According to reports, Osaka brushed off comments made by Japanese comedians two weeks ago, who said she was "too sunburned" and "needed some bleach". "I think that will be one of the most memorable things that ever happens to me".
She added to her maiden US Open title last year by winning the Australian Open in January and recently picked up her third championships of the year by winning the China Open in Beijing.
Osaka won the China Open on Sunday and is now the No. 3-ranked women's singles player in the WTA.
Osaka added she desires to objective for the gold though she can be nervous as expectations will likely be excessive.
Osaka, who will turn 22 next week, plays under the Japanese flag in Women's Tennis Association events and the Fed Cup.
In July, in an interview with the International Tennis Federation, she said: "Winning gold in Tokyo is something that I have dreamed about".
