Who Is Kyoko Chan Cox?
Kyoko Chan Cox is the daughter of Yoko Ono and Anthony Cox. She was born on August 8, 1963, in Tokyo, Japan. Her life started in an artistic family filled with music, movies, and creativity.
Kyoko has Japanese-American roots. She now lives in the United States, far from the spotlight. Even though she comes from a very famous family, she lives a private and quiet life today.
She is also known as Kyoko Ono Cox, and for some time, she had a different name too — but we’ll get to that later. Her story is not loud or flashy, but it is special and worth knowing.
Kyoko Chan Cox’s Early Life
Kyoko’s early years were filled with art, film, and music. Her mother, Yoko Ono, was a well-known artist and peace activist. Her father, Anthony Cox, was a film producer and art promoter. So Kyoko was surrounded by creativity from the very beginning.
She also went to Walter Reed Junior High School in North Hollywood. She lived part of her childhood in the U.S., learning both Japanese and English. Everything seemed normal in her young life, but that was about to change.
Kyoko Chan Cox’s Parents
Kyoko’s parents had very different personalities. Yoko Ono was known all around the world for her art, music, and peace work. She later married John Lennon from The Beatles. Her father, Anthony Cox, also worked in creative spaces, but he lived a quieter life.
Yoko and Anthony met in the early 1960s. They got married in 1962, before Yoko became truly famous. They worked on projects together and shared a love for art. But soon, their relationship started to fall apart.
Kyoko’s Parents Got Divorced
Yoko Ono and Anthony Cox divorced in February 1969. Their marriage didn’t last, and that’s when a custody battle started. Both parents wanted to raise Kyoko, but they couldn’t agree.
In 1971, a court gave full custody to Anthony Cox. Yoko was heartbroken. After that, Anthony took Kyoko and moved to Denmark. Yoko didn’t know what would happen next — and sadly, things only got worse.
Kyoko Without Her Mother
After moving to Denmark, Anthony Cox made a big decision. He cut off all contact with Yoko and the outside world. He changed Kyoko’s name to Ruth Holman and joined a strict religious group called The Walk.
Kyoko spent her childhood in hiding, away from her mother, media, and everyone else. For more than 20 years, Yoko Ono had no idea where her daughter was. She searched, wrote letters, and even traveled with John Lennon to find her. But it didn’t work.
In 1980, when John Lennon died, Yoko received a short telegram from Anthony and Kyoko. It gave her hope, but she still didn’t know where Kyoko was. It took many more years before things changed.
Kyoko Chan Cox’s Career
Kyoko started acting when she was still young. Her first film was called No. 4, made in 1966. After that, she appeared in a few more art films. These were not big movies, but more like quiet, creative films.
Some of her best-known work includes Bed Peace (1969), 3 Days in the Life (1970), and Vain Glory (1986). She also appeared in The Real Yoko Ono (2001), which was about her mother’s life.
Most of these films were made with help from her father, Anthony Cox. He liked to make artistic, short films that shared simple but deep messages. Kyoko was often part of these projects.
Later in life, Kyoko stepped away from the camera. Some sources say she may have worked as a teacher, but that is not fully confirmed. Still, it seems she has always stayed close to creative and learning spaces.
Kyoko Chan Cox Is Married to Jim Helfrich
As Kyoko grew up and started her own life, she got married to a man named James “Jim” Helfrich. He was a lawyer by profession. They lived a quiet life together, away from the media.
They had two children. The first is a daughter named Emi, and the second is a son named Jack. Both children are talented and creative, just like their family.
Later, Kyoko and Jim decided to part ways. They got divorced in January 2018. Even after the divorce, Kyoko stayed strong and focused on raising her children and living a calm life.
Kyoko’s Life Today
Today, Kyoko Chan Cox lives a very quiet and peaceful life. She stays away from the spotlight. She does not do public interviews, and she is not on social media.
She lives in Denver, Colorado, in the United States. Most people don’t know much about her day-to-day life, and that’s just how she likes it. She enjoys her privacy.
Even though she comes from a famous family, she chooses not to live like a celebrity. She keeps things simple. Her focus seems to be on family, peace, and quiet living.
Kyoko Chan Cox’s Net Worth
Kyoko has never spoken publicly about her money. But sources say her net worth is somewhere between $1 million and $5 million. Most of this likely came from her early acting work and private projects.
Her mother, Yoko Ono, is reported to have a very high net worth — around $700 million. Her father, Anthony Cox, is said to have around $5 million.
But Kyoko never lived a flashy life. She never showed off or chased fame. She lives simply and stays out of the spotlight. That’s what makes her story so calm and different.
