Mamiko Tanaka is a former Japanese professional basketball player and the wife of Los Angeles Dodgers star Shohei Ohtani.
Tanaka played for Fujitsu Red Wave in Japan’s Women’s Japan Basketball League (WJBL), competed internationally in youth basketball for Japan, and won a 2019 FIBA 3×3 Women’s Series event. Her identity became publicly known after Ohtani announced his marriage in February 2024 and the couple appeared together during the Dodgers’ Seoul Series trip the following month.
Although she is now widely recognized because of her relationship with Ohtani, Tanaka has her own substantial athletic résumé. The public record confirms her basketball career, marriage, and the couple’s announcements about their daughter. It does not confirm several frequently repeated details about their private life, including their exact wedding date or how they first met.

When did Shohei Ohtani announce his marriage?
Ohtani announced his marriage on February 29, 2024, in a statement shared on social media. He said that he had married a Japanese woman, but he did not initially identify her by name. He also said he had known his wife for approximately three or four years and that she was with him in Arizona during Dodgers spring training.
Ohtani did not disclose the exact date of the wedding. The announcement also did not provide a detailed account of the couple’s dating history or explain precisely where they first met.
How was Mamiko Tanaka identified?
Tanaka’s identity became public during the Dodgers’ trip to South Korea for the inaugural Seoul Series in March 2024. The Associated Press identified her as Mamiko Tanaka in coverage of the couple arriving in Seoul on March 15.
The couple were also seen together around the Seoul Series. On March 20, Tanaka attended Ohtani’s first game as a Dodger. An official Dodgers video description identified the woman reacting to Ohtani’s first hit and RBI as his wife, Mamiko Tanaka.

Tanaka’s basketball career
Before becoming known internationally as Ohtani’s wife, Tanaka was a professional basketball player in Japan. WJBL records list her development path through:
- Hino Daiichi Junior High School
- Tokyo Seitoku University High School
- Waseda University
- Fujitsu Red Wave
She played as a power forward and was listed at 180 centimeters and 70 kilograms in WJBL roster information. Fujitsu Red Wave is one of Japan’s established women’s basketball teams, and Tanaka’s documented playing record places her within Japan’s professional women’s basketball system rather than merely at an amateur or school level.
Was Mamiko Tanaka a WNBA player?
No reliable evidence in the available record shows that Tanaka played in the WNBA. Her documented professional career was in Japan with Fujitsu Red Wave.
She also should not automatically be described as a current member of Japan’s senior women’s national team. FIBA records show her appearances for Japan in youth competitions, but the cited record does not establish a senior-national-team career.
Her 3×3 basketball success
Tanaka also participated in 3×3 basketball. WJBL’s 2020 All-Star material lists her on the Fujitsu Red Wave roster and credits her with winning the 2019 FIBA 3×3 Women’s Series event in Xiongan, China.
That achievement is an important part of her résumé because 3×3 basketball requires a different style from the traditional five-on-five game: players must make faster decisions, defend in space, and contribute continuously on both ends of the court.
Rank #3
Tanaka’s youth international record
FIBA’s official player database records Tanaka’s participation in three youth tournaments for Japan:
| Year | Competition | Recorded average |
|---|---|---|
| 2011 | FIBA Asia Under-16 Championship | 7.7 points per game |
| 2012 | FIBA Under-17 World Championship for Women | 2.0 points per game |
| 2014 | FIBA Asia Under-18 Championship for Women | 6.6 points per game |
These statistics are tournament averages recorded by FIBA. They should not be confused with a full professional-season statistical profile.

When did Tanaka’s basketball career end?
The safest description is that Tanaka’s documented Fujitsu playing period ended around 2023. A WJBL free-agent notice dated May 1, 2023, listed her among Fujitsu Red Wave players whose status had become available for the next stage of the league process.
However, that category could include retirement, a transfer, or remaining with the same team. The notice does not independently confirm which of those outcomes applied to Tanaka. For that reason, it is more accurate to call her a former professional basketball player than to state as an established fact that she formally announced her retirement in 2023.
No complete, reliable public account of her post-basketball occupation has been established in the available sources.
When did Shohei Ohtani and Mamiko Tanaka have their first child?
Ohtani announced on December 28, 2024, that he and Tanaka were expecting their first child. The announcement included a photograph of baby shoes and a onesie, along with the couple’s dog, Decoy.

Several details are repeated online but are not established by the strongest available public record. These include:
- the exact date of Ohtani and Tanaka’s wedding;
- the precise date, location, or circumstances of their first meeting;
- a complete dating timeline;
- the identities of Tanaka’s parents;
- her exact occupation after basketball; and
- additional personal details about their daughter.
Entertainment and sports articles sometimes repeat these claims, but repetition does not make an unverified detail confirmed. The responsible distinction is between information supported by an official roster, governing-body database, league notice, MLB report, or direct public statement and information attributed only to unsourced online accounts.

Why Mamiko Tanaka is more than a celebrity spouse
Tanaka’s public profile is closely tied to one of baseball’s biggest stars, but her own athletic background is significant. She reached Japan’s professional women’s basketball ranks, represented Japan in youth international competition, played 3×3 basketball, and was part of a team that won a FIBA Women’s Series event.
The available evidence supports a clear, measured summary: Mamiko Tanaka is a Japanese former professional basketball player who played for Fujitsu Red Wave and became Shohei Ohtani’s wife in a marriage announced in 2024. The couple welcomed a daughter in 2025, while much of the rest of their private life has intentionally remained out of the public record.
