Mr. Miyagi's Secret Necklace Explained: What It Means For Cobra Kai & Karate Kid

Warning! This article contains spoilers for Cobra Kai season 6, part 3.

Cobra Kai season 6, part 3 finally answers the mysteries that were linked to Mr. Miyagi. Cobra Kai season 6's story has followed a similar trend to its predecessors by balancing the storyline of characters like Johnny, Daniel, and their students with developments about the late Mr. Miyagi. Miyagi's legacy is even set to be developed further in the story of Karate Kid: Legends, yet Cobra Kai season 6 first had a lot of mysteries it needed to answer about the sensei's shrouded past.

Not only did these mysteries link Miyagi to Cobra Kai's Sekai Taikai, but they also centered around the seeming arrest of Daniel's mentor earlier in his life. With Cobra Kai season 6, part 3 bringing the show to an end, these answers were provided. Cobra Kai's cast of characters finally got to the bottom of the Miyagi mystery, with the answer being hidden in plain sight the entire time. With that said, here is Mr. Miyagi's long-kept secret, the answers Cobra Kai season 6, part 3 gives, and how they help to wrap up the story of the show’s characters.

The mystery in question links back to the box Daniel, Amanda, and Chozen found in Cobra Kai season 6's first part beneath the floorboards of Miyagi's dojo. The box included a newspaper clipping that mentioned an assault and the theft of a valuable necklace, with the reveal throwing Daniel off balance. However, Cobra Kai season 6, part 3 revealed the history of the necklace, explaining that it was an heirloom of the Miyagi family. The necklace belonged to Mr. Miyagi's mother, with his father granting it to him after he decided to move to the United States.

The necklace was given to Miyagi in case he needed to sell it in order to earn some money upon emigrating. Miyagi kept the necklace, instead deciding to give it to his wife. During World War II, Miyagi's wife was taken to an internment camp for Japanese-Americans while he fought in Europe. This led to the necklace being stolen by a guard at the camp, robbing the Miyagi family of their heirloom and prompting the next stage of the mystery, which links back to Daniel's discovery from Cobra Kai season 6, part 1.

As alluded to, this reveal in Cobra Kai season 6, part 3 links to Daniel's discovery of the newspaper clipping that mentions an assault and theft on Miyagi's part. As the story of the necklace is revealed to Daniel and Amanda, they begin to fill in the blanks of the story. Rather than hold on to their assumption that Miyagi simply assaulted someone and stole their belongings, they quickly realize that Miyagi was simply taking back what was once his. As revealed in the first Karate Kid movie, while his wife was in the internment camp, Miyagi was away fighting in Europe.

Upon his return, he received news that his wife and son had died in the camp, with Cobra Kai season 6, part 3 retconning this further. The show reveals that Miyagi also realized his family's necklace had been taken from his wife at the time, prompting him down a path of justice to find it. Herein lies the explanation for the newspaper clipping; Miyagi tracked down the guard who stole the necklace and took it back, with the aforementioned "assault" being a result of Miyagi defending himself from the guard's attacks.

Daniel LaRusso’s Mom Had The Answer To The Mr. Miyagi Mystery The Whole Time

The Answer Was Close To Home

Regarding how these answers were discovered in Cobra Kai season 6, part 3, they were divulged by another member of the Karate Kid universe who had a strong connection to Mr. Miyagi: Daniel LaRusso's mother. Randee Heller returns in Cobra Kai season 6, part 3 as Lucille LaRusso, with the family gathering for a meal in the show's final episode. During the meal, Lucille reveals that she has the necklace, prompting her to explain the entire story to Daniel, Amanda, and Samantha.

Lucille's story was arguably the best way for Daniel to uncover the necklace's mysteries...

Lucille notes that she did not think Miyagi had told Daniel this story, unaware of the latter's research into the newspaper clipping and Miyagi's other secrets. Thankfully, though, the answers to these secrets were within Daniel's family the entire time. The strong connection between Miyagi and Lucille meant that the latter was trusted with the story, with Miyagi likely not telling Daniel due to his hot-headedness. After all, Cobra Kai season 6, part 3 outlines how out of balance Daniel becomes when learning of Mr. Miyagi's past, meaning Lucille's story was arguably the best way for Daniel to uncover the necklace's mysteries.

Mr. Miyagi’s Necklace Has Now Been Given To Samantha LaRusso

The Necklace Has Found Its Next Owner

The final development regarding Miyagi's necklace in Cobra Kai season 6, part 3 concerned its next owner. At the aforementioned family dinner scene in Cobra Kai season 6's finale, Lucille first mentions that she has the necklace as she physically brought it with her. Lucille unveils the necklace, revealing that she is giving it to Samantha on Miyagi's orders. After reclaiming the necklace and later befriending the LaRusso family, Miyagi gave it to Lucille and told her to present the heirloom to Sam when the moment was right.

In Cobra Kai season 6, part 3, Sam's life changes when she realizes she has nothing left to fight for in karate. This also leads her to the decision to pursue a life away from the valley, specifically in Okinawa. Sam is accepted into an exchange year to spend time studying in Miyagi's homeland, which strikes Lucille as the perfect time to present her with the necklace. Not only does this make sense on Lucille's part in fulfilling Miyagi's wish for Sam to have it, but it also renders the journey full circle.

The necklace was first given to Miyagi in Okinawa when he moved to the United States. Its journey then saw it pass from owner to owner, rightful or wrongful, before making its way to Lucille. Now, the necklace will find its way back to Okinawa in the hands of Sam. This, as well as the other answers provided in Cobra Kaiseason 6, part 3, make the story of Miyagi all the more satisfying than it already was, ending the mysterious tale off on a heartwarming final note.
