The Karyukai Association symbol contains a combination of specific geometric shapes. The meaning of the ideographs inside the rhombus is KORYU, meaning “ancient martial arts”; behind the rhombus we have the symbol of the Ryogen Ryu school, a circle and a square in the center (with diagonals), which can be read by juxtaposing and rotating the letters O, N or Z, ONO or OZON. The other three ideographs represent KA – Fire, RYU – Dragon, and KAI – Association, therefore The Association of the Fire Dragon, Fire Dragon being the martial arts name of Ozon Karyu sensei, name which was given by Soke Takashi Ono in March 1998.
