Going through my overflowing box o' filing. Found a dead interesting article from last year's NYT: From a Mushroom Cloud, a Burst of Art Reflecting Japan's Psyche. (Grab a login and password from bugmenot.com if you don't want to register.)
"Mr. Murakami holds that these traumas [atomic bombs and American occupation] have created a lot of displaced emotions - anxiety, shame and a pervasive sense of impotence - that have found their outlets in popular culture... These feelings are reflected in two opposing tendencies. One is a fascination with violence and power, visible in the building-crunching monsters and mushroom-cloud explosions frequently used in Japanese animation. The opposite pole is an infantalizing sense of powerlessness that is played out in the obsession with what is called kawaii, or cute, as exemplified by Hello Kitty and other irresistible characters."
