Kyokushin knowledge

Kyokushin

Kyokushin is a full-contact system within modern Japanese karate, founded by Sosai Masutatsu Oyama (1923–1994). The system was organizationally formalized in 1964 through the International Karate Organization Kyokushinkaikan.

Kyokushin (極真) means “ultimate truth.” Here, Kyokushin refers to the style and training system, while Kyokushinkaikan refers to the organizational tradition that developed around the system.

Read the system in this order

To understand how Kyokushin fits together, begin with its background and follow how history, founder, principles and structure build on one another.

  1. Historical Background – the context from which Kyokushin emerged.
  2. Sosai Masutatsu Oyama – how Oyama’s experience shaped the method.
  3. System Principles – the principles governing function, load and technical development.
  4. System Structure – how kihon, kata, kumite and tameshiwari work together as a system.

This is the main path through the Kyokushin section. After System Structure, the material branches according to what you want to understand or practise next.

The four training components

Kyokushin’s technical system is built on four interdependent components:

  • Kihon – fundamental technique and body structure.
  • Kata – formalized movement systems.
  • Kumite – application and testing against active resistance.
  • Tameshiwari – functional verification of power and technique.

The Kyokushin section explains how the system is structured. Training explains how it is practised, while Techniques contains the concrete technical definitions.

The principle of function

A central formulation within the system is Ichi Geki, Hissatsu – “one strike, decisive effect.” Here the principle is used as a technical norm: movement should have functional integrity and remain effective under real load. It should not be read as a literal doctrine of lethal violence.

Its deeper normative and philosophical meaning is treated in Ichi Geki Hissatsu.

After the system structure

Once you have followed the main path, continue in the branch that matches what you need.

Training

Go to Training for practical method: Jumbi undō, breathing, kihon, kata, kumite, tameshiwari, physical training, progression and safety. The Knockdown System belongs to this branch as a regulated competition format connected to kumite, not as a summary of Kyokushin as a whole.

Philosophy

Go to Philosophy to follow how Kyokushin formulations become practice: Dojo Kun and Oyama's mottoes state the ideals, shugyō describes the process, Osu the attitude, kokki the self-discipline, and the remaining pages show how these are expressed in the dojo, technique and grading.

Tradition and institution

The organizational and formal side of the tradition is covered in:

From system to practice

When you want to move from understanding to concrete work, use Techniques as the reference library and Grading for requirements, progression and grading material.
