Collin Morikawa parents are Debbie Morikawa and Blaine Morikawa. Debbie and Blaine own a laundry named Yee Yuen in downtown LA.

Similarly, his mom and dad are the ones who introduced him to gold when he was just five years old. They convinced the organizers of a junior golf camp at Scholl Canyon to let their son participate in the sport. 

Morikawa was officially too young to play golf at five. However, people noted that his golf swing machines were superior to other youngsters his age. As a result, golf coaches became interested in him and began to train him, and significantly, his game began to improve. 

Besides, he is presently the top-ranked golfer in the World Amateur Golf Ranking and the first American to win the European Tour's Race to Dubai. 

Who Are Blaine and Debbie Morikawa?

Collin Morikawa mom Debbie and dad Blaine Morikawa run a laundry business name Yee Yuen Laundry and Cleaners.

The firm is located in downtown Los Angeles. 

Morikawa comes from a mixed ethical family, who grew up in the shadow of a Japanese American father from Hawaii and a Chinese American mother from South Carolina, as per a Twitter post. 

With a family born in Maui, Morikawa got the opportunity to play the Bill Coore/Ben Crenshaw design during one of his vacation visits. 

He doesn't recall much about the course that day, but he knew it was a momentous event. At the time, he was nine years old, sitting outside the clubhouse, taking a family photo. 

Mother Debbie Morikawa

Debbie Morikawa started a laundry business with her husband Blaine.

She is the company's president and looks after the business delivering linens, tablecloths, and household items to local restaurants and homes. On the other hand, their family's income from the corporation helps with their home bills and their children's decent upbringing.

Furthermore, his mother is a University of Southern California alumni, which might explain why her oldest son is a Trojan supporter since he graduated from the same university. 

Father Blaine Morikawa

Collin father Blaine Morikawa is a native of Maui, Hawaii. Blaine is of Japanese ancestry and lives in California with his wife and kids.

Additionally, Morikawa's grandpa (Blaine father) is also from neighboring Lahaina, where one of his extended family members managed a restaurant, according to Golf Digest
