Early Life and Background
Chisato Iwai was born and raised in Saitama Prefecture, a region on the Japanese main island of Honshu known for producing talented athletes across many sports. She first picked up a golf club at the age of eight, an early start that laid the foundation for a career marked by consistent progress through junior and amateur ranks.
As a junior golfer, Iwai demonstrated her potential by winning the Golf Digest Japan Junior Cup on two occasions, establishing herself as one of the standout young amateurs in her country. Her twin sister, Akie Iwai, also pursued golf at a high level, and the two have continued to share a competitive bond as professionals. This family connection to the sport helped shape Iwai’s path toward a professional career.
Path to Golf
Following her junior success, Iwai transitioned into the amateur ranks where she continued to refine her game against stronger competition. Her consistent results confirmed that she possessed the talent to compete professionally, and at the age of 18 she made the decision to join the paid ranks. In 2021, she turned professional and immediately joined the LPGA of Japan Tour, the premier women’s golf circuit in her home country.
Her rookie year on the main tour included a victory on the Step-Up Tour, the developmental circuit affiliated with the LPGA of Japan Tour. That early win signaled her readiness for the larger stage and gave her valuable experience competing week in and week out as a professional. By the end of her first season, Iwai had already established herself as a rising talent within Japanese women’s golf.
