I don't think so. I think Microsoft's main target is North America. They've taken some steps to try and grab a bigger chunk of the Japanese market, but for all their media prowess they just don't understand Japanese customers.
I think they'll stick to their strengths instead of trying to improve their weaknesses. If the Japanese audience is going to change its view of Microsoft, it will do so for the games on the Xbox 360, not the TGS showing.
