The purpose of Seizon Ryu Combat Jujitsu is to teach adults of all ages and skill levels a solid means of self defense in "Street" situations. We teach what is referred to as Genjitsu or Reality Technique.

The art incorporates various methods of striking, blocking, parrying, footwork, throwing, evading, choking, joint locking, weapons defense and ground work. Other martial arts styles that are currently integrated into the system include Western Boxing, Muay Thai, Shotokan Karate, Judo, Aikido, and Bujustu (simply meaning martial art)
