Kana Grace Nootenboom is one of those fascinating figures whose story sits just outside the brightest circle of celebrity. Her family name carries the unmistakable sound of American entertainment, Japanese entrepreneurship, fashion, and music, yet Kana has largely chosen a different stage. Rather than building a public career around the Aoki name, she developed a professional life in psychology and marriage and family therapy.
Known in some records as Kana Aoki Nootenboom, Grace Aoki, or simply Kana Nootenboom, she is the eldest daughter of legendary Benihana founder Hiroaki “Rocky” Aoki and his first wife, Chizuru Kobayashi. Today, she is associated primarily with clinical therapy work in Henderson, Nevada, where she has served as a licensed marriage and family therapist and clinical director.
Her story is therefore less about celebrity and more about perspective. She grew up inside a complicated family tree, watched her father’s business empire expand, experienced the realities of a blended family, and eventually built a career centered on helping other people navigate relationships, trauma, grief, communication, and personal growth.

Growing Up as a Daughter of Rocky Aoki
To understand Kana, I think it helps to picture the world into which she was born. Her father, Hiroaki “Rocky” Aoki, was not the kind of entrepreneur who quietly opened a neighborhood restaurant and went home at five.
Rocky was theatrical, ambitious, athletic, and relentlessly energetic. After establishing Benihana in the 1960s, he transformed restaurant dining into entertainment. Chefs cooked directly in front of guests, knives flashed through the air, flames rose from the teppanyaki grill, and dinner became something closer to a performance.
Kana was one of the children raised within that expanding empire.
Her mother, Chizuru Kobayashi, was Rocky’s first wife. The couple married in 1964 and divorced in 1981. Kana’s childhood therefore unfolded during the years when Rocky’s business was becoming increasingly successful while his personal life was also becoming increasingly complicated.
The Aoki family eventually included seven children connected to Rocky through several relationships. Kana’s family tree consequently became less like a straight line and more like a branching map.
Her full siblings with Chizuru included Kevin Aoki and Steve Aoki. Her half-siblings included Kyle N. Aoki, Echo V. Aoki, Devon Aoki, and Jenifer Crumb.
That family structure would later become significant not only personally but legally.

| Brent H. Nootenboom | Husband | Creative and technology related professional background |
| Yumi Nu | Daughter | Model, singer-songwriter, entrepreneur |

Choosing Psychology Instead of the Family Business
Kana’s profession choice has a softly remarkable quality.
With a father who established a global restaurant company and siblings who pursued careers in music, fashion, entertainment, and business, she might have easily stayed within the family circle. Instead, she was drawn to psychology.
Her educational background reportedly included a bachelor’s degree from New York University, as well as graduate studies in clinical psychology and marriage and family therapy at Vanguard.
This method eventually led to professional licensing in California and Nevada.
Kana’s art demonstrates a concern in the architecture of human relationships. She has worked with individuals, couples, children, adolescents, families, and older folks to address a variety of issues such as anxiety, depression, trauma, grief, behavioral problems, ADHD, anger management, attachment issues, communication challenges, and relational trust.
Her therapeutic toolset is as extensive.
She has used methodologies such as cognitive behavioral therapy, EMDR, Internal Family Systems, mindfulness, play therapy, sandtray therapy, Gottman Method techniques, neurofeedback and brain mapping, and ketamine-assisted psychotherapy. She has also used spiritually informed and Christian therapy viewpoints when working with clients from various backgrounds.
Rather of viewing emotional troubles as discrete issues, her professional attitude stresses the big picture. Family patterns, memories, connections, beliefs, and personal qualities can all fit together to form one puzzle.
Healing With Grace in Henderson
Kana has served as Clinical Director at Healing with Grace Counseling and Ketamine Center in Henderson, Nevada.
The practice has offered individual and relationship counseling along with services for families, children, adolescents, and seniors. Her professional profile places considerable emphasis on trauma-informed care and approaches designed to help clients understand the deeper patterns behind emotional distress.
Her use of EMDR is particularly relevant to trauma-focused treatment, while Internal Family Systems explores different emotional “parts” within a person’s internal world.
The setting is a notable contrast to her family background.
Her father’s career was built around spectacle. Kana’s professional life is built around listening.
One career involved theatrical kitchens and crowded dining rooms. The other involves quiet conversations in which people are often discussing the things they rarely say anywhere else.
Marriage to Brent Nootenboom
Kana married Brent H. Nootenboom, who is described in various accounts as having creative and artistic interests as well as experience connected to information technology.
Together, they have maintained a notably private family life.
The couple’s daughters, however, eventually stepped into a much more visible world.
Their older daughter is Yumi Nu, born Olivia Yumi Nootenboom on September 23, 1996, in Englewood, New Jersey. Their younger daughter is Natalie Nootenboom.
The sisters inherited a complicated mixture of cultures and creative influences. Their heritage includes Japanese and Dutch roots, while their family connections place them within both the Aoki business legacy and the entertainment world.
Yumi Nu and the Next Generation
Yumi Nu has developed an identity far beyond simply being Rocky Aoki’s granddaughter.
She became known internationally as a model, singer-songwriter, and entrepreneur, while advocating for body positivity and greater representation in fashion.
In 2022, she made history as the first Asian plus-size model to appear on the cover of Sports Illustrated Swimsuit.
That achievement gave the family name another kind of visibility.
Yumi has also pursued music and became associated with her uncle Steve Aoki’s Dim Mak label. Her career combines modeling, music, entrepreneurship, and cultural representation, making her another example of the family’s unusual ability to cross creative boundaries.
Behind that public career has been Kana’s quieter influence.
Yumi and Natalie have spoken about growing up in different parts of the United States, including New Jersey, Maryland, and California. Their childhood experiences included moving between communities and confronting racism and questions about identity.
Kana’s role as their mother was not simply about managing a famous family name. She provided emotional grounding while her daughters developed their own voices.
Natalie Nootenboom and a Creative Family Tradition
Natalie Nootenboom has also entered the creative world.
She has worked in modeling, including curve and plus-size fashion, and has been associated with campaigns and fashion projects. Her interests extend into music and writing as well.
Like her sister, Natalie has spoken about self-love, family influence, and the pressures surrounding appearance and representation.
The sisters’ careers reveal an interesting generational shift.
Rocky Aoki built restaurants around performance. Steve Aoki built a career around electronic music. Devon Aoki became a fashion and film figure. Yumi and Natalie have continued that creative tradition through modeling, music, writing, and advocacy.
Kana stands somewhat apart from that pattern, but she is also part of it.
Her contribution has been less visible and more psychological: encouraging creativity while providing stability.
The Complicated Rocky Aoki Estate
The Aoki family’s history became particularly complicated after Rocky’s death in 2008.
His estate involved substantial business interests, trusts, wills, and competing claims among family members. At the center was the Benihana Protective Trust, which held interests connected to Benihana of Tokyo and related assets.
The estimated value of these interests reached tens of millions of dollars.
Kana, sometimes identified as Grace in legal proceedings, became involved in disputes surrounding the estate alongside siblings including Kevin, Kyle, and Echo. Her stepmother, Keiko Ono Aoki, was also deeply involved in the litigation.
The disputes touched on questions of testamentary capacity, undue influence, trustee responsibilities, powers of appointment, fiduciary conduct, and the interpretation of Rocky’s estate documents.
For Kana, this was a very different chapter from her professional work. The therapist who built a career around helping families communicate found herself part of a family dispute that played out in courtrooms for years.
Steve Aoki and Devon Aoki in the Estate Dispute
Steve Aoki and Devon Aoki eventually became central beneficiaries of important trust interests established through Rocky’s estate planning.
A major issue involved partial releases Rocky executed in 2002 concerning his power of appointment. Years of litigation followed over whether those releases were valid.
Appellate decisions ultimately upheld the releases, reinforcing the position of Steve and Devon regarding key trust assets.
The practical story did not end there.
Trust administration, accounting disputes, fiduciary questions, and disagreements concerning Keiko’s management continued for years. The litigation became a long legal tail attached to an estate that had already been complicated by Rocky’s multiple relationships and changing estate plans.
Steve reached the age of 45 in 2022, an important milestone under the terms governing access to certain trust interests. Devon, born in 1982, reaches that age later.

A Family Legacy With Different Definitions of Success
Kana’s tale is interesting since she did not merely inherit a famous surname. She seemed to have selected what that surname would represent in her personal life.
Her father exemplified business showmanship. Her brother, Steve, represents global music culture. Devon, her sister, symbolizes both fashion and movies. Yumi, her daughter, embodies the fashion industry’s changing landscape. Natalie maintains the creative thread.
Kana chose therapy.
That decision offers the Aoki family narrative a new texture. Not everyone in a famous family desires the limelight. Some people become the silent room behind the stage, assisting everyone else to make sense of the commotion.
Her career demonstrates that success can be evaluated through professional contribution, family relationships, and emotional connection rather than just fame.
