Mas Oyama features Masatutsu Oyama, the founder of Kyokushin Kai Karate. He is shown performing his famous bull fighting routine where he actually chops the horn off a bull. Also you will see the demonstration where he chops the top off of a bottle. You will see Oyama weight training and performing Naihanchi Kata. Oyama Sensei is seen training on the Makiwara in a severe manner. Much of this film we believe had been lost until this point in time and we are certain that anyone who appreciates the strength and power of one of the strongest karate ka’s the world has ever seen, will appreciate this DVD. It appears that some of this film was actually done in the ’30s or early ’40s. Key Words: Kyokushin Kai, Japanese Karate, Oyama, demonstration
