Bujinkan Budo Taijutsu is an amalgamation of 9 very traditional ancient Japanese martial arts dating back over 900 years. Some Ninjutsu schools some Samurai schools, developed to be a very powerful and effective self-defence system, making one of the very few true martial arts, not a sport with rules, regulations and referees. But simple pragmatic techniques, all practised in such a way to prevent injury and danger. Both physical and philosophical methods are practised in a safe manner. Some of the details and specifics regarding the origins of Ninjutsu are clouded in mystery, as that was likely a necessary element of survival for practitioners at the time. Ninjutsu has been sensationalized by Hollywood to depict Ninjas as assassins and spies, which is not what they were.
