How Shohei Ohtani and Mamiko Tanaka Met

Shohei Ohtani and Mamiko Tanaka's relationship shows how top athletes often connect. They share a Japanese background and respect each other's sports careers. They were introduced by friends in Japan's sports world in 2022 and their relationship grew in private, away from the media.

On February 29, 2024, Ohtani shared a private moment publicly. He used Instagram to announce he was married, showing a photo of their joined hands with wedding rings.
