On 7 August 2021 in the Nippon Budokan, Tareg Hamedi of Saudi Arabia landed a jodan kick that put Sajad Ganjzadeh of Iran unconscious on the tatami. Under WKF rules the kick was not a three-point ippon. It was hansoku, disqualification for excessive contact, and Ganjzadeh left the hall on a stretcher as Olympic champion. If you did not understand karate scoring before that night, you were in good company, and the sport has been explaining itself ever since.
The short answer: WKF kumite, the Olympic version, is a points contest with a ceiling on contact. Punches score one, kicks to the body two, kicks to the head three, and hurting your opponent costs you the bout. Kyokushin knockdown karate is the mirror image: full contact, no gear, no punches to the head, and the aim is to put the other person on the floor. Shotokan's ippon shobu sits between them. Same word, karate, three scorecards.

WKF: the price list
Under World Karate Federation rules, which are what most clubs mean by sport kumite, a technique scores only if it meets six criteria at once: good form, sporting attitude, vigorous application, awareness (zanshin), good timing and correct distance. A punch that lands but was thrown falling forward with the eyes shut is not a point.
| Score (WKF, as of 2026) | Points | Techniques |
|---|---|---|
| Yuko | 1 | Punches (tsuki) and strikes (uchi) to the head, body or back |
| Waza-ari | 2 | Kicks to the body (chudan) |
| Ippon | 3 | Kicks to the head (jodan); any scoring technique on an opponent who has been thrown, swept or has fallen |
Contact is controlled: a light touch to the face is allowed for seniors, and anything that injures the opponent is penalised, however clean. The referee stops the bout for every score, so three minutes of kumite is a series of short bursts rather than a fight.
Senshu, the eight-point lead and the clock
Bouts are three minutes for seniors, as of 2026, and two for cadets and juniors, with the clock stopped on every yame. A lead of eight points ends the bout early. Otherwise the higher score wins, and a tie goes to senshu, the first unopposed point. Senshu has a catch: an athlete who holds it and is warned for avoiding combat in the last fifteen seconds loses it. If nobody holds senshu, the judges vote by hantei, raising the flag of the athlete they think showed more.
Five people, four pairs of flags
The rule changes agreed at the end of 2018 and applied from January 2019 rebuilt the officiating. The panel is a referee in the ring and four judges at the corners, each holding a red flag and a blue one, and the judges score: a technique needs at least two flags to count, while the referee manages the bout, gives the penalties and reads the flags.
Two kinds of foul
WKF penalties come in two categories. Category 1 is contact: excessive contact, attacks to the throat, groin, joints or instep, open-hand techniques to the face, dangerous throws. Category 2 is conduct: feigning injury, stepping out of the area (jogai), endangering yourself by carelessness (mubobi), avoiding combat, grabbing or clinching without attacking.
Within each category the ladder is the same: chukoku, a warning; keikoku, a second warning; hansoku-chui, the last one; hansoku, disqualification. The two ladders are climbed separately, so an athlete can be one warning from hansoku for contact while clean on conduct. Hamedi in Tokyo went straight to the top of the first ladder.
Tokyo 2020: one Olympics, and probably the last
Karate's only Olympic appearance was in the Nippon Budokan in August 2021. There were three kumite classes per gender, −67, −75 and +75 kg for men (148, 165 lb) and −55, −61 and +61 kg for women (121, 134 lb), and a kata event for each. Ryō Kiyuna won the men's kata at home and Sandra Sánchez the women's, and the men's +75 kg final ended with the champion unconscious and the runner-up in tears. Karate was not retained for Paris 2024 or Los Angeles 2028.
Kyokushin: knockdown
Mas Ōyama founded Kyokushin in Tokyo in 1964, and its knockdown rules are the answer to the WKF's controlled touch. Senior men wear a gi and nothing else. Punches, elbows and knees go to the body and legs with full power; kicks and knees may go to the head. Hand strikes to the head and neck are forbidden, and so are attacks to the groin, the spine and the knee joint, and grabbing the opponent.
A bout under IKO rules is three minutes, with extension rounds of two minutes if it is undecided. Ippon is the opponent knocked down for three seconds or more, or unable or unwilling to continue. Waza-ari is a knockdown the opponent recovers from inside three seconds, or a technique that visibly breaks the opponent's stance; two waza-ari make ippon. If neither happens, the referee and four corner judges decide by flags, and at the World Open Championship an undecided bout can go to weight difference and then to tameshiwari, board breaking, before a final extension. Warnings, chui, accumulate to a penalty point, genten, and a second genten is disqualification.
Over all of it sits the hyakunin kumite, the hundred-man fight: a hundred consecutive bouts against fresh opponents. Ōyama set it as the test of a Kyokushin master, and Steve Arneil was the first person after him to complete it, in 1965. The list of everyone who has managed it since fits on one page. Kyokushin fractured into several organisations after Ōyama's death in 1994, but the shape of a knockdown bout is the same everywhere: you win by hurting the other person, within limits, and nobody stops the clock to check a flag.
| WKF kumite | Kyokushin knockdown | |
|---|---|---|
| Contact | Controlled; excessive contact is penalised | Full contact |
| Hand strikes to the head | Score one point, with control | Forbidden |
| Kicks to the head | Ippon, three points, with control | Allowed with full power |
| Protective gear | Gloves, shin and instep pads, mouthguard, body protector | None for senior men; chest protector for women, pads for juniors |
| How you win | Points, an eight-point lead, senshu, hantei | Ippon by knockdown, two waza-ari, or a flag decision |
| Bout time | 3 minutes for seniors | 3 minutes plus 2-minute extensions |
| Throws and sweeps | Allowed with control, scored when followed by a technique | Not allowed |
Shotokan and the JKA: one point and it is over
Before the WKF's point tables there was ippon shobu, the one-point match, which the Japan Karate Association still uses. A technique either would have finished a real fight or it would not, and the referee is looking for todome, the finishing blow. A full ippon ends the bout at once; two waza-ari make an ippon and end it the same way. The bouts are short, since a fighter who has taken one decisive technique has already lost. It is the least forgiving scoring system in karate and, to its admirers, the only honest one.
Three karates, three answers to the same question, which is what a punch is for. The WKF says scoring, Kyokushin says hitting, and the JKA says ending things. All three are right, and you will fight better under any of them once you know which one you are in.

Frequently asked questions
- How is karate kumite scored under WKF rules?
- Yuko is one point for a punch or strike, waza-ari two points for a kick to the body, ippon three points for a kick to the head or any scoring technique on an opponent who has been thrown, swept or has fallen. A lead of eight points ends the bout.
- What is senshu in karate?
- The first unopposed point of the bout. If the score is tied at the end of time, the karateka holding senshu wins. Senshu is lost if that athlete is warned for avoiding combat in the last fifteen seconds; if nobody holds it, the judges decide by hantei.
- How long is a karate kumite bout?
- Three minutes for seniors under WKF rules as of 2026, with the clock stopped for each score and penalty. Cadets and juniors fight two minutes. Kyokushin knockdown bouts are three minutes with extension rounds of two minutes.
- Why can't you punch to the head in Kyokushin?
- Kyokushin knockdown rules allow full-contact kicks and knees to the head but forbid hand strikes to the head and neck, because the fighters wear no gloves and no head protection. Punches, elbows and knees go to the body and legs with full power.
- What is ippon shobu?
- The traditional one-point match used in Shotokan and JKA competition. The first ippon, or two waza-ari, wins the bout outright, and techniques are judged on whether they would have ended a real fight.
- Is karate still in the Olympics?
- No. Karate was on the programme once, at Tokyo 2020, with three kumite classes per gender and a kata event. It was not included for Paris 2024 or Los Angeles 2028.
