Los Angeles Dodgers star Shohei Ohtani is one of the most notable athletes in the world, but his wife Mamiko Tanaka prefers to keep a low profile. Tanaka is no stranger to Dodgers games amid the team’s World Series run, but she does not have a sizable social media presence where she shares constant updates.
Ohtani surprisingly announced the couple was married via a 2024 Instagram post. The Dodgers star declined to provide many details about the particulars of their relationship.
Tanaka accompanied Ohtani to Atlanta during the 2025 MLB All-Star Game festivities. Ohtani’s posts from the weekend did not include Tanaka’s face as the couple prioritizes their privacy.
“She is a Japanese woman,” Ohtani said during a February 29, 2024, media session after announcing the couple’s marriage, per Associated Press. “I don’t really feel comfortable talking about when I got married exactly, but she’s a normal Japanese woman.”
Here’s what you need to know about Ohtani’s wife.

Ohtani is not the only athlete in the family. Tanaka is a former pro basketball player who suited up for the Japanese team Fujitsu Red Wave in the Women’s Basketball League. Ohtani’s wife played forward for four seasons in the WBL, per ESPN’s Brianna Williams.
“She signed with the Red Wave in 2019, and the team finished the regular season with a 13-3 record,” Williams wrote in a March 14, 2024, article titled, “Shohei Ohtani shares first photo with wife, Mamiko Tanaka.” “The Red Wave’s most successful season during Tanaka’s tenure came in 2021.
“They finished the regular season 17-3, including an 11-1 home record to secure a postseason berth. They won the quarterfinal and semifinal rounds, but were swept in the final. Tanaka shot 47.7% from the field and 69.9% from the free throw line in 28 games last season.”
Shohei Ohtani Surprisingly Announced He Was Married to Mamiko in a 2024 Instagram Post
Back in 2024, Ohtani made it simple by posting a text block on Instagram revealing that the couple is married. It was a bit of a surprise as Ohtani was not known to be in a relationship at the time.
“To all my friends and fans throughout, I have an announcement to make: Not only have I (begun) a new chapter in my career with the Dodgers but I also have (begun) a new life with someone from my Native country of Japan who is very special to me and I wanted everyone to know I am now married,” Ohtani explained on Instagram in 2024.
“I am excited for what is to come and thank you for your support.”
Shohei Ohtani Signed a Historic 10-Year, $700 Million Contract With the Dodgers
Ohtani signed a historic 10-year, $700 million contract with the Dodgers ahead of the 2024 MLB season, but the majority of the two-way star’s money is deferred until after the deal expires. The Dodgers superstar is not just one of the top MLB players, but a historic athlete who is the rare combination of an elite hitter and pitcher.
Despite his rising stardom, little is known about Ohtani’s life away from baseball. Ohtani earned an estimated $102 million in 2025, per Sportico, proving that sometimes less is more when it comes revealing details about his personal life.
