At Okuden Karate Jutsu we concentrate on Karate's original purpose: practical self-defense against the full spectrum of violence. Our training methods differ significantly from those employed by Karate Do clubs, where sport, fitness and recreation are the primary goals. 

Karate Jutsu features escapes, vital point strikes, throws, strangulations/chokes, joint locks and prone grappling techniques that are absent from Karate Do, although some styles have broadened their technical range. The rise of Mixed Martial Arts (MMA) and the popularity of Brazilian Jujitsu has challenged the credibility of Karate Do as a fighting method. Conversely, Okinawan Karate Jutsu has been called the original MMA.

Karate Do developed on mainland Japan in the 1930's after Okinawan masters began teaching a simplified version of their secretive Karate Jutsu to mainland Japanese learners. This new Japanese art soon joined Judo and Kendo as a recreational activity that became especially popular among male university students. 

First generation Japanese Karate Do instructors began teaching Kata (forms) in a haphazard manner, leaving the students to interpret the meaning themselves. This is unsurprising since their Okinawan masters had shared little of the Kata's hidden purposes. Prior to this, Okinawan sensei had taught Kata to their private students at the end of a learning cycle to serve as memory exercises to reinforce previously-learned self-defense scenarios called bunkai jutsu. Some kata were comprehensive enough to be considered complete martial systems. 

Later, Western students of Japanese Karate Do sensei learned and taught Kata in the same haphazard fashion, leading to the further proliferation of unrealistic "bunkai". Their primary mistake was assuming that the Kata were meant to teach them to counter the predictable techniques of other Karate ka. They could not have known that the Kata were actually meant to help learners remember self-defense techniques against common attacks like seizing, choking, myriad strikes and combined acts of violence. 

Sensei Duchesney has been heavily-influenced by the work of Karate Jutsu researchers like Hanshi Patrick McCarthy, Sensei Vince Morris and Sensei Iain Abernathy. Their respective work has enabled countless learners to perceive Karate as a comprehensive self-defense system.   

Sensei Duchesney employs safe methods of imparting self-defense skills and physical fitness in a respectful atmosphere. Each class also features meditation, flexibility exercises and strength-building drills. All self-defense techniques are modified to suit the individual learner. Students also learn personal security strategies for modern urban life.
