Osaka, 20, shot to international fame on Saturday when she defeated 36-year-old American Serena Williams at Flushing Meadows to become the first Japanese player to claim a Grand Slam singles crown.
Nissan said the passionate video-game player and Beyonce fan would appear in global promotions and advertising, in something of a branding departure for a company whose popular GT-R sports car appeals mainly to men aged 40 and older.
Born in Japan to a Japanese mother and Haitian-American father and raised mainly in the United States, Osaka has won hearts on and off the tennis court as much for her ferocious serve as her down-to-earth humility.
Nissan joins a growing number of companies which have enlisted Osaka for endorsement, including Adidas AG, Yonex Co, Nissin Foods Co, Wowow Inc and Citizen Watch Co.
Osaka is the latest sports figure to lend her star power to Nissan, after Jamaican sprinter Usain Bolt served as the automaker's "global director of excitement" to promote the GT-R from 2012 to 2016.
Last year, it signed Australian actress Margot Robbie, who has been promoting its electric vehicles.
