The Karate Kid Part II is a 1986 American martial arts drama film written by Robert Mark Kamen and directed by John G. Avildsen. It is the second installment in the Karate Kid franchise and the sequel to the 1984 film The Karate Kid, starring Ralph Macchio and Pat Morita. The Karate Kid Part II follows Daniel LaRusso (Macchio), who accompanies his karate teacher Mr. Miyagi (Morita) to see his dying father in Okinawa, only to encounter an old friend-turned-rival with a long-harbored grudge against Miyagi.

Following the success of the first installment, preparation for a sequel began immediately. Upon completion of the final script, Macchio and Morita were re-signed and additional casting took place between May and July 1985. Principal photography began in September in Los Angeles, and filming completed in December. Locations included Oahu, which was used to represent Okinawa in the film.

Shortly after his dojo’s loss in the 1984 All-Valley Karate Tournament, a furious John Kreese attacks his student, Johnny Lawrence, in the parking lot. Miyagi intervenes and passively immobilizes Kreese. He threatens a deadly blow but instead comically tweaks Kreese’s nose and walks away. Johnny and his friends leave a humiliated Kreese and Cobra Kai behind.

Six months later, Daniel visits Miyagi after a senior prom and explains that Ali has broken up with him in favor of a football player at UCLA. Miyagi receives a letter notifying him that his father is dying, prompting him to return to his home village on Okinawa Island. He tells Daniel that many years ago, he fell in love with a woman named Yukie. She was arranged to marry his best friend Sato, son of the wealthiest man in the village and fellow karate student of his father. Upon announcing his intentions to marry Yukie, Sato challenged him to a fight to the death. Instead, Miyagi left the country. Daniel decides to accompany him back to Okinawa.

Upon arrival, Miyagi and Daniel are greeted by Chozen Toguchi, who drives Miyagi and Daniel to one of Sato’s warehouses and reveals that he is Sato’s nephew. Sato appears and demands to fight Miyagi, who adamantly refuses. Arriving at the village, Miyagi and Daniel are welcomed by Yukie and her niece Kumiko. They discover that Sato has become a rich industrialist whose supertrawlers have destroyed the local fish population, impoverishing the other villagers. They are forced to rent property from Sato, who owns the village’s land title. Yukie reveals that she never married Sato because of her love for Miyagi.

Miyagi’s father dies, and Sato gives him three days to mourn before their fight out of respect. Miyagi shows Daniel the secret to his family’s karate – a den-den daiko (handheld drum) that twists back and forth, illustrating the “drum technique”, a counter-striking karate move that Daniel begins to practice. Daniel and Kumiko begin to develop a romance.

Daniel unintentionally exposes corruption in Chozen’s grocery business during an encounter in the village. Chozen accuses Daniel of insulting his honor, and they have a series of confrontations. The feud escalates when Chozen and his cronies attack Daniel and vandalize Miyagi’s family property, but Miyagi fends them off. He and Daniel plan to return home before the situation worsens, but Sato threatens to destroy the village if Miyagi refuses to fight. Miyagi finally agrees on the condition that Sato relinquishes land ownership to the villagers, describing it as a “small price” to pay for honor; Sato reluctantly agrees.
