The three aspects of a stance
A stance in karate isn’t a static posture. It’s a design solution — a compromise, really — to satisfy three requirements that pull against each other. Nagamine sets these out carefully in The Essence of Okinawan Karate-Dō, and the framework has stayed with me ever since I first tried to understand why Matsubayashi’s stances are the way they are rather than some other way.
The three aspects a good stance must satisfy are:
- Long endurance — the stance must be sustainable, not just for a few seconds but for the duration of a sequence, sometimes a full kata.
- Stability and balance — the stance must be resistant to being knocked over, particularly from the directions an opponent is likely to act from.
- Flexibility and mobility — the stance must permit rapid movement to any position the next technique requires.
These three pull in different directions. Endurance wants a restful posture with minimal muscular effort. Stability wants a wide, low base with a low center of gravity. Mobility wants a lighter, higher posture with weight ready to shift. No stance satisfies all three maximally; every real stance is a compromise, and the particular compromise it makes reveals what role it is expected to play.
The Matsubayashi resolution
Matsubayashi-ryū’s characteristic choice is to favor mobility in most stances. The natural stance (shizen-dachi) stands essentially upright. The front-bent stance (zenkutsu-dachi) is noticeably shallower than the same-named stance in Shōtōkan or other Japanese-influenced styles. The cat stance (neko-ashi-dachi) keeps the body light on its rear foot, ready to shift.
This mobility preference is not accidental. Matsubayashi descends from the Shuri-te tradition of Matsumura and Itosu — the bodyguard-to-the-king lineage. Bodyguards work in confined spaces, often facing multiple opponents, and cannot afford the long settling time of a very deep stance. Kyan Chōtoku, Nagamine’s central Shuri-te teacher, was known for his extreme lightness of foot; stories describe him hopping over a fence from a standstill. The natural-depth stances preserve this capacity.
Among the main Shōrin-ryū branches — Kobayashi, Matsubayashi, Shōbayashi, Matsumura Seito — Matsubayashi’s mobility emphasis is perhaps the most pronounced. Other lines preserve slightly deeper stances. These are not better or worse; they are different compromises among the three aspects.
Stances that deliberately fail mobility
Some stances in the system deliberately give up mobility in exchange for excellence in endurance and stability. The most important is naihanchi-dachi (内歩進立ち), the stance of the three Naihanchi kata.
Naihanchi-dachi is a low, wide stance with the feet turned slightly inward. The weight is evenly distributed, the center of gravity is dropped, and the stance can be held for long periods once the muscles are conditioned. It is extremely stable: you cannot easily be knocked over in naihanchi-dachi, especially from the sides, which is where the kata’s techniques primarily address attack.
But naihanchi-dachi is poor at mobility. You cannot move freely forward, backward, or diagonally from it without breaking the stance entirely. The kata reflects this: Naihanchi moves almost exclusively sideways, along a single line, because that is the direction the stance can commit to without losing its stability.
This is why Motobu Chōki — Nagamine’s teacher for Naihanchi — considered it the foundational kata of all karate. The stance teaches the body what stability feels like. Once that is internalized, the practitioner can afford to move into more mobile stances without losing the core of stability-in-the-hips that Naihanchi trains.
Sanchin-dachi, shared with the Naha-te styles (Gōjū-ryū, Uechi-ryū), is another stance that prioritizes stability and endurance over mobility. It appears in Matsubayashi only incidentally, since Matsubayashi is a Shōrin-ryū system, but the logic is identical: tension throughout the body, a narrow and rooted base, whole-body engagement. Sanchin is in this sense the Naha-te analog of what Naihanchi is to Shuri-te.
Stances that deliberately fail endurance
Some stances give up endurance and even some stability to achieve maximum mobility. These are transitory stances, designed to be occupied for a moment before moving on:
- Sagi-ashi-dachi (鷺足立ち), the heron stance, with one leg raised. Impossible to hold for long, but it is the instant-ready position for a side kick or a knee strike from a loaded leg.
- Kōsa-dachi (交差立ち), the crossed-leg stance. Poor stability in any direction except forward-backward along the crossing line, but excellent for generating forward drive and for deceptive footwork.
- Neko-ashi-dachi (猫足立ち) is an intermediate case. It can be held for a while — it appears as a committed stance at certain kata positions — but its primary function is mobility. The front foot is already off the ground on the ball, ready to kick, check, or step.
These stances are deliberately unbalanced with respect to the three aspects. They are not for sustained use. They are the system’s answer to moments when mobility is so critical that other considerations are temporarily sacrificed.
Why this framework matters
The three-aspect framework is useful for two reasons.
First, it explains why the stance vocabulary is as rich as it is. If one stance satisfied all three aspects equally, we would only need one stance. The variety of stances in the system — seventeen or more named positions, depending on how one counts — exists precisely because different combat situations demand different resolutions of the three-way tension. A kata is, among other things, a sequence of different compromises, each chosen for what it can do that a neighboring choice cannot.
Second, it clarifies what stance practice is for. A shallow zenkutsu-dachi is not a lazy version of a deep one; it is a different compromise, optimized for different conditions. A deep naihanchi-dachi is not a rigid version of a free stance; it is specialized for sideways stability. Training a stance means training its specific compromise — its strengths and its weaknesses — until the body understands what it can and cannot do from that position.
I came to karate through a drunk stranger with a stick in the dim light of a Bangalore lane. I have thought many times since about what I wish my posture had been that night. The three aspects are, among other things, a framework for thinking about that question seriously rather than in Hollywood-action-hero terms. The answer is never “the strongest stance.” It is always “the stance appropriate to the situation.” And learning the situations — which is what kata does, over and over — is what lets the body choose intelligently when it does not have time to think.
