Naomi Osaka is sharing her story in her self-titled Netflix docuseries, and as a result, we're getting some rare peeks into the 23-year-old tennis player [1]'s personal life. In addition to some cute glimpses of her relationship with rapper Cordae [2], we also see her close bond with her older sister, Mari Osaka [3]. Just like Naomi, Mari is an experienced tennis player. The 25-year-old made her WTA Tour debut in 2014, then retired in early 2021. While the two have shared the tennis court from time to time, including in a doubles match at the Pan Pacific Open in Japan in 2017, they are a close duo off the court as well. The sisters have shared some adorable snaps together on their Instagram accounts over the years. See some of their sweetest sisterly moments ahead.
