It follows her exit at The US Open.
Naomi Osaka says she will take another break from tennis after the defence of her US Open title ended at the third round stage.
The world number three lost in three sets to 18-year-old Leylah Fernandez.
Osaka withdrew from the French Open back in May after revealing she has been struggling with her mental health since becoming a Grand Slam champion in 2018.
The 23-year-old also missed Wimbledon before returning to the sport at the Tokyo Olympics
