In "Cobra Kai", Miyagi is revealed to have died on November 15, 2011, at the age of 86. He frequently appears in flashbacks using clips from the first 3 movies. Among other details, his gravestone lists him as a member of the famed Japanese-American 442nd Regiment along with a Combat Service Identification Badge and a Medal of Honor. Alongside the marker is a bonsai tree. Daniel regularly comes to visit the grave and trim the bonsai; he considers "a few months" to be a long time between visits. Miyagi's legacy continues to play a role in Daniel's life, as he seeks to regain balance in his life by taking up karate once again after a lengthy period of not training and becoming a mentor to Robby Keene (Johnny Lawrence's estranged son), trying to turn his protege's life around as Miyagi had done for him. In one scene, Daniel LaRusso says one of the last things Mr. Miyagi built for the Miyagi-do was a balance board for Bonsai which LaRusso uses to train his students in karate.
