Hello Hun san. I'm Yuki as a tutor here. I used to learn Karate when I was in junior high school so I might be able to help you with it but what would you like to know about? I don't think there are that much of special words about it. Also my type of karate ( ryuha ) was "Okinawa goujyuryu" which is not kyokushin karate ( written as 極真空手. ) I don't know if the other types of karate has other words or different words for it or not. I might be able to help you with my lesson if that's what you are looking for.
