Jiin is not seen very often in tournaments, and for this reason practice of it is becoming more and more scarce. It is not very pretty, according to some, and its plodding and redundant enbusen does not help anyone to wish to learn it. 

Jiin does not start and end on the same spot on the floor. No matter how the kata is toyed with, or what angles the stances are performed at, the kata will not come back to the same spot. There are two possible ways to solve the problem of Jiin not finishing where it began. One solution is to finish the kata by pulling in the left leg, a movement which is generally forbidden at the end of all Shotokan kata. Another solution is to simply accept that the kata, like many older kata, does not end on the same spot. Finishing the kata in a different spot may seem like a radical concept to the typical Shotokan enthusiast, but it is not a new concept.

Originally Heian Yondan was intended to end behind the starting point, and Heian Godan in front of it so that the starting place was retained. Most of the kata which start and finish on the same spot were modified after World War II to do so. Therefore, many instructors in the West can only complete some kata on the starting point, while others continually finish 6 inches to three feet away from the starting position.

1.        Hand Over Fist and with both feet touching from ball to heel with the toes forward. The knees should be straight. The left hand should be over the right fist. The elbows should be at the sides of the body, and the tallest knuckle on the left hand should be directly in front of the chin. Do not bend the wrists and point the elbows out sideways. Instead, keep the elbows in pretty close to the sides of the body and the wrists straight.

2.        Step backward with the left foot so that it becomes the rear foot of a right front stance. At the same time, unfold the hands from their positioning and down block with the right hand as you inside block with the left hand. These arm actions are not preceded by folding or crossing of the arms; simply burst them into place.

3.        Double blocks - Step out with the left foot to the left side so that it becomes the front foot in a back stance. Do these blocks simultaneously from a folded position. In the folded position, both hands are in knife hand postures and the right hand is palm up and reaching downward. The left hand is palm inward and beside the right ear. The folding action is a snapping technique. Downward block with the left arm and inside block to the upper level with the right arm. Shift your body weight over the other leg, pivot on the heels, and rotate to face the opposite direction in another back stance. Reverse the blocks after folding the hands as above.

4.        Upper Block Stepping Punch - Turn 135° (45° to the front wall), and left side upper block in front stance. Do this by reaching with the right open hand over your forehead, and then throwing an upper level rising block with the left hand as you rotate the hips to the side. Step forward middle level punch with the right hand. Pivot on the left foot and move the right foot across 90° to the other side and upper block with the right arm in the mirror image of what you just did above. Step in and punch middle level.

5.        Down Block - Turn to the left facing toward the front again and down block with the left arm in a front stance.

6.        Knife Hand Strikes - Step forward into a side-facing horse riding stance with the right foot as the front foot. Raise the right hand as you begin the step as if you were going to throw an outside block, but keep the hand open. As the feet pass each other, right side outside knife hand strike to either the throat or the stomach.

7.        Step forward again and repeat the strike. Step forwards a third time and kiai.

8.        Wedge Block - Pivot on the right foot counter clockwise drawing the left foot up to the right, turning, and then stepping out to the left flank 45 degree angle with the left foot so that you are in another front stance. As you move the foot forward and touch it to the floor, decelerate considerably so that your weight settles into the stance gently. Bring the fists up in front of your eyes about one foot away during the step while you are in a sort of cat stance during the midway point. The palm sides should be facing inward, and the arms should be crossed at the wrists. Turn the wrists as you pull your elbows down to your sides to perform a wedge block. The action of bringing the hands up should be extremely fast, in time with the first part of the stepping motion. Parting the arms and performing the block should start with a very small burst of speed, and then lose speed and gain tension as you move.

9.        Kicking and Punching - Keeping your arms in the same position relative to your body, step forward and throw a right front snap kick to the middle level.

10.     Double Punch - Throw two punches from your current position. Your hips should stay square to the front facing position. The first punch should be fast and snapped, the second punch is strong and thrusted.

11.     Double blocks - Stay in position and fold the arms across so that the left fist is by the right ear, the right fist is on the left waist, and the elbows are very close together. Unfold them with a burst into a right inside block and a left down block.

12.     Repeat - Perform the mirror image of that 5 technique sequence on the right side. Pivot on the left foot so that your right foot becomes the front foot of a new front stance 90 degrees to the right. Wedge block as before, kick, throw the two punches, and then throw the cross block you did before, this time with the left arm in the inside block and the right arm in the down block.

13.     Stepping Bottom Fist Strikes - From this position, you will step with the right foot and pivot on the left foot in a clockwise rotation so that you spin backwards most of the way around a circle. Finish in a horse riding stance and throw a bottom fist strike to your own shoulder height.

Step and spin again, this time in a counter-clockwise rotation and finish in the same stance with the left leg forward and bottom fist strike with the left fist.

Step without spinning this time so that the right leg becomes the front leg in yet a third side-facing horse riding stance. Strike with a bottom fist strike again (or is it a punch?).

14.     Vertical Knife Hand Block - Step forward to a 45 degree angle to the left into a front stance. (This could also be in an unmovable stance; the choice is yours). Decelerate and add tension to your left hand vertical knife hand block as you finish the step. Rotate the hips to the side if you are using a front stance.

15.     Combo Attack - Now, rotate the hips strongly to the front so that you end up in a front-facing front stance and reverse punch. Snap this punch quickly and flow it into the next punch with the left hand. In place, without stepping forward, front snap kick to either the high or the low level with the right leg. Replace the leg on the floor back where it came from. Now punch again with the right hand.

Now perform the cross block once again. Fold the arms and burst them apart so that the left arm is in an inside block and the right ends in a down block. You should still be in a left leg forward front stance at this point.

16.     Cross Block - Swing the left foot around counter-clockwise pivoting on the right foot until you are facing front again in a new horse riding stance. As you turn, fold the arms and perform another cross block in the opposite positions from the last technique: the right arm is doing an inside block while the left performs a down block

17.     Down Block - Without moving any of your other body parts, flip the right hand down into a down block as well. Do this very quickly.

18.     Double Inside Blocks - Slowly bring both hands up across the stomach and outward, decelerating and adding tension, as you perform an inside block with both hands simultaneously.

19.     Double Punch - In the horse riding stance, without any stepping or shifting, punch directly from this position with the left hand to the high level. Flow into a middle level punch performed by the right hand. The first one is snapped, the second one is thrusted. Kiai on that second punch.

20.     Finish - Stand back up into the hand over fist posture with the feet together (left foot to right).
