. Ps3 basically sells on backwardcompatiblity, its brand and blu-ray alone. sure 360 has a far better gameslibrary, but most of them don't appeal to japanese. The situation with xbox 1 was a disaster; delayed releases, no localisation, scratched cds...
