Isn't it telling that many great Japanese authors and innovators in fields of the arts commit suicide? Is the soul that stems from Japan that of smothered despair at the dropping of nuclear bombs, US occupation and the fall of the royalty?
Japan tried to combine domestic and foreign Western in a manner that would keep the two separate. The result was fascism. Then they started to satirise and ironise themselves to greater lengths. The result is that young people in their society have stopped suspending their disbelief.
In the Netherlands, our spirit is entrepreneurial. In the US, their spirit is egalitarian. In Italy, their spirit is temporal.
In Japan... you have hyperultrapopular media which has exhausted itself and a xenophobic and isolationist electorate.
On one side they produce a lot of food, drink, media etc. etc. products and commerce, but they also don't have anything else going for them.
Anno makes NGE, a sort of monument to depression and tries to subvert otaku expectations, only to kickstart the greatest otaku icon the world has seen.
Miyazaki makes animation with purpose, that is art, and it becomes the technical and vaguely moralistic inspiration from alien things that deceitfully claim to be 'anime'.
All I can say is that Japan lives in half-apathy, half-ignorance with a sugary glaze of high quality products.
Name one thing Japanese post-WWII which isn't either lamenting irony or ironic.
