​Personality and Appearance

​During her career as an adult video actress, she mostly maintained long hair, although she did appear with short hair in some of her early works.

​Charm and Specialty
​Yaya Kouzuki’s primary charm lies in the alluring sexiness that emanates from her beauty. Even when she is not nude, she exudes a sexy aura that captivates her fans. Her specialty is pole dancing, which she also performs in some of her films.

Early Life and Sex Service Career
When she was 14, toward the end of her second year in junior high school, Yaya Kouzuki was picked up by a man who forced her to have sex for the first time and taught her how to give oral sex.
She never attended high school. At the age of 16, she married a man three years her senior, and at the age of 17, on December 25, 1992, she gave birth to a son. She divorced him at age 18 due to his domestic violence and became a single mother.
​Starting around 1993, at the age of 18, she worked as a sex worker at the famous sex service shop, "Hiratsuka Janjan," using the name Minami. The service price was 10,000 yen. At her peak, she earned several million yen per month, with the money primarily going toward repaying her ex-husband's debts.
​Her beauty and exceptional fellatio skills immediately made her the most popular girl at Hiratsuka Janjan, resulting in long lines of customers waiting for her. Yaya Kouzuki is known for her highly pleasurable blowjobs—skills that were genuinely honed in the sex service shop, not merely for show. On busy days, she was reportedly able to make 37 penises ejaculate through fellatio within the five hours between the shop's opening and closing.
​As her popularity grew as an "idol" in the sex service industry, she eventually began appearing in nude gravure photography.

Early Career, Name Changes, and First Retirement
Yaya Kouzuki debuted in adult videos at the age of 20 with the film “Lips of the Muse” (produced by Athena Eizo). She initially appeared in two films under the stage name “Minami Hoshino,” a name inspired by her employment at a sex service shop. She then changed her stage name to “Yaya Kouzuki,” a name given to her by her agency senior and godmother, Kyoko Aizome.
​In 2000, she temporarily retired from being an adult video actress. She adopted the stage name “Eri Hayashi” and appeared in mainstream works such as V-cinema. She soon returned to the adult video industry and continued to appear in films, primarily by indie-style producers, until 2003.

Second Retirement and Personal Interlude
​Yaya Kouzuki retired for the second time in January 2003 with the film “Garden of Bondage” (produced by Next Group).
​Following her second retirement from adult videos, Yaya Kouzuki opened the pub “Lunaire Fairy” in Odawara City, Kanagawa Prefecture, on March 12, 2004. However, the pub closed abruptly on July 6, 2004.
​She began a romantic relationship with a man she met at the pub, but since he was married, the relationship was an affair. Although he promised to “leave his wife,” he ultimately did not divorce her, and Yaya Kouzuki never married him. She obtained her motorcycle license in July 2006 and has experience organizing weekend group rides to interact with her adult video fans.
From December 14, 2007, through September 2009, she taught pole dancing to the hostesses at 'Club Magic'—a hostess club in Hiratsuka, Kanagawa—while also producing and starring in her own weekly shows every Friday, Saturday, and Sunday, during which time she even gave two striptease performances.

The 2008 Comeback and Physical Transformation
Yaya Kouzuki made her comeback to adult videos with “Comeback! Yaya Kouzuki” (produced by Max-A), released on December 5, 2008. In this film, she resumed performing actual intercourse.
​Following her 2008 return, Yaya Kouzuki underwent a significant physical transformation through pole dancing and intensive gym training, resulting in a more muscular and voluptuous physique. Her toned body, beautiful legs, and sexy backside became even more striking, leading many to consider her even sexier now than she was in her twenties when she first debuted. In her personal life, she remarried on July 31, 2009, only to divorce a few months later on December 25.

International Popularity and Final Retirement
​As her popularity soared overseas, a three-day, two-night AV promotional event was held in Taiwan starting April 25, 2009. Yaya Kouzuki was featured prominently in the Taiwanese media and gained immense popularity among local fans.
​Yaya Kouzuki retired again on March 7, 2010, with her final work, “Raped in Front of Her Husband” (produced by Attackers). She was beloved by many fans and deeply missed upon her retirement.

Accolades: The "Fellatio Queen" Title
​Adding to her accolades, Yaya Kouzuki ranked first in an adult video magazine's survey titled “AV Actors' Choice: Top Actresses for Fellatio,” an achievement that earned her the title of "Fellatio Queen."

Career Highlights and Signature Scenes
Yaya Kouzuki is featured in several notable films where large amounts of semen are ejaculated onto her face and body by multiple male performers, scenes which are highly popular and exciting for her fans. These films include Gekisha Vol. 10 (produced by Audaz Japan), Dream Shower Vol. 34, and VIP Shower Vol. 2 (both produced by Waap Entertainment).

Authenticity of Sexual Content
​In her first two films, released under the stage name Minami Hoshino, she performed actual intercourse.
​However, during the period between when she adopted the name Yaya Kouzuki and her return to the industry in 2008, the films released as Yaya Kouzuki generally did not feature genuine vaginal penetration by an adult video actor; these scenes were simulated.
​Since her 2008 return, Yaya Kouzuki has typically performed real sex scenes in her work. The MAX GIRLS series (produced by Max-A) is a notable exception, as the sex depicted in those films is simulated. All her other works since 2008 feature genuine sexual intercourse.

Uncensored Works Circulation
​In 2020, AI-edited, uncensored versions of Yaya Kouzuki's previous works, which had originally been released with mosaics, began to circulate. This allowed her fans to view scenes featuring her vagina and blowjobs without the mosaic censorship.

Comprehensive Japanes Fan Evaluation: Yaya Kouzuki

Key Strengths and High Ratings from Fans
Beauty and Visuals: Fans consistently describe her as a "peerless beauty" with a "perfect face," highlighted by her clear, pale skin and the captivating contrast between her cool elegance and her warm smile. Her popularity stems from her exotic, quarter-American appearance, and she has been praised throughout all phases of her career—from the fresh youthfulness of her early days (as Minami Hoshino) to the allure of her prime and the mature sensuality of her comeback. The most common fan comments are that "her face alone is enough to get me going" and "she's so beautiful I get turned on."

Fellatio Technique: This is her biggest selling point. Her blowjobs are universally rated as "divine," thanks to seasoned professional technique honed from her experience as a former sex worker, cementing her status as top-tier in the industry. Her vast repertoire—including intricate, sticky tongue work, vacuum fellatio, glans licking, ball licking, continuous fellatio ejaculation, and post-ejaculation "cleaning" fellatio—has earned her a reputation for exciting even those who aren't particularly into blowjobs. Her performances in Fellatio Venus (produced by Premium) and Dream Shower No.34 (produced by Waap Entertainment) are especially celebrated.

Bukkake/Facials: The sight of massive amounts of semen covering her beautiful face is praised as strikingly beautiful, creating an irresistible "gap" between her usual refined appearance and her cum-drenched look—an impactful scene that fans say will go down in AV history. She is regarded as the pinnacle of bukkake actresses, with standout works including Dream Shower No.34, VIP Shower 2, STAR BOX Semen Edition (all from Waap Entertainment), and Gekisha Vol.10 (Audaz Japan).

Slutty/Aggressive Play: She is praised for taking the lead by teasing men with provocative gazes, sultry upward glances, dirty talk, and skilled handjobs.

Divided Opinions and Points of Dissatisfaction
Acting and Orgasm Performance: Early in her career, her acting was often criticized as "indifferent" and "inauthentic." Although her eroticism intensified dramatically after her comeback, her performances in SM scenes and simulated orgasm sequences generally received only mediocre reviews.

Unimpressive Insertion Scenes and Lack of Intense Sex Play: Her strong image as a skilled fellatrix frequently led fans to find her actual penetration scenes underwhelming. Additionally, some viewers felt she had "fallen behind the times" due to never appearing in any uncensored works. Her comeback project also drew criticism from longtime fans over her body shape and the directorial choices. There was further widespread disappointment that she never swallowed semen on camera.

Other Issues: Additional complaints included contrived moaning during sex scenes and an overreliance on handjobs leading to ejaculation.

Overall Fan Consensus
Classic and Essential Works: Must-see titles for fans of blowjob, bukkake, and slutty genres include Dream Shower No.34 and the STAR BOX series (both from Waap Entertainment), Lips of the Muse (Athena Eizo), Fellatio Venus, Premium Soap, and Yaya Kouzuki Supports Your Masturbation Time (the last three from Premium).

Fan Base: She continues to enjoy strong, passionate support from dedicated blowjob enthusiasts, bukkake fans, and admirers of her beauty.

Overall Rating: She is widely regarded as a “legendary actress who will go down in AV history” thanks to her rare triple threat of stunning beauty, exceptional blowjob skills, and bukkake performances. The general consensus is that only the mosaic censorship and the technical limitations of her era kept her from achieving a perfect score.

Current Status: Despite having retired multiple times, there remains considerable fan demand for another comeback. Her existing works is currently being rediscovered and appreciated anew through AI-enhanced remastering.

Conclusion: There's a general consensus that Yaya Kouzuki has top-notch practical skills but isn't particularly strong at performing impressively on camera. Nonetheless, she enjoys unwavering popularity as an overwhelmingly memorable actress, thanks largely to her stunning beauty and exceptional blowjob techniques.

​Yaya Kouzuki’s Personal Blogs and Evolving Sexual Philosophy
​On her blogs, Night Visitor and YAYA STYLE NETWORK, Yaya Kouzuki documented her upbringing, her career in sex work and adult films, and her personal life.
​She shared her views on sexuality, initial believing that romantic love and physical intimacy were deeply interconnected. While she fully expressed her sexuality in her adult video roles, she originally viewed her private persona as reserved rather than sexually active. However, as time went on, she acknowledged in a September 2006 entry that her initial self-perception was mistaken, realizing that her true disposition was actually far more sexually adventurous.

Yaya Kouzuki’s Thoughts and Personal Experience on Swallowing
Although Yaya Kouzuki acknowledges that semen itself tastes unpleasant, she interprets the act of swallowing—often depicted in adult videos—as a way to confirm and deepen mutual love. Having tried it herself in the past, she was shocked by the intense sensation, distinct bitterness, and overwhelming smell. She vividly remembers the experience, including her desperate effort to hide her discomfort out of consideration for her partner, as well as how terribly popcorn tasted when she ate it right afterward to cleanse her palate.

Business Strategy and Growth at Hiratsuka Janjan
While performing at Hiratsuka Janjan, Yaya Kouzuki adopted a unique strategy to stand out in a competitive market. She provided fully nude service to clients, which significantly increased her request rate and earnings. This success ultimately opened doors to adult magazine appearances and greatly boosted her self-confidence.
