Kuzushi-no-kata

This is an early kata devised by Tomiki sensei.  The emphasis is on 
clean lines of off-balance, the eight directions (happo no kuzushi).
I nicknamed this the "rice grain kata" because it was demonstrated
with tape on the mat marking a plus sign with four half-length strips 
on the diagonals, resembling the kanji for rice grain ("KOME").


1.  Iriminage

Uke strikes right hand at tori's right temple (outside yokomen uchi).
Tori makes kuzushi with right hand (aigamae), striking with tegatana
to 45 degrees left (uke's front right) along the line of the attack, and 
moves behind uke's arm to enter into iriminage.  Uke reacts 180 degrees 
(the opposite diagonal).

Variation 1A:  Tori grasps the collar and drops his elbow in between 
               uke's shoulder blades.  Uke takes backfall.  
Variation 1B:  Uke turns and takes a forward roll.
Variation 1C:  Uke turns, tori takes uke across hip and throws koshi nage.


2.  Kotegaeshi

Uke strikes right hand at tori's right temple (outside yokomen uchi).
Tori makes kuzushi with left hand (gyakugamae), striking with tegatana
to 45 degrees right (uke's front left).  Uke reacts 180 degrees, but tori 
takes uke's wrist and throws kotegaeshi to 90 degrees. 

Variation 2A:  Uke takes forward airfall on the body drop.
Variation 2B:  Throw on the rise as uke's wrist comes up into tori's grasp.


3.  Ushiro-ate

Uke strikes right hand at tori's left temple (inside yokomen uchi).
Tori makes kuzushi with right hand (aigamae), striking with tegatana
to 45 degrees left and scooping the arm to uke's front left as in 2nd 
release as uke recovers.  Tori passes outside and rolls into ushiro-ate.

Variation 3A:  Tori passes under arms and wraps the chest.  Backfall.
Variation 3B:  Tori keeps hand above uke's arms and hooks the shoulders.
Variation 3C:  Tori goes under arms but raises right arm as in katagatame,
               and throws iriminage.  This is another alternative to 
               protect against an elbow strike in the original version.


4.  Sumiotoshi

Uke strikes right hand at tori's left temple (inside yokomen uchi).
Tori makes kuzushi with left hand (gyakugamae), preempting the attack and 
striking with tegatana or forearm 45 degrees front left (uke's rear right)
corner.

Variation 4A:  One-handed sumiotoshi backfall.
Variation 4B:  Secondary shomen-ate hand, keeping left step sumiotoshi.
Variation 4C:  Intercept attack early & high, step under and take down
               with hikitaoshi to uke's rear right corner.
