## Career
### 2023 : Mixed doubles champion, back to top 30, new career high and Elite Trophy

Kato won her major title in the mixed doubles at the 2023 French Open, together with her German partner Tim Pütz.
She reached a new career-high ranking of No. 27 on 23 October 2023, the week she was selected to participate in the 2023 WTA Elite Trophy with Aldila Sutjiadi.

#### 2023 French Open controversy

At the 2023 French Open, she and her partner Aldila Sutjiadi were defaulted in the women's doubles, after she accidentally hit a ball girl with a ball. She had to forfeit her points and prize money, although she made clear she would appeal the supervisor's decision. Kato received ample support from fellow players, including from the Professional Tennis Players Association, who deemed the disqualification unfair. Kato and Sutjiadi's opponents, Sara Sorribes Tormo and Marie Bouzková, were criticized for pushing the supervisor to disqualify Kato and laughing after the pair were disqualified, but did not apologize to Kato.

### 2024: Thailand Open doubles title

Kato and Sutjiadi won the doubles title at the Thailand Open, defeating Guo Hanyu and Jiang Xinyu in the final.

## Personal life and background

Kato has one brother named Yuki. She started playing tennis at the age of eight. She has stated that her tennis idols growing up were Justine Henin and Roger Federer. Her favorite surface to play on is hardcourt, but her favorite tournament is Wimbledon.
