Question: does mr miyagi die in karate kid 3

Answer: No, At the tournament, Barnes reaches the final round to challenge Daniel. Silver and Kreese instruct Barnes to inflict serious damage on Daniel, keep the score a tie, and finally beat him in the sudden death round. Barnes gets the upper hand during the fight while taunting Daniel relentlessly. When the initial round concludes, Daniel wants to concede, but Miyagi urges him on. In the sudden death round, Daniel performs the kata; as a confused Barnes lunges toward him, Daniel flips him to the ground and strikes him to win the tournament. Silver walks away in disgrace while the crowd throws their Cobra Kai shirts back at him. Because of Silver, Kreese, and Barnes's actions, the Cobra Kai was issued a lifetime ban from competing in the All Valley tournament.
