About Jim "Ronin" Harrison

Updated: Feb 18, 2019

More about the legendary fighter, master of Judo, Karate, Kickboxing, and creator of the Bushidokan System.

For many, the name Jim Harrison is as familiar as other legends of his time such as Bruce Lee or Chuck Norris. For others, who aren't as familiar with the Blood and Guts era of martial arts, his name may not ring any bells. Without a doubt, Jim Harrison was one of the toughest and hardest training competitors of his day.


Jim Harrison began his karate training in shorin-ryu under St. Louis, Mo. Karate pioneer Jim Wax, under whom he received his black belt.


He went on to become a Special Operations police officer in St. Louis. He served on a ‘Special Violence Squad’ that was sent into the ghettos after the most dangerous criminals.


Perhaps his most legendary feat of toughness during that time was when as a police officer, he was ambushed by an ex-con who came out of a bathroom stall and fired a high caliber pistol at Harrison through the bathroom stall door, striking him several times in the chest. Harrison and his partner managed to subdue his attacker before he passed out from his wounds. The close range shots kept him down for a while but he recovered and came back stronger than ever.


His experience in this field is what led to the creation of his devastatingly effective self-defense system, Ronin Goshin Jutsu.


Jim Harrison was known for both hitting hard and taking hard hits. In 1970, during his first-ever, full-contact bout in Dallas, Texas, he received a cut from a glove lace over his eye. Attempts at taping failed to stop the bleeding. Finally, between rounds, a physician came into the ring, and without anesthetic stitched the wound. Harrison calmly laid on the floor of the ring during the stitching without a flinch, then went on to win the fight with a knockout.

As one veteran fighter said, “One of my ambitions is to knock Jim Harrison down and keep him down.” It has never happened.

A member of the elite USKA Trias International Society, Harrison garnered membership in the Official Karate Magazine’s 1979 Legion of Honor.


He was an AAU Regional Judo champion, 3-time U.S. Karate Champion, 3-time All-American Grand Champion, undefeated U.S. light-heavyweight Kickboxing Champion, and coach to the undefeated 1974-76 U.S. Professional Team.


In 2001, Jim Harrison was recognized as a Hanshi of U.S. Jujitsu and promoted to the rank of 9th Degree Black Belt in US Jujitsu and US Taiho Jutsu by the United States Jujitsu Federation (USJJF), The National Governing Body for Jujitsu in the United States of America. In February, 2005 he was awarded 9th Dan in traditional Kodokan Judo by the USJJF.Mr. Harrison’s Dan Ranks

As a fighter/teacher/instructor/coach, Sensei Harrison has few equals.

Perhaps the most feared of Harrison’s abilities was his Judo ability. Karate fighters who had not learned to fall had much to fear when facing Jim Harrison who was known to frequently dump his opponents with judo throws throughout the match. 


Sensei Harrison was known for many impressive and dangerous breaking feats, including shattering, with a shuto strike, a bottle full of gasoline with a lit wick that erupted into a ball of flame.

Harrison continues a long and successful career as teacher, coach, competitor, and promoter. Jim Harrison has made a Tremendous Contribution to the Gobal Martial Arts Community. His continued “Standard of Excellence” and his many great accomplishments in the Martial Arts are very noteworthy. Jim Harrison was and still is the voice of truth and continues to be known worldwide for his candor.
