Yuika Onosaka, written in Japanese as 小野坂ゆいか, is a Japanese adult-video actress and gravure model. She is also known by the nickname “Onoyui” among fans.
As of July 2026, public agency and publisher profiles list her as a Japanese performer born on February 9, 2002. Her birthplace is commonly listed as Chiba Prefecture, Japan. Her height is listed as 164 cm. Her measurements vary slightly depending on the source, with her current agency profile listing B95(G) / W62 / H90, while some other official or publisher-related profiles list B97(H) / W62 / H100. For that reason, her cup size is best described carefully as being publicly listed between G and H cup, depending on the source.

Career Background
Yuika Onosaka made her AV debut with IdeaPocket in 2024. Her debut work is commonly listed as “FIRST IMPRESSION 174,” released in June 2024.
She first appeared as an exclusive actress for IdeaPocket. After her exclusive period ended, she became active as a non-exclusive, project-based AV actress. This type of performer is often called “kikatan” in the Japanese AV industry.
After becoming project-based, she appears to have worked at a very active pace across several makers. This helped raise her visibility among fans who follow new-generation Japanese AV actresses closely.
Personality and Public Image
One of the distinctive parts of Yuika Onosaka’s public image is her connection with illustration, manga, and creative interests. Public profiles list illustration as one of her hobbies, and tennis as a special skill.
Some public interviews and profile summaries describe her as someone who had an interest in adult manga before entering the AV industry. This background gives her a slightly different image from performers who entered the industry mainly through modeling, entertainment, or idol-style routes.
Among fans, she is often described as having a soft, cute facial impression combined with a curvy and mature body type. This contrast is one of the reasons she has attracted attention both in Japan and among overseas fans.
School Background and Student Days
Her exact school name, high school, university, or full educational background does not appear to be publicly confirmed through reliable sources.
What can be said safely is that some public profile sources mention that she was involved in art-related activities during her student days. Her interest in drawing and illustration also appears consistently in her public image.
Because school names and private educational details are not clearly confirmed, they should not be treated as verified public information.
Debut Motive and Entry into AV
Publicly available information suggests that Yuika Onosaka’s interest in AV was connected to her earlier interest in adult manga and sexual expression in fiction. This makes her debut story somewhat different from the standard “scouted as a beautiful girl” type of profile often seen in the Japanese adult industry.
However, as with many AV actress biographies, it is important to separate what has been publicly stated in interviews from what is only repeated on fan pages or anonymous websites. Her exact personal motivation should be described carefully unless quoting a verified interview directly.
Private-Life Topics
Some public interviews and profile summaries include personal anecdotes about romance and sexual experience. However, these are sensitive private-life topics, and not every reposted version online should be treated as reliable biography.
For a general public article, it is better to say that such personal stories have appeared in media interviews, while avoiding excessive detail or presenting every anecdote as independently verified fact.
I could not confirm reliable public information about her first love, first boyfriend, or whether her family and people around her know about her AV career. Unless she clearly states these matters herself in a public interview, they should be treated as unknown.
Representative Works and Catalog
Yuika Onosaka’s complete filmography is already large and continues to change as new titles are released. Her early career is strongly connected with IdeaPocket, where she debuted as an exclusive actress.
Representative early works include her debut title “FIRST IMPRESSION 174” and subsequent IdeaPocket releases during 2024. After becoming a non-exclusive performer, she appeared in works from multiple makers.
Because her catalog continues to expand, fans who want a full and current work list should check official maker pages, official sales platforms, and her own works-related announcements rather than relying only on repost sites.
Photo Book and Gravure Activity
Yuika Onosaka has also appeared in gravure-style media and photo-book projects. Her first photo book is commonly listed as “Yuika Biyori,” published by G-Walk.
Her gravure image emphasizes the contrast between her gentle, approachable face and her curvy figure. This combination has become one of her main selling points among fans.
SNS and Official Fan Routes
Yuika Onosaka’s main public social media presence is centered on X and Instagram.
Her commonly listed X account is @yuika_onosaka. Public profiles also mention related accounts, including a sub account and a works-information account.
Her Instagram account is also commonly listed under the handle @yuika_onosaka.
I could not clearly verify official TikTok, YouTube, Reddit, Xiaohongshu, Fantia, or OnlyFans accounts for her. Fans should be careful with unofficial repost accounts, impersonation accounts, and adult-content mirror pages.
Events and Fan Interaction
Yuika Onosaka participates in release events, fan events, photo sessions, and adult-industry appearances. These events are usually announced through official agency channels, event platforms, maker pages, or her own SNS.
For overseas fans, checking her official X account and agency profile is usually the safest way to follow event news and avoid fake information.
Fan Reputation
Yuika Onosaka’s fan reputation is built around several key points: her cute and soft facial expression, her curvy body type, her lively performance image, and her high activity level after becoming a non-exclusive performer.
Among Japanese fans, she is often appreciated as a new-generation actress with strong momentum. Among overseas fans, especially in Chinese-speaking fan communities, she has also gained recognition because of her distinctive look and energetic public image.
Overall, Yuika Onosaka can be understood as a rising Japanese AV actress who began as an IdeaPocket exclusive and then expanded her presence through a busy project-based career, gravure activity, events, and strong fan engagement.
