忍者 (にんじゃ) - Ninja

忍者, or 忍び (しのび - shinobi) as they are sometimes known, hardly need any introduction - they would have to be among the strongest associations people have with Japan. It's easy to see why - for as long as there's been a medium for them, these shadowy figures have been prowling our screens, books, comics, video games and imaginations. They can be faceless assassins, figures of fun or anti-heroes standing alone in the face of corruption. Invariably they're skilled fighters, but sometimes they border on being full-blown superheroes or magicians as well. The question is how much of 忍者 folklore is true and how much is pure fantasy; it might be the facts that surprise you most of all.
