Kyokushin karate is recognized around the world by its distinctive symbols, particularly the traditional Kyokushinkai kanji and Kanku. These symbols remain widely used throughout Kyokushin today, both by major organizations and independent dojos. As Kyokushin developed into different organizations, some retained the traditional symbols while others adopted variations or distinctive emblems of their own. This page looks at the traditional symbols of Kyokushin, along with those associated with the International Federation of Karate (IFK), World Karate Organization Shinkyokushinkai (WKO), and Kyokushin-kan.
Kyokushinkai Kanji (極真会)

The kanji (漢字) worn on the left chest of the gi is a stylized brush calligraphy that reads “Kyokushinkai” (極真会), the name given by Sosai Mas Oyama to the karate style he founded. It is composed of three characters:
- 極 (Kyoku) – Ultimate
- 真 (Shin) – Truth
- 会 (Kai) – Association
Together, Kyokushinkai (極真会) means “The Association of the Ultimate Truth.” The kanji reflects the pursuit of personal truth through rigorous training and discipline.
Kanku Symbol (観空)

The Kanku is the emblem of Kyokushin and originates from the kata Kanku Dai (観空大), meaning “View the Sky.” In the kata, the hands are raised, and the fingers form a diamond-shaped window through which the sky is viewed.
- The points at the top and bottom of the symbol represent the fingertips — symbolizing peak focus.
- The thicker sides represent the wrists — symbolizing strength and power.
- The open center circle represents the view through the hands — symbolizing infinite depth.
- The outer circle enclosing the shape symbolizes continuity and circular motion.
- This symbol expresses the core values of Kyokushin: strength, clarity, and infinite potential, all encircled by the never-ending path of improvement.
IFK Emblem

The International Federation of Karate (IFK) crest, worn on the upper right sleeve of the gi, features a rising wave drawn from the kata Saiha (最破), meaning “maximum break” or “smashing through.” The wave represents:
- Persistence in the face of adversity
- Rising above challenges with patience and spirit
- The essence of Osu no Seishin (押忍の精神) — the Spirit of Osu
Shinkyokushinkai Kanji (新極真会)

The Shinkyokushinkai kanji (新極真会) is a variation of the traditional Kyokushinkai kanji used by the World Karate Organization Shinkyokushinkai (WKO). It retains 極真会 (Kyokushinkai) while adding 新 (Shin), meaning “new,” giving the name Shinkyokushinkai — “New Kyokushinkai.” The calligraphic design maintains a clear visual connection to the traditional Kyokushin kanji while distinguishing Shinkyokushinkai as a separate organization.
WKO Shinkyokushinkai Emblem (世界空手道連盟新極真会)

The World Karate Organization Shinkyokushinkai (WKO) emblem is a distinctive red circular symbol used to represent Shinkyokushinkai internationally. Its flowing circular design visually distinguishes the organization from the traditional Kyokushin Kanku while maintaining a recognizable connection to the Kyokushin tradition.
Kyokushin-kan Kanji (極真館)

The Kyokushin-kan kanji (極真館) is used by the Kyokushin-kan International Karate Organization, founded by Hatsuo Royama in 2002. It retains 極真 (Kyokushin) — “Ultimate Truth” — while replacing the traditional 会 (Kai), meaning “association,” with 館 (Kan), meaning “hall” or “training institution.” The calligraphy preserves a strong visual connection to traditional Kyokushin while identifying Kyokushin-kan as a distinct branch of the Kyokushin tradition.
