The marital art of Bujinkan Budō Taijutsu draws from a number of classical martial arts schools, principally:
- Togakure Ryū Ninpō
- Kotō Ryū Koppōjutsu
- Gyokko Ryū Kosshijutsu
- Kukishinden Ryū Bujutsu
- Takagi Yoshin Ryū Jūtaijutsu
- Shinden Fudō Ryū Dakentaijutsu
- Gyokushin Ryū Ninpō
- Gikan Ryū Koppōjutsu
- Kumogakure Ryū Ninpō
Of this vast array of knowledge, the most widely disseminated and studied information is that of the unarmed techniques of Togakure Ryū Ninpō, Kotō Ryū Koppōjutsu, Gyokko Ryū Kosshijutsu, Kukishinden Ryū Dakentaijutsu, Takagi Yoshin Ryū Jūtaijutsu and Shinden Fudō Ryū Dakentaijutsu. In addition the various weapons of Kukishinden Ryū Happo Biken and sword system of Togakure Ryū Ninpō are also commonly practised.
In the Bujinkan Shugyō Dōjō we emphasize the study of individual schools and weapons, technique by technique, level by level, so that students can get a solid understanding of the foundations of the art.
