One should also take into account "The Cult of Cute."  Japan is ground zero for the Cult of Cute. It started with Hello Kitty in the 1970s. Anyhoo, Girls in their 20s, or older, will dress like little girls because it is cute. Everyone wants to be cute.  So Poser renders from Japan are like that too. 

In Japan, they will have Big Eyed Aiko in bright colors and cute costume like Lolita, Maid, or Catgirl.
In America it's Naked Woman Warrior with big knockers in leather with Scary Weapon. 

imho, American is too yang. I am loving the Japanese style! I love cute! I love color! I love the Bishies! And the neo-Punk j-Rockers too! Yea Japan! ^^
