The BBC News Web site featured an interesting story about the Race Girls a few years back. Below are some informative excerpts:
No Japanese race is complete without a parade of race queens, long-legged models in daringly skimpy costumes adorned with the colours of their team and its sponsor.
The race queens attract a lot more attention than the cars, attracting devoted fans who jostle to snap photographs of their idols.
Race queens embody the cult of 'kawaii' or cuteness, which you see all over Japan, peddling an image of doll-like beauty and unobtainable sexuality.
