半月立ちHangetsu-dachi — Half-moon stance

Hangetsu-dachi (半月立ち, “half-moon stance”) is a mid-length tension stance with the feet turned inward and the knees rotated in, and a signature semicircular (“half-moon”) stepping path. It is essentially unique to the Hangetsu kata, which shares its name.

How to perform it

Set a stance shorter than a front stance but longer than sanchin-dachi, feet about shoulder-width apart, weight 50/50.
Turn the toes inward so lines from the feet converge on the opponent’s centre — a triangle between your feet and their centre.
Bend and rotate both knees inward, keeping the same inward tension as sanchin-dachi over the longer base.
Engage the buttocks, abdomen and legs with isometric contraction; keep the posture upright and the breathing strong and deliberate.
When stepping, travel the moving foot in a semicircular arc — into the centre, then curving forward — not a straight line.

Key points

Feet turned in, knees rotated inward with tension.
Mid-length — between front stance and sanchin.
The stepping foot traces a crescent arc — the signature of the kata.

Common mistakes

Stepping in a straight line instead of the crescent arc.

Losing the inward knee tension or letting the knees drift out.

Making it too long (like a front stance) or too short (like sanchin).

Holding the breath instead of the deliberate tension-and-breathing.

Where you’ll see it

Hangetsu-dachi appears across the Shotokan kata syllabus, including:

Hangetsu

Application (bunkai)分解

The inward-tension base and the arcing step suit close-range control — angling in, trapping and unbalancing — while the compression-and-release breathing trains the body’s core connection.

Note: applications are interpretive and one shape carries several valid uses — explore them with a qualified instructor.

Hangetsu-dachi — frequently asked questions

What does hangetsu mean, and why is it called half-moon?

Hangetsu (半月) means “half moon.” The name comes from the crescent, arc-shaped path the stepping foot traces — curving into the centre line, then forward — rather than moving straight.

What kata is hangetsu-dachi used in?

Essentially only the Hangetsu kata. The stance is unique to that kata in the standard Shotokan curriculum, which is why they share a name.

What is the difference between hangetsu-dachi and sanchin-dachi?

Both are inward-tension stances. Sanchin-dachi is short and compact; hangetsu-dachi is longer and adds the semicircular stepping path. Hangetsu is Shotokan’s lengthened version of the older sanchin.

Where does the Hangetsu kata come from?

It descends from the Okinawan Naha-te kata Seisan/Sanchin. In the Shuri-te line the short stances were lengthened, and Funakoshi adopted it into Shotokan as the tension-and-breathing kata.
