I train in kyokushin(IKO1), and the style fits me well. The reason why i chose kyokushin out of all the karates out htere was simple, at that time i didnt know well about karate so i just chose the very popular kyokushin. I was watching k-1 on tv, and saw andy, filho they are from kyokushin, so that was my reason to choose kyokushin. THe full contact rule is great and fun. One bad thing which I dont like is that kyokushin is split to 2, they are IKO1 and IKO2. WHen Mas. Oyama passed away, Matsui became the head of the kyokushin ORG, however some people didnt like new Kancho(Matsui) being young so they left kyokushin to make a new kyokushin, its called "Shin-kyokushin", its also known as IKO2(International Kyokushin ORG 2) founded by Kenji Midori who won the IKO1 the 5th world open kyokushin karate tournament. I personally think this shouldnt have occured, even if Midori didnt like Matsui but Matsui is the one chosen by Mas. Oyama, so Midori should have accepted that fact. In the old kyokushin days, they invited all sort of fighters in the world open karate tournament. kung-fu, muay thai etc.. now they dont invite them i think.. it would be interesting to invite some thai fighters thou. For the latest 8th world tournament, they invited some fighters from Seidokan Karate thou.
