A main component of Dai Yon is the (un)famous 7-hon no kuzushi. The 1st part of the Dai-Yon is about throwing an opponent after acquiring a perfect “kuzushi”. This possibility in a fighting situation will be very rare….although it can happen if…..
Koryu no kata Dai Yon
- Nage no kata – omote waza – 7 waza
- Nage no kata – ura waza – 7 waza
- Oyo waza* – applications – 11 waza
*Oyo waza designates applications build upon 7-hon no kuzushi basics.
Nage no kata – omote waza
The 1st part of the kata is build upon the 7-hon no kuzushi. A throwing action is added after the kuzushi.
The focus is on the action of the hand and arm doing the kuzushi. The efficiency of the throw is depending on the elasticity of Tori’s body. When the body is stretched power is stored and can be released into uke’s body.
The dynamics of the kuzushi (loss of balance) will undergo the influence of gravity.
There is a mechanism we have to take in account when we use stretching and release.
With the muscular relaxation, the movement is immediate, in a single time, this movement is much faster than with the muscular system of contraction. If we try to throw with muscular contraction, opponent will sense your intention and will block your movement.
Using meguri and tenshi-kei is necessary to create efficient kuzushi.
Jodan aigamae & Jodan gyakugamae
Kuzushi is created by using a rotational movement of the hand, followed by a body movement with the elbow as a transfer joint.
When you try to lift the hand and arm, Uke will feel and block your movement.
Jodan aigamae & gyakugamae are actions on the inside of Uke’s arm.
Chudan aigamae & Chudan gyakugamae
Kuzushi is created by using a rotational movement of the hand, followed by a body movement with the elbow as a transfer joint.
The skill is to turn opponent’s arm in hineri fashion without stretching opponent’s arm. Rotating the arm is the message.
Chudan aigamae & gyakugamae are actions on the outside of Uke’s arm.
Gedan aigamae & Gedan gyakugamae
Using downward power. No pulling action.

Keep centerline when rotating.
