The difference between Brazilian Jiu-jitsu and Jujitsu

Japanese and Brazilian Jiu-Jitsu
“What is the difference between Japanese (classical) Jiu-Jitsu (jujutsu) and Brazilian Jiu-Jitsu?”
The first and most important reason can be found in the art’s history and is primary to all others discussed afterward. When you research the history of Brazilian Jiu-jitsu, you will understand that it came from “Judo” in its time of renaissance. In the early 1900’s, Judo was being developed from a variety of Jiu-jitsu styles in order to make it the most complete and effective martial art in the world. Some older Jiu-jitsu schools only focused on one area of fighting (some practiced primarily standing techniques) and had been left without a realistic battlefield testing ground for hundreds of years. If you recall the history of Judo’s beginning, you know that it was made up of mostly standing techniques at first, from Kito Ryu Jiu-jitsu and a few other styles. This alone was not enough, so the groundwork of Fusen Ryu was added, making it more complete. When you say “traditional” or “Japanese” Jiu-jitsu, you are referring to only one of these Jiu-jitsu styles, which is incomplete alone. When you say Brazilian Jiu-jitsu, you are referring to the best techniques from a wide variety of styles.
Our Jiu-Jitsu in the United States was underdeveloped compared to the Jiu-Jitsu in Brazil. Only now are we beginning to catch up, and we are still suffering from the inadequacies of the ‘older’ and more traditional schools of Jiu-Jitsu in this country. To give you an idea of what I mean, I’ll tell you a little about my training. I earned a black belt in a classical style of Jiu-Jitsu, which taught all the Judo throws of the Kodokan and Aikijitsu (the grandfather of Aikido). It was a great art, but one that could not be used on anyone with skill effectively before complete mastery. I was subsequently defeated by a student of Brazilian Jiu-Jitsu who was only at blue belt level, while I was a black belt in traditional Jiu-Jitsu. Why? Lack of realistic practice is the reason. There was too much of: “you stay perfectly still while I try an extravagant technique on you and you play along.” There are many techniques which is where Judo is great, and some traditional schools teach techniques that were designed thousands of years ago whose applications have not been modified or thought about since. Brazilian Jiu-Jitsu is simple to learn, so simple that a dedicated student of one year can easily beat martial artists of other styles who have many years of experience.
Some styles of martial arts spend hundreds of hours working on a rigid stance and one hundred standing techniques that cannot possibly be mastered in a reasonable amount of time. I once interviewed Royce Gracie and he gave a response that supports this point quite well:
“We don’t believe in teaching a ton of moves every class and the student walking away with limited knowledge. We prefer our students to know 20 techniques at 100%, than 100 techniques at 20%.”
(Interview with Gene Simco for www.jiu-jitsu.net)
Brazilian Jiu-Jitsu focuses on techniques that are easy to learn in a very short period of time. The techniques taught in Brazilian Jiu-Jitsu are also effective and have been tested on knowledgeable martial artists who are not cooperating. A small amount of simple but high percentage techniques makes the difference. If all you do is practice five or six techniques, you will be very good at them in a year or so, but if you have to divide your time between a hundred or more techniques, you will most likely be a jack of all trades and a master of none in a year’s time.
The differences in the two styles of Jiu-Jitsu are not necessarily in the technique, but in the practice and application. First of all, Brazilian Jiu-Jitsu has a very sophisticated ground-game, where Japanese Jiu-Jitsu places importance on standing techniques, as does Judo. Judo as a sport does not allow leg locks, where Brazilian Jiu-Jitsu does. Sport rules for Judo dictate that if a player has been pinned by his/her opponent for twenty-five seconds, he or she will lose the match. Brazilian Jiu-Jitsu has no time restraints on ground positions and stalling most often occurs while standing. Older styles of Jiu-Jitsu (often spelled jujutsu or jujitsu) are usually preceded with their style name or Ryu (the Japanese word for “style”). These Ryu of Jiu-Jitsu were developed long ago and have no sport application to allow them to develop technically. The lack of realistic practice is what makes some styles ineffective or obsolete.
To really understand the differences between Brazilian and Japanese Jiu-Jitsu, one must research the history of both arts. In particular the birthing of Brazilian Jiu-Jitsu by Carlos Gracie, Brazilian Jiu-Jitsu’s founder, who was an avid boxer. Most Japanese Jiu-Jitsu fighters were studying traditional Karate strikes, which are much different from that of a boxer. Maeda, the man who introduced Gracie to Jiu-Jitsu, was also a student of Judo, which at the time was considered an updated version of Jiu-Jitsu, or Kano ’s Jiu-Jitsu. As discussed previously, the Judo that the Gracie family was introduced to was a Judo whose focus had turned to ground fighting in recent years. This ground fighting came from only one style of Jiu-jitsu (Fusen Ryu), the other styles that made up Judo had not focused on ground work, so as their practice continued, they stayed to their traditional roots, which considered mainly of standing techniques. While older styles of Jiu-jitsu stuck to their core curriculums, Judo soon forgot about experience and turned its attention to gaining world wide exposure as an Olympic sport, which would eventually restrict the once great art and cause it to focus once again on primarily standing techniques. Maeda was also exposed to western wrestling, as he had encountered one wrestler in particular at the West Point Military Academy in New York, and had more experience fighting throughout Europe and the Americas than any other Japanese fighter of that time.
Brazilian Jiu-Jitsu is a progressive style of Jiu-Jitsu; once a technique is developed and used in competition, other Jiu-Jitsu players begin to design counters to that technique, and counters to those counters, which allows Brazilian Jiu-Jitsu to evolve freely. Brazilian Jiu-Jitsu players do not prepare for the untrained opponent; they assume that their opponent may be more technical.
The problem with some ‘older’ styles of Jiu-Jitsu is the same problem with old cars, or anything that has not been updated or modified. I earned a black belt in Japanese Jiu-Jitsu and now that I am at an advanced level of Brazilian Jiu-Jitsu, I notice the similarities and differences. Some of the self-defense movements are identical; it is typically in the groundwork (ne waza) where the Judo or Japanese Jiu-Jitsu practitioner lacks ability. It is for that reason I started training Brazilian Jiu-Jitsu.
Comparing “old” Jiu-Jitsu to “new” Jiu-Jitsu is like comparing old cars to new. Both a Ford Model-T and a Ferrari will do the same job, but a Ferrari will do it more efficiently. The ability of Jiu-Jitsu teachers can be compared to the mechanics certified to work on these cars; if you take a mechanic from 1910 and show him a Ferrari, some things would look familiar, but he would not understand the new design and complexity of the modern variation without proper training.
In the style of “Japanese” or Traditional Jiu-Jitsu I learned, not much is technically different. Brazilian Jiu-Jitsu has more techniques on the ground whereas Japanese Jiu-Jitsu has more standing techniques. What I like now about having plenty of experience in both styles is that I feel it has brought my technical level to a higher understanding. I know lots of little details and “tricks” or “secrets” within the techniques that you don’t see anywhere. I think that although things improve in the evolution of Jiu-Jitsu, you also lose some details that the “ancient” schools sometimes hold “secret”. Without proper modification, these “secrets” don’t mean much, but when you combine them with the refined practice of Brazilian Jiu-Jitsu, you’ve really got something. As I get higher in the ranks of Brazilian Jiu-Jitsu, I start to appreciate the Model T. I’m not so embarrassed of my “old” Black Belt in Japanese Jiu-Jitsu anymore, I’m actually learning to apply it. I know details of arm locks and chokes that I don’t see anywhere else. It is important to note, however, that I attribute my ability to apply the old Jiu-Jitsu to my advanced level in Brazilian Jiu-Jitsu.

Posted at 4:12 am | Filed Under brazil
Up until 30 years ago, JUDO was the martial art. Then with the introduction of the more mysterious martial arts with more of a “killing” edge to them this coupled with the focus of the USJF/USJI (the leading Judo organizations in the US and the world) focus on Olympic competition and the simple fact that training in judo is painful and to this day, very difficult to get a black belt rank in it, especially if you are in a competitive area. I could probably write another 5 pages on this, but I will stay on point.
During these years EVERY major metropolitan Police Department had a Judo club. Even countries like Thailand taught Judo to there police force, NOT Muay Thai. I personally train a number of law enforcement officers and I have seen the results first hand. So why is Judo the martial art for law enforcement?
The primary purpose of non-lethal force with law enforcement is to get your target to comply. What is the most realistic way of getting someone to do something you don’t want to with out seriously damaging them? How can you get someone from their feet to the ground as quickly as possible? How do you know what its going to be like for real? The answer is JUDO.
First off, when most people “resist” arrest, it’s an ego thing. They are looking to be restrain, or they don’t want to look like a punk and go quietly. The advantage the cop has is that the suspect knows that the officer is not trying to kill him or her. I realize this is a disadvantage in some situations, but that’s what the stuff @ www.thetruthaboutselfdefense.com is for.
First, the object of judo is to throw the opponent from his feet to his back. Think about the majority of the altercations policemen get in, most of the time the skel is just kind of testing the officer. Once the suspect feels that the officer is going to be a tough customer, he’ll comply. Nothing drives this point home better than taking someone from their feet to their ass with one shot. Usually, when the guy is on the ground, he’ll take his medicine, since he knows the cop really isn’t going to kill him, a lot of time, that’s all it takes. Plus, to witnesses, it just looks like you pushed or pulled him over; mean while, they hit the deck HARD. Just ask my friend who threw guys one night with sasae tsuri komi ashi (lifting, pulling, ankle throw). These guys were fighting each other, and the guys on the scene had to get them to stop. So, he got in the fray and tossed ‘em all. Well, I guess they felt that getting up and fighting again wasn’t that much of a priority.
A popular argument is that most fights go to the ground. This may be true, but most people don’t know what they are doing. Most people don’t study judo.
One of the primary components of judo is being able to stay on your feet. You develop this skill as a by-product of the training. Just gaining the ability to stay on your feet is worth the price of admission. Especially when you are in a ’scrum’ maintaining your balance is a primary concern.
The fact is, there is not better way to practice imposing your will on someone who is non compliant. Nothing gives you greater confidence than throwing a man that has 100 pounds on you. Nothing. Especially when that guy doesn’t want to be thrown.
Another important component is the pinning and submissions of judo. To secure a full point in judo you need to hold him on his back for 25 seconds. Being able to hold a man down until the cavalry arrives will save your life. Plus, while this guy struggles, you are just squeezing the life out of him. Trust me, when it comes time for you to put the cuffs on him, he’ll be as compliant as a wet noodle.
Strangles and arm-bars, yep, Judo has them too. If you have to put someone “out of commission” and you really want to know how to strangle someone who doesn’t want to be strangled, you’ve come to the right place. When they wake up, you will have them cuffed and ready to go. (Uh-oh, the choke hold alarm! Hey, I am not talking about liability; I am just trying to save your life).
Lastly the overall toughening and body conditioning is second to none. If you can “randori” for 30 minutes, non- stop - you’re in really good shape. So why aren’t some many people, knocking down the doors of every Judo club. Because it’s hard work and it hurts. There’s no junior black belt, student of the month. Your gi is white and the work is hard. No secrets, just hard work.
The irony and the tragedy: the guys who train with me are only a few. Most of the guys interested in this type of training are SWAT or tactical guys. Unfortunately, these guys are the least likely to get in a roll around. That’s the irony. The tragedy is the guys who are most likely to need good hand to hand fighting skills are the patrolmen doing car stops, domestic violence; and all of the first response details. By the time the SWAT shows up, the situation is intense and the reality of a hand to hand confrontation is highly unlikely if not damned near impossible.

The History of Brazilian Jiu-jitsu
Posted at 2:21 am | Filed Under brazil
Part 1
The Beginning
“Where did it all begin?”
I don’t think anyone can answer this question with certainty, but there are plenty of good hypotheses. Every culture has some form of hand to hand combat in its history. Combat without weapons usually appears in the form of wrestling and sometimes boxing. Looking at the history timeline, one good hypothesis is that the wrestling techniques of Jiu-Jitsu could very well have come from Ancient Greece. Olympic games were one of the Greek’s strongest traditions. It is most likely that along with Greek ideas, came one of its most popular sports, Pankration. Pankration was a sport that involved both boxing and wrestling techniques and became more popular to the Greeks than either of those sports individually. Pankration would later be overshadowed by the Roman Gladiators, and then banned from the Olympics by Christian leaders of the Roman Empire. Even though new rulers would come and go, Greek customs and ideas still reached India, where Jiu-Jitsu’s foundation was likely to have been born. During Alexander the Great’s conquests (356 - 323 B.C.), he brought the Greek culture to the areas he conquered. His conquests stretched all the way to India, where he introduced the customs and ideals of Greek culture to the people of that area. Jiu-Jitsu wasn’t being formally taught in Japan for over one thousand years after this. Many say that the Greek influence in India led to the development of Kung Fu or more appropriately, Wu Shu (martial arts) in China.
The Chinese have a great deal of stories to support the history of their martial arts. The general idea embraced by most historians is that systemized martial arts techniques came from India along with Buddhism (Bodhi Dharma). The concept here is that the Shaolin temple was built in the center of China and this is where Bodhi Dharma introduced Buddhism and Boxing (senzuikyo). (ref. Aikido and Chinese Martial Arts, Sugawara and Xing) The story that supports the idea of Jiu-Jitsu coming from China takes place around the time of the fall of the Ming Dynasty. It states that a man named Chingempin came from Japan to live in Tokyo at a Buddhist temple where he met three Ronin (masterless Samurai) named Fukuno, Isogai, and Miura. Chingempin told the Ronin of a grappling art he had seen in China. The Ronin became particularly interested in pursuing the study of this art, so he then began teaching in Japan, and this art became Jiu-Jitsu.
The next theory is that there was many forms of wrestling that had developed in China. One of the most notable is Horn Wrestling, called Jiaodixi. This form of wrestling was practiced by the Mongolians and later evolved into Jiaoli, which was wrestling without the horns. This form of wrestling can be seen in Native American cultures (evident in the typical Native American Buffalo head wear) and most likely arrived there by way of Mongolians migrating through now modern Alaska. Jiaoli evolved and became Xiangpu and it is said that this form of wrestling became Sumo in Japan. Another theory says that there were practitioners of Chikura Karube, a wrestling sport developed around 200 B.C. It is said that Chikura Karube later became Jiu-Jitsu in Japan.
The last story mentioned here is that Jiu-Jitsu is Japanese and from Japan. This story follows the same basic idea but differs in that Chingempin introduced an early form of Jiu-Jitsu (not yet called Jiu-Jitsu) called Kempo in Japan, which consisted mostly of strikes and very little grappling. From there, the Japanese developed it into a more effective grappling art. One thing is certain about these stories, and that is that the Japanese were responsible for refining a grappling art into a very sophisticated grappling system called Jiu-Jitsu.
Tracing the history of grappling techniques for this book was quite interesting. In doing so, I decided to look for some common threads between the stories, which are:
All ancient cultures had some form of grappling and unarmed fighting techniques.
The Greek culture gave its fighters the greatest financial and social rewards. The ancient Greeks conquered quite a bit of territory during the time of Alexander the Great, including the area that Jiu-Jitsu’s techniques were said to have come from.
Wrestling did exist in China and Mongolia before Jiu-Jitsu did in Japan, and it is interesting to note that this is where Native American wrestling most likely came from by way of migration over the Alaskan Ice Bridge.
The pinning and throwing techniques of Jiu-Jitsu are very similar to, and in some cases, the same as those of Greco Roman Wrestling.
Development of Jiu-Jitsu
Jiu-Jitsu itself was developed in Japan during the Feudal period. It was originally an art designed for warfare, but after the abolition of the Feudal system in Japan, certain modifications needed to be made to the art in order to make it suitable for practice. During Feudal times, Jiu-Jitsu was also known as Yawara, Hakuda, Kogusoko, and an assortment of other names. The earliest recorded use of the word “jiu-jitsu” happens in 1532 and is coined by the Takenouchi Ryu (school). The history of the art during this time is uncertain because teachers kept everything secret to give their art a feeling of importance and then would change the stories of their art to suit their own needs.
After the Feudal period in Japan ended (Jiu-jitsu was no longer needed on the battlefield), a way to practice the art realistically was needed, which is why Jigoro Kano (1860–1938), a practitioner of Jiu-Jitsu, developed his own system of Jiu-Jitsu in the late 1800’s, called Judo. Judo was helpful because it allowed practitioners the ability to try the art safely and realistically at the same time. The most important contribution Judo made to the practice of “Jiu-jitsu” was the concept of Rondori. Rondori was a form of sparing and contained a set of sportive rules that made practice safe, yet realistic. Because of the sportive outlet (rules that made practice safe), students of Jiu-jitsu from Kano’s school were able to practice more frequently due to the fact that they were not always recovering from injuries. This multiplies the amount of training time for student’s of Kano’s school and drastically increased their abilities. Judo (Kano’s version of Jiu-jitsu) was watered down from the complete form (of Jiu-jitsu), but still contained enough techniques to preserve its realistic effectiveness. The one problem that occurred was, in Kano’s opinion, ground work was not as important as achieving the throw or take down, therefore ground fighting was not emphasized in Judo and became weak in that system. Judo also began placing too many rules and regulations on the art to make it more acceptable as an Olympic sport. Leg locks were not allowed, and when a fight went to the ground, a player had only 25 seconds to escape a hold or pin before the match was lost. These are a few of the rules that hindered Judo as a realistic form of self-defense. Then why did Judo flourish and why was it so great? Even with all the rules and restrictions, the time-tested principle of “pure grappler beats pure striker,” still holds true. The fact remains that most fights, even those fights occurring between strikers with no grappling experience, end up in a clinch. You see the clinch in just about every boxing match, and hundreds of punches usually need to be thrown to end the fight with a strike, which gives the grappler plenty of opportunity to take his/her opponent to the ground, where a pure striker has no experience and is at the grappler’s mercy.
After a match-up between older styles of Jiu-jitsu and Judo at the Tokyo police headquarters, Judo was named the national martial art in Japan. It was the official art used by law enforcement in the late 1800’s, and continues to be popular to this day. During World War II, many U.S. soldiers were exposed to the art of Judo and brought it back to America with them. The first issue of Black Belt magazine here in America (1961), featured a sketch of a Judo throw and was a special Judo issue.
It wasn’t until the birth of martial arts in Hollywood that the mystique of martial arts myths were catapulted to the public eye on a large scale. Here in the U.S. especially, Bruce Lee was one of the greatest catalysts for martial arts in the world today. Bruce Lee was actually a student of Judo and did many studies on grappling while he was alive. He criticized traditional martial arts as being ineffective, but ironically spread more myths about martial arts through his movies than almost anyone in martial arts history.
Jigoro Kano was the founder of Judo, however, Judo is simply a style of Jiu-jitsu and not a separate martial art. Kano was not the first to use the name Judo, the Jiu-jitsu schools he studied at, which would be the source of much of his Judo’s techniques had used the phrase before he made it famous in the late 1800’s.
The first use of the name Judo was by Seijun Inoue IV, who applied it to his Jujitsu of Jikishin-ryu. Students of Jikishin-ryu Judo were not only expected to master its ninety-seven techniques, but to also develop into generous and gentle-mannered individuals.
Kuninori Suzuki V, the Master of Kito-ryu (Kito means to Rise and Fall) Jiu-jitsu, changed the name of Kito-kumiuchi to Kito-ryu Judo in 1714. The most important contribution that kito ryu would offer Judo was the principle of kuzushi (off-balancing), which is the key to the throwing techniques of modern Judo. Jigoro Kano studied the judo of Jikishin-ryu and Kito-ryu, and incorporated some of their concepts into his original system, which he named Kodokan Judo.
Judo is made up of many styles of Jiu-jitsu whose masters Kano had studied with. The most notable were Jikishin-ryu, Kito-ryu, and later Fusen-ryu would be incorporated for its groundwork (ne waza) as Kano would ask the style’s head master, Mataemon Tanabe for his syllabus. Yokiashi Yamashita (Kano’s Chief assistant) would add his knowledge of Yoshin Ryu ju jitsu and Tenshin shinyo Ryu ju jitsu, both of which, he was a master.
In 1912, Kano met with the remaining leader masters of Jiu Jitsu to finalize a Kodokan syllabus of training and kata. Aoyagi of Sosusihis Ryu, Takano, Yano, Kotaro Imei and Hikasuburo Ohshima from Takeuisi Ryu. Jushin Sekiguchi and Mogichi Tsumizu from Sekiguchi Ryu, Eguchi from Kyushin Ryu, Hoshino from Shiten Ryu, Inazu from Miura Ryu and finally, Takamatsu, a Kukkishin Ryu master, whose school specialized in weapons training.
Before the formal meeting between Kano and the grandmasters of Japan’s greatest Jiu-jitsu schools, a defining event occurred, which is one of the most historically important pieces of the Brazilian Jiu-jitsu puzzle. By 1900, the Kodokan had been challenging other Jiu-Jitsu schools in sport competition and winning with throwing (standing) techniques. Much of the Kodokan’s status was built on the throwing skills of Shiro Saigo, a practitioner of Oshikiuchi, the art of Daito Ryu Aikijujutsu. Jigoro Kano had actually enlisted the help of Shiro Saigo in order to win a famous tournament at the Tokyo police headquarters in 1886. This tournament, mentioned briefly earlier in this chapter, was Judo (Kano’s style of Jujitsu) vs. “old” Jujitsu. It is interesting to note that Kano’s champion was not originally a Judo student at all, but a student of an older Jujitsu style, which in reality, defeated the purpose of having a Judo vs. Jujitsu tournament in the first place.
As I stated earlier, Judo was a collection of Jiu-jitsu styles, once such style was the Fusen Ryu. Fusen was a school of Jiu-jitsu which specialized in Ground Work (Ne Waza). In 1900, the Kodokan challenged the Fusen Ryu school to a contest. At that time Judo did not have Ne Waza (ground fighting techniques), so instead they fought standing up, as Kano had been taught in both the Tenshin Shinyo Ryu and Kito Ryu systems he studied. Both Kito Ryu and Tenshin Shinyo Ryu had excellent striking skills and effective throws.
When Kodokan Judo practitioners fought the practitioners of Fusen Ryu Jiu-Jitsu, the Kodokan practitioners realized that there was no way they could defeat the Kodokan Judoka standing, thus they decided to use their superior ground fighting skills. When the Kodokan fighters and the Fusen Ryu men began to fight, the Jiu-Jitsu practitioners immediately went to the guard position ( lying on their backs in front of their opponents in order to control them with the use of their legs). The Kodokan Judoka didn’t know what to do, and then the Fusen Ryu practitioners took them to the ground, using submission holds to win the matches. This was the first real loss that the Kodokan had experienced in eight years.
Kano knew that if they were going to continue challenging other Jiu-Jitsu schools, they needed a full range of ground fighting techniques. Thus with friends of other Jiu-Jitsu systems, among them being Fusen Ryu practitioners, Kano formulated the Ne Waza (ground techniques) of Kodokan Judo which included three divisions: Katame Waza (joint locking techniques), Shime Waza (choking techniques), and Osae Waza (holding techniques). This all occurs shortly before Judo arrives in Brazil, and serves as an excellent suggestion as to why Brazilian Jiu-jitsu contains a higher percentage of techniques on the ground than most styles of Jiu-jitsu or Judo. Thus, we find ourselves faced with the impending development of Jiu-Jitsu in Brazil.
