I have spoken before about the generational shift that occurs in systems over time. Generational shift happens when an original idea gradually transitions into a form that is accessible to more people. In the effort to spread it, the idea slowly becomes something that it was not.

This effect can be subtle, but one place where it is worn on its sleeve is in the rules around practices and sparring. One example of this is tournament rulesets, which often include detailed sections on what is allowed and what is illegal. Gamesmanship inevitably occurs, and winners are sometimes those who best exploit the rules rather than those who demonstrate competence in a real encounter.

Another place where this shift can be seen is in the very drills and practices that a group uses to build efficacy. A repetitive drill done without intent or focus—or performed with minimal repetitions—is not the same thing as a drill performed with its full, deadly intent.

Sometimes a transformation toward a milder form is simply a matter of age. I am no longer drawn to the intensity that forged me in my youth. Instead, I take a broader and calmer view that, having passed through that crucible of fire, now feels more stable and perhaps even more powerful. It is like comparing a raging fire to the ocean.

Certainly, not all practices need to exist on the edge of life and death. Soft energy, slow motion, and play are all valid. The trick is to avoid delusion.

Ippon Kumite (One Attack)

It is another Sunday morning and I am meeting with my karate comrades again. Today the practice is being run by Kurt. I knew Kurt when he was a young man, and we have been periodically connected over the years. He was my partner—my uke—for a demonstration of throwing techniques at my yodan test, my fourth-level exam. This morning he is in charge. This is wonderful to see and reflect on. The juniors rise to the level of their teachers over time.

Our practice began with a warm-up and then some drills of oi-zuki (a front punch using a passing step). Al (Kurt’s father) and I, the seniors of the day, moved alongside them for a time and then stepped back to watch.

There is so much to see in the movements of others. Certainty waxes and wanes, as do confidence and clarity. Watching others provokes me to think as an instructor. In my mind I analyze and consider what I would say, but this practice is Kurt’s. It is important not to intervene. A good teacher needs fullness, and grumpy old men can steal that fullness even with otherwise good intentions. So we watch from the sidelines, content to witness the learning unfold along the long path.

I think of footwork and how placement of the feet can liberate or bind a person. I see weight distribution as either an anchor or a release. Tight shoulders will teach the young ones better than my words over time. I still cannot resist, I confess, the occasional thought leaking out, followed by a shrug and an admission of my own foibles.

Kurt’s intention on this day was to prepare the students for a grading that was coming up. After the oi-zuki practice he focused on one attack.

One attack (ippon kumite) is a form of designated sparring. It emerged from several converging influences:

Okinawan paired training drills

Japanese budō pedagogy, especially from kendo and judo, such as yakusoku keiko—prearranged attack practice

Ippon kumite may or may not have been copied directly from kendo, but the training philosophy behind it was strongly shaped by the same budō culture that produced kendo training methods.

The Shotokan attempt to create a structured progression toward free sparring appeared largely through the work of Funakoshi’s son, Yoshitaka Funakoshi, along with other early Shotokan instructors.

They introduced structured kumite stages:

• gohon kumite (five attacks)
• sanbon kumite (three attacks)
• ippon kumite (one attack)
• jiyu kumite (free sparring)

I do not know exactly how these practices were conducted in the earliest days. Many karate schools still use some form of these drills. “Five attack” is rarely seen now. “Three attack” and “one attack” are more common, but they are often presented as paired drills where everything is prearranged and the result resembles a choreography of a fight.

In my own training these practices felt more like genuine sparring. The forms we used included:

• One attack
• Three attack
• Free one attack
• Iai (close quarters sparring)
• Long-distance kumite
• Slow-motion sparring
• Free sparring

Sometimes people become mired in the protocols. In any orchestrated practice, habits can develop that do not translate well outside that environment.

That is why the various forms of designated sparring exist, each with different constraints. What is unrealistic in one drill is managed in another so that other aspects of a fight can be studied.

For example:

Free one attack allows more realistic mobility and footwork

One attack begins from a static start but allows real attacks.

Free sparring allows free timing and technique, but full-contact strikes are prohibited.

Each of these methods is an attempt to understand the realities of a fight.

One attack, for all of its earthiness, is not a stand-alone practice. If all you ever practiced was one attack, your understanding of fighting would have serious gaps. No single drill can contain the whole truth of combat.

The same problem can occur when martial artists train only within their own group. One of the most valuable experiences for a karate practitioner is to spar with a boxer. Boxing is extraordinarily refined in its development of evasive lateral footwork, timing, and powerful punching mechanics—skills that often feel less familiar to karate practitioners.

More broadly, when martial artists lose sight of the wider world and retreat into a closed system of practice, the art slowly drifts away from its original intent. Habits replace reality, choreography replaces uncertainty, and the sharp edge of the practice becomes dull.

Simplicity

These days I grow weary of seemingly endless discussions about rulesets and practice approaches in the martial world—arguments over what is the best way to do this or that. My response is often to turn away from these large intellectual debates.

That is why I like one attack. One attack eliminates many complications. It creates clarity.

The ruleset for one attack is simple. There is a designated attack. It can be anything, but it is one attack only. In my training it was often oi-zuki—a stepping punch much like a passing attack in swordplay. In swordplay the attack can be a strike or a thrust.

In our day as young men and women, this attack was delivered with serious intent to hit.

Let me emphasize that point. In the early days, when facing someone at your level or higher, the intent was genuinely to strike them with a serious punch. When facing a junior or someone you could clearly defeat, the attack would be more controlled until they developed the ability to receive serious attacks from seniors.

The defender knew what was coming, and this was their unrealistic advantage. The attacker therefore had to overcome that advantage in order to actually strike their opponent. Their practice was to perfect their attack.

The defender could evade the attack in any way they chose, but they were required to counter such that the evasion and counter occurred as one technique and one breath. If the evasion and counter occurred in two beats, it was considered ineffective.

A defender could:

block and counter much like a parry–riposte

interrupt the attack with an attack of their own

evade until the attack began to dissipate and then counter

There were many possible paths for the defender.

The only restriction placed on the defender was that the counter had to be controlled. This might seem unfair at first, but remember that the defender knew exactly what attack was coming, while the attacker was limited to a single attempt. If the defender evaded well, the attacker was left extremely vulnerable.

So one attack is an experimental lab. The attacker studies how to make a technique that is effective even when the opponent knows it’s coming. The defender studies the most efficient responses to that attack.

The Mind

This practice forces people to confront the psychological dilemmas of training even as they develop technical skill.

You could be knocked out.

You might also hit someone else.

How do you deal with those psychological dilemmas?

Fear arises. Some people struggle to follow through with intentionally trying to hurt another person. Others, after achieving some success, must learn to control their power when facing those less capable than themselves. Some become inexplicably angry and must learn to master that wildness sitting on their shoulders.

Of course, people still think about the rules as though this were a contest and fairness matters, when nothing is fair about the thing we are actually training for.

“What if I move and the attacker tracks me—is that allowed?”

Answer: Don’t move too soon or in predictable ways. Learn.

“Can I stop the attack with an attack?”

Answer: Yes—but you had better be good at it. And remember, you must control your counter.

“If I face weaker or smaller people, can I hit them hard?”

That is a more complicated question. What if I did that to you? The goal is to bring people up so they can face a real attack. If you can clearly destroy your opponent and do so relentlessly, then you are violating the code of honor that requires kindness and humility even as you test them.

And remember—your seniors believe in reciprocity.

So you might want to think twice about that.

Stripping Away Illusions

When we practiced this form of sparring with our peers and seniors, our masks and delusions were stripped away by the blunt honesty of the drill.

Can you get away from this attack?

Yes or no.

It felt honest and grounding. I always knew exactly what I needed to work on.

You know what is coming. You know what you must do.

Can you deal with it—or not?
