Teen or middle-aged, working woman or housewife - all are here on a singular mission -- to slice their way to fitness and a measure of cool. These women may look lethal, but make no mistake about it: They're trying to create an illusion of a fight to the death for the benefit of an audience. They are practicing the art of "ta-te," or performance fighting. There's no scoring involved, and no competition. The idea is to put on as convincing a show as possible.

Her timing and rhythm are so exquisite, she can fend off a band of assailants even while blindfolded. Some might call this unnerving, but Takano calls it refreshing... "Performance fighting allows you to completely step away from your normal self," she said. Since the age of the samurai, back in the middle ages, Japanese men have been battling with swords. It's always been a male-only pursuit. But these 21st-century warriors say there's nothing cooler than women crossing swords.
