The kanji (Japanese characters) calligraphy, worn universally on the front of the gi, simply means "Kyokushinkai", which is the name given by Sosai Mas Oyama to the karate style he created. It is composed of three characters:
Kyoku meaning "Ultimate".
Shin meaning "Truth" or "Reality".
Kai meaning "Society" or "Association".
The symbol of Kyokushin Karate is the Kanku, which is derived from Kanku Kata, the Sky Gazing Form. In this kata, the hands are raised and the fingers meet to form an opening through which the sky is viewed. The top and bottom points of the Kanku represent the first fingers of each hand touching at the top and the thumbs touching at the bottom, symbolizing the peaks or ultimate points. The thick sections at the sides represent the wrists, symbolizing power. The center circle represents the opening between the hands through which the sky is viewed, symbolizing infinite depth. The whole Kanku is enclosed by a circle, symbolizing continuity and circular action.
