Shohei Ohtani has become one of baseball’s biggest international stars, but the Los Angeles Dodgers player has always preferred to keep his family life away from public attention. While millions of fans follow his performances on the field, his relationship with his wife, Mamiko Tanaka, has attracted growing interest since their surprise marriage announcement.
Shohei Ohtani’s wife is Mamiko Tanaka, a former professional basketball player from Japan. The couple confirmed their marriage in February 2024, and they welcomed their first child, a daughter, in April 2025. Although Tanaka occasionally accompanies Ohtani to baseball games and public events, she has largely maintained a private lifestyle. Her own athletic background has also made their relationship particularly interesting, as both have experienced the demands of competing professionally.
Who Is Shohei Ohtani’s Wife Mamiko Tanaka?
Mamiko Tanaka is a former Japanese professional basketball player who became internationally recognised after her marriage to Shohei Ohtani.
She was born on December 11, 1996, in Japan and is 29 years old as of October 2026.
Before becoming widely known as Ohtani’s wife, Tanaka had already established herself as a talented basketball player.
She competed at the university level before joining the Fujitsu Red Wave, a professional women’s basketball team in Japan.
Standing approximately 5 feet 11 inches tall, Tanaka played as a forward and was known for her athletic ability and contributions to her team.
Her sporting career gave her experience with demanding training schedules, competitive pressure and professional team environments.
Unlike many partners of internationally famous athletes, Tanaka understands the challenges of professional sport from personal experience.
Although she retired from basketball in 2023, her athletic achievements remain an important part of her background.
Since marrying Ohtani, she has occasionally appeared at Dodgers games and public celebrations while continuing to protect her privacy.
Mamiko Tanaka’s Age and Early Life
Mamiko Tanaka was born on December 11, 1996, making her 29 years old in 2026.
She grew up in Japan, where she developed an interest in basketball during her younger years.
Her commitment to the sport eventually led her to Waseda University, one of Japan’s well-known educational institutions.
During her university years, she continued developing her basketball skills and gained valuable competitive experience.
Playing at the collegiate level helped prepare her for the demands of professional basketball.
Her performances eventually created opportunities to join a major Japanese women’s basketball team.
Although Tanaka is now recognised internationally because of her marriage, her early life was focused on education, athletic development and building a career in basketball.
She has generally avoided sharing extensive details about her childhood and family background.
This preference for privacy is something she shares with Ohtani, who also rarely discusses personal matters publicly.
Mamiko Tanaka’s Professional Basketball Career
Before becoming Shohei Ohtani’s wife, Mamiko Tanaka spent several years competing in Japanese professional basketball.
She joined the Fujitsu Red Wave in 2019 after playing for Waseda University.
The team competes in Japan’s Women’s Basketball League, one of the country’s leading competitions for female basketball players.
Tanaka played as a forward, a position requiring versatility, physical strength and the ability to contribute offensively and defensively.
During her professional career, she competed against some of Japan’s strongest basketball players.
In her final season, Tanaka appeared in 28 games.
She recorded a field-goal shooting percentage of approximately 47.7 percent and a free-throw percentage of 69.9 percent.
These figures reflected her ability to contribute as part of the team’s offensive rotation.
Tanaka retired from professional basketball in 2023.
Although she has not publicly discussed every detail behind her decision to retire, her career remains an important achievement independent of her husband’s baseball success.
When Did Shohei Ohtani and Mamiko Tanaka Get Married?
Shohei Ohtani publicly announced his marriage in February 2024.
The announcement surprised baseball fans because he had not previously confirmed a serious romantic relationship.
At the time, Ohtani was preparing for his first season with the Los Angeles Dodgers after signing a historic contract with the team.
He shared the marriage news through a social media statement written in English and Japanese.
The baseball star explained that he was beginning a new chapter both professionally and personally.
However, he did not initially reveal his wife’s name.
Instead, he described her as someone special from his home country of Japan.
Ohtani also requested that journalists respect his family’s privacy.
His decision to keep the announcement simple reflected his long-standing preference for separating his personal life from his baseball career.
The exact wedding date and location have not been publicly disclosed.
Although the marriage was announced in February 2024, the couple have not shared extensive details about their ceremony.
How Did Shohei Ohtani Reveal Mamiko Tanaka as His Wife?
Following Ohtani’s surprise marriage announcement, fans became curious about the identity of his wife.
Approximately two weeks later, the Los Angeles Dodgers shared photographs of players and their families travelling to South Korea.
Among the pictures was Ohtani standing beside Mamiko Tanaka.
The team identified her as his wife, effectively confirming the identity of the woman he had married.
The photographs were taken as the Dodgers prepared to travel to Seoul for their season-opening series against the San Diego Padres.
The couple’s appearance quickly attracted attention in Japan, South Korea and the United States.
When they arrived at Incheon International Airport in March 2024, they were greeted by photographers and baseball supporters.
Ohtani wore a dark athletic outfit, while Tanaka appeared in a coordinated black ensemble.
Although the attention was considerable, the couple remained composed during their arrival.
Their appearance marked one of the first occasions when fans saw them together publicly as husband and wife.
How Did Shohei Ohtani and Mamiko Tanaka Meet?
Shohei Ohtani and Mamiko Tanaka have not publicly shared a detailed account of their first meeting.
Their relationship developed privately before Ohtani announced his marriage in 2024.
Because both are Japanese athletes, fans have naturally been curious about whether their sporting backgrounds played a role in bringing them together.
However, the exact circumstances of their introduction have not been fully confirmed.
Ohtani has occasionally discussed his wife in interviews, but he has avoided revealing unnecessary personal details.
His approach appears intended to protect their relationship from excessive media attention.
Tanaka has also maintained a relatively low public profile since her basketball retirement.
Rather than discussing their romance extensively, the couple have allowed occasional public appearances to provide glimpses into their life together.
Their shared experience as professional athletes is one of the clearest connections between their backgrounds.
Shohei Ohtani and Mamiko Tanaka Welcome Their First Child
Shohei Ohtani and Mamiko Tanaka became parents in April 2025.
On April 19, 2025, Ohtani announced that his wife had given birth to their first child, a daughter.
The Dodgers star shared the news through a social media post featuring a photograph of their newborn baby’s feet.
He expressed gratitude to his wife and excitement about becoming a father.
The announcement received widespread attention from baseball fans around the world.
However, the couple did not reveal their daughter’s name or detailed birth information.
Their decision was consistent with Ohtani’s preference for keeping his family life private.
The birth marked an important personal milestone for the couple, coming a little more than a year after their marriage announcement.
Ohtani has continued balancing the responsibilities of fatherhood with his demanding Major League Baseball career.
Mamiko Tanaka’s Public Appearances With Shohei Ohtani
Although Mamiko Tanaka generally avoids the spotlight, she has accompanied her husband to several important events.
One of their most memorable appearances came in May 2024 at the Los Angeles Dodgers Foundation Blue Diamond Gala.
The event marked the couple’s red carpet debut.
They posed for photographs together and were also pictured with British singer Ed Sheeran.
Tanaka’s appearance attracted considerable interest because fans had previously seen relatively few public photographs of her with Ohtani.
She has also attended Dodgers games and celebrated important team achievements.
In September 2024, Tanaka was seen on the field after the Dodgers secured the National League West division title.
She joined Ohtani and their dog, Decoy, during the celebrations.
The moment offered fans a rare glimpse of the couple enjoying a major baseball achievement together.
Despite these appearances, Tanaka has not pursued the kind of highly public celebrity lifestyle often associated with professional athletes’ partners.
Shohei Ohtani and Mamiko Tanaka’s Dog Decoy
One of the most recognisable members of Shohei Ohtani’s family is his dog, Decoy.
The Dutch Kooikerhondje has become popular among Dodgers supporters and frequently attracts attention during public appearances.
Ohtani introduced Decoy to fans before announcing his marriage.
The dog later became part of the couple’s family story.
When Ohtani shared his marriage announcement, he referred to beginning a new life with his wife and their dog.
Decoy has appeared in family photographs and participated in baseball-related events.
The dog also became famous for delivering a ceremonial first pitch at Dodger Stadium.
His appearances have delighted fans and provided a lighter side to Ohtani’s otherwise private personal life.
For Ohtani and Tanaka, Decoy remains a familiar companion as they balance family responsibilities with the demands of professional baseball.

Her decision to maintain privacy is understandable given the enormous attention surrounding her husband’s career.
