Kaicho Hatsuo Royama 1948-2026

Kyokushin has lost one of its most important remaining links to the years in which our karate was still being formed.

Kaicho Hatsuo Royama, founder of Kyokushin-kan, passed away on August 3, 2026, at the age of 78. According to the announcement from Kyokushin-kan, he had been battling illness for some time when his condition suddenly worsened. He passed away at 4:48 that afternoon.

Royama’s place in Kyokushin history extends well beyond his record as a tournament fighter. His life connected the original Oyama Dojo, the early development of Kyokushin, the first generation of open-weight competition and the many changes that followed Sosai Mas Oyama’s death. He began training before the International Karate Organization Kyokushinkaikan was formally established and remained an important figure in the wider Kyokushin world for more than six decades.

Hatsuo Royama was born on March 31, 1948, in Gyoda, Saitama Prefecture. In the autumn of 1963, during his first year of high school, he entered Mas Oyama’s dojo in Ikebukuro. The International Karate Organization Kyokushinkaikan would be formally established the following year, placing Royama among the generation that trained while Kyokushin itself was still taking shape. Among those already training under Oyama when Royama entered the dojo was Steve Arneil, who had begun his own training there in January 1961. Their years under Sosai overlapped, and Royama was part of the Oyama Dojo during the period when Arneil completed the 100-man kumite in May 1965. Almost five decades later, the two men would work together again as founding leaders of the Kyokushin World Union.

It is easy to look back at the men who emerged from the early Oyama Dojo and imagine that they were somehow destined to become great karateka. Royama’s own development was not nearly so straightforward. Although he became an instructor at Honbu, he also reached a point where he was dissatisfied with his own ability and understanding. Rather than remain comfortable with the position he had attained, he left Kyokushin for a time and searched elsewhere for what he believed he was missing.

Royama explored other forms of fighting, received instruction from Kenichi Sawai, founder of Taikiken, and spent several years training under Hideo Nakamura. The influence of that period remained evident throughout the rest of his life. His later teaching reflected a continuing interest in posture, distance, natural movement and the generation of power, all of which became part of the karateka he was when he eventually returned to Kyokushin.

There is something worth remembering in that part of his story. Royama had already trained at Honbu and had served as an instructor, yet he was willing to acknowledge that there were things he did not understand and weaknesses he had not overcome. He could have remained where he was and relied upon the position he had earned, but instead returned to the role of a student and spent years rebuilding his karate. The path he followed was not a rejection of what he had learned under Oyama. It became part of his effort to understand it more deeply.

When Royama returned to Kyokushin, the results of that training became increasingly apparent. In 1973, he entered the Fifth All Japan Open Karate Championship and won the tournament, becoming the fifth All Japan champion. Two years later, Royama competed in the inaugural World Open Karate Championship. The tournament was fought under open-weight rules, placing smaller fighters against opponents who sometimes held a considerable advantage in size. Royama’s victory over the much larger American Charles Martin became one of the enduring matches of that first World Tournament.

Royama repeatedly attacked Martin’s legs, gradually taking away his ability to stand and fight effectively. The match became an early and widely seen example of how a well-developed technique, applied with timing and consistency, could overcome a substantial difference in size. Royama continued to the final, where he faced Katsuaki Sato. The decision went to Sato, leaving Royama as runner-up in the first Kyokushin World Open Tournament.

Royama became closely associated with the gedan mawashi geri. He did not invent the low roundhouse kick, but his use of it helped demonstrate its effectiveness and contributed to its place as one of the characteristic weapons of Kyokushin fighting.

The success of his low kick was not simply a matter of striking hard. It depended upon his ability to control the distance, maintain his own position and continue attacking the same area without losing his balance or composure. His crescent kick, direct punching and ability to remain calm in front of larger opponents were also important parts of his fighting, but the low kick became the technique most closely identified with his name.

For many karateka outside Japan, the surviving footage from the 1975 World Tournament was their introduction to Royama. What they saw was a comparatively small fighter who appeared neither hurried nor intimidated by men who were considerably larger. He did not attempt to fight according to their physical advantages. He relied upon the karate he had spent years developing.

His tournament accomplishments would have been enough to secure his place in Kyokushin history, but competition was only one part of his contribution. Royama continued to study and examine karate long after his competitive career ended. The influence of Taikiken remained visible in his teaching, along with his interest in posture, breathing, movement and the ability to generate power without unnecessary tension.

Following Sosai Oyama’s death in 1994, Royama served as chief adviser and chief instructor within the Kyokushinkaikan organization led by Shokei Matsui. He remained there until 2002, when he departed and established Kyokushin-kan. The new organization formally began on January 13, 2003.

The organization Royama founded reflected the range of his own martial arts experience. Its training included kihon, kata, kumite and kata application, along with traditional weapons, makiwara and sandbag training and methods influenced by Iken. These were areas he had explored during his own development and chose to emphasize in the organization he created.

None of those areas of training belongs exclusively to one branch of Kyokushin, nor should Royama’s interest in them be interpreted as a judgment upon the training followed elsewhere. Their importance to his story is that they reflected the particular path he had taken and the influence of the teachers and experiences that shaped his karate.

Royama also participated in one of the more notable efforts to encourage cooperation across the organizational divisions within Kyokushin. On October 12, 2011, representatives of Kyokushin-kan, the International Federation of Karate, the Kyokushin World Federation and the Association of Kyokushinkai of Russia met in Moscow for the founding conference of the Kyokushin World Union. Royama, Hanshi Steve Arneil, Shihan Loek Hollander and Ramil Gabbasov signed the statute of the new organization.

For Royama and Arneil, the occasion brought together two men whose association reached back to the Oyama Dojo of the early 1960s. Almost five decades after their years under Sosai, they were among the senior leaders attempting to create opportunities for karateka from different branches of Kyokushin to train and compete together. The organizations involved remained independent, retaining their own leadership, curriculum and identity. Their cooperation nevertheless demonstrated that senior figures who had followed different organizational paths could still find areas in which they were able to work together. Photographs of Royama and Hanshi Arneil together carry particular meaning because their shared history began long before either Kyokushin-kan or the IFK existed.

Another photograph accompanying this article shows Royama with Shihan Michael Monaco taken during a summer camp in Japan while Sosai was still living. Shihan Monaco founded USA-IFK under the guidance of Hanshi Arneil and today holds the rank of 8th dan in the IFK. Royama and Monaco followed different organizational paths, but both became senior figures within branches that trace their history to the Kyokushin created by Sosai Oyama. Their photograph is a reminder that the wider Kyokushin world has never been defined solely by organizational boundaries.

In April 2022, Hiroto Okazaki, Royama’s longtime student and first uchi-deshi, was appointed the second Kancho of Kyokushin-kan. Royama continued as Kaicho and founder, allowing the active leadership of the organization to pass to another generation while he remained its senior figure.

In 2024, Black Belt Magazine inducted Royama into its Hall of Fame with a Lifetime Achievement Award. The recognition reflected not only his competitive record, but also his decades as a teacher, author and international representative of Kyokushin karate.

It would be understandable to remember Royama primarily through the footage of the first World Tournament. His match with Charles Martin and the low kicks that made him famous will remain part of Kyokushin history, but his importance reaches beyond a single tournament or technique.

Royama belonged to a generation that knew Kyokushin before the International Karate Organization Kyokushinkaikan had been formally established, before the first World Tournament and before the organizational divisions that followed Sosai Oyama’s death. He could speak about the Oyama Dojo not as a period he had studied, but as a place where he had trained.

As that generation passes, Kyokushin loses more than celebrated competitors and senior instructors. We lose people who carried personal memories of the circumstances in which our karate developed. The responsibility for preserving those experiences now rests with the students they taught, the books and recordings they left behind and the karate practiced by the generations that follow.

Royama’s influence will remain visible in the low kick that became such an important part of Kyokushin fighting. His teaching will continue through Kyokushin-kan and through the many karateka influenced by his approach. His life also provides an example of someone who, even after becoming an instructor, was willing to admit that he had not yet found the strength or understanding he sought.

He responded by continuing to train, seeking instruction beyond what he already knew and eventually returning with a deeper understanding of his own karate. That willingness to remain a student throughout his life is as much a part of his legacy as his victories in competition.

Kaicho Hatsuo Royama leaves an important legacy throughout the wider Kyokushin world. We may belong to different organizations and may not always agree about tournament rules, curriculum or the direction Kyokushin should take, but his place in our shared history should be recognized by all of us.

We extend our sincere condolences to his family, his students, the members of Kyokushin-kan and all those whose lives were touched by his teaching and example. The loss will be felt far beyond the organization he founded

May he rest in peace.

Osu.
