Sanchin-dachi 三戦立ち

Hourglass stance

What it is

The technique, and its job.

A short, rooted stance with the feet turned inward and the knees drawn together, one foot advanced by about a foot-length. It belongs to the Naha-te lineages rather than to Shotokan proper, and appears in this library because Shotokan students meet it in cross-style training and because hangetsu-dachi is its close relative.

Application. Close-range rooted work in the Naha-te lineages. Included here for completeness and cross-reference, explicitly flagged as not native to Shotokan.

Mechanics

What each part of the body does, in the order it does it.

Weight distribution
Even, low, and rooted downward.
Feet
Both turned inward, heels roughly on the corners of a small rectangle, one foot advanced by about its own length.
Knees
Bent and drawn inward under continuous tension.
Centre of gravity
Hips tucked, abdomen strongly engaged, spine long.
Breathing
Central to the stance in the styles that own it, and the reason it exists.
Principles

What survives when the name is forgotten.

  1. It is a conditioning posture before it is a fighting one.
  2. Its relationship to hangetsu-dachi is the useful thing for a Shotokan student: the same idea, adapted.
1 faults

Common errors, and how to fix them.

Naming a fault teaches nobody. Each one below carries why it happens and what corrects it.

Fault
Practising it as a Shotokan stance.

Why it happens. Assuming every stance in a karate curriculum belongs to the same lineage.

The fix. Learn it from the tradition that owns it, and do not import its tension into Shotokan stances where it does not belong.

Drills

  • Best trained under an instructor of a style in which it is native.
Where Shotokan does not agree

This one is not settled.

Sanchin-dachi is not a Shotokan stance. It is documented here because the directive lists it "where applicable" and because students encounter it; it is not presented as part of the Shotokan canon.

It is written here rather than resolved silently, because a student whose instructor teaches it the other way should find that acknowledged and not contradicted.

Kihon ↔ kata ↔ kumite

Where it appears.

Kihon is the vocabulary, kata is the literature, kumite is the conversation. Every link below was written down deliberately; none of it was inferred from a name matching.

Kata
No kata is recorded as containing Sanchin-dachi uncontroversially. That is an absence of a recorded link, not evidence that it appears in none.
Kumite
No kumite principle is recorded against this technique.

Reference recordings

Video

No recording in the register is tagged to Sanchin-dachi. MMAKF has not filmed this technique, and the discovery pass did not find an external recording specific enough to attribute to it without guessing.

Nothing is shown here rather than a search link dressed up as a demonstration. What has been found, checked and registered is listed in full on the source register.
