If you look closely at your SSKA badge roundel (Inyo) you'll notice there is a similarity between it and the symbols used on the Okinawan national flags both (old and new).
The main component is a red disk on a white background which is raised higher than the centre of the white disk, representing the rising sun. Similar to
that of the Japanese national flag. The flag is made up of a white letter O in a red disc on a white field. The O is the prefecture initial letter. The inner small red disc stands for progress of Okinawa and the red circle for the sea surrounding Okinawa.
It is also reminiscent or similar to the Japanese flag which has the symbol of the rising sun, and is symbolic of hope a new beginning. The white of the flag represents honesty and purity and the red stands for sincerity and passion.
Yin Yang
This is the ancient Chinese symbol of Yin &Yang representing two opposing but complimentary principles found in all objects & processes in the universe. i.e. Hard & soft, fast & slow, good & evil, light & dark, male & female.
This Symbol (Yin -Yang) represents the ancient Chinese understanding of how things work. The outer circle represents "everything", while the black and white shapes within the circle represent the interaction of two energies, called "yin" (black) and "yang" (white), which cause everything to happen. They are not completely black or white, just as things in life are not completely black or white, and they cannot exist without each other.While "yin" would be dark, passive, downward, cold, contracting, and weak, "yang" would be bright, active, upward, hot, expanding, and strong. The shape of the yin and yang sections of the symbol, actually gives you a sense of the continual movement of these two energies, yin to yang and yang to yin, causing everything to happen: just as things expand and contract, and temperature changes from hot to cold.
In martial arts & karate in particular it represents balance of body, mind & spirit.
