Rinka Mizuhara

Before entering the adult industry, Mizuhara built a career as a fashion model in Kyoto, working with an agency in Osaka. She appeared in catalogs, local department store advertisements, and fashion shows. At 25, she married a man 14 years her senior, and by the time of her AV debut, she had been married for 10 years and was balancing work with raising two children. She describes her relationship with her children as being "like friends," and notes that she sometimes feels out of touch with other mothers who focus heavily on education. Despite her career, she leads an ordinary housewife's life, avoiding expensive spas and special beauty treatments. She believes the secret to staying youthful is simply "keeping a young mind."

Mizuhara's decision to enter AV was driven by both a scouting offer and personal circumstances, including a sexless marriage lasting over three years. She wanted to reclaim her femininity without cheating on her husband, so she entered the industry without telling him. She describes herself as having a masochistic and somewhat clingy personality, and she enjoys intense scenes with strong contrast. In her debut work, she actively requested group scenes and hard content, wanting to release long-suppressed desires. Around November 2016, she became an exclusive actress for Attackers, and from 2017 she also appeared in works for LEO, h.m.p., and several uncensored titles. Although her total number of releases was modest, around 40, she gained popularity as one of the top mature actresses, known for her strong desire to please fans, often writing lengthy Twitter replies. Around 2020, new title releases slowed dramatically. Her agency profile and Twitter account were later deleted, sparking rumors of retirement, but no official announcement has been made.
