What is Nokido Jujitsu?

no-ki-do (pronounced: no-key-doh) (Japanese) literally translates in English as “of spirit way” which means “the way of the spirit”.

ju-jit-su (pronounced: joo-jit-soo) (Japanese) – noun –  a method developed in Japan of defending oneself without the use of weapons by using the strength and weight of an adversary to disable him.

While the true origin of Ju-Jitsu/Jiu-Jitsu/Ju-Jutsu is not clear, the practice of Ju-Jitsu methods can be dated before Christ.  Many different theories exist about Ju-Jitsu originating in India, China, and Japan.  Japanese Ju-Jitsu grew during the Feudal era of Japan and was expanded by the Samurai Warriors.  There are hundreds of different Ju-Jitsu styles that have been documented and are practiced even today, one of which is our style of Ju-Jitsu, Nokido Ju-Jitsu.  Ju-Jitsu has also produced many other styles of Martial Arts including Judo, Aikido, Aikijutsu, Russian Sambo, and Brazilian Jiu-Jitsu.  Ju-Jitsu, the Samurai’s Martial Art is said to be the father of all Japanese Martial Arts.

For a more in depth look at the history of Ju-Jitsu check out the article on Wikipedia.

Nokido Ju-Jitsu can be traced to the Nokido Shrine in the town of Kamo-Cho located in the Tsuyama prefecture, just as the Shinto Yoshin Ryu style of Ju-Jitsu can be traced to the Shinto Shrines.  It is currently unknown how long Nokido Ju-Jitsu has been in existence.


Hanshi Andrew Gruenwald was the Director of Nokido Ju-Jitsu in the United States until the year 2000 when he passed away from a brain tumor. Hanshi Gruenwald studied the Martial Arts while stationed in Japan serving in the U.S. Army Special Forces. Sensei Gruenwald made frequent trips back to Japan to continue his studies after returning to the United States to pursue a career in Law Enforcement. Hanshi Gruenwald opened two Martial Art schools in the Chicago Area. Hanshi Gruenwald was a Hachidan, (8th Degree Black Belt) in Nokido Ju-Jitsu and Isshin –Ryu Karate and a Shichidan (7th Degree) in Judo. Hanshi Gruenwald was posthumously promoted to 9th Degree Black Belt by Nokido Ju-Jitsu in 2010, ten years after his death.  Hanshi Gruenwald improved Nokido Ju-Jitsu by blending the best techniques from all of the different styles of Martial Arts that he studied.

Before Shihan Gruenwald passed away, he advised his Senior student Shihan Earl DelValle that it would be up to him to continue the teachings of Nokido Ju-Jitsu in the United States.  At that time Shihan DelValle was a 5th degree black belt and had learned most of the Nokido system from Hanshi Gruenwald.  Unfortunately much of the Japanese history of Nokido Ju-Jitsu was lost upon the passing of Hanshi Gruenwald.  Since 2000, Shihan DelValle has continued to improve Nokido Ju-Jitsu by adding effective techniques from the different styles of Martial Arts he has studied such as Judo, Aikido, Shito Ryu Karate, Defensive Tactics and Brazilian Jiu-Jitsu.

In 2001 Nokido Ju-Jitsu was certified by the United States Ju-Jitsu Federation and International Ju-Jitsu Federation.  Since 2001, Nokido Ju-Jitsu has produced many Judo and Ju-Jitsu champions, including National Champions.  Nokido Ju-Jitsu is also certified by the USJA, Wolf Pack BJJ, and Jujitsu America.  Nokido Ju-Jitsu continues to move forward through its students and teachers.  As they progress and improve, so will the style of Nokido Ju-Jitsu, “The way of the Spirit”.

Nokido Jujitsu Ranking Structure

Almost every Martial Art has its own version of a belt system, with the Black Belt and White Belt being present in almost every style.  The belt system concept has only been around since 1886, which is very recent considering Martial Arts training (formal and informal) has been around for as long as humans have walked the planet.  Judo founder Dr. Jigoro Kano was the first person to signify martial arts ranking with a cotton belt.  It should be noted that belts/ranks are not transferable between the different styles of martial arts and each art is vastly different with it’s requirements for rank advancement.

Our style of Ju-Jitsu follows a fairly common belt progression for under ranks and follows the Judo belt structure for the black belt ranks.  Ranks are based on ability level of student, knowledge of required material, time in grade, age of the student, ability in randori/sport/grappling and commitment to Nokido Ju-Jitsu.  Like in most arts each color belt up to brown represents a single level at the class (kyu) ranks. Junior Ranks are divided into the Solid belt with a black horizontal stripe.  Brown belt has three levels and is considered an advanced level regarding skill in Ju-Jitsu/Judo.

Black belt is a substantial rank for the Nokido style and takes an average adult a minimum of five years to obtain with regular training.  When an individual reaches 1st Degree Black belt in Nokido Ju-Jitsu they will receive ranking in both Traditional Ju-Jitsu (Nokido) and in Judo. At 4th Degree Black Belt one is considered an expert technician and may wear a black and red panel belt.  Expert status comes after about 10 years of hard training at the black belt level.  When one reaches 6th Degree Black Belt one may wear a white and red panel belt which signifies a master teacher.  This follows the tradition of Judo.

Red belt is the highest rank in Nokido Ju-Jitsu and is awarded at 9th Degree Black Belt.  Red belt represents Senior Master and one should expect to be involved with Nokido Ju-Jitsu for 50 years to obtain this status.

Below is a more detailed list of the progression and classification of each rank in Nokido Ju-Jitsu.

NEW STUDENT – White Belt (10th Class)
Student learns rules of class, class etiquette, base stances and movements, how to break fall, and is introduced to throws/ joint locks/grappling/hand strikes/kicks.

BEGINNER LEVEL – Grey/Yellow/Orange Belt (9th – 7th Class)
Student begins to use basic moves in randori (sparring) and starts to build knowledge base of throws/joint locks/chokes/grappling/hand strikes/kicks.

INTERMEDIATE LEVEL – Green/Blue/Purple Belt (6th – 4th Class)
Student continues to build knowledge base and begins to learn more complex moves and counters.

ADVANCED LEVEL – Brown Belt (3rd – 1st Class)
Student has a vast knowledge base and is learning how to use multiple counters/attacks in randori without exerting much effort.  Brown Belts are held to a higher standard and must begin to assist with instruction.

SKILLED TECHNICIAN – Black Belt (1st – 3rd Dan)
Student has become very proficient with standing and ground combat.  At this stage student is molding the art into their own personal style of Ju-Jitsu.  A student must be at least 16 years old to be awarded black belt status.

EXPERT TECHNICIAN – Black & Red Panel Belt (4th – 5th Dan)
Student/Teacher has the majority of moves and concepts of the Nokido system and is still refining the art to his/her physical and mental abilities.

SENIOR MASTER TEACHER – Red Belt (9th – 10th Dan)
