Painfully shy and with a mouth that moves so little she looks like a ventriloquist, Naomi Osaka is an unlikely advocate. In fact, were it up to her, Osaka would probably eschew her media commitments and luxuriate in playing her favourite video games.
Yet over the past year, Osaka, the No1-ranked women's tennis player who in press conferences can make a rabbit in the headlights appear positively self-assured, has become a beacon for emotional literacy and mental health awareness.
Judged by the numbers alone, the past 12 months have been a halcyon period for the Japanese, who grew up in the United States and has a Haitian father.
Flying up the rankings from No72 to the top spot and picking up two grand slams along the way, Osaka, 21, is ostensibly living the dream. She has found the journey difficult, however, and has been startlingly open in describing her struggles — especially over the past week following her shock split from coach Sascha Bajin.
Having first of all explained that she ended the hugely successful partnership with Bajin because, "I wouldn't put success over my happiness", Osaka expanded on the theme after losing to Kristina Mladenovic in Dubai on Tuesday.
