You Don’t Need Brute Strength or Blazing Speed — Here’s Why

“Kuzushi” — the wrestling and grappling term for breaking an opponent’s balance and structure — gets used constantly on the mat. But ask someone to actually define it, and most people pause.

I recently had the chance to sit down online with Ryoma Anraku, a current top-level grappler and former wrestler. I’m in the middle of writing a book that reads wrestling through both science and the lived experience of the mat, and kuzushi sits at the center of it.

During our conversation, Anraku put it this way:

“It’s more that I liked making the other guy commit an error — that’s the feeling behind it. How do you get someone to make an error? I think that question is basically where kuzushi comes from.”

That single line holds the whole idea. Kuzushi is the skill of getting your opponent to move incorrectly. You don’t need to overpower them or outrun them — if they react on their own, you can use that reaction to score.

Anraku went further:

“I’m not someone with especially fast reflexes. That’s exactly why I paid so much attention to my stance and where I placed my hands.”

If you can’t win on speed, move your opponent before they move you. That’s not a talent — it’s a mindset, backed by deliberate adjustments. Hearing that from a top-level competitor was the first thing that struck me.

“Your Hands Are Sensors” — Withholding the Reaction

So how do you actually make an opponent commit an error? The hands are the key.

In the book, I describe the hands as sensors. They’re not only tools for controlling an opponent — they’re also the organ that reads an opponent’s force and intent.

When I brought this idea up during the interview, Anraku nodded immediately.

“That makes complete sense to me. The sensor part — I really do think of it that way.”

From there, he described something he calls withholding reaction force.

Normally, if you grip an opponent’s hand and pull, they pull back — and you use that pull-back to set up your attack. That’s kuzushi in its usual form. Anraku does the opposite.

“I let them touch me, but I don’t push back with force at that point. People often say it feels slippery, with nothing to grab onto.”

You try to pull, and nothing catches. You want a reaction, but none comes back. To the opponent, the hand they thought they had is simply gone — there is nothing solid enough to hold onto. Denying the reaction your opponent wants to exploit is a genuinely advanced skill.

Strong Wrestlers Are Already Thinking Four Moves Ahead

The conversation naturally moved toward what separates strong wrestlers from everyone else.

“Almost anyone can execute the second move in a sequence. But strong wrestlers are already working off the fourth move. You can still think your way through the third move. The fourth move, you’re not thinking anymore — your body just goes.”

This is the part I find fascinating. Up through the third move, it’s still reading — something you can plan out consciously. By the fourth move, thought is no longer involved. The body reacts on its own.

Think less of a chess player calculating several moves ahead, and more of something that, through enough repetition, becomes pure instinct.

Feeling the Body as Five Parts and Two Parts

Another idea that stayed with me was how finely Anraku breaks the body down while he’s fighting.

He described splitting the upper body into the head, both shoulders, and both elbows, and the lower body into the hips and knees.

From there came this description:

“If you’re tense, you can’t do it. But if you’re completely loose, you can’t do it either. It’s not about relaxing everything — you keep exactly one spot from going slack.”

Locking up entirely doesn’t work. Going fully limp doesn’t work either. Keep a single core point steady while everything else stays loose — that precise balance is what produces a body an opponent can’t get a grip on.

On timing, he added:

“You watch the opponent’s rhythm, close the gap right where one beat ends and the next hasn’t started yet — that’s when you go for the kuzushi.”

Picture a steady beat — tap, tap, tap — and slipping in during the gap. You deliberately break the opponent’s tempo, entering half a beat early or late. Another way of moving someone with timing instead of force.

A Bird’s-Eye View of the Whole Match

Kuzushi isn’t something you can pull off while staring at a single point.

Anraku used top soccer players as an example:

“The best players seem to see the whole pitch from above — they just know everything that’s happening. Wrestling is the same. Your own distance, the timing of your opponent’s approach — can you hold all of that as one picture?”

Rather than fixating on one spot, you take in your opponent’s entire body from above. That spatial awareness may be exactly what makes reading four moves ahead possible.

Kuzushi Is Reverse Engineering — Designing an Almost Endless Set of Combinations

So how do you actually build this skill? Anraku’s answer was direct:

“Kuzushi is reverse engineering. You decide which takedown you want first, and then work backward to figure out how to build toward it. The ways of building it multiply on top of each other, so the possibilities are almost endless.”

You fix the goal — the technique you want — first, then work backward to the path that gets you there. Starting from A and reaching B, or starting from B and reaching A, skipping the wrist entirely if you want. There’s no single correct answer; it branches out depending on your body and your opponent’s.

Which is exactly why, in the end, you have to work it out yourself. A coach can tell you “do it this way,” but arm length and stance differ from person to person, so no instruction transfers at 100%. The wrestlers who get strong are the ones who take a borrowed form and rebuild it into their own style — that’s where the conversation eventually landed.

The Moment It Clicked: A Top Wrestler’s Instinct Matched the Book, Almost Word for Word

This is where the conversation surprised me the most.

As a researcher, I’ve been trying to explain kuzushi through data and the structure of the human body. Anraku, as an active competitor, arrived at the same place through the feel of his own body.

Two completely different positions, two completely different routes in — and yet:

– Kuzushi is about making an opponent commit an error
– The hands function as sensors
– Withholding your reaction force is itself a way to deny an opponent’s grip

None of this was planned in advance. We hadn’t compared notes beforehand. And still, the language nearly matched.

At the end of our conversation, Anraku offered this about the book:

“It’s a book that carefully puts into words the fleeting thoughts almost everyone has had at some point.”

Technical manuals exist. What’s rarer is something that systematically covers the thinking that comes before technique. A competitor with real mat experience read the research-based language and nodded along, saying it made sense. For someone who has spent years building toward this book, that was as good a confirmation as I could have asked for.

Takeaways

A quick recap of what came out of this conversation about kuzushi:

– Kuzushi means making an opponent commit an error — using their reaction, not overpowering them or outrunning them.
– Your hands function as sensors. Withholding your reaction force is itself a form of kuzushi.
– Strong wrestlers read four moves ahead, and by the last move, they’re running on instinct.
– Divide the body finely, and keep exactly one point steady while the rest stays loose. Break the opponent’s rhythm by half a beat.
– Kuzushi is reverse engineering — start from the technique you want and design your own path backward.

Kuzushi isn’t a gift you’re born with. It comes from understanding the idea, testing it in your own body, and reshaping it into something that’s yours.

Whether you’re a competitor, a coach, or simply someone who follows wrestling from a distance, I hope this way of looking at kuzushi gives you something to carry into your own next step.

Wrestle InSight is a media outlet that examines wrestling through three combined perspectives — former wrestler, coach, and researcher. It is run by Sho Ito, who moves across two kinds of knowledge — the practical knowledge built on the mat, plus the scientific knowledge built in the university. The goal is to add one step of depth to information that too often passes by as “just a vague impression.”
