About Seki-Ryu Jiu-Jitsu

Seki-Ryu Jiu-Jitsu, is the teachings of Seki Sanzo Sensei (1914-1998) and is rooted in the koryu bujutsu systems of Kito Ryu jiu-jitsu and Tenjin Shinyo-Ryu jiu-jitsu.

Kito-Ryu jiu-jitsu was founded by lbaraki Sensai around 1637. This school was particularly known for its outstanding Nage-Waza (throwing techniques) and emphasized mental training.

Tenjin Shinyo-Ryu jiu-jitsu, a nineteenth century jiu-jitsu ryuha, was founded by lso Mataemon Minamoto no Masatari around 1830. This style combined the teachings of Yoshin Ryu (1651) and Shin no Shindo Ryu (1770).  Tenjin Shinyo-Ryu was well known for its extensive Katame-Waza (holding, choking and joint locking techniques) and Atemi-Waza (striking techniques).

Seki Sensei studied these arts as a young man in Japan. Later he studied Kano jiu-jitsu (later to become judo). Kano jiu-jitsu is also rooted in the arts of Kito Ryu and Tenjin Shinyo-Ryu. Returning to the United States in his early twenties (around 1936), Seki Sensei worked several day jobs eventually working for Lockheed as a quality inspector. In the evenings he would teach and practice jiu-jitsu.

Wanting to refine and test his skills, Seki Sensei regularly participated in one-on-one contests against other martial artists. These contests were before the Ultimate Fighting Challenge (UFC) matches of today and had even fewer rules or restrictions. You basically signed a release form and the person that walked away from the mat was the victor. Seki Sensei fought in these matches two or more times a year for more than forty years undefeated.

Seki Sensei took what he learned from these matches and adjusted his curriculum and teaching methods to train his students. He taught his unique style of jiu-jitsu up to five nights a week and taught numerous weekend seminars at remote schools. His jiu-jitsu program at Los Angeles Valley College was the most successful of its kind, teaching thousands of students basic self-defense and producing dozens of black belts.

Jiu-Jitsu as taught by Seki Sensei, a form of suhada bujutsu (fighting with or without weapons, while dressed in everyday street clothes), is more a system of self­ defense than an art oriented toward battlefield combat. Its basic methods of attack and control include: hitting, striking, thrusting, punching, kicking, throwing, pinning or immobilizing, strangling or choking, joint-locking, and the occasional use of weapons. Defensive techniques include parrying or blocking strikes, thrusts and kicks, receiving throws or joint-locking techniques by learning how to fall safely and knowing how to “blend” to neutralize the technique’s effect, effecting a release from an enemy’s grasp, and changing or shifting position to evade or neutralize an enemy’s attack.

Seki-Ryu jiu-jitsu, utilizes many techniques, some of which are similar to those found in other martial arts like karate, aikido and judo. Both aikido and judo are modern day descendants of jiu-jitsu.
