50 free Naomi Osaka trivia questions with answers — sports quiz, new questions added Aug 2026.
Naomi Osaka was born in Osaka, raised on Long Island and in Florida, and coached by a father who copied Richard Williams's plan after watching the 1999 French Open. She skipped the junior circuit entirely, upset Sam Stosur at 16 on her WTA debut, and by 2019 was the first Asian player to be ranked No. 1 in singles after back-to-back titles at the US Open and the Australian Open. This quiz spans the whole story: the bittersweet 2018 final against Serena, the seven masks of the 2020 US Open, the Olympic cauldron in Tokyo, the French Open press-conference stand and the break that followed, the birth of her daughter, and the comeback that brought a first clay title in Saint-Malo, a first Wimbledon quarterfinal and a win over a world No. 1 on grass. Off court there are the Yonex rackets, the Nissin ad, Evolve, Hana Kuma and the NWSL stake. Fifty questions, four options each, with a short explanation after every answer.
