Judo Self-Defense Forms: Goshin Jutsu

Kodokan Goshin Jutsu

The Kodokan Goshin Jutsu was created in 1956 by a Kodokan working group to update the older kata with more modern forms of self-defense. It also shows the influence of Kenji Tomiki, one of Professor Kano's students, who also studied Aikido under the founder of Aikido.

It consists of 21 techniques against an unarmed, as well as armed, attacker. It is divided into two unarmed sets (toshu no bu) and three sets with weapons (buki no bu). The first seven techniques are against an attack close in. The next five are against attacks from strikes and kicks. Then there are three attacks with a knife, three with a stick and three with a gun. The techniques here cannot be used in free exercise practice or in competition, but only in kata. Never-the-less, as one practices this kata, the attack speed increases and one's reflexes and reactions sharpen to meet the attack. Eventually, this kata can be practiced with real weapons.

The intent in this kata is different than with normal Judo practice, in that this is a self-defense kata, the intent on the part of both participants is to hurt the other. While the actions are controlled, so that the attacker is not hurt, the defender's actions can easily be modified to disable the attacker. It is important to realize that all of the techniques in this kata are consistant with the principles of "Judo", the way of gentleness or yielding.

For complete videos of the Kodokan Goshin Jutsu see the demonstration by the First Place Winners from Japan at the 2008 IJF Kata World Cup, or this one by the US Finalists. Additional videos from the Kodokan are at the bottom of this page following the description.

Unarmed Close-in Attacks by Holding

 

Ryote dori - two hand hold Ryote Dori

Stepping forward with the left foot, the attacker grabs both wrists and attempts a right knee kick to the groin. Defender avoids the kick by stepping back with the left foot, forces his right hand against attacker's weak thumb releasing the grip, and continues his motion into a right knife edge strike to the temple. Defender then uses the right hand to grab the attacker's right wrist from the top and twists to the right, and ends with an armlock and wrist lock forcing the attacker to submit or have his arm broken.

He immediately grabs the attacker's right wrist from the top with his right hand, placing his left hand on the attacker's right elbow and stepping back with the right foot. He ends the attack by forcing the attacker to the ground with a wrist and elbow joint lock, controlling his body with his left knee.

 

Migi eri dori - right lapel hold Migi eri dori

As attacker grabs across to the right lapel and pulls defender forward by stepping back with his left foot, defender steps forward with the right foot and delivers a right uppercut to the chin of the attacker. He then grabs the wrist with the left hand from the top, steps back with the left foot, adds the right hand, and turns forcing the attacker to be thrown with the wrist lock.

 

Kata ude dori - single hand holdKata ude dori

Ushiro jime - rear chokeUshiro Jime

Attacker puts his right arm around the defender's neck from the rear to apply hadaka jime. Defender tucks in his chin and pulls the arm down from his throat. He then steps forward with the right foot, turns to the left ducking under the choke, forcing attacker's arm into the te gatame armlock with his right hand on the attacker's elbow and left hand grasping the wrist.

 

Kakae dori - rear seizureKakae Dori

Attacker steps forward with his right foot and grasps the body and arms from behind as in a bear hug. Defender counters by raising shoulders and arms and simultaneously stomping on attacker's foot with a forceful downward kick. This causes attacker to release grip. Defender then turns to the right to grab the right wrist with his left hand, bringing the right arm up behind the elbow pushing attacker's arm into a forceful throw which is applied by continuing the turning motion.

 

Unarmed Attack at a Distance

Naname uchi - slanting strikeNaname uchi

Advancing with his right foot attacker attempts to strike the left side of defender's head with his right hand. Strike is parried by stepping outside attacker's right foot with the left and turning to the right pushing the arm down as it misses it's target. It is countered with a right uppercut to the chin and a throat grab forcing attacker off balance backwards as defender applies right osotogari to the attacker's rear.

 

Ago tsuki - uppercutAgo tsuki

Attacker attempts a right uppercut that is parried by defender as he steps back with his left foot. Attacker's arm motion is redirected by grabbing the wrist with the blocking right hand.

Gammen tsuki - thrust punch or jabGammen tsuki

Attacker steps forward with his left foot and punches the face with the left fist.

Yoko geri - side kickYoko geri

Walking towards each other, attacker attempts a side kick as he passes defender, who parries the kick, turns and pulls attacker down onto his back dropping onto his left knee. While this technique in the kata looks harmless enough, in actuality, the defender would leave his right knee in place behind the attacker so that he falls with his lower back on the knee, which would no doubt break the attacker's back.
