Early Career and Industry Breakthrough
Born in Miyazaki Prefecture, Ayu Sakurai began her professional journey after being scouted while residing in Osaka. She entered the adult video industry in March 2013 under Prestige, quickly distinguishing herself by branding as a 'chippai actress' who highlighted her small bust as a unique selling point. Her early years were defined by independence; she worked as a 'Kikatan,' an unaffiliated performer, which allowed her to build a substantial portfolio before securing exclusive contracts. In 2014, her momentum surged with nominations for the DMM Adult Award and significant recognition at the Weekly Asahi Geinō AV Grand Award, where she earned the Excellent Actress title alongside Minami Kojima and Aika Yumeno. That same year, she ranked in the top ten across multiple sectors in DM14.R18's annual rankings, solidifying her status as a leading figure before transitioning to an exclusive contract with Million in September 2015.
Idol Group Success and International Exposure
In early 2015, Sakurai expanded her career beyond traditional adult films by joining the idol group Million Girls Z. This marked a pivotal shift into mainstream entertainment, where she participated in terrestrial television programs on Tokyo MX and released music singles like 'I ♥ MGZ.' Her role within the group extended to live performances across Asia, including events in Shanghai, Guangzhou, and Macau during their 2015 tour. These international appearances showcased her versatility as a performer capable of engaging diverse audiences outside the adult industry. During this period, she also achieved notable accolades such as the MVP title at a swimming tournament and the Best Performance Award at the Sexy Idol Music Festa. Her involvement in MGZ demonstrated a strategic effort to bridge the gap between adult entertainment and idol culture, leveraging her popularity to secure roles in major events like the Asian Adult Expo.
Transition to Mainstream Acting
Despite her success in adult media, Sakurai consistently expressed a desire to transition into non-pornographic acting. She officially retired from the AV industry in 2016 after releasing over 800 productions, initially adopting the stage name Yoshimi Sakurai for her post-retirement activities. Her shift to mainstream entertainment included diverse roles in short dramas on TikTok, comedic sketches on YouTube, and dramatized promotional videos. On stage, she took on significant characters in various theatrical productions ranging from 'Mukenjigoku' to 'Yasashii Akuma,' proving her adaptability as a dramatic actress. By 2017, she began performing under her original name again at overseas events, signaling a full rebranding toward civilian life while maintaining her connection to performance arts through theater and independent film projects like the R15+ movie 'Blue Porno / Tokyo Gate Bridge.'
Gaming Roles and Cultural Impact
Sakurai's influence extended into the video game sector, most notably with her casting in 'Yakuza 0' released in 2015. In this high-profile title, she portrayed Ayu, a timid young woman aspiring to become a dominatrix, a role that brought her character to millions of players worldwide. This appearance was significant as it represented one of the few instances where an adult film actress secured a prominent voice and motion capture role in a major AAA game franchise. Her inclusion in such a widely recognized title helped normalize the crossover between adult entertainment performers and mainstream gaming culture. Additionally, her participation in various industry awards and expos, including the Japan Adult Expo and events in Macau, highlighted her status as a cultural icon who successfully navigated multiple entertainment spheres before establishing herself as a legitimate stage and screen actress.
