The tennis star revealed that Shai means 'God's gift' and said she chose the name because she wanted her daughter to always feel like a true blessing. Shai's father is American rapper and Grammy-nominated artist Cordae. Although Osaka and Cordae split amicably in 2025 after six years of dating, they continue to co-parent Shai. When announcing their split, the former world No. 1 expressed her gratitude for their time together and praised Cordae for being an amazing father to Shai. 'He's a great person and an awesome dad. Honestly, I'm really glad our paths crossed because my daughter is my biggest blessing and I was able to grow a lot from our experiences together,' she wrote. Osaka has also spoken about the important role her daughter plays in her life. She has made it clear that being a mother comes before being a tennis player. 'My most important role is not that of a player, but that of a mother to my daughter.' Copyright 2026 The Arena Group, Inc.
