Kyokushinkai - "The Association of the Ultimate Truth"
Kyokushinkai Karate (極真会空手) is a full-contact, knockdown martial art, and is considered one of the most powerful and deadliest fighting styles in the world. It is a rigorous path of self-discipline, forged through intense physical training and uncompromising personal development. The name itself, Kyokushin, translates to “The Ultimate Truth” - a reflection of its founder’s (Sosai Masutatsu Oyama) lifelong pursuit of spiritual, physical, and mental mastery.
Kyokushin was founded in 1964 by Sosai Masutatsu Oyama (1923–1994), a martial artist of Korean-Japanese descent known for his unmatched strength, discipline, and philosophical depth. Oyama trained in various martial arts, including Shotokan Karate and Goju-Ryu, before creating his own school - one that would emphasize real combat, relentless training, and character development.
In the late 1940s, Masutatsu Oyama retreated to a remote shack on Mount Minobu in Yamanashi Prefecture, where he lived and trained in solitude for fourteen months, running up steep slopes, meditating under waterfalls, and forging the mental and physical endurance that later defined Kyokushin.
Titled "Kami no Te" (The Hand of God), he became internationally renowned for his legendary feats, such as fighting bulls bare-handed, engaging in the Hyakunin Kumite (100-man fight) challenges, and demonstrating the indomitable spirit that became a hallmark of Kyokushin.
Sosai Oyama’s vision was not only to create powerful fighters but also to shape individuals of great integrity. His 11 Mottos, which remain central to Kyokushin philosophy, promote perseverance, humility, self-refinement, and unshakable will.
The 11 mottos of Masutatsu Oyama reflect his personal philosophy and the deep ethical foundation of Kyokushin. These statements are more than inspirational sayings - they are the distilled principles of a life dedicated to rigorous discipline, self-overcoming, and moral consistency. Oyama intended these mottos to shape not only fighters, but human beings into people of humility and unwavering will.

The Dojo Kun (道場訓) is a formal creed recited in traditional Kyokushin (and other styles) dojos, serving as a constant reminder of the values every practitioner must uphold. It emphasizes respect, perseverance, self-control, and the pursuit of spiritual and physical perfection. These guiding principles bind the community of karateka in a shared code of conduct that transcends the mat. In the Japanese version, the number 'one' prefixes each line, emphasizing that no single line is more important than any other. Each is an equal and integral part of the whole:
First, we will train our hearts and bodies, for a firm, unshaking spirit.

Kyokushin is renowned for its full-contact sparring and rigorous conditioning, but its physical intensity is balanced by a deep philosophical foundation. Practitioners are taught to value Osu no Seishin - the spirit of perseverance and respect - and to view each challenge as a test of character. Strength is not only measured in physical terms, but also in one’s capacity to endure, to grow, and to act with honor.
Kyokushin training is built upon three pillars: Kihon (foundation), which lay the structural foundation through precise stances, strikes, blocks, and postures; Kata (form), fluid and disciplined sequences simulating combat against imaginary opponents; and Kumite (sparring), where these elements are tested and applied in the reality of direct confrontation. Training follows a progressive and rigorous path, pushing both physical and mental limits. The dojo becomes a forge - not merely of technique, but of inner strength and character.
After Sosai Oyama’s passing in 1994, Kyokushin split into several main organizations, each preserving different aspects of his legacy. While this division has led to variations in leadership and curriculum, all schools maintain the foundational principles of Kyokushin Karate. A comprehensive list of all the recent heads of the international Kyokushin Karate Federations can be found here.
The expression "Kyokushinkai" is composed of three kanji characters:
極 (Kyoku) – Ultimate
真 (Shin) – Truth
会 (Kai) – Society or Assembly
Together, they define a path and a community bound by the search for truth through effort, pain, and transformation. To be a Kyokushin practitioner is to walk a path where shortcuts are rejected, and illusions are stripped away, leaving only the raw encounter with one’s limits, and the power to transcend them.
The structured grading method in organizations such as the International Federation of Karate (IFK) and British Kyokushinkai Karate (BKK) reflects both tradition and rigor, guiding students from white belt to black belt with precision and purpose.
Kyokushin uses the Kyu/Dan system, adapted from traditional Japanese martial arts. Students begin at Mukyu (white belt - no rank) and move downward to 10th Kyu, 9th Kyu, 8th Kyu, all the way to 1st Kyu (brown belt with a stripe) before testing for black belt, or Shodan (1st Dan). Each level demands not only increased technical ability and physical conditioning, but deeper understanding of etiquette, mindset, and fighting spirit.
The typical progression is as follows:
10th–8th Kyu: White and orange/red belts – Fundamentals of stances, blocks, basic strikes, and etiquette.
7th–6th Kyu: Blue belts – More advanced kihon, basic kata, and light contact sparring.
5th–4th Kyu: Yellow belts – Increased intensity in kumite and introduction to complex kata.
3rd–1st Kyu: Green and brown belts – Greater expectations in power, fitness, control, spirit, and understanding of principles.
Shodan (1st Dan) and above: Black belts – Rank is no longer just about skill but continuous contribution, depth, and refinement.
Each grading requires demonstration of Kihon (fundamental techniques), Kata (forms), and Kumite (sparring), with emphasis on discipline, focused power (Kime - 決め), and the ability to endure fatigue and adversity with composure.
Higher Dan grades (Nidan, Sandan, etc.) are not earned through performance alone but reflect years of dedication, teaching, and embodiment of Kyokushin’s values.
In IFK and BKK-affiliated dojos, gradings are standardized to ensure consistency across the global network. This unity of standards allows practitioners from different countries to speak the same language of technique and spirit - regardless of geography.
