What Is Kiyomi Cook's Ethnicity?

Kiyomi Cook is of mixed Japanese and Caucasian heritage. Her mother, Carol Cook (née Tsuhako), is of Japanese descent and grew up in Hawaii — where the Japanese-American community is among the largest and most historically established in the United States. Her father, Karl Cook, is of white American/Caucasian ancestry.

The name "Kiyomi" (清美 in Japanese) is a traditionally Japanese feminine name meaning "pure beauty" — a meaningful choice by her mother that reflects the family's Japanese heritage. Notably, Kiyomi is the only one of her siblings — she has a sister named Kerri and a brother named Kevin — whose given name is distinctly Japanese, which suggests a deliberate decision to honor the family's Japanese heritage through naming.

So to answer the most-searched questions directly: Kiyomi Cook's ethnicity is Japanese-American on her mother's side and Caucasian white American on her father's side. She is biracial, with a Japanese-Hawaiian mother and a white American father.

Mother's Side: Japanese-Hawaiian Heritage

Kiyomi Cook's mother, Carol Cook (née Tsuhako), grew up in Hawaii and is of Japanese-American descent. The Tsuhako surname is Japanese in origin — a compound surname with roots in Japanese naming conventions, carrying the kind of specificity that suggests a well-established Japanese-American family with roots in Japan's immigration wave to Hawaii.

Japanese immigration to Hawaii began in earnest in 1868 and accelerated through the Meiji era as workers arrived to labor on the islands' sugar and pineapple plantations. By the mid-20th century, Japanese-Americans had become the largest ethnic group in Hawaii, and Japanese culture became deeply interwoven with Hawaiian life. Carol Tsuhako's family is part of this rich Japanese-Hawaiian diaspora story.

The connection to Hawaii also explains Kiyomi and Marcus Mariota's bond — both came from families with deep Hawaiian roots, even though Kiyomi herself was born in Gresham, Oregon. Shared Hawaiian heritage and values around community, family, and aloha spirit formed a natural bridge between them.

Father's Side: Caucasian Heritage

Kiyomi Cook's father, Karl Cook, is of white American/Caucasian ancestry. His specific European heritage (English, German, Irish, or other Western European lineages that are common among white Americans from Oregon) has not been publicly documented. He raised Kiyomi in Gresham, Oregon, a suburb of Portland with a diverse and growing Japanese-American community.

The Cook family gave Kiyomi two worlds — her father's mainstream American Oregonian upbringing and her mother's Japanese-Hawaiian cultural traditions — which shaped her as someone comfortable bridging multiple cultural identities.

Marcus Mariota's Own Ethnicity

Since searches for "Marcus Mariota wife ethnicity" are often accompanied by questions about Marcus himself, it is worth establishing his background clearly.

Marcus Mariota is of Samoan and German descent. His father, Toa Mariota, is Samoan — he grew up in American Samoa before attending Chaminade University in Hawaii, where he met Alana Deppe-Mariota, Marcus's mother. Alana grew up in Alaska and is of German descent. This makes Marcus Mariota half-Samoan and half-German-American, born and raised in Honolulu, Hawaii.

Marcus is a proud representative of Pacific Islander heritage in American sports, having been named the Polynesian Pro Football Player of the Year in 2016.
