Mamiko Tanaka is a former Japanese professional basketball player best known today as the wife of MLB superstar Shohei Ohtani. She was born on December 11, 1996, in Tokyo, Japan, and is Japanese by nationality.
Growing up, Tanaka developed a passion for basketball at an early age. Thanks to her height, athletic ability, and dedication, she quickly became one of Japan’s promising young basketball talents. She attended Waseda University, one of Japan’s most respected institutions, where she continued to improve her basketball skills while balancing academics.
Standing approximately 5 feet 11 inches (180 cm) tall, Tanaka played as a forward and became known for her versatility, defensive skills, and teamwork. During her university years, she represented Waseda in national competitions before moving into professional basketball.
Although Mamiko Tanaka was already respected in Japanese sports circles, she gained worldwide attention only after Shohei Ohtani announced their marriage in February 2024. Despite the sudden fame, she has remained humble and largely stays away from the spotlight.

She joined the Fujitsu Red Wave, a professional team competing in the Women’s Japan Basketball League (WJBL). Playing as a forward, she earned praise for her rebounding, defense, and consistent performances. Her athleticism made her a valuable contributor to the team over several seasons.

In 2023, Mamiko quietly retired from professional basketball. Reports suggest she stepped away from the sport before marrying Shohei Ohtani, allowing her to begin a new chapter in life.
Because she values privacy, Tanaka has not pursued media appearances or endorsement deals following her marriage. Her estimated net worth is believed to be around $500,000 to $1 million, although no official figures have been confirmed.
