Is Shohei Ohtani Married?

The Short Answer: Yes, Married to Mamiko Tanaka

Yes — Shohei Ohtani is married. The two-way superstar, born July 5, 1994, in Oshu, Japan, announced his marriage on February 29, 2024, in an Instagram post written in both English and Japanese. He did not name his wife at the time, describing her only as "a normal Japanese woman" who is "very special to me" — but fans quickly identified her as Mamiko Tanaka, and Ohtani later posed for photos with her, confirming it.

Tanaka, 28, is a former professional basketball player who competed in Japan's W League — the country's top women's competition — as a forward for the Fujitsu Red Wave from 2019 to 2023. She stands 5-foot-11, and her athletic background is part of what drew the couple together: reports indicate they crossed paths in Japan through shared sports training circles before Ohtani joined the Dodgers.

The marriage announcement came just weeks after Ohtani signed his historic 10-year, $700 million contract with the Los Angeles Dodgers — making the spring of 2024 a double new chapter: new team, new marriage. As of October 2026, the couple has two children and remains famously private.

Shohei Ohtani and Mamiko Tanaka: Relationship Timeline

The through-line is privacy: a secret courtship, a private ceremony (details never disclosed), children whose names are never shared. Ohtani said in his announcement that he doesn't "really feel comfortable talking about when I got married exactly" — and he never has.

Who Is Mamiko Tanaka? The Athlete Behind the Privacy

Mamiko Tanaka is not a celebrity spouse who married into sports — she is sports. Born in Japan, she played four seasons (2019–2023) as a forward for the Fujitsu Red Wave in Japan's Women's Basketball League, one of Asia's most competitive professional leagues. At 5-foot-11, she was a physical presence on the court, and her retirement from basketball in 2023 coincided with the period when her relationship with Ohtani became serious.

Her first major public appearance as Ohtani's wife came at the 2024 Paris Olympics, where international cameras finally got a clear look at her. Coverage noted her composure under intense scrutiny — and, more importantly, treated her as a person with her own athletic credentials rather than a footnote. She has since appeared at select Dodgers events: the 2024 NL West celebration, the 2026 MLB awards circuit.

The couple shares their home with Decoy, Ohtani's beloved dog — a Kooikerhondje who has become a celebrity in his own right, throwing out a first pitch at Dodger Stadium. Ohtani's marriage announcement notably included the dog: "the two of us (and one dog) will work together." As of October 2026, the household is two athletes, two children, and one very famous dog.

Two Kids: The Daughter (2025) and the Second Child (2026)

Ohtani and Tanaka welcomed their first child, a daughter, in April 2025. Ohtani announced the birth on Instagram with a message thanking his "loving wife," his daughter (for making them "very nervous yet super anxious parents"), the Dodgers organization, and the medical professionals. True to form, the couple did not share the baby's name or birth details.

The second child arrived on June 20, 2026 — announced the same way, via Instagram, with a photo of the newborn swaddled in a blue blanket. The timing was pure Ohtani: he missed the Dodgers' June 19 game against the Baltimore Orioles, with the team listing him as away on paternity leave, then shared the news himself the next day. Fans had noticed the absence; the explanation — "this adorable tiny human," as one outlet put it — was worth it.

As with everything in this marriage, details are minimal: no names, no genders confirmed for the second child, no family photoshoots. The children exist in Ohtani's public narrative as "the little rookie" (his phrase for the first pregnancy announcement) and as the reason Dad missed a game — and that is exactly how the couple wants it.

The Private Ceremony: What We Know (and Don't)

Here is what is known about the Ohtani-Tanaka wedding: almost nothing. The couple married in a private, family-only ceremony — no venue announced, no date confirmed beyond the general timeframe, no photos released. Ohtani announced the marriage on February 29, 2024, but the ceremony itself predates the announcement by some weeks; he has said he is uncomfortable specifying exactly when it happened.

This is consistent with Ohtani's entire approach to his personal life. During six seasons with the Los Angeles Angels, he never publicly dated anyone; the marriage announcement blindsided even seasoned baseball reporters. The Dodgers' 2024 season — his first in Los Angeles, the 50/50 season (50 home runs, 50 stolen bases), the World Series title — played out with Tanaka present but never performing: she attended, she celebrated, she did not give interviews.

For a player of Ohtani's magnitude — the face of baseball, a $700 million man — to keep his wedding entirely private in 2024 is almost unprecedented. It required discipline from the couple and, notably, cooperation from the Japanese and American press, who largely respected the boundary. The result: one of the most famous marriages in sports has no wedding photos, and that is by design.

2026: Back-to-Back Titles and a Growing Family

As of October 2026, the Ohtani household is living a charmed double life. On the field, Ohtani's Dodgers are the reigning back-to-back World Series champions (2024 and 2025, the latter a 4-3 thriller over the Toronto Blue Jays) — the first repeat champions since the late-1990s Yankees. Ohtani won his third straight National League MVP award for the 2025 season, hitting a career-high 55 home runs while returning to the mound (1-1, 2.87 ERA in 14 appearances) after elbow surgery.

Off the field, the family has doubled: a daughter born April 2025, a second child born June 2026. Tanaka was by his side at the January 2026 BBWAA Awards Gala, where Ohtani collected his MVP — one of her handful of public appearances, each one noted precisely because they are so rare.

For "is Shohei Ohtani married": yes — married to Mamiko Tanaka since February 2024, with two children, in a marriage conducted almost entirely out of public view. The most scrutinized player in baseball has built the least scrutinized marriage in sports — and as of October 2026, both the titles and the family keep coming.
