Kyokushin One – Global Dan Grade

Verification & Registration

Kyokushin One is not just another organization — it is the first global Kyokushin Dan grade verification and registration platform.

In a world where new federations, self-appointed grades, and unofficial certificates are increasing, Kyokushin One offers transparency, recognition, and unity. Our goal is to bring legitimacy back to what truly matters: your path, your history, and your authentic achievements in Kyokushin Karate.

Why Register with Kyokushin One?

We provide an international register for verified dan grades. Anyone can claim a black belt — but having your dan grade registered in an independent, globally accessible database offers real value, trust, and recognition.

Before listing any dan grade, we always perform a thorough verification, ensuring authenticity and integrity.

We currently recognize dan grades issued by the following major Kyokushin organizations:

• IKO1 (Matsui)

• WKO (Shinkyokushinkai)

• IKO Sosai / Kyokushinkaikan (Royama)

• IFK – International Federation of Karate

• KWU – Kyokushin World Union

• KWF – Kyokushin World Federation

• IKO Matsushima

• IKO Nakamura (WFKO)

• So-Kyokushin (Adachi)

• WKB – World Kyokushin Budokai

• Zen Kyokushin – International Karate Organization

Not listed above?

If your dan grade was issued by a smaller or independent organization, you may still apply. We will conduct a detailed review, including your training history, the organization or individual who awarded the grade, and your current role in the Kyokushin community.

Join the Movement

By registering your dan grade with Kyokushin One, you show your students, peers, and the world that your rank is earned, verified, and respected.
