Green belt is not only the time to refine all previous technique and kata, its the time to start really developing your practical application of all techniques, stances and kata. While this is happening all the time for a karate-ka, from White belt through to Orange belt our goal is predominantly on forging a weapon and turning it into subconscious competence – in other words, to do it competently without having to think about it.
Green belt is when we can really start to think about applying what we know and putting it into practise. Do take note however that that this is an exciting life long journey.
Having spent ample time learning and developing the first three kata, a Green belt can take the time to learn and develop their bunkai knowledge and ability, and also to put the principles promoted in these kata into their kumite.
