National Female ninjutsu practitioners showcase their skills

 While there is an international martial arts organization representing several modern styles of ninjutsu, the historical lineage of these styles is disputed. Some schools claim to be the only legitimate heir of the art, but ninjutsu is not centralized like modernized martial arts such as judo or karate. Togakure-ryū claims to be the oldest recorded form of ninjutsu, and claims to have survived past the 16th century.
