Masutatsu Oyama Trilogy

Sonny Chiba plays Kyokushin Karate founder Masutatsu Oyama, who unexpectedly arrives at a karate tournament in rags, but wins the tournament. After turning down the chance to fight at future tournaments he returns to his simple village life. He reluctantly returns to karate for a final showdown against the students of a rival school.

Masutatsu Oyama is recruited by his former Army friend to work for a crew of gangsters, but when they kill both his girlfriend and his best friend, Oyama flees away to a small town where he both learns lessons in martial arts philosophy from a wandering master and helps a young boy take on a challenge to fight a ferocious captured bear to win money for the boy's injured father.

The last of the Masutatsu Oyama trilogy. Oyama takes a job as a professional wrestler in Okinawa, but when he discovers that he is expected to take a dive, he quits in disgust. However, when a friend finds herself in desperate need of medical supplies, Oyama steps back in the ring to raise the money—but will he be able to follow the script this time?
