katate HACH NO KEN JI gaeshi

suburi One of the most significant is undoubtedly dell'Aikijo katate Hachi No Ji gaeshi.

katate = hand (literally "hand shape")
eight
Hachi Ji = = = cross
gaeshi response reversal (the situation), controtecnica

Therefore, the translation is " Reply (an attack) with cross-eight motion with his hand ".

One of the most taken for this movement is a response to Renzoku Uchikomi with jo,

Go or no suburi, yokomen consecutive right-left with the bokken.

A clear application of Hachi no ji gaeshi you see in the 10th kumi jo

The reference in that it uses to run suburi this is the number eight, Hachi in Japanese

hachi

From the image you can see the "lines" which resulted in the name of the movement suburi concerned.

As you can see there are different types of styles for rappresentale Hachi. From the most narrow and rigid, and expanded to more harmonious. The writing is very personal, but the movements are.

Aikido is full of symbolism, but the symbols are codes, but should not be taken literally interpreted, most of the time analyzing the hidden meaning. And above all, must have an objective verification of the application in the real

When the wise points at the moon

the fool looks at the finger.

(Zen saying)

goes without saying that the kanji for the number eight does not want to (only) to identify the directions that the jo should go, but (also) the two main points of emphasis of the movement, that is where we will be the impact with the other jo or bokken.

During a slash of the sword (yokomen uchi) we can identify three main points of impact between jo and ken-dependent trajectories of jo 3:

let's see one by one :

A

By Kanji reference to the type A, very closed, the impact on the section of bokken would be at the top (A). Hitting on this point from above give even greater boost to blow that it will continue its downward trajectory with greater force, with the possibility to be addressed toward the body, hitting the legs.

B

Kanji With reference to the type B, more open, the impact would be on the section of bokken diagonally from top to bottom, it diverts the bokken but not to such an extent as to make sure that you do not shoot down on us, if you hit the bokken a bit 'more above its trajectory will not change.

C

Kanji With reference to the type C, very open, the impact on the section of the bokken is the most effective and deflect from the path to safer, even if the impact happen in the highest part of the bokken.

Another curiosity about number eight on its meaning "hidden", the Kanji Hachi, which in Chinese is Ba, depicts a river that divides a two branches, the origin of the sign is hence separation. The number eight, for the Chinese, was also a kind of calculation units, covered the rice field. Rice fields were divided into four parts, eight had two fields. The farmers therefore used the number eight as the basis for the division of the fields in the negotiations.

tian ("field" in Chinese)

This consideration may have to Hachi No Ji gaeshi also means to divide, move, separate.

Master De Compadre insisted on this very special to dismiss asserting that, incidentally, extraordinarily, the directional lines of relevant suburi West also looked like the number 8, reverse, and that is the symbol of infinity, an extension to the right and then left.

At this point is, in slow motion, this suburi performed by Saito Sensei and look at what is the line drawn from the jth, especially at the beginning of the movement, is almost parallel to the ground, and do not pass close to the body.

and into that sequence Miles Kessler where the open and even more pronounced:

3rd example

Contrary to the following video where jo passes close to the body of the practitioner:

5 th example

The interpretations and systems for the execution of Hachi no Ji gaeshi of these teachers are different, as is the case generally also for many other techniques of Aikido.

I suburi performed by Saito Sensei and Miles Kessler, in my opinion, are effective in practice as well as representation "philosophy" of Kanji hachi. The fourth and fifth example can also be one of the Kanji above (that of type A), but I have serious doubts and concerns about their successful implementation.
