Bujinkan Ninjustu is traditionally associated with the martial arts, strategies and tactics of the Shinobi (commonly known as the Ninja).  

Under the guidance of Grand Master Masaaki Hatsumi at the Hombo Dojo in Japan, the Bujinkan organization comprises nine schools that are descended from historical samurai and ninja schools dating back 900 years, that are collectively known as Bujinkan Budo Taijutsu.
