Kata / structure

Introduction

A kata has an external and an internal structure. The external structure consists of the order of movements, directions, and techniques. The internal structure consists of balance, breathing, rhythm, power, intent, and zanshin.

For kata to become technically useful, both levels must be trained.

Name

Each kata has a name. The name may indicate an idea, an origin, a technical character, or a traditional meaning. The name should not be overinterpreted, but it helps the student understand the kata form’s place within the system.

On Galaz Dojo pages, the name is primarily given as:

Romaji (kanji/kana)
English explanation

When the kanji or translation is uncertain, this should not be stated as absolute.

Rei and starting position

Kata begins with formal posture and respect. The starting position gathers the body and mind before movement begins.

The start should show:

  • upright posture
  • calm breathing
  • control
  • correct direction
  • readiness without unnecessary tension

Yoi

After rei, the practitioner normally moves to yoi or an equivalent ready position. Yoi is not rest. It is a controlled starting point where the body is ready to move.

Embusen

Embusen is the movement line of the kata form. It shows how the practitioner moves through space: forward, backward, to the side, diagonally, and through turns.

Embusen helps the student understand:

  • direction
  • footwork
  • starting and finishing point
  • balance in turns
  • the relationship between sequences

Technical sequences

A kata often consists of technical phrases. A phrase may consist of a block, a movement, a strike, a kick, a control, or a combination.

Not every movement needs to be understood as one long continuous fight against many opponents. Some movements function as technical links between different phrases.

Turns

Turns are central in kata. They show whether the student can shift the center of gravity, direct the hips, and maintain balance.

A correct turn requires:

  • stable foot contact
  • controlled hip rotation
  • clear direction
  • maintained posture
  • technique that finishes at the same time as the stance

Breathing points

Some techniques require a clear exhalation. Others require softer breathing or slow control. In breathing kata, especially Sanchin and Tenshō, breathing is a fundamental part of the form.

Kiai

Kiai does not mark sound only. It marks gathering of power, intent, and technical completion. Kiai points should follow the standard of the kata form and should not be added freely.

Finish and return

Kata should finish with the same control with which it begins. After the final technique, zanshin should be maintained before the practitioner returns to the closing position.

A kata whose ending falls apart shows that the student has not carried the form all the way through.

Commentary

Kata structure makes it possible to repeat, review, and refine technique. Therefore, each kata page in Galaz Dojo Technical Library should describe both the external order and the internal technical logic.
