Japan has two totally different faces. There's the business-minded part... the work ethic, the strict politeness that you are hit with whenever you enter a store. The desire for schedule, efficiency, and perfection following a very logical path.
Then, as we see through their entertainment world, many fight off that stigma. The utterly ridiculous nature of their variety shows depicts an extreme opposite that is probably created out of necessity. Gut-busting, no seriousness at all humor, so that the masses can feel a little less suicidal (man the suicide rate of Tokyo is ridiculous). Also, a more intentional reaction to the world of strict logic, can be found in what the writers of Japan produce. If only based on anime, you can find that most of their anime/manga go in the other direction, obsessed with the strength of willpower and thinking with the heart first over the logical route. Hell, jumping in head first is GLORIFIED in Gurren Lagann to the point where the only competent person in government is vilified for not "BELIEVING" in blind willpower.
The whole country is at odds with each other on what they really want to believe in. Perhaps there'll be a change once the younger generation becomes the older generation. Or they'll just escape using the same means the older generation does... after-work drinking.
