Rei Sakamoto was born in Nagoya, Japan, into a family with a strong athletic background. Both of his parents were volleyball players, with his father having played at the collegiate level. This sporting environment undoubtedly influenced Sakamoto from a young age. Growing up, he was a multi-sport athlete, participating in swimming and even aspiring to be a baseball player, a sport immensely popular in his home country. However, it was on the tennis court that he felt an immediate and profound connection. Sakamoto has described a feeling of innate talent from the very first time he held a racquet, sensing that he was destined to excel in the sport. Recognizing his exceptional potential, his family supported his burgeoning tennis ambitions. A pivotal moment in his development came at the age of 15, when he made the significant decision to move to the United States to further his training. He enrolled at the prestigious IMG Academy in Florida, a world-renowned institution known for nurturing elite athletic talent. This move, supported by the Masaaki Morita Tennis Fund, placed him in the same pipeline as his idol, Kei Nishikori, and was instrumental in his rapid development, exposing him to top-tier coaching and competition from a young age. The transition to a new country with a different language and culture presented its own set of challenges, but Sakamoto’s determination and focus on his tennis career helped him navigate this period successfully.

He continued to build on this success in 2025, winning his second Challenger title at the Cary Tennis Classic in the United States. A third Challenger title followed in Yokohama, Japan, making him the first Japanese teenager ever to win three titles at this level. These victories propelled him up the rankings, reaching a career-high of world No. 159 on November 24, 2025.
