Shinkyokushin Karate: From Japan to Thailand

Kyokushin Karate grew from Masutatsu Oyama's approach and became a major root of full-contact karate. After his death in 1994, the original organisation entered a transition involving succession, governance, and naming rights.

This article does not decide which organisation owns the art's essence. It uses that transition to explain why several organisations now share Kyokushin roots while operating under different structures.

The disputes in Japan involved organisational succession, names, and trademarks. The legal record is complex, and translated excerpts are not substitutes for complete court documents, so precise claims should be treated cautiously.

What can be said without overreaching is that the post-1994 period led branch leaders and practitioners to form several organisational paths, providing context for the later Shinkyokushinkai identity.

In 2003, the group led by Kenji Midori adopted the World Karate Organization Shinkyokushinkai name to present a clearer organisational identity. Shin, or 新, signals a new chapter.

For a detailed account of Mas Oyama, Kenji Midori, and the Kokoro symbol, read the separate history article so this page can focus on the route from Japan to present-day training in Thailand.

What makes Shinkyokushinkai stand out in my eyes is its courage to push the organization toward becoming a full-fledged professional sport. I have followed news of global events hosted by Japan HQ for years, and I must admit that Kenji Midori's ambition to raise full-contact karate into an economically viable sport is remarkable. The annual Karate Champion of Champions tournament in Tokyo boasts total prize money of 30 million yen—the highest figure in the world of full-contact karate.

An investment of this scale did not happen by chance; it was a carefully planned strategy to attract top-tier fighters from around the globe to the Shinkyokushinkai arena. In the martial arts world, elite fighters naturally seek arenas with high standards, attractive prize money, and international media broadcasts. When world-class fighters enter, it further inspires new practitioners to learn this style, creating a continuous cycle. This was one of the key reasons I chose this affiliation for my students in Thailand: when my students become skilled enough, they will have a world-class platform awaiting them, not just domestic competitions.

Another topic I have followed with special interest is the Japanese karate community's efforts to push the sport into the Olympic Games. Although karate participated in the Tokyo 2020 Olympics once, the format used was WKF karate, which relies on a point system rather than the full-contact sparring characteristic of Kyokushin or Shinkyokushin. Many full-contact practitioners worldwide felt regretful, viewing full-contact fighting as the true essence of "karate" (meaning empty hand).

Shinkyokushinkai, under Midori's leadership, worked alongside the Japan Fullcontact Karate Organization (JFKO) to push full-contact karate toward recognition by national sports associations and pave a path toward becoming a demonstration or core Olympic sport in future games. However, these efforts faced major hurdles: the existence of multiple organizations and rulesets in Japanese karate led the International Olympic Committee to choose the unified WKF system, which was easier to standardize and manage in terms of injuries. While regrettable from a sports history perspective, missing the Olympics had a positive side: it allowed Shinkyokushinkai to preserve the intensity of traditional competition rules without having to "soften" them to meet IOC international standards.

WKO's organisation page states that it had 100,000 registered members across 102 countries and regions as of March 2021. That figure is date-specific and should not be converted into a current dojo count without a newer source.

Grading and kumite requirements vary by level, country, and current examination policy. Students should confirm the actual requirements for their grading cycle instead of assuming one fixed opponent count applies to every rank.

I would like to share my family's personal story, as I believe it will help give you a better overall picture of the karate scene in Thailand. Our family's journey did not begin with Shinkyokushinkai, but with IKO Kyokushin (International Karate Organization Kyokushinkaikan), another major organization preserving Kyokushin karate. Instruction in Thailand at that time was supervised by a Shihan who traveled periodically from Singapore. I brought my wife and four children to train with simple intentions: wanting our family to build discipline, stay physically fit, and learn basic self-defense. I never imagined I would fall in love with the philosophy of this martial art myself.

Over time, due to teaching approaches and methods of knowledge transfer that aligned more closely with what our family was seeking, I had the opportunity to learn about and transition to training under WKO Shinkyokushinkai (World Karate Organization Shinkyokushinkai). As mentioned earlier, this organization is centered at its Japan HQ for standards, with Shihan Frank Nagashima directly managing instruction for Karate Shinkyokushin Thailand.

What I experienced clearly during this transition was the nuanced difference in teaching contexts between Thai and Japanese instructors. Although basic techniques are identical, the explanatory methods, building of understanding, and ways of connecting with students carry distinct charms. Japanese instructors often emphasize traditional discipline and rigor, whereas Thai instructors tend to be gentler in explaining the reasoning behind each movement. I view both approaches as inherently valuable. This sparked my belief that by combining Japanese intensity with an understanding of Thai cultural context, we could create the best possible instructional environment for Thai children and adults.

Our entire family trained consistently for years—myself, my wife, and all four children—until every single one of us passed the examinations and earned our black belts. I still vividly recall the feeling of standing in line to receive our black belts in front of Shihan Frank Nagashima. It was not a feeling of pride in victorious superiority over others, but a sense of profound relief mixed with a deep understanding that this black belt was not the end of learning. Instead, it was the start of a heavier new responsibility. In Kyokushin philosophy across all branches, a black belt signifies becoming an "instructor" accountable to future generations, not graduating and packing up to go home.

With the trust granted by Shihan Frank Nagashima and the relationships built over years under Karate Shinkyokushin Thailand, I was given the opportunity to officially open my own dojo under the name IMAC Dojo, located in the Lat Phrao 101 area (known to many parents as Shinkyokushin Karate Ladprao 101). I chose this location because it is near a dense community of families and working adults, easily accessible, and in a neighborhood I have been familiar with for decades. I wanted locals to have access to genuine, world-standard full-contact karate training, rather than superficial karate learned just for small talk or wearing uniforms for social media photos.

The principle I have held firmly since day one at IMAC Dojo is "Thais teaching Thais" while preserving traditional training standards as close to Japan as possible. I believe this balance is vital: if we lower standards too much to make Thai students comfortable, the value and intensity of Shinkyokushin Karate disappear. Conversely, if we enforce Japanese-style rigor without adapting to Thai psychology and context, students feel overly pressured and quit prematurely. Thus, I strive for a middle ground where Thai children and adults can deeply grasp the core of this martial art without feeling alienated or overly coerced.

I frequently receive this question from parents bringing their children to IMAC Dojo: "How does Shinkyokushin Karate differ from other Kyokushin karate branches?" I consider this question crucial enough to clarify thoroughly. In reality, several organizations manage their own networks today, including IKO1, IKO Matsushima, Kyokushin-kan, and WKO Shinkyokushinkai led by Kenji Midori (which my family and I currently train under). Frankly speaking, all of these organizations feature exceptional masters who have contributed immensely to the martial arts world. Choosing an affiliation is therefore a matter of suitability for each family's goals rather than a question of good versus bad.

The most significant difference in my view is not merely organizational names or chest emblems, but "international support systems" and "world-class competition standards." Having attended seminars and tournaments across multiple organizations, I have observed that WKO Shinkyokushinkai holds a distinct advantage in network scale, dojos spanning over 100 countries, and professional tournaments offering the highest prize money in full-contact karate. Furthermore, WKO Shinkyokushinkai's black belt certification and instructor auditing systems are transparent and strict to the degree that I am confident that when my students earn a black belt, they will receive true international recognition. Every black belt issued through IMAC Dojo is certified and registered with Japan HQ through Karate Shinkyokushin Thailand's legitimate chain of command, without shortcuts or arbitrary individual instructor discretion.

I often explain to parents in simple terms that choosing a dojo shouldn't be based on grand-sounding names or attractive chest logos, but on the "chain of command"—how the instructor connects with global governing bodies, who certifies them, and whether ongoing quality control exists. In Thailand, numerous karate schools use words like "Kyokushin" or "Full Contact" in advertising without formal links to Japan HQ. While this does not mean those schools teach poorly, parents should have complete information before deciding, ensuring their children receive full value for their dedicated time and effort.

Kenji Midori is president of WKO Shinkyokushinkai, whose official message frames its work around youth development, social contribution, and international exchange.

This article therefore focuses on the leadership role verifiable through WKO. A fuller biography and competition history appear in the site's dedicated Shinkyokushinkai history article.

WKO's leadership transition took place through several stages after Mas Oyama's death and the later restructuring of the organisation. Rather than relying on secondary timelines, this article uses WKO's current identification of Kenji Midori as president.

For a student in Thailand, the more practical questions are which standards the class follows, who teaches it, and whether the grading path can be explained clearly.

Many who consult me at IMAC Dojo ask how Shinkyokushin Karate fighting techniques differ from karate seen in movies or WKF Olympic karate. I explain through three simple pillars: Kumite (full-contact fighting), Kihon (basics practiced thousands of times until becoming automatic physical reactions), and Kata (preset forms embedding fighting philosophy in every movement).

What sets Shinkyokushin Karate apart most clearly is its full-contact ruleset, which permits fighters to use full impact when kicking and striking the body with hands, as well as kicking to the head, while straight punches to the face remain prohibited under traditional rules. I view this as a clever balance: it requires fighters to develop powerful kicks and body strikes rather than light point-touches, while preserving head safety to prevent excessive severe injuries for everyday students not aiming for professional competition.

Technically, I teach my students that Shinkyokushin Karate heavily prioritizes solid stances, especially Kiba Dachi (horse stance), which must be trained until legs are strong enough to absorb impacts without losing balance. In real combat, if your stance is unstable, even beautiful offensive techniques are useless, as opponents can easily push or kick you off balance. Furthermore, Mawashi Geri (roundhouse kick using hip rotation for power) and Mae Geri (front kick emphasizing piercing speed) are core techniques students practice repeatedly until body memory takes over without conscious thought.

What I emphasize especially is that Shinkyokushin Karate training is not just physical strengthening, but training the mind to remain calm under pressure. I have seen children who initially cried from fear of contact in early weeks undergo remarkable transformations over months. Former fear is replaced by confidence—not because they no longer feel pain, but because they learned to navigate that sensation mindfully. This is the "true gift" of Shinkyokushin Karate: in a world where youth grow up amidst modern comforts, full-contact karate provides a safe space to learn that difficulty is not something to flee from, but something to master.

Beginners entering martial arts often ask how to start Shinkyokushin Karate training. I answer truthfully: there are no shortcuts. Everyone—whether a five-year-old child or a middle-aged beginner—undergoes the same process: repeatedly practicing Kihon (basics) until body memory takes over. In early weeks, I do not rush into complex sparring techniques; I focus first on stances, breathing, and dojo etiquette. Without solid physical and mental foundations, teaching advanced techniques is useless and risks unnecessary injuries.

The first step every new student learns is the bow, or Rei, before entering and leaving the training area. This is not a meaningless ritual, but a mental exercise in respecting the facility, the instructor, and fellow practitioners. Afterward, I introduce foundational stances like Zenkutsu Dachi (front stance) and Kiba Dachi (horse stance). New students often complain of leg soreness in early weeks, but I tell them this fatigue is the sign that their bodies are adapting and building new strength.

Once stances stabilize, I gradually introduce basic punching and kicking techniques, starting with straight punches, followed by front kicks, progressively advancing according to individual progress. I always remind parents never to compare their child's progress with peers in the same class: physical and mental development occurs at individual paces. Some excel in physical strength early on but take longer to master timing and emotional control, while others learn techniques slowly at first but exhibit superior long-term discipline and endurance.

After three to six months of consistent training, I introduce light Kumite, known as Yakusoku Kumite (pre-arranged sparring), allowing students to adapt to distance and contact timing before progressing to controlled free sparring based on readiness. I never rush any student into full-contact sparring before comprehensive evaluation by myself and dojo assistant instructors. Full contact too early with weak basics risks injuries and shatters confidence. Proper karate instruction is like growing a tree, not assembling a prefabricated building: we must water, fertilize, and ensure strong roots before letting the tree face real storms.

I have noticed a clear shift over the past decade in Bangkok parents' attitudes toward choosing extracurricular activities for their children. Previously, most parents favored gentle, non-contact activities. Today, many recognize that allowing children to face controlled challenges under responsible instructors is essential for developing mental resilience in an uncertain world.

One reason parents frequently cite at IMAC Dojo is concern over school bullying. Parents share that their children were teased about body shape, pushed on playgrounds, or verbally intimidated until afraid to go to school. I explain to parents that full-contact karate does not teach children to be aggressive or violent. On the contrary, it builds physical confidence and self-defense capability if ever necessary. This self-assurance often prevents children from becoming targets in the first place, as bullies typically target those who appear weak and insecure.

Another vital aspect is focus and discipline. In an era of smartphones and instant gratification, many children arriving at my dojo struggle with attention spans and perseverance. Practicing Kihon hundreds or thousands of times serves as an extraordinarily powerful focus tool. Children learn to sit with the repetition until movements become automatic. Perseverance built in the dojo translates into other areas of life, such as academics or long-term projects requiring sustained effort.

As a father who experienced this firsthand with four children, I advise hesitant parents: do not make the decision for your child immediately. Bring them to experience the dojo atmosphere firsthand. Let them see other kids train, hear commands shouted, smell the sweat and determination in the air, and ask how they feel. No matter how much parents want their child to be strong, without internal motivation, forced training yields no lasting results.

Karate Shinkyokushin Bangkok exists in several training contexts. Families should compare location, schedule, class size, beginner supervision, and affiliation instead of deciding from the words Full Contact alone.

IMAC Dojo uses Shinkyokushin Karate Ladprao 101 to describe its service area and trains within WKO Thailand Branch standards under Shihan Fumiaki Frank Nagashima.

Current options start from THB 800 across defined group and private formats. Check the Course page for the latest schedule, fees, and conditions before travelling.

Full-contact training involves real contact and therefore risk. No school should guarantee an injury-free outcome; suitability depends on experience, age, health, partner matching, and instructor control.

An appropriate beginner class should establish stance, movement, kihon, distance control, and structured partner drills before increasing the force or uncertainty of kumite.

Parents should ask whether a child may rest or decline a partner, how instructors respond to pain, and how general classes differ from competition preparation. Anyone with a previous injury should seek appropriate professional advice.

Looking back on the path from sitting beside the mat watching my sweat-stained children catch their breath in their Gis to standing as founder of my own dojo, I understand deeply that Shinkyokushin Karate is not just about teaching people to kick and punch better. It is a mindset system molding individuals to recognize their limits and overcome them step by step through discipline. The history of organizational transition, branch chief unification, and generational hand-offs leading to the Midori era demonstrates that all great institutions undergo trials before building lasting strength.

What I have held true throughout my years of practice and teaching is that the true value of Shinkyokushin Karate lies not in organizational leaders or handed-down stories, but in the moment a student stands before the mirror practicing Kihon for the hundredth time until movement becomes effortless, or when a child once crying from contact stands tall and fights on the following week. That is the unchanging essence of this art.

As founder of IMAC Dojo and a father who traveled this path alongside my wife and four children, I invite anyone hesitating—for themselves or their children—to step into a dojo and experience real training. No words can replace standing on the mat, hearing commands, smelling determination, and discovering physical and mental strength you never knew you possessed. That is the gift Shinkyokushin Karate has given my family, and it is what I wish to pass on to everyone ready to step into this world with an open heart and genuine determination.
