Pat Morita Had To Come Up With His Own Accent

Pat Morita was born in California and he didn’t have the accent that he used on the show. He decided to use an exaggerated Chinese Pidgin English dialect. He was told his accent didn’t work since he was Japanese-American. He decided that his character had a Japanese father and Chinese mother. That accent also worked well for him as Mr. Miyagi in the original Karate Kid movies.
