Today’s post is regarding recent kenjutsu training done by Chikushin group. It is more of a reiteration of verbal explanations given to students during those sessions. I also express it here for the public to get an idea of how Chikushin group conducts kobudō training.
In our kenjutsu training we’ve been studying a set of kata that focuses on defeating a stronger opponent. Within this are a few kata that uses the scenario where the both you and the opponent are in tsuba zeri-ai (鍔競り合い), which means locking swords together by the swordguard. While dependant on the martial system and their philosophy, this can be a common occurance between two sword duelists where both sides close the distance and are trying to overpower the other. Similarly, this can be seen in today’s kendō.

When looking at these particular kata as presented in our group, they present a scenario where the defender must use specific techniques to defeat their opponent who uses tsuba zeri-ai. However, before learning these, we must spend time understanding how to properly apply tsuba zeri-ai and win with it.
In kata geiko (形稽古, practicing pre-set forms), the one who’s applying the technique as the defender may be viewed as doing the “true” style of one’s kenjutsu, while the attacker is not. This is actually not correct. In fact, we have to also study what is being done by the attacker, as it is very critical for the defender’s technique to work. In the case of tsuba zeri-ai, we initially study the finer details of this technique, from how it can occur when two fighters’ swords clash together, to how to properly initiate it ourselves. It is necessary to apply proper timing, leverage, and power in order to overwhelm another through this. In the end, tsuba zeri-ai becomes a tool in our arsenal, furthering our skill level. This is the ura (裏), or unspoken rules, in studying classical martial arts.
There are plenty of unspoken rules not only in kata geiko, but in many of the components found in classical martial arts. It is just more apparent when training in set forms during katageiko as-is, for if we only focus on what the defender is doing, we will only get a small piece of the puzzle. On top of this, one cannot properly defend against an attack that is not there. It is up to the instructor to ensure that students learn the ins & outs of every kata properly. This includes performing a real technique by the attacker role.
Again, in the case of tsuba zeri-ai, if the attacker doesn’t understand how to apply his/her technique correctly in order to lock swords together, the defender won’t be able to feel the pressure necessary in learning the proper rhythm to counter the opponent. It is the same as blocking a simple punch; if we don’t engage in repetitive drills ahead of time regarding how to deliver a punch with proper power, speed, and from an adequate distance, kata that involve defense against this won’t work.
To get an idea of how tsuba zeri-ai is applied in motion, check out our Chikushin Arts Instagram account. There, you’ll find the exact video posted recently from which the pics above were taken from, along with the complete outcome of the scenario that was demonstrated. On top of that, you’ll also find other kobudō-related pics and videos posted regularly to keep our Instagram account active.
