While Osaka plays for Japan, she has lived and trained in the US since she was very young. Because her mother is Japanese and her father is Haitian, Osaka knows at least a little bit of three different languages: English, Japanese, and Creole, which she learned from her paternal grandparents. Still, she prefers to respond to questions in English during interviews, as it's the language she's most confident speaking — and as the New York Times reported, she's too shy and too much of a perfectionist to take any chances.
