In a recent poll that Xbox 360 garnered 5.8% support in Japan. Kind of a small number, I know. But you can look at it in two different ways. That is an increase of almost 4% as in the last poll the Xbox 360 only had the interest of 2% of the survey respondents. As usual Microsoft is using its skill in advertising to its advantage.
The Xbox 360 should be a great machine, so I am not surprised interest is increasing.
