The Kyokushin Karate 極 真 空手 or KyokushinKai Karate 極 真 会 空手 is a modern form of karate developed by the original Korean Grandmaster Masutatsu Oyama (大 山 倍 達 Oyama Masutatsu).
Kyokushinkai, a school founded in 1953, was nothing more than a grass field at Meijiro in Tokyo at the time. The Kyokushinkai Karate has been officially known as the hardest form of Full Contact Karate since the first world championships in 1975 worldwide.
Masutatsu Oyama (1923-1994) developed the Kyokushinkai Karate mainly from the Shotokan Karate and GojuKai Karate. Mas.Oyama trained Shotokan Karate at Gishin Funakoshi & Goju Kai Karate at Gogen Yamagushi.
The Kyokushin Karate devotes a lot of attention to Kumite (spruce or match-Karate) and has a wide range of Kata's (established exercises).
