Name: Rina Sawayama

Age: 27

Hometown: Niigata, Japan

Now Lives: In a split-level home in Southwest London that she shares with four friends.

Claim to Fame: Ms. Sawayama is a model and musician whose catchy pop anthems examine millennial relationships with social media and technology. She uses her Instagram to speak out about the lack of Asian representation in fashion and music, and to open up a dialogue about the pressures of social media with her followers.

“Social media creates a really skewed measure of aspiration that you feel like you have to reach every time you log on to Instagram,” she said. “I want to make people feel less alone.”

Big Break: In 2017, a few years into her modeling career, Ms. Sawayama was inspired by James Scully, a casting director, who spoke out about model mistreatment and racism at castings for Balenciaga and Lanvin’s fall presentations.
