Muay Thai vs. Kyokushin
Quick answer
Kyokushin is Masutatsu Oyama’s Japanese full-contact karate, which met Muay Thai in the early sixties, and its people later stood at the beginnings of kickboxing. Muay Thai fights in gloves with fists and elbows to the head and in the clinch, kyokushin bare-knuckle with no hand strikes to the face and no grabbing. Muay Thai has had full IOC recognition since 2021, neither is Olympic.

History and relationship
Kyokushin is Masutatsu Oyama’s Japanese full-contact karate, built on the styles Shotokan and Goju-ryu. It met Muay Thai in Bangkok in the early sixties, and its people later stood at the beginnings of both Japanese and Dutch kickboxing.
- 1953: Oyama opens a dojo in Tokyo, the name Kyokushinkai is adopted in 1957.
- Sources give February 1964 or 12 February 1963: three karateka from Oyama’s dojo fight at Lumpinee. Kenji Kurosaki lost by elbow KO to Rawee Dechachai, Nakamura and Fujihira won, 2:1 for kyokushin.
- 1964: Oyama founds IKO and the Honbu headquarters in Ikebukuro.
- 1966: Osamu Noguchi founds the Kickboxing Association. In 1969 Kurosaki leaves kyokushin and founds Mejiro Gym.
- 1972: Thom Harinck, 6th dan in kyokushin, founds Chakuriki Gym in Amsterdam, adding Muay Thai later.
- 1978: Toshio Fujiwara of Mejiro Gym becomes the first foreigner to win a Rajadamnern title.
Technique
- Eight weapons: fists, elbows, knees and shins.
- Punches and elbows to the head allowed (IFMA).
- Clinch allowed, the referee breaks it with the command yaek.
- Prohibited (IFMA): groin strikes, strikes to the ankle, to the back of the head, intentional headbutts.
- Fists, kicks and knees, bare-knuckle.
- Kicks to the head allowed, hand and elbow strikes to the face and throat prohibited (WKO).
- Kicks to the legs allowed, kicks to the knee joint prohibited (WKO).
- Grabbing, clinching and throws prohibited (WKO), Ashihara and Enshin allow a one-handed grab for a throw.
Kicks and knees are shared. The difference lies in the hands and at close range: Muay Thai aims fists and elbows at the head and fights in the clinch, kyokushin attacks with the hands only to the body. The approach without face punches was questioned by Kenji Kurosaki before he left kyokushin.
Training
| Muay Thai | Kyokushin | |
|---|---|---|
| Foundation | running, shadow boxing, skipping rope, pad work, medicine ball | kihon, kata, kumite, tameshiwari |
| Rounds | 3–5 minutes with a break of 1–2 minutes | we have not been able to document the structure of a lesson |
| Forms | none, ram muay is a ritual | kata by grade, from Taikyoku to Pinan and Yantsu |
| Conditioning | bodyweight exercises, abdominal exercises | we found no content of the conditioning part |
Muay Thai builds a lesson around pads and rounds, kyokushin around the Japanese scheme of kihon, kata, kumite, which includes board breaking. We have not been able to document the ratio of technique to sparring for either.
Progression and ranks
| Muay Thai | Kyokushin | |
|---|---|---|
| Grades | there are no unified ones, some schools use pra jiad | kyu and dan up to 10th dan, colours and order depend on the organisation |
| Milestone | the trainer hands over the mongkhon headband | Kyokushin-kan: for 1st dan 10-man kumite or an equivalent |
| Test by fighting | not documented | 100-man kumite, completed by Oyama, Steve Arneil, Shokei Matsui and Francisco Filho |
Kyokushin has an examination order in which, besides technique, a series of consecutive fights is also performed. Muay Thai has no unified grading order and the level is shown mainly by the fight record.
Physical load and risks
- Strotmeyer et al. 2016 (195 fighters): injury in the last fight in 55.4%.
- Limbs 58%, head and neck 30.6%, concussion in 5.4% of fighters.
- Sieńko-Awierianów et al. 2016 (40 practitioners of one club): injury in training in 55%.
- Piejko, Mosler and Grzebisz 2019 (questionnaire, 61 elite competitors from Poland): 548 reported injuries.
- Most often bruises (91%) and joint injuries (49%), fractures and sprains 7% each.
- A serious or lasting injury was reported by 35% of men and 12% of women.
Who it suits
| Muay Thai (IFMA) | Kyokushin | |
|---|---|---|
| Lowest competition age | categories from 10 years | we found no children’s rules of IKO or WKO |
| Upper limit | seniors up to 40 years, there are no veterans | we found none |
| Women | same weights and rules as men, chest protector, first women’s bouts at Rajadamnern in 2022 | WKO: rounds from the quarter-final 2 minutes, protector of the breasts, groin and shins |
Children
| Muay Thai | Kyokushin | |
|---|---|---|
| Competition from | IFMA 10 years, the 1999 Thai law gives over 15 years | we found no children’s rules of IKO or WKO |
| Prohibited | we found no special prohibitions for children in the IFMA rules | we found none |
| Protection | trunk protector, helmet, shin and elbow protectors | in kumite often a head guard, we found no organisation or age |
| Bout length | 3 × 1 to 3 × 2 minutes depending on age | we found none |
| Study of children | abstract (333 child boxers and 200 controls): lower IQ, declining with years of boxing | we found none |
| Physicians’ positions | Ramathibodi Hospital: up to 10 years no contact, up to 15 years no blows to the head | we found none |
Self-defence
- Sparring and clinch against a partner’s resistance.
- Fists and elbows to the head, kicks, knees.
- Modern Muay Thai does not develop ground work or weapons.
- Full contact standing, bare-knuckle.
- The rules exclude hand strikes to the head, clinching and grabbing.
- Goshin Jitsu programme influenced by Daito-ryu, we found no scope.
Both arts train standing against full resistance. Muay Thai also covers strikes to the head and the clinch, kyokushin hard bare-knuckle contact. Competition covers the ground in neither, and we found no study of transfer to real self-defence.
Practical use
| Muay Thai | Kyokushin | |
|---|---|---|
| Adult programmes | IFMA lists fitness classes for every level | we found none, apart from the self-defence Goshin Jitsu |
| Fitness study | we have not been able to document one | we found none |
| Older age | 30 seniors aged 60–70, Muay Thai dance: improved mobility and strength after 8 weeks | we found none |
For Muay Thai it is one small study with a modified dance, for kyokushin we found no study. No general conclusion about suitability can be drawn from this.
Competition
| Muay Thai | Kyokushin | |
|---|---|---|
| Bout | IFMA 3 × 3 minutes, Lumpinee at most 5 × 3 minutes | world tournaments 3 minutes, up to three extensions of 2 minutes |
| Win | points (ten-point must), KO, RSC | ippon for a knockdown longer than 3 seconds, two waza-ari are an ippon, otherwise the judges, finally also weight or tameshiwari |
| Gloves | mandatory | no gloves |
| World Championships | IFMA since 1993 | first World Open 1975, after the split each organisation holds its own editions |
Kyokushin does not score individual hits but the knockdown. For televised kickboxing in April 1969, Yamazaki and Soeno prepared for about two months at the Kyokushin Gym.
Gear and costs
| Muay Thai | Kyokushin | |
|---|---|---|
| Gloves | IFMA 10 ounces, Lumpinee 8 or 10 depending on weight | none in competition, in some non-tournament situations yes |
| Protectors | shin and elbow, helmet, groin guard, mouthguard | WKO: men groin guard, mouthguard optional, women protector of the breasts, groin and shins |

Availability and organisations
| Muay Thai | Kyokushin | |
|---|---|---|
| Organisations | IFMA, professionals WMC (since 2019 with IFMA) | IKO (Matsui), WKO Shinkyokushinkai (Kenji Midori), IKO-3, KWO (the Oyama family), IFK and others |
| Why so many organisations | – | Oyama died in 1994 without a successor, a family court in 1995 declared his will invalid |
| Grades when moving | there are no unified ones | we found no mutual recognition between organisations |
Switching and combining
- Kicks, knees and the habit of full contact carry over.
- Unlearn hand and elbow strikes to the face and the clinch.
- Add kata, kihon and board breaking.
- Kicks, knees and resilience to full contact carry over.
- Learn to cover the head against fists and elbows.
- Learn the clinch and strikes from it.
On the left the transition from Muay Thai to kyokushin, on the right the opposite direction. Terutomo Yamazaki, winner of the 1969 All Japan kyokushin tournament, knocked out Thai opponents in kickboxing and then brought kicks, elbows and knees from Muay Thai into karate. Andy Hug, who began in kyokushin, won WMTC and WKA titles in Muay Thai in 1996.
Philosophy
- Wai khru ram muay: respect for the teacher, parents and ancestors.
- Three bows to the Buddha, the dhamma and the sangha.
- The mongkhon headband as a tribute to the gym.
- The name kyokushin means roughly the ultimate truth.
- We have not been able to document a motto or a coherent philosophy of the style in verified sources.
Forms and terminology
Muay Thai has no scored forms, ram muay is a personal ritual before a bout. Kyokushin teaches kata from two lines: northern Taikyoku, Pinan, Kanku and Sushiho from Shuri-te and Shotokan, southern Gekisai, Sanchin, Tensho, Saifa, Seienchin, Seipai and Yantsu from Naha-te and Goju-ryu. The kata Garyu was created by Oyama.
Training culture
- The mongkhon as a tribute to the gym, pra jiad armbands on the arm.
- 17 March is Muay Thai Day.
- At Rajadamnern, betting with hand signals is legal.
- Tameshiwari is part of the examinations and of deciding tournaments.
- The film Fighter in the Wind (2004) tells Oyama’s story in a fictionalised form.
- Practitioners: Dolph Lundgren (European champion 1980 and 1981), Michael Jai White, Bas Rutten (honorary 5th dan Kyokushin Budokai).
Common misconceptions
- Former students describe Oyama’s completing the 100-man kumite three times in three days as impossible.
- The story of the 52 bulls: the only known recording was, according to students, staged, and the claims of breaking horns are regarded as legend building.
- The film Fighter in the Wind is not an accurate historical record of Oyama’s life, it is based on a fictionalised book.
- Researchers regard the legend of Nai Khanom Tom from 1767 as more mythological than historical.
