Kyokushin vs. Kudo

Kyokushin極真More about the art →Kudo空道More about the art →

Quick answer

Kudo was founded in 1981 as Daido Juku by Azuma Takashi, a former Kyokushin competitor. Kyokushin fights full contact bare-handed, standing, without hand strikes to the face, and has kata as a basis, while kudo allows strikes to the head in a helmet with a plexiglass visor, throws, joint locks and chokes, and abolished kata. We have not found a link to the Olympic programme for either of them.

History and relationship

Kudo grew directly out of Kyokushin. Azuma Takashi entered Kyokushin in 1971 or 1972 (sources differ), founded a Kyokushin club at Waseda University, placed second at the All Japan Open Kyokushin tournament in 1974 and won it in 1977. In 1981 he founded his own organization, Daido Juku, which extended the Kyokushin rules with hand strikes to the face and throws.

  • 1964: Masutatsu Oyama founds the IKO and its headquarters in Tokyo.
  • 17 February 1981: Daido Juku begins operating in Miyagi Prefecture, and until 2001 the style is called kakuto karate.
  • 6 September 1981: the first national Hokutoki tournament, with categories by build.
  • 1994: Oyama dies without a designated successor and Kyokushin splits into a number of organizations.
  • 2001: Azuma announces the name kudo, and the first world championship is held in Japan on 17 November 2001.
  • 2021: after Azuma’s death, Daido Juku is led by Kenichi Osada.

The stated reasons for its creation are Azuma’s concerns about serious head injuries in Kyokushin and the disadvantage of smaller fighters. Jon Bluming, the founder of Kyokushin Budokai, awarded Azuma the 9th dan.

Technique

Kyokushin
  • Punches, knees and kicks at full power without gloves.
  • Kicks to the head allowed, hand and elbow strikes to the face and neck forbidden (WKO).
  • Forbidden (WKO): throws, grabbing, pushing, hugging, headbutts and strikes to a downed opponent.
  • Fighting only standing, stopped at a knockdown, a sweep or a clinch.
Kudo
  • Punches, elbows and headbutts, also to the head, in a helmet with a plexiglass visor.
  • Throws, holds, joint locks and chokes, with victory also by submission or choke.
  • Clinch at most 10 seconds, on the ground at most 30 seconds twice.
  • Forbidden: strikes to the back and groin, for youth strikes on the ground.

Kyokushin decides by knockdown, while kudo scores with the grades koka, yuko, waza-ari and ippon, and the point values differ between sources. We have not been able to document whether kudo allows knees and kicks to the head.

Training

KyokushinKudo
Componentskihon, kata, kumite, tameshiwari (Kyokushin-kan curriculum)we have not found the K.I.F. curriculum
Katafor kyu examinations: Taikyoku, Pinan, Sanchin, YantsuKyokushin kata abolished without replacement
Lesson structurewe have not found itwe have not found it

The difference is most visible in kata: in Kyokushin they are part of examinations from the first grades, while kudo dropped them. We have not been able to document the content of a regular class or the ratio of technique, sparring and conditioning for either style.

Progression and ranks

KyokushinKudo

Who awards themeach organization separatelyDaido Juku and K.I.F., we have not found a single international table

Besides kumite, Kyokushin also examines kata, while in kudo kata are not part of examinations. Azuma also awarded dan grades to Russian masters, and Roman Anashkin received the 6th dan in 2013 as the first competitor outside Japan.

Physical load and risks

Kyokushin
  • Piejko, Mosler and Grzebisz 2019 (61 elite competitors from Poland): 548 reported injuries, contusions 91%, joint injuries 49%.
  • Hands and legs most often affected, a serious or permanent injury was reported by 35% of men and 12% of women.
Kudo
  • We have not found an injury study of kudo with figures.
  • The helmet with a plexiglass visor is mandatory and is meant to protect against head injuries, and we have not found a study of its effect.
Studies are lacking for kudo, so the two arts cannot be compared by injuries. The authors of the Kyokushin study do not generalize the results beyond competitors. With a medical limitation, it is advisable to consult a doctor before starting.

Self-defence

Kyokushin
  • Full contact bare-handed, standing.
  • The rules exclude the clinch, grips and hand strikes to the head.
  • The Goshin Jitsu programme influenced by Daito-ryu, we have not found its scope.
Kudo
  • Strikes also to the head, clinch, throws, joint locks and chokes in one bout.
  • Clinch and ground are time-limited, and the bout takes place in a helmet and gloves.
  • We have not found self-defence instruction in kudo.

Kyokushin trains full resistance only standing, while kudo also does so in the clinch and on the ground, but with a time limit. We have not found a study of transfer to self-defence for either of them.

Outside Japan, the beginnings of kudo are documented in Russia: the first section arose in 1991 in Vladivostok, and the Russian kudo federation, according to sources, in 2002 or 2004. After 1994 Kyokushin divided into many organizations with their own grades and belts.

Switching and combining

Kyokushin
  • Kicks, knees and the habit of full contact to the body remain.
  • Learning to cover the face against hand strikes, elbows and headbutts.
  • Adding the clinch, throws, joint locks, chokes and ground fighting.
  • Getting used to the helmet with a plexiglass visor and gloves, kata fall away.
Kudo
  • Kicks and strikes to the body remain.
  • Unlearning hand and elbow strikes to the face, headbutts, grips, the clinch and throws.
  • Getting used to being hit bare-handed without a helmet and gloves.
  • Learning kata according to the organization’s curriculum.

On the left the transition from Kyokushin to kudo, on the right the opposite direction. Azuma himself, the winner of the All Japan Kyokushin tournament in 1977, took this path. We have not found other documented transfers.

Frequently asked questions

Is kudo an offshoot of Kyokushin?

Yes. Azuma Takashi was a Kyokushin competitor and founded Daido Juku in 1981 with Kyokushin as its starting basis. Kudo, however, abolished kata and extended the rules with strikes to the face, throws and the ground.

May both be fought with hand strikes to the head?

Not in Kyokushin, where the WKO rules forbid hand and elbow strikes to the face and allow kicks to the head. In kudo yes, in a helmet with a plexiglass visor, and elbows and headbutts are also allowed.

Why is a helmet worn in kudo?

The stated reason for the creation of Daido Juku is Azuma’s concern about serious head injuries in Kyokushin. We have not found a study showing a lower risk of injury in kudo.

Is either of them Olympic?

We have not found a link to the Olympic programme for either Kyokushin or kudo.
