After the death of Masutatsu Oyama in April 1994, unified Kyokushin split into dozens of independent organizations. Today the world has more than 120 federations and organizations developing Kyokushin — each with its own rules, leadership, and competition system. Together they unite somewhere between 12 and 15 million practitioners across more than 130 countries.
Why Kyokushin Split
Masutatsu Oyama left no official will naming a successor. This triggered a sharp conflict: several powerful masters competed for control of the international organization IKO, which Oyama himself had founded in 1964. The first major split actually occurred during the founder’s lifetime in the late 1980s and early 1990s, when a number of prominent masters left IKO and created their own structures. After Oyama’s death the process accelerated: different groups lost the restraining authority of the founder and each went its own way.
Fragmentation is not only a weakness. Each organization brings something of its own: WKO emphasizes competition across 101 countries, IFK preserves the spirit of original Kyokushin as envisioned by Oyama, Kyokushin-kan develops traditional kata, and KWU unites several leading organizations under a single competitive umbrella.

Kyokushin Association of Russia (AKR)
The Kyokushin Association of Russia (AKR) is a special body in Russian Kyokushin created to coordinate and unite all national federations.
History
AKR received state accreditation on March 19, 2004 as the sole Russian Ministry of Sport-recognized all-Russian organization developing Kyokushin. The organization was created out of the need for a single official representative of Kyokushin before government bodies and at international sports forums.
In December 2005, the Federation of Kyokushin-Kan Karate-Do of Russia and the Federation of Kyokushin Russia (WKO) were officially admitted to the Association. This was the first step toward uniting disparate organizations under a single umbrella.
In 2011, the AKR Presidium was established. It develops the strategy for Kyokushin in Russia, makes decisions on regional activity, and coordinates international relations.
Membership: Who Is in AKR
Today the Kyokushin Association of Russia includes five federations:
- FKKR (WKO) — Kyokushin Karate Federation of Russia, affiliated with WKO Shinkyokushinkai of Kenji Midori
- FKKR (KI) — Federation of Kyokushin-Kan Karate-Do of Russia, affiliated with Kyokushin-Kan International of Hatsuo Royama
- RNFKK (IKO) — Russian National Federation of Oyama Kyokushinkai Karate-Do, affiliated with IKO Matsui
- FKR (IKO) — Federation of Kyokushinkaikan Russia (second organization in the IKO system)
- FKR (IFK) — Kyokushin Federation of Russia, affiliated with Steve Arneil’s IFK
President and Leadership
The President of the Kyokushin Association of Russia is Yuri Petrovich Trutnev — a statesman and holder of a 5th dan in Kyokushin. Trutnev has served at various times as Mayor of Perm, Governor of the Perm Krai, and Minister of Natural Resources of the Russian Federation. His authority played a major role in securing AKR’s official recognition at the state level.
The Executive Director of AKR is Sergei Gennadyevich Suvorov.
Purpose of AKR
The Association’s primary goal is to overcome the fragmentation of Kyokushin in Russia and present a unified face of Kyokushin to the state and the international community. Thanks to AKR:
- Kyokushin gained the status of an officially recognized sport in Russia
- It became possible to award official sports titles (Candidate Master of Sport, Master of Sport)
- Russian athletes can compete at all-Russian competitions under a unified banner regardless of their individual federation
- Kyokushin gained the ability to participate in international multi-sport events with state support
Conclusion: Why There Are So Many Organizations
The fragmentation of Kyokushin is the inevitable consequence of the death of a charismatic founder without a clear succession mechanism. Over the 30 years since Oyama’s passing, the situation has stabilized: the major organizations have built their own championships, belt systems, and communities. The creation of KWU in 2011 was an attempt to establish a supra-organization for joint competition without merging.
For the practicing karateka, the variety of organizations is not a problem: technique, philosophy, and the spirit of OSU are the same across all branches. Differences mainly concern competition rules and belt systems. When choosing a club, what matters most is the quality of the coach and the training process — not the flag above the door.
