Global Kyokushin Budokai (GKB) is an international martial arts community founded by Dr. István Adámy, 9th dan karate master and a direct student of Mas Oyama. Our aim is to preserve Mas Oyama's legacy and to deepen and pass on the knowledge of Kyokushin, in the unity of physical, mental and spiritual development.
We offer international professional contacts, joint training, seminars and tournaments. Our growing, multilingual digital knowledge base brings together the knowledge of karate, throws, groundwork and self-defence in books and instructional videos.
There are three ways to join us: as a full member, as a partner member or as an interested learner. Join us!
