Could somebody please explain the basic concepts and principles which they've learnt involving Koppojutsu. I'm aware that it involves strikes/nerve attacks/muscle tearing/pressure point attacks. I would like to know some specifics, such as which throws/kicks/punches come from this Ryu.Generally how do we learn to perform these acts efficiently, if we can't actually practice most of them per say on a living example (logically ) EDIT: After a quick search, I see this subject is slightly "taboo".Although, not much has been said about it. I've actually ordered The Daikomyosai Koppojutsu DVD though, I'm wondering what to expect. Exciting I found this interesting article which explains it's history : Kamae ****en no Kamae Hachiku no Kamae Ichimonji no Kamae Sanposhin no Kamae Hira Ichimonji no Kamae Characteristics This school is most famous in the Bujinkan for the difficult and odd Kamae's of it's taijutsu. It is specialized in Koppojutsu. Gikan Ryu has many special punches, kicks, and throws, as well as special movement techniques. Brief History The founder of this ryu was Uryu Hangan Gikanbo. The 10th Soke, Uryu Gikan, befriended Ishitani Takeoi Masatsugu, Soke of Kukishinden Ryu and Takagi Yoshin Ryu at the time. After training him in Gikan Ryu Koppojutsu, Uryu Gikan presented him with Menkyo Kaiden and made him his successor. "Bufu ni sente nashi" - 'from this side there is not the first strike' The History of Gikan Ryu Kopojutsu Gikan Ryu Koppojutsu was founded by Uryu Hangan Gikanbo (1558-1570), who was the Daimyo (feudal warlord) of Kawachi no Kuni (Kawachi Castle). It is said that Uryu Gikanbo's punch was so powerful that he once broke a sword blade in half. He was also a master of Hichojutsu and Senban Nage. The 10th Soke Uryu Gikan had been fighting in the battle now known as "Tenchigumi no Ran". This took place on the 17th August 1863. He was fighting for the emperor's army, but was shot in the arm. He still continued to fight with the use of only one arm. When he could he retired to the safety of a nearby temple. It was at this temple that he was met by Ishitani Takeoi Masatsugu, of the Kukishinden Ryu. He told Ishitani that the battle had already finished, so Ishitani then helped him to recover and afterwards escape to Iga. A friendship was then formed, and Ishitani was taught the Gikan Ryu and when he attained the required skill level, Uryu presented him with the Menkyo Kaiden, and he became the next Soke of the Gikan Ryu, adding this lineage to two others that he was already the Soke of. These being Kukishinden Ryu and Tagaki Yoshin Ryu. Takamatsu Toshitsugu orginally awarded this system to Akimoto Fumio, who became the 14th soke. Akimoto met an untimely death from an illness around 1962, and he left no successor. The system therefore came back to Takamatsu Sensei. He passed the style onto Masaaki Hatsumi, who is the current soke, as listed in the Bugei Ryu-ha Daijiten. It should be said that this Ryu has branched. That happened because Takamatsu also gave Menkyo Kaiden to Sato Kinbei in Gikan Ryu, Kukishinden Ryu and Tagaki Ryu. This man can rightly claim to be the 13th Soke of Gikan Ryu, just as Hatsumi can claim to be the 15th Soke. One of the special teachings of Gikan Ryu is "Bufu ni sente nashi" (From this side there is not the first strike). This ryu contains many special kicks, punches and throws. We have been told that the makimono scrolls do not contain step by step instructions of techniques. There are no formal kata in the Gikan ryu. The techniques are created based on the skill of the exponent, and are a combination of the body's movement and the methods of kicking and striking from the ryu. The methods are taught orally.

Mueller Last month I covered some of the differences and misconceptions between the Jutaijutsu and the Dakentaijutsu. This month I will try to clarify some points regarding the differences and similarities between Koppojutsu and Koshijutsu. To begin, many people state that the Koppojutsu and Koshijutsu are sub-divisions of the Dakentaijutsu. This is simply untrue. They are all different arts with different principles and concepts. The commonly stated differences are usually gross over-simplifications of the true differences. The typical answers to the question "What's the difference between Koppojutsu and Koshijutsu?" are: Koppojutsu is bone-breaking, and Koshijutsu is muscle and tissue tearing using the fingertips. Some people go on to describe that the Koshijutsu tearing is done to the kyusho (nerve point or vital point). Well, this is um, kind of true. Maybe. Let's take an look at the two systems on their true base levels. Let's begin with the Koshijutsu. The Gyokko Ryu Koshijutsu is based on affecting the Kyusho at 45 degree angles by using the fingertips and STRIKES. The "muscle and tissue tearing" usually spoken of is a by-product of affecting the kyusho. But it is not limited to such action. There are many kyusho that are exploited in the Gyokko Ryu Koshijutsu that don't tear tissue or muscles. The method for developing power in the Koshijutsu is a pivoting action around the spinal column, which creates a solid, snapping strike. Now let's look at the Koppojutsu. It has been simplified to the extreme, usually being summed up in two words, "Bone Breaking." Well, let's start at the beginning, the Koppojutsu comes from the Koshijutsu. The Koppojutsu deals with the use of the skeleton structure, also known as Kohtsu Po (Bone Method). The whole body method in the Koppojutsu causes the attacker to commit when attacking and thereby stretching himself out. This allows the Koppojutsu stylist to strike with the entire skeleton and body weight to throw the uke of balance with the initial contact. This creates a solid, crushing strike. It uses the principles of striking the kyusho at 45 degree angles as well as an added method of "bone-breaking." This deals with striking the kyusho at 90 degree angles to break the bone or create the feeling of numbness that accompanies a broken limb. As an interesting aside, the kyusho names used in the Bujinkan today come from the Koto Ryu Koppojutsu. Let's sum up. The Koshijutsu involves the striking and grabbing of kyusho at 45 degree angles. The power of these strikes comes from the rotation of the body and is generated by the limbs. The Koppojutsu involves striking the kyusho at 45 and 90 degree angles using the entire skeleton as the tool. They both involve striking the same kyusho, use the same method of 45 degree angle striking and grabbing. The difference is in where the power comes from and the added method of "bone-breaking" in the Koppojutsu. Now these are the differences as they apply to the Gyokko Ryu Koshijutsu and the Koto Ryu Koppojutsu and to any other system of Koshijutsu or Koppojutsu. And please remember that this article was written on the base level of understanding that students should have concerning these two integral concepts of the Bujinkan. There are many other differences, concerning throws, joint-locks, etc.... I hope this once again clears up any over-simplification of these important terms. GIKAN RYU KOPPOJUTSU SHODEN NO KURAI 1.

San Myaku Dori #4 Iri Chigae The attacker grabs your right wrist with his right hand. You step back left and grab the inside of the wrist, then step in (lowering your stance) and strike with a left happoken fist to the solar plexus, barring the arm. Bring the wrist down to your belt, then take a deep step away and twist to throw the attacker to the ground. #6 Ryote Dori The attacker grabs both wrists. Step forward to the right at a 45 degree angle, taking your left hand towards the eyes to break the grip. Push your left hand in one smooth motion past the attacker's left shoulder, then bring down your left elbow sharply onto the attacker's left elbow to break it while stepping back and sinking. #8 Kasumi Gaeshi The attacker grabs the left lapel with his right hand and punch to the face with his left. Cover the grabbing hand with your left hand. Avoid the punch by stepping to the left while bringing your right hand over the top to grab your own clothing, entangling the attacker's hand. Then twist to the right, taking ura gyaku, bringing your left elbow over the top of the grabbing arm to lock it. Twist back to break the arm.
