Kaishakunin - The Ritual

The Ritual

Still preserved in modern-day movements (kata) of the martial art, Iaido, the ritual of performing kaishaku varies very little between Japanese fencing schools, but all of them are bound to the following steps to be performed by the kaishakunin:

1. First, the kaishakunin sits down in the upright (seiza) position, or remains standing, at the left side of the person about to commit seppuku, at a prudent distance but close enough to be reached with his sword (katana) at the appropriate time.
2. If seated, the kaishakunin will rise slowly, first on his knees, then stepping with the right foot while drawing the katana very slowly and silently and standing up in the same fashion (keeping in mind that the opponent (teki) is not an enemy, but rather a fellow samurai). If the kaishakunin was from a standing stance, he will draw his sword slowly and silently as well. In both cases, after the sword is out of the scabbard (saya), he will raise it with the right hand and wait for the seppuku to begin. Some classic (koryū) Iaido styles, like the Musō Jikiden Eishin-ryū school, establishes this "waiting stance" as the kaishakunin having taken one step back with the right foot, katana behind his head parallel to the floor held with the right hand, left hand holding the scabbard in the proper (sayabiki) position; other styles, like Musō Shinden-ryū, establishes that the katana is to be held vertically, parallel to the body, held in the right hand, the left hand resting at the kaishakunin side, feet together. In any case, the kaishakunin will always keep eye contact with the samurai performing seppuku, and waiting for his cut (kiri) through his abdomen (hara).
3. When the samurai actually performs the seppuku, and after he returns the dagger (tantō) blade back to the cut beginning, the kaishakunin steps forward, letting the katana drop straight through the back of the neck of the dying samurai. Just before making contact, the kaishakunin grips the handle (tsuka) with both hands, giving precision to the katana's blade and strength to the downward cut (kiritsuke). Only the samurai that were invited to perform seppuku in order to preserve their honor were allowed to have a kaishakunin to assist. Samurai committing seppuku for criminal actions were not allowed an assistant. The final cut has to be controlled in order for the initial cut to reach only half the neck of the samurai; the final cut, leaving the required skin to hold the head attached to the samurai's body, was performed by a single slashing/withdrawing motion of the katana. The complete cut-slash-withdraw motion is called daki-kubi.

After the dead samurai falls, the kaishakunin, with the same slow, silent style used when unsheathing the katana, shakes the blood off the blade (a movement called chiburi) and returns the katana to the scabbard (a movement called noto), while kneeling towards the fellow samurai's dead body. When this is completed, the kaishakunin remains kneeling for a while, as a sign of deep respect to the fallen samurai who committed the ritual suicide, always in a state of "total awareness" (zanshin) before standing up and bowing (rei) to his body.
