Classification

This section gathers terminology, naming, and systematic classification of the stances in Kyokushin karate.

The purpose is to create a unified and useful structure for the library, so that the stances are named consistently and understood both as technical forms and as parts of a larger system.

The classification in this section is internal to the library and pedagogical. It does not replace traditional Japanese names, but organizes them so that they become clear in teaching, documentation, and the continued expansion of the material.


Basic principle

Each stance should be given with three levels of naming:

1. Japanese name

The established karate term, written in romaji.

2. English designation

A consistent English designation that explains the basic character of the stance.

3. Functional class

The group to which the stance belongs within the system, for example neutral, symmetrical, forward-oriented, or specialized.

This allows the same stance to be understood both linguistically and technically.


Principle for naming in the library

In the library, the following order should be used:

Romaji as the main name
Japanese characters when they are established
English designation as an explanatory translation or working name

Example:

Sanchin-dachi (三戦立ち)
Sanchin stance

or

Zenkutsu-dachi (前屈立ち)
Forward-leaning stance

The Japanese name should be normative, while the English designation should help the reader understand the function without replacing the original term.


On English designations

English designations should be:

  • consistent
  • technically clear
  • as close to the function as possible
  • free from unnecessarily loose interpretations

They should not try to be poetic or overly vague. Their task is to support understanding.

Examples of suitable types of English designations:

  • natural stance
  • open basic stance
  • forward-leaning stance
  • backward-leaning stance
  • cat stance
  • horse-riding stance

When an English term risks becoming misleading, romaji should be given greater weight.


On English equivalents in the sources

In Oyama’s English-language works, established English terms often appear, such as:

  • normal stance
  • open-toes stance
  • forward leaning stance
  • back leaning stance
  • straddle stance
  • cat stance
  • crane stance

These are useful as historical and source-close references. In this English version of the library, however, the primary structure should still be based on Japanese terms supported by clear English explanation.

These expressions may therefore be used:

  • as support in source comparison
  • as a note in comments
  • as secondary terminology

but not as the sole governing names if the broader library structure is based on Japanese terminology.


For the purposes of the library, it is recommended that the stances be classified into five main groups:

1. Neutral basic stances

Stances for starting position, order, simple structure, and basic readiness.

2. Symmetrical stable stances

Stances in which the body is carried relatively evenly and where the focus lies on stability, leg strength, and centered structure.

3. Directed main stances

Stances in which the body is clearly organized forward, backward, or centrally for technique.

4. Balance and special stances

Stances that require particular balance, unloading, or specialized body control.

5. Transitional and variant stances

Stances that function as intermediate forms, special variants, or less central basic stances.

This model is sufficiently clear for teaching and sufficiently flexible for future expansion.


Classification of the central stances

English designation: inward-angled open stance / pigeon-toed stance
Functional class: neutral basic stance

Fudō-dachi / Yoi-dachi

English designation: stable ready stance / ready stance
Functional class: neutral basic stance


2. Symmetrical stable stances

Shiko-dachi

Functional class: symmetrical stable stance

Kiba-dachi

English designation: horse-riding stance

3. Directed main stances

Zenkutsu-dachi

Functional class: forward-directed main stance

Kokutsu-dachi

English designation: backward-leaning stance / back stance
Functional class: rear-weighted main stance

Kake-dachi

English designation: hooked stance / crossed stance
Functional class: special stance


5. Transitional and variant stances

Moroashi-dachi

English designation: one-foot-forward stance / short forward stance
Functional class: variant or transitional stance


Primary and secondary stances

For the library’s internal structure, it is useful to distinguish between primary and secondary stances.

Primary stances

These form the core of the system and should be prioritized in teaching and documentation.

  • Heisoku-dachi
  • Musubi-dachi
  • Heiko-dachi
  • Fudō-dachi
  • Shiko-dachi
  • Kiba-dachi
  • Zenkutsu-dachi
  • Kokutsu-dachi
  • Sanchin-dachi
  • Nekoashi-dachi

Secondary stances

These are important but more specialized, less central, or more dependent on kata and specific contexts.

  • Uchihachiji-dachi
  • Kake-dachi
  • Tsuruashi-dachi
  • Moroashi-dachi

This division helps create progression.


Formal classification versus functional classification

A stance can be classified in at least two ways:

Formal classification

How it looks structurally.

Examples: - symmetrical - asymmetrical - high - low - one-legged stance

Functional classification

What it is used for.

Examples: - basic stance - power stance - kicking readiness - balance stance - transitional stance

Both classifications are needed, since the same stance may be simple formally but important functionally.


For consistency, each individual stance page should include the following:

Name

  • Japanese characters
  • romaji
  • English designation

Classification

  • main group
  • possible subgroup

Alternative names

  • English source names
  • older or parallel names where relevant

Comment

  • if the terminology varies between works or dojo usage

This makes it possible to keep the entire section linguistically consistent.


The following main names are recommended in the library menu and file structure:

  • Heisoku-dachi
  • Musubi-dachi
  • Heiko-dachi
  • Uchihachiji-dachi
  • Fudō-dachi
  • Shiko-dachi
  • Kiba-dachi
  • Zenkutsu-dachi
  • Kokutsu-dachi
  • Sanchin-dachi
  • Nekoashi-dachi
  • Kake-dachi
  • Tsuruashi-dachi
  • Moroashi-dachi

These should remain fixed even if alternative translations are discussed in the body text.


Summary table

Musubi-dachi open basic stance neutral basic stance
Heiko-dachi parallel stance neutral basic stance
Uchihachiji-dachi inward-angled open stance neutral basic stance
Fudō-dachi ready stance neutral basic stance
Shiko-dachi sumo stance symmetrical stable stance
Kiba-dachi horse-riding stance symmetrical stable stance
Zenkutsu-dachi forward-leaning stance forward-directed main stance
Kokutsu-dachi backward-leaning stance rear-weighted main stance
Sanchin-dachi sanchin stance centered power stance
Nekoashi-dachi cat stance rear-weighted main stance

Tsuruashi-dachi crane stance balance stance
Moroashi-dachi one-foot-forward stance variant or transitional stance

Comment

The purpose of the classification is not to simplify away the differences between the stances, but to make them clear.

When terminology, grouping, and main names are kept consistent, the entire dachi section becomes easier to expand, teach from, and use as technical reference material.
