Who Is Kathleen Yamachi? The Amazing Life Story of Pat Morita’s First Wife

Kathleen Yamachi is best known as the first wife of actor and comedian Pat Morita, the performer who later gained worldwide fame as Mr. Miyagi in The Karate Kid. Major references confirm that the two married in 1953 and divorced in 1967, years before Morita reached his biggest successes. Kathleen never built a public career, so reliable details about her own life are limited. This article separates what credible sources confirm from what remains unverified, and it places her in the context of Morita’s early years, his family, and his later marriages.

Who Is Kathleen Yamachi?

Kathleen Yamachi is the first wife of Noriyuki “Pat” Morita, an American actor and comedian. Wikipedia’s entry on Morita lists her first among his three spouses, with the marriage beginning in 1953 and ending in 1967. Outside that marriage, she held no public profile. As far as published records show, she did not act, perform, or give interviews about her time with Morita.

That thin record shapes every search about her. Morita’s fame gives her name interest, yet the paper trail around Kathleen herself is small. Several entertainment websites publish confident details about her birth year, family background, and jobs, but those pages rarely name a primary source. This article sticks to facts that appear in established references and labels everything else as unconfirmed.

Who Was Pat Morita, the Man Kathleen Yamachi Married?

Noriyuki “Pat” Morita came into the world on June 28, 1932, in Isleton, California, to Japanese immigrant parents. His father, Tamaru, arrived from Kumamoto Prefecture in 1915, and his mother, Momoe, arrived in 1913. Morita also had an older brother named Hideo, who went by Harry.

At age two, Morita developed spinal tuberculosis, also known as Pott disease. He spent most of the next nine years in hospitals, including the Weimar Institute in Weimar, California, and Shriners Hospital in San Francisco. He spent long periods in a full body cast and heard that he might never walk. After extensive spinal surgery, he learned to walk again.

The hospital released him at age 11, and he traveled straight to the Gila River camp in Arizona to join his family, who were interned during World War II. About a year and a half later, he moved to the Tule Lake War Relocation Center.

After the war, the family returned to the Bay Area. Morita graduated from Armijo High School in Fairfield in 1949, and the family later ran Ariake Chop Suey, a restaurant in Sacramento. Morita told jokes to customers and served as master of ceremonies for group dinners. Those restaurant nights gave him his first audience. This was the world Morita lived in when he married Kathleen.

When and How Did Kathleen Yamachi Marry Pat Morita?

Kathleen Yamachi married Pat Morita in 1953. Wikipedia and other biographical references confirm the year, and several entertainment websites give the date as June 13, 1953. Morita was in his early twenties at the time, and his family still ran the Sacramento restaurant.

Some articles claim the couple met in Sacramento in the early 1950s and that Kathleen was several years older than Morita. Some also say they started married life above the family restaurant. The sources reviewed for this article do not back those claims with interviews, court records, or a major biography. They may be accurate, but readers should treat them as unconfirmed.

The lack of confirmation does not reduce the importance of the marriage. It lasted about 14 years, which covers most of Morita’s twenties and thirties. During that stretch, he lost his father, changed careers twice, and took his first serious steps toward entertainment.

What Was Married Life Like for Kathleen Yamachi and Pat Morita?

The marriage covered the years when Morita moved from restaurant work to office jobs and then to the comedy stage. Kathleen left no public account of those years, so the best view comes from Morita’s own career history.

In 1956, a driver who fled the scene killed Morita’s father while he walked home from an all night movie. Morita and his mother kept the family restaurant open for another three or four years. Morita then needed a steady paycheck. Wikipedia says he took the job to support a wife and a newborn child. He became a data processor in the early 1960s for the Department of Motor Vehicles and other state agencies, then worked a graveyard shift at Aerojet General. He later rose to department head at Lockheed, where he handled communication between engineers and programmers on missile projects.

That timeline raises one puzzle. The account of a newborn in the early 1960s does not match the 1954 birth year reported for Erin. Sources disagree, so the exact timing of the family’s early years stays uncertain.

Morita eventually burned out on the corporate track. He quit and tried show business, working as a comedian in small clubs in Sacramento and San Francisco. He adopted the stage name Pat Morita, partly because other comedians named Pat worked the circuit and partly in memory of a priest he had befriended as a boy. A ventriloquist named Hank Garcia urged him to try Los Angeles. There, Sally Marr, the mother of comedian Lenny Bruce, acted as his agent and manager. Morita opened for performers such as Vic Damone and Connie Stevens, and he learned from his mentor, comedian Redd Foxx. He also used the nickname “The Hip Nip” on stage.

Kathleen’s exact role in this change is not documented. Still, the move from a secure state job to unpredictable comedy work took place during their marriage, and it affected any household that depended on his income.

Did Kathleen Yamachi and Pat Morita Have Children?

Kathleen Yamachi and Pat Morita reportedly had one daughter, Erin Morita. Entertainment sources describe Erin as Morita’s eldest child and place her birth in 1954. Entertainment listings name Erin, Tia, and Aly Morita among his daughters, and Wikipedia states that Morita had three children in total.

Morita’s third wife, Evelyn Guerrero, had no children with him. She became a stepmother to his daughters when they married in 1994.

Beyond Erin’s name and approximate birth year, the public record says little about her. As a private individual, she has not built a public profile, and this article does not try to fill in personal details that she has not shared.

Why Did Kathleen Yamachi and Pat Morita Divorce?

No credible source has published a confirmed reason for the divorce. Neither Kathleen nor Pat Morita has offered a public explanation that surfaced in the references reviewed here. The marriage ended in 1967 after roughly 14 years.

The timing offers context but not an answer. In 1967, Morita was several years into his shift from steady office work toward entertainment. That same year, he appeared in Thoroughly Modern Millie, one of his earliest film roles. Many websites suggest that career stress, money worries, or life in the entertainment business pulled the couple apart. Those explanations sound plausible, but nobody has verified them, and they read as speculation.

A responsible summary sticks to the facts. The couple married in 1953, and they divorced in 1967. Anything more specific requires a source that names its evidence.

What Happened to Pat Morita After the Divorce?

After the divorce, Pat Morita built one of the most recognizable television and film careers of his era. He married Yukiye Kitahara in 1970, and that marriage ended in 1989. He then married actress Evelyn Guerrero in 1994.

His career took off in the 1970s. He played Ah Chew on Sanford and Son and Captain Sam Pak on MASH*. He then played diner owner Matsuo “Arnold” Takahashi on Happy Days, a role that ran from 1975 to 1983. In 1976, he starred in Mr. T and Tina, which Wikipedia describes as the first Asian American sitcom on network television. ABC canceled it after five episodes.

His defining role arrived in 1984. Producers hesitated to cast Morita as Mr. Miyagi in The Karate Kid because audiences knew him as a comedian, and he reportedly auditioned five times before he won the part. The performance earned him an Academy Award nomination for Best Supporting Actor and a Golden Globe nomination. He returned as Mr. Miyagi in two sequels and later starred in The Next Karate Kid in 1994.

Other highlights followed. He starred in the detective series Ohara, earned Emmy and Golden Globe recognition for the television film Amos, and voiced the Emperor of China in Disney’s Mulan. He received a star on the Hollywood Walk of Fame in 1994. Pat Morita died of kidney failure on November 24, 2005, at his home in Las Vegas at age 73.

Kathleen Yamachi was no longer his wife when The Karate Kid made him a star. She shared the harder, quieter years that came before that success.

What Do We Know About Kathleen Yamachi’s Life Today?

Nothing verified is available about Kathleen Yamachi’s life after 1967. No confirmed public records describe whether she remarried, what work she did, or where she lived. Some websites claim she returned to Northern California and lived modestly, but those pages do not cite sources, so readers should treat the claims with caution.

This gap has a simple explanation. Kathleen chose no public life, and privacy is her right. Because she is a private individual, this article does not speculate about where she lives or whether she is still alive. Readers who want to learn more about her should look for statements from her family or from established biographers rather than trusting unsourced entertainment sites.

Why Do People Still Search for Kathleen Yamachi?

People search for Kathleen Yamachi because Pat Morita’s legacy keeps attracting new audiences. The Netflix series Cobra Kai renewed interest in the original film and its cast, and the show dedicated an episode to Morita’s memory. The 2025 film Karate Kid: Legends used archival footage of his Mr. Miyagi performance. Documentaries such as More Than Miyagi: The Pat Morita Story explore his complicated life, including his childhood illness, his years in an internment camp, and his struggles as an adult.

Each new look at Morita raises questions about the people around him. Kathleen represents the earliest chapter of his adult life, the years before fame. That makes her a natural starting point for readers who want to understand how a boy who once could not walk became an Oscar nominee.

Conclusion

Kathleen Yamachi matters to Pat Morita’s story because she shared his life from 1953 to 1967, long before he became Mr. Miyagi. The verified facts are few: the marriage, the divorce, and a daughter named Erin. Kathleen kept her life private, and honest coverage respects that choice. Readers who want more should rely on sourced biographies and reject unverified claims.
