Bujinkan Budo Taijutsu (武神館武道体術) is a system of Japanese martial arts that emphasizes the natural movement of the body. It encompasses armed and unarmed combat techniques against single or multiple enemies. By prioritizing personal growth over competency, the Bujinkan incorporates techniques honed over centuries. Founded by Grandmaster Masaaki Hatsumi, it encompasses nine traditional martial arts, some dating back more than 900 years. These are:

1. Togakure Ryu Ninpo – 戸隠流忍法
2. Kumogakure Ryu Ninpo – 雲隠流忍法
3. Gyokushin Ryu Ninpo – 玉心流忍法
4. Gyokko Ryu Koshi Jutsu – 玉虎流骨指術
5. Koto Ryu Koppo Jutsu – 虎倒流骨法術
6. Gikan Ryu Koppo Jutsu – 義鑑流骨法術
7. Shinden Fudo Ryu Dakentai Jutsu – 神伝不動流打拳体術
8. Takagi Yoshin Ryu Jutai Jutsu – 高木揚心流柔体術
9. Kuki Shinden Ryu Happo Hiken Jutsu- 九鬼神伝流八法秘剣術

Each school has different techniques, history, and philosophy, but they are unified under the Bujinkan Budo TaiJutsu umbrella.
