Otsuka Sensei performing Tobikomizuki.
Without a doubt nagashizuki is a hallmark technique of Wado karate; it is also one of the most difficult to teach.
In other styles of karate I have only ever seen techniques that hint at an application that could loosely fall into the area of nagashizuki, with a very rudimentary nod towards something that could be categorised as Taisabaki, but at risk of contradiction nagashizuki in karate is pretty much unique to Wado.
But there is so much to say about nagashizuki as it features in the Wado curriculum as it helps to define what we do.
If you were to explain nagashizuki to another martial artist who has no knowledge of Wado, you could describe it as being very much characteristic of Wado as a style; a technique pared to the bone, without any frills or extra movements. Done properly it is like being on the knife-edge, it is brinksmanship taken to the extreme. I have heard a much used phrase that to my mind gives a picture of the character of nagashizuki, as follows:
‘If he cuts my cloth I cut his skin. If he cuts my skin I cut his bone’.*
Here is a technique that flirts with danger and requires a single-minded, razor sharp commitment, with serious consequences at stake.
Technically, there are so many things that can go wrong with this technique at so many levels. In an active scenario you have to have supreme courage to plunge directly into the line of fire, the timing is devastating if you get it right. Many years ago it was my go-to technique when fighting people outside of Wado, particularly those who took an aggressive line of attack hoping to drive forward and keep you in defensive mode. But I also found out that this technique had added extras, which you must be aware of if you use it in fighting; one of which is the devastating effect of the strike angle.
On two occasions I can think of, to my shame, I knocked opponents unconscious with nagashizuki. When delivered at jodan level the strike comes in from low down, almost underneath the opponent and its angle is such that it will connect with the underneath and side of the jaw. As I found out, it doesn’t need much force to deliver a shockwave to the brain, and, if the opponent is storming in, they supply a significant amount of the impact themselves – they run onto it.
This last point about forward momentum and clashing forces illustrates one of the oddities of the way the energy is delivered through the arm. A standing punch generally has to have some form of preparatory action (chambering), depending where it is coming from; nagashizuki when taught in kihon is deliberately delivered from a ‘natural’ position, and as such the arms should just lift as directly and naturally as possible into the fulling extended punch – my favoured teaching phrase for that is, ‘like raising your arm to put on a light switch’, that’s it. The arm itself acts as a conduit for a relay of connected energy generators that channel through the skeletal and muscular system into and beyond the point of delivery.
This is where further things can go wrong; the energy can be hijacked by an over-emphasis on the arm muscles or the ‘Intent’ to punch. Don’t get me wrong, ‘Intent’ can be a good thing, but when it dominates your technique to such a degree that it becomes a hindrance this can cause all kinds of problems.
The building blocks to nagashizuki could be said to begin with junzuki, then on to junzuki-no-tsukomi and then to tobikomizuki and finally to nagashizuki. Lessons learned properly at each of those stages gives you all the information you need, but it is important to go back to those earlier lessons as well. Junzuki-no-tsukomi for its structure is the template for your nagashizuki, but not just for its static position, but how it is delivered through motion; it is an amplified version of things you learned in junzuki – it is junzuki with the volume turned up.
Nagashizuki is a good technique to pressure-test; from a straight punch (at any level) to a maegeri, even to a descending bokken; this is very useful because it emphasises the slipping/yielding side of the technique; a very determined extension of one half of the body is augmented by a very sharpened retraction of the other half, the movements feed off each other, but essentially they are One. In fact everything is One, in that wonderful Wado way. And here is the conundrum that we all have to face when doing Wado technique; you always have a huge agenda of items that make up one single technique BUT…. They all have to be done AS ONE.
