Tukauchi or Kojirigaeshi, followed by transitioning into Iaigoshi (a low kneeling posture), are then executed with a large backward retreat—over six shaku (approximately 180 cm)—into the Shumokuashi stance.
This time, we will explain an innovative refinement to address this challenge.
From this point, you simply step back, but you must retreat as far as possible. It is said to be more than 180 centimeters.
In this way, after executing the technique, you retreat deeply to create as much distance as possible from the opponent.
However, most people are unable to retreat that far. This is because the majority are using incorrect body mechanics when stepping back.
Ordinarily, one would think to pull the rear foot straight back like this.
However, in practice, when you pull the rear foot directly back, your movement energy is spent at that point, and the backward motion quickly comes to a stop.
In practice, when you slightly raise your hips in place, you should first imagine bringing the rear foot—or the rear knee—even closer to the front foot, as if drawing the back side of the pelvis forward. Only then do you begin the backward movement.
By slightly moving the rear foot or rear knee forward—essentially sliding the pelvis forward—you bring the body’s center of gravity toward the center, or even slightly forward.
By doing so, the center of gravity naturally converges at a single point, allowing you to retreat a great distance in one swift motion.
However, if this slight preparatory movement is not performed, the center of gravity is dispersed from the beginning, causing a loss of momentum at the start of the movement and resulting in a shorter retreat distance.
Before moving the foot backward, imagine shifting the rear foot or rear knee forward in an exaggerated way, transferring your weight onto one leg as if standing on a single foot. By concentrating your center of gravity this way, you’ll find it much easier to move in a large, clear motion.
Of course, in actual practice, this is done in an instant and functions as a subtle preparatory movement that does not hinder the echnique.
With this method, anyone should be able to retreat the required distance.
As a basic standard, aim to retreat roughly the length of your own height.
(For those under 170 cm tall, a full 180 cm retreat may not be realistic.)
