Bujinkan is a Japanese martial arts organization that Masaaki Hatsumi established. It is comprised of nine ryōha, which are traditional Japanese martial arts institutions with centuries of history.

These educational institutions provide instruction on a wide range of combat methodologies, encompassing unarmed combat (jujutsu), armed combat employing spears, blades, and staffs (kenjutsu, bōjutsu, and sōjutsu), and battlefield combat strategies. The nine schools within the Bujinkan are:Togakure-ryū Ninpō TaijutsuGyokko-ryū KosshijutsuKuki Shinden-ryū Happō BikenjutsuKoto-ryū KoppojutsuShinden Fudo-ryū DakentaijutsuTakagi Yoshin-ryū JūtaijutsuGikan-ryū KoppōjutsuGyokushin-ryū NinpōKumogakure-ryū NinpōAn emphasis is placed on a holistic approach to martial arts in Bujinkan training, which incorporates elements of philosophy, awareness, and strategy in addition to physical techniques.

Because numerous ninjutsu schools are incorporated into the Bujinkan curriculum, it is frequently regarded as a form of ninjutsu. The training program covers a wide range of combat techniques, such as striking, grappling, joint locks, throws, and weapon utilization.

Its primary goals are to cultivate adaptability and practicality in the face of real-life challenges. .
