Early life Takahashi was born in Kashihara, Nara, and began playing badminton in the second grade of elementary school. She trained with Kashihara Junior, where her mother was involved as a coach. Growing up alongside her older sister, badminton player Ayaka Takahashi, she felt pressure to match her sister's achievements and disliked being known simply as "Ayaka Takahashi's younger sister". This influenced her decision to attend different schools from Ayaka. In 2004, she won the girls' A division of the National Elementary School ABC Tournament.

Takahashi attended Wago Junior High School in Toyama, where she won the singles title at the All Japan Junior High School Championships in 2007.

Later that month, she secured a bronze medal at the Asian Championships in Taipei, where she lost to world number one Li Xuerui in the semifinals.

Takahashi later revealed that she had been close to quitting the sport, but was encouraged to continue by her sister's Olympic success and her encouragement for them to play and win together.

Takahashi returned to international competition in September 2016 at the Japan Open, progressing from the qualifying rounds to the quarterfinals before losing to China's Sun Yu. During the tournament, Takahashi said that she wanted to establish her own identity as a player rather than simply being known as Ayaka Takahashi's younger sister.
