Was the subject of a popular Internet myth - "That he owned a Japanese-style restaurant called Miyagi's on Sunset Boulevard in Hollywood, California." However, according to Morita himself in an 'about.com' interview, this was just a myth and he had nothing to do with the restaurant.

While performing as a stand-up comic, he was discovered by Redd Foxx. This led to several appearances as Ah Chew on "Sanford and Son" (1972).
The scene that sealed his nomination for Best Supporting Actor in "The Karate Kid", in which Myagi gets drunk and weeps over the death of his wife and child in the Manzanar Internment Camp was nearly cut out of the film. The studio thought the scene was un-necessary and wanted it cut. But director John G. Avildsen argued that the scene was important to Myagi's character and finally the studio relented and allowed the scene to be kept in. Also, during the casting of the film, the studio wanted legendary Japanese actor, Toshiro Mifune to play Myagi but Avildsen and producer Jerry Weintraub thought Mifune's interpretation of the character was far too serious for what the film needed.
