01The short answer
02The name, and what Oyama was reacting to
The word kyokushin (極真) means something close to “ultimate truth”. The name was a position, not decoration: Oyama's argument was that karate had drifted toward technique that was never tested against someone trying to stop it.
Masutatsu Oyama trained in Shotokan and later in Gōjū-ryū under So Nei-chu, though accounts disagree about the exact sequence and about which other teachers shaped him. The lineage is less tidy than it is usually told. What is documented is the institutional timeline: Oyama was teaching in Tokyo by the early 1950s, the Ikebukuro honbu dojo was completed in June 1964, the first All-Japan championship was held in 1969, and the first World Open in 1975. Our page on Mas Oyama covers the man himself.
03What the knockdown rules actually say
This is worth reading carefully, because almost every summary online gets one part of it wrong. The rules below are the WKO knockdown rules; other Kyokushin organisations differ on detail.
- Strikes land at full power to the body and legs, with bare hands and bare feet.
- Kicks to the head are legal, and a head kick that ends a bout is the image the format is known for — but the score follows the effect of the technique, not the target it reaches.
- Hand and elbow strikes to the face and neck are forbidden, and can bring disqualification.
- Also forbidden: strikes to the groin, head butts, grabbing the uniform, attacking an opponent from behind, and striking an opponent who is down.
- Under those rules, senior competitors wear a groin guard and shin protectors (men) or a chest protector and shin protectors (women). No gloves. No head guard.
- Senior bouts run three minutes, then two, then two.
- Scoring is built around stopping the opponent, not touching him: ippon requires a technique that visibly takes him out of the fight, and two waza-ari add up to one. What that standard does to the way people fight is a subject in itself.
And the detail that most articles miss: the foot sweep, ashi-barai, is legal and appears in the scoring criteria. “No grabbing” does not mean “striking only”. Sweeping an opponent's supporting leg and following up is part of the format, not an exception to it.
04What a class contains — which is not the same list
A Shinkyokushin class follows a recognisable sequence: warm-up and mobility, kihon (basics in lines), ido-geiko (basics moving up and down the floor), kata, pad and bag work, kumite, then a closing with the dojo kun. In many dojos the students clean the floor together at the end, and that is treated as part of the session rather than a chore afterwards.
Notice what is in that list that is not in the rule book. Kata remain part of grading in the major Kyokushin organisations, and no kata has ever won a knockdown match. Some dojos teach material that would be illegal in competition outright. The rule set defines how the style competes; it does not define what the style teaches — and if you only read about the tournaments, you end up with a picture of Kyokushin that no student would recognise. What a session actually looks like is its own subject.
05Belts, and what a black belt costs in rounds
Kyokushin uses coloured belts leading to black (dan) grades, with stripes marking intermediate steps. Gradings test kihon, kata, stamina and kumite together, so nobody advances on technique alone.
The part that surprises people is that a dan grading includes a run of consecutive bouts — not one demonstration match, a series of them, back to back, after the kata and the breaking. The number is documented for examinations held here in Québec, and we give it in how tough is Kyokushin, really, where it does more work than it would here.
06One style, several organisations
After Oyama's death in 1994 the original organisation fragmented. Today you will meet the IKO, the WKO Shinkyokushinkai, the IFK, the KWF, Kyokushin-kan and others. The circumstances of the 1994 succession are disputed — different organisations tell it differently, and we are not in a position to adjudicate.
What actually changes for a student is narrower than the politics suggest: competition format details, grading requirements, which seminars and championships you have access to. The technical base is shared. Sensei Alexandre Haché and his dojo are currently listed within the WKO Shinkyokushinkai / Camille Ohan Branch network; his page sets out his background.
07Who it fits, and who it does not
Practitioners who stay tend to describe the same draw: a traditional framework — etiquette, kata, grading — combined with sparring that is genuinely tested. Several describe being unwilling to accept a technique they had never felt fail. If repetition bores you, that is worth knowing before you sign up; kihon is not a phase you get past.
It is a poor fit if the thing you specifically want to train is punching to the head, clinch work or ground fighting. Those belong to other systems and we say so on our comparison pages. And if kata is the part you are dreading — a common hesitation among people drawn to the fighting — the honest answer is that the weight given to kata varies a great deal from dojo to dojo. Ask the specific dojo, not the internet.
