Ninjas would carry crickets or cicadas to disguise their sound when they needed.

7 Things you didn’t know about Ninja

Imposing figures in black, hiding in the shadows, and moving about with almost superhuman agility seem like nothing but cool stories told to tourists and movie-goers nowadays, but were once a very real part of feudal Japan. Japanese folklore states that the Ninja descended from a demon that was half man and half crow. Logic would dictate, however, that it seems more likely that the ninja slowly came about as an opposing force to their upper-class contemporaries, the Samurai, in early feudal Japan.

    Murphy’s law tells me that when you want them to be loud they’re silent in defiance

    I’d like to see this become a requirement for American Ninja Warrior

    Too my knowledge ninjas are a recent term. They certainly had assassins and the like. But their were no “ninja families” or “hardcore ninja training”. It was just assassins who were japanese.
