1. Yuki Imoto is Rampage Jackson's Ex-Wife, Not His Current Partner

Despite the ongoing public interest, Yuki Imoto, often referred to as Yuki Jackson, is no longer married to the MMA star. The couple's relationship began in the early 2000s, and they officially married in 2002.

Yuki, who is Japanese, became a central figure in Rampage's life and was known by many of his friends and gym buddies as 'Mama-san,' a term of respect and affection.

However, after nearly two decades together, Quinton Jackson filed for divorce from Yuki Imoto in 2020, citing irreconcilable differences. The filing marked the official end of their long-term marriage, though their family connection remains through their children.

2. The Paternity Test Scandal and Temporary Separation

Yuki and Rampage’s marriage was turbulent, facing a major crisis early on due to Rampage's infidelity. In 2006, the couple separated after a paternity test confirmed that Rampage had fathered a son, Raja Jackson, with another woman in 2000.

Despite the infidelity, the couple eventually reconciled and continued to raise their family together for many years. Yuki is credited with helping to raise Raja, along with their two biological children, Elijah and Naname Nakia Jackson.

This period highlights Yuki's resilience and commitment to the family unit, even in the face of public and personal setbacks.

3. Yuki and Rampage's Biological Children: Elijah and Naname Nakia

Yuki Imoto and Quinton Jackson share two biological children: a son, Elijah Jackson, and a daughter, Naname Nakia Jackson.

Naname Nakia, born on July 15, 2005, is the youngest of Rampage’s children and his only daughter. She represents the Japanese-American blend that defines a significant part of the Jackson family's heritage.

Both children grew up largely away from the intense media scrutiny that followed their father's career, thanks in part to Yuki's efforts to maintain a private family life.

4. The Shocking Revelation About Raja Jackson's Biological Mother

The most recent and shocking news that has brought the Jackson family back into the headlines is related to Raja Jackson, the son Yuki helped raise. Raja was involved in a highly controversial and violent incident in late 2024/early 2025, which led to his arrest and public debate, with some onlookers even calling the assault "attempted murder."

In a candid livestream addressing the controversy, Rampage Jackson made a devastating revelation to explain his son's behavior. He stated that Raja "has not been the same since his mom got murdered."

This statement clarifies that the victim of the alleged murder was Raja's biological mother, *not* Yuki Imoto (Rampage's ex-wife). However, this tragedy is a core part of the family's history, and it profoundly impacted the child Yuki raised as her own. The revelation provides a tragic context for the recent family drama, showcasing the deep, hidden pain that has been carried by the Jackson family for years.

5. Yuki Jackson's Life Post-Divorce: A Return to Privacy

Since the 2020 divorce filing, Yuki Imoto has largely retreated from the public eye. Unlike many celebrity ex-spouses, she has maintained a low profile, focusing on her life and family away from the cameras and the world of mixed martial arts.

Her current profession and exact whereabouts are not widely publicized, suggesting a deliberate return to privacy following years of being a supportive but often overlooked figure in the life of a global sports and entertainment icon. Her legacy remains as the woman who was a constant presence during Rampage Jackson's most successful years and the mother figure to all of his children, earning her the lasting, respectful title of 'Mama-san' among those who know the family best.
