Pat Morita Biography: Ethnicity, Martial Arts, and Friendship

Few movie characters have left as lasting an impression as Mr. Miyagi, the wise and gentle karate master from The Karate Kid.

The difference between acting and real skill

• Morita’s background was in stand-up comedy, not martial arts. He started in nightclubs in the 1960s (IMDb (film database))

How he prepared for The Karate Kid role

• Morita studied the choreography under the film’s martial arts coordinator and practiced daily to achieve the on-screen believability.

The catch: Morita’s lack of formal training doesn’t diminish his achievement; it elevates the craft he brought to a role that required him to appear as a master.

What movies did Pat Morita star in?

What was Pat Morita’s famous role?

He is best known for playing Mr. Miyagi in The Karate Kid (1984) and its sequels, a role that earned him an Academy Award nomination.

The Karate Kid film series

• Morita played Mr. Miyagi in The Karate Kid (1984), The Karate Kid Part II (1986), The Karate Kid Part III (1989), and The Next Karate Kid (1994) (IMDb (film database))

Other notable films and TV roles

• Morita played Arnold on the sitcom Happy Days from 1975 to 1983 (TCM (film archive))
• He also appeared in films such as Midway (1976), Bloodsport (1988) (uncredited), and Spy Kids 3-D: Game Over (2003).

His comedic work on Happy Days

• Morita’s background in stand-up comedy made him a natural fit for the sitcom format, and his character Arnold became a fan favorite.

Why this matters: For actors of color in the 1980s, a single defining role often became a trap. Morita’s ability to turn that role into a cultural icon is a rare achievement, but it also meant audiences never got to see the full range of his abilities.

Pat Morita’s life was a study in contradictions: a comedian who played a stoic martial arts master, a Japanese American who faced internment yet became a beloved icon, an actor with no real fighting skill who made millions believe in the “wax on, wax off” philosophy. For the generation that grew up with The Karate Kid, honoring Pat Morita means remembering the man behind the myth and recognizing his real story of resilience, talent, and the quiet power of representation.
