No, it is because Japanese game players aren't interested in the types of non-interesting games that the 360 primarily tries to bring to the market -- multiplayer shooters and corridor crawling fp rpgs that don't feature interesting characters and stories. Thank the maker that there exists a market that prefers more literary, artistic, or cinematic games -- something that really hasn't dominated the western game market since the days of Infocom and then the very jrpg like imo graphical adventures like King's Quest series from Sierra and Loom and Monkey Island from Lucas Arts or I wouldn't have much of an interest in this hobby.
On the other hand many in the US do prefer the 360 simply because it is made in America features patriotic themed games like the majority of the shooters and after years of hearing from their grandparents and / or great grandparents about how the Japanese attacked them at Pearl Harbor. Luckily, the Others market balances things out.
Heavens to Murgatoids.
