2024

Sugihara worked with a leotard manufacturer to design a new leotard, which she dubbed the "Aitard" after herself and debuted in competition. The leotard has a lower cut, with fabric extending to the top of the legs, and is based on the attire worn by men's aerobic gymnasts. Sugihara said that while she had not minded wearing high-cut leotards when she was younger, as she grew older, she began to have concerns about wearing them, and photographs of her in leotards had received sexual comments online. She was inspired to create a new leotard design after the German women's gymnastics team competed in unitards at the 2020 Summer Olympics and after a male employee of hers suggested creating a new gymnastics outfit for parents who did not want their children wearing revealing leotards. The new leotards conform to International Gymnastics Federation rules.^[49]

Ahead of the NHK Trophy in May, she said that she was trying to focus on herself and enjoy the competition rather than thinking of qualifying to the 2025 World Championships team, as she felt she had not performed as well as she wanted to at the previous year's NHK Trophy due to focusing on making the Olympic team.^[54] Ten years after her first NHK Trophy victory, she won the all-around for a second time, just .033 points ahead of Rina Kishi. The result gave her a place on the World Championships team.^[55]
