In July, Osaka announced that she and her sister Mari had designed a limited-edition mask, with all proceeds benefiting UNICEF Japan's COVID-19 relief efforts. It was hardly her first foray into fashion — in February, she had debuted her first collection at New York Fashion Week, which was designed in collaboration with Hanako Maeda's ADEAM fashion house. "I've always really loved clothes," she told Vogue. Compared to her endeavours in tennis, which require a lot of discipline, fashion feels like an escape. "It's relaxing not to have to go into fashion in such a super-serious way, and to feel really creative and free," Osaka said.
