Shohei Ohtani, the global baseball superstar known for his laser focus on the field, has embarked on an exciting new chapter of his life off the diamond. In a relatively short time, the Los Angeles Dodgers phenom has transitioned from one of the most eligible bachelors in sports to a married man and, more recently, a new father. While he fiercely guards his private life, Ohtani has shared some joyful details with his fans, offering a glimpse into the family that now occupies his world beyond the ballpark. It’s a story that blends his characteristically quiet demeanor with moments of public celebration for his biggest life milestones.
The man who makes history every time he picks up a bat or ball has also been making personal history, building a life with his wife, Mamiko Tanaka. Their story is one of quiet connection, shared understanding, and a mutual respect for privacy. For a player whose every professional move is scrutinized, Ohtani has managed to keep the narrative around his relationship and marriage remarkably grounded. The journey from a surprising announcement to the arrival of their first child has been a captivating subplot to his already legendary career, showing a more personal side of the two-way superstar.
A Private Union with Mamiko Tanaka
Shohei Ohtani set the sports world abuzz when he announced his marriage in February 2024. He revealed the news on Instagram, sharing that he had “begun a new life with someone from my native country of Japan who is very special to me.” In his typical fashion, he initially kept the identity of his bride private, though he did playfully mention they were hoping to move forward with their fans alongside “the two of us (and one dog).” It wasn’t long before his wife was identified as Mamiko Tanaka, a former professional basketball player who had played for the Fujitsu Red Wave in Japan’s Women’s League.
As more details emerged, a picture of their relationship began to form. In a rare and candid interview, Ohtani shared that Tanaka is two years younger than him, putting her at 28 years old to his 30. He described a comfortable and natural connection, explaining that they can be themselves around each other without having to change how they speak or act. Their quality time often has a modern, long-distance twist; during his baseball season, they would often watch Netflix shows like the Japanese drama VIVANT together over the phone, pressing play at the same time to share the experience.
The couple’s love story reportedly began after several chance encounters at a training facility, a place Ohtani recalls clearly, even if he doesn’t remember their very first greeting.
Welcoming a New Teammate: The Ohtani Family Grows
The family expanded in April 2025 when Shohei Ohtani and Mamiko Tanaka welcomed their first child, a baby girl. The Dodgers superstar announced the happy news on Instagram, temporarily stepping away from the team as he was placed on the paternity list. His post was filled with gratitude and the typical nerves of a new parent. “I am so grateful to my loving wife who gave birth to our healthy, beautiful daughter,” he wrote. “To my daughter, thank you for making us very nervous yet super anxious parents.”
While the couple has chosen to keep their daughter’s name out of the public eye, Ohtani has given fans a few precious glimpses into his new role as a father. For Mother’s Day, he posted an adorable photo of their three hands together—his, Tanaka’s, and their newborn’s—in a touching tribute to his partner. The arrival of his daughter has even become a fun talking point in baseball circles, with fans and analysts joking about his newfound “Dad strength” as he continues to dominate on the field.
