Hello all! It has been many years since I've posted something here. Anyways, I found a website in which bunkai for Kyokushin kata is explained. The website is by Howard Collins who appeared in the movie "Fighting Black Kings/Shijo Saikyo no Karate", a movie about the first Kyokushin world tournament. He used to represent the UK branch. Here is a link to the page containing the bunkai:
The bunkai herein is for kata that are well known outside Kyokushin (Kanku, Seienchin, Pinan/Heian, basic blocks, Saiha). I hope there will be some videos for kata exclusive to Kyokushin (Tsuki no kata, Yantsu, Garyu, Gekisai Sho) or katas that have been modified beyond recongnition in Kyokushin (Seipai, Sushiho/Gojushiho).
By the way, is Howard Collins Shihan still famous in the UK?
