The Selection of the Name Rônin®

As founder of the Goju-Ryu based Karate system Named “Rônin Goju-Ryu Kai World Karate Organization®”, I felt compelled to conduct extensive research on the true meaning of the word “RÔNIN”. The term “Rônin” was given to most “Samurai” Warriors (the word Samurai can be translated as Retainer or a form of Warrior Servant) of the “Bushi” class, who did not serve a particular master, because the latter was dead, or because his land had been confiscated, or embraced a religion or way of life that do not require the services of these personal guards or soldiers. Copyrights Reserved®

Some of these Rônin became martial arts instructors (Sensei), bodyguards (Yoyimbo), protectors of villages (Damyo), etc. Many Martial Arts Schools (Ryu) were created by a Ronin. Musashi Miyamoto (1584-1645) was the most famous of them all. During 1701-1703 the famous forty-seven (47) Rônin in the service of Asano, Lord of Ako, waited for approximately two (2) years for the opportunity to avenge the death of their lord/master, who was obliged to commit seppuku/suicide by orders of Shogun Tokugawa after an incident between lords Asano and Kira. But 47 of Asano’s most faithful Samurai, now Rônin, resolved to avenge his death on Kira. On December 14th, 1703, after avenging his death, all 47 Ronin surrender themselves to the authorities and committed seppuku on the orders of the Shogun in front of Asano’s tomb, on February 4th, 1703.

The people acclaimed them as heroes and became “…the symbol of courage, honor and loyalty” As a martial artist I always value these three virtues of Courage, Honor and Loyalty as shown by these Faithful Warriors. This is why I selected Rônin® as the name of our Brotherhood, the Rônin Brotherhood®, home of Rônin Goju Ryu Kai World Karate Organization®, International Rônin Martial Arts Federation®, Rônin Police Defensive Tactics Instructor Association® and of course “Team Rônin®”.

Goju Ryu Karate-Do:
A Lineage of Tradition And Excellence

Goju (Go “Hard” & Ju “Soft”) Ryu Karate is a traditional Martial Art with a very well defined history, and lineage of succession traceable to the roots of the predecessor (Kanryo Higashionna) of its founder Chojun Miyagi to this date.

Yamaguchi Gogen Sensei was the personal disciple (Deshi) of Miyagi O’Sensei, he initiated and trained Master Peter Urban into the path of Budo as its conceived through the eyes of Goju Karate.

This uncontaminated line of succession allows for a pure transmission of knowledge in a fashion that establishes a direct connection to the ancient wisdom of the battlefields of yesterday in Okinawa and Japan to today’s modern warriors. Copyrights Reserved®

Goju-Ryu Karate remains and effective and powerful fighting method today. The original concept of Goju Ryu Karate was to create a powerful combat system that developed strong fighters, on their hands and on their souls.

Rônin Goju Ryu Kai maintains a clear commitment to the preservation of the tradition of the Goju Karate created by Miyagi O’Sensei, but incorporates fighting methods and self defense techniques that are in tune with the critical and violent demands of today’s street survival.

Katas, Ibuki, Tai-Sabaki, Taiso, Kata-Kihon, preserves the old Secrets of empty-hand combat and Fitness encompassed in an elegant Style of rich Martial Tradition…

Kyoshi Jesus Cendán / Executive Board Advisor

Kyoshi Jesus Cendán 7th Degree – Nanadan

Kyoshi Jesus Cendan began his Martial Arts training in 1976 under the teachings of Sensei Claudio Gonzalez in Union City, New Jersey; at the time he was 13 years old. Sensei Claudio Gonzalez was teaching Goju Ryu Karate-Do. Once there, Kyoshi Cendan (who prefers to be called Sensei) remained in the school until he was tested and awarded his green belt. Sensei Cendan’s family had to move away to initiate a new job related venture and he was forced to pause his Karate training for a short while. Some eighteen (18) months later Sensei Cendan met a young man who was taking some Karate lessons with an instructor by the name of Kevin Norlander. Sensei Cendan asked the young man if he could take classes with his instructor, to which his new acquaintance replied that he would have to check “because his instructor did not teach everyone” and “any new student would have to be brought by a black belt to join in the classes”. “Lucky for me” Sensei Cendan said, “the young man was one of that Sensei’s black belts”. Sensei Cendan was later told that he was allowed to join this karate group.

According to Sensei Cendan’s own words: “I was also happy to know that this Sensei was also a Goju Ryu style practitioner, I could not believe how lucky I was”. Short after beginning training in Goju Ryu Karate-Do, Sensei Cendan discovered that Sensei Norlander was a direct student of Hanshi Peter Urban the founder of USAGA, and considered by many as the father of American Goju, a student and friend of Hanshi Gogen “The Cat” Yamaguchi, who was in turn a student and friend of Goju Ryu Karate-Do Founder O’Sensei Chojun Miyagi. At the time Sensei Norlander was living with Grand Master Urban. Upon interview with Sensei Jesus Cendan he referred to those days: “What a great time this was! Being able to spend time with such great Martial Artists, like Hanshi Peter Urban, and my Sensei Kevin Norlander”.

Although Sensei Cendan was a student of Sensei Norlander he had extensive opportunity to train under the direct supervision of Hanshi Peter Urban. According to Sensei Cendan the best thing about training with his Sensei was that he did not charge any money to teach him, but according to Sensei Cendan’s words: “Wow, I thought this was great but oh boy! you had to do lots of things for the Sensei, start with all his chores around his home, that meant doing everything, cleaning the house, going shopping, washing his car, cleaning his clothing and any job he had at home, you had to do it!” “At times I thought to myself, it would have been easier to pay money than to do all these chores”, “As years passed I learned the true meanings and intentions that Sensei had for me…” “I did this for many years and through it my Sensei and I developed the best teacher/student relationship that you can possibly imagine, he became my best friend and was always there when I needed him…”

In 1984 Sensei Cendan moved to Miami, by that time Sensei Cendan had already achieved the rank of Sandan (3rd Degree Black Belt) from his Sensei, friend and mentor, Kevin Norlander. Upon leaving to Miami, Sensei Norlander advised Sensei Cendan to find his old Dojo brother Hanshi Manuel “Manny” Savedra. Sensei Cendan had met Hanshi Manuel Saavedra many years earlier, and he was taking into Hanshi’s organization like one of the family. Under the tutelage and guidance of Hanshi Manuel Saavedra, Sensei Jesus Cendan obtained the rank of Shihan (6th degree black belt), it was during this time that Sensei Cendan met Hanshi Carlos H. Montalvo at the famous “Calle Ocho Dojo” (Miami’s 8th street Training Hall). Sensei Jesus Cendan remained under the tutelage of his teacher and friend Hanshi Manuel Saavedra’s until Hanshi’s departure to New York in 1999.

After Hanshi Saavedra’s departure, Sensei Cendan remained by Hanshi Carlos H. Montalvo’s side assisting him in the organization of the institution created by Hanshi Saavedra. After a series of events, Hanshi Carlos Montalvo decided to start a Goju Ryu based system that would re-discover the ancient values secreted in the ancient tradition that embodies Goju. This new system was based on the concept of rescuing the old tradition of training and incorporating the close quarter combat techniques encompassed in Goju combining Hanshi Montalvo’s real street survival experience as a Federal Agent, and his World Class competitor skills, to form a style that is strong in combat, with real applications for Self-defense and graceful and effective for competition. All this was possible in part with the direct support and great ideas, provided by the sea of knowledge and courage of Sensei Jesus Cendan. Between Hanshi Carlos H. Montalvo, Sensei Jesus Cendan and with the wisdom, support and guidance of Renshi Joseph E. Benitez, the three Goju practitioners and friends gave birth in the year of the Dragon (2000) to the concept that later came to be known as Rônin Goju Ryu Kai World Karate Organization and the Rônin Brotherhood, LLC.

On 2008, Sensei Cendan was promoted to the 7th Dan (Nanadan) by Hanshi Montalvo.

Sensei Cendan, currently works in the security industry in South Florida, where he continues his search for Martial Arts knowledge, and lives without a doubt as a true Ronin warrior…
