Gyokko Ryû Koshijutsu

"School of the Jewel Tiger"

Dr. Hatsumi is the 28th Soke.

It is the oldest of the Bukinkan Schools



The school is known for its koshijutsu which places an emphasis on
striking weak and vital areas of the body such as muscles and soft
organs and for using fingers and thumbs for ripping and tearing. The
oldest of the nine traditions, this school forms much of the
fundamentals for the Bujinkan training including the kihon happo, muto
dori, and sanshin no kata. Its movement favors indirect attacks which
tend to be spherical and small techniques that often flank the
opponent. The ryu is a complete fighting method encompassing
koshijutsu which consists mainly of strikes and joint locks with some
throws, along with other skills such as Shuriken jutsu (throwing
blades), Ken jutsu (sword arts), and Kyoketsushoge (sickle and
weighted rope). It has been said that Gyokko Ryu along with Koto Ryu
make up 50% of Bujinkan training because of how well they compliment
each other using direct and indirect methods of attack. Cho Gyokko
originally founded Gyokko Ryu when he fled China during the Tang
Dynasty around 900 AD.


The Nine Rules of the Gyokko Ryû:

1. The Character NIN means to guard the nation even with one's life.

2. Forget self, be patient, feat not dying.

3. In danger say or show nothing

4. As a strong enemy comes at you, keep indomitable.

5. Serve and protect the master, as you must your parents.

6. Vices dissipate your proficiency.

7. Being drunk affects your judgement.

8. Destroy the enemy's power but leave his life.

9. To others teach not without the master's permission.
