Is 360 hate in Japan still because of the war?

[Reasonable]

Because of the war? I doubt it, they eat up plenty of other US output.

However, judging by some of the comments on this thread I wouldn't blame them if they did.

Brand, image and reliability, coupled with correct approach have been the problem. As we saw when MS put money behind relevant games, etc. the 360 saw a decent spike.

MS problem is that they will have to spend way, way above the return for a long time to really get anywhere in Japan with 360, particularly with Nintendo resurgent and Sony still hanging on above them even with less jRPGs, etc.
