Wesley Nakashima, Brandon’s father, and Christina Nakashima, his mother, are both pharmacists.
Brandon was born in San Diego, California, on August 3, 2001. Bryce, his younger brother, is his name.
He has a Japanese last name, and both of his parents were born in the US. When Brandon was just three years old, his Vietnamese maternal grandfather introduced him to tennis.
Even though he has a two-handed backhand, Roger Federer is his preferred tennis player.
In Delray Beach, Florida, in February 2020, he participated in his first main draw after being awarded a wild card.
He beat Ji Vesel and Cameron Norrie to go to the quarterfinals, where he fell to Yoshihito Nishioka.
