There are 9 schools, or ryuha to give them their Japanese name that are
considered Ninja schools
1. TOGAKURE RYU NINPO
2. GYOKKO RYU KOSHIJUTSU
3. KOTO RYU KOPPOJUTSU
4. KUKI SHINDEN RYU HAPPO HIKEN
5. KUMOGAKURE RYU NINJUTSU
6. GIKAN RYU KOPPOJUTSU
7. SHINDEN FUDO RYU DAKENTAIJUTSU
8. GYOKIJSHIN RYU NINPO
9. TAKAGI YOSHIN RYU JUTAIJUTSU
only 3 of these are actually “ninjutsu” or ninpo in the truest
the other 6 were MAs practiced by Ninja clan that became complete
schools – some are based on Kempo, some of Japanese JJ or Kenjutsu
What makes them “Ninja” is that they were used by the Ninja against the samurai,
tactics preceding techniques as always
It is not necessary to go into any real depth with these schools early in your career, but they may be referred to in class
this is similar to how a shuto is done different in kempo to kyukushin karate to shotokan and why taijutsu’s kiten ken is a unique technique not a variation on karate or kempo’s shuto.
The core of our practice comes from the Gyokko ryu of Koshijutsu, a unique
unarmed combat system similar to Kempo Jujutsu.
We back this up with the weapons system of the Kukkushinden ryu school of Happo Hikenjutsu. Primarily a sword school it focusses on the short straight Ninja-to and the 3 foot hanbo staff.
We also practice techniques from other ninja schools such as the bone breaking of Koto ryu koppojutsu and the chokes and strangles of Takagi yoshin ryu jutaijutsu.
