Shizuoka City native Hirose Suzu was born four years following her model and actress sister, Alice Hirose. Her real name is Ooishi Suzuka, but she chose her alias to synchronize with her older sister. She played basketball at high school. She was scouted when her mother and she attended an event for Seventeen magazine for which her sister modelled. She was a model for Japan’s Seventeen magazine beginning 2012. She began her on-screen career in 2013, but it was her role in 2015’s Umimachi Diary (a.k.a. ‘Our Little Sister’) next to Haruka Ayase that got her noticed. The film, which was shown at the Toronto International Film Festival, was nominated for multiple awards in Japan. Hirose won the Newcomer Of The Year award at the Japan Academy Awards. She was in another film by Hirokazu Koreeda two years later, namely The Third Murder, which was also showcased at TIFF in Canada.
