Kojima Minami: 15 Years, 3 Labels, 589 Works

Who is Kojima Minami?

July 2011, age 18. The girl who first stood in front of the camera as an exclusive Alice Japan performer continues, now at 33 in 2026, to shoot at a pace of one film per month.

589 works total. Three different labels under her name. A singer in a music unit. Owner of a dog harness brand. Appearing in terrestrial television commercials. The title “AV actress” alone cannot capture the scope of her 15-year career.

Standing at 150 cm with an E-cup, her unique physical proportions create a distinctive presence on screen. The contrast between her delicate frame and generous bust has remained the core of her visual appeal throughout her 15-year career. In her Instagram posts, she self-analyzes her personal color as “spring warm tone” and her bone structure type as “soft elegance,” revealing her high awareness of visual presentation.

Alice Japan Era (2011–2014)—Origins of the Pure Image

Age 18, Debut

On July 8, 2011, Alice Japan released “True Beautiful Girl: Kojima Minami.” A petite 150 cm frame with a youthful appearance belying her age. She fit perfectly into Alice Japan’s specialty of “innocent beautiful girl” content of that era.

She maintained a high pace of one film per month in her debut year. July 2012 marked her one-year anniversary release, followed by a two-year anniversary work in July 2013. Her solo output during the Alice Japan period totaled approximately 30 films. Her early trademark was a sweet anime-like voice and a carefree smile toward the camera.

Icon of Purity

During this period, titles frequently featured keywords like “beautiful girl,” “school,” and “academy.” The lane Alice Japan identified for Kojima Minami was directly encoded in her titles. Cosplay scenarios, school settings, projects emphasizing freshness. Between ages 18 and 21, her positioning as “the icon of innocence” solidified.

While she appeared in a 2012 magic mirror booth project and 2013 dirty talk series, her core remained consistently “cute girl.” Her sweet anime voice, dialogue delivered with affectation, and petite frame suited to uniforms and school swimsuits—this “prototype” would gradually transform during her S1 era.

S1 Number One Style Era (2014–2024)—A Decade of Evolution

The Impact of Transferring to S1

In March 2014, Kojima Minami moved as an exclusive performer to S1 (S1 Number One Style). Her debut work with the label: “Exclusive No. 1 Style Kojima Minami’s Squirting Full Course.” From Alice Japan’s innocent-girl trajectory to a major label’s flagship performer. Age 21.

S1 was a mega-label boasting top actresses like 三上悠亜 (Mikami Yua), 奥田咲 (Okuda Saki), and 葵つかさ (Aoi Tsukasa). Production budgets, video quality, promotional scale—everything moved up a tier. The scale of Kojima Minami’s productions transformed. From “cute girl AV,” production shifted toward works with stronger dramatic elements and scenario design.

Early Period (2014–2019): Continuing the Beautiful Girl Era

Immediately after the S1 transfer, works largely inherited the beautiful girl trajectory from Alice Japan. Cohabitation scenarios, female student settings, lingerie model premises. However, S1’s distinctive high-definition quality and lighting gave even “beautiful girl” content an entirely different texture. Skin texture, shadow in facial expressions, perspiration quality. As video technology advanced, her acting required greater sophistication.

In September 2018, she tackled harder elements including squirting and bondage in an assault-themed work. February 2019 saw a “Double Minami” collaboration with 初川みなみ (Hatsukawa Minami), earning 30 reviews averaging 4.10 points—one of the highlights of her early S1 period. Parallel releases with Alice Japan continued through this period, with weeks sometimes seeing simultaneous releases from both labels.

Later Period (2020–2024): Emergence as Woman

The turning point came around 2020. Her focus shifted toward adult scenarios: married woman settings, forbidden relationships with stepfathers, NTR. The December 2020 film featuring a wife seduced by her stepfather’s technique gathered 37 reviews averaging 4.41 points. The emergence of films receiving over 30 reviews signaled the growing depth of her fanbase.

November 2021 saw a work on edging and denial themes achieve an average of 4.81 points across 21 reviews. April 2022 brought another 4.48 average (23 reviews) on infidelity themes. From 2023 onward, she consistently maintained averages above 4.5 points while expanding genre range monthly—power harassment boss, insatiable wife, NTR group scenarios.

A 10-Year Milestone

July 2021 marked her 10-year debut anniversary. S1 released a 16-hour best collection featuring all 69 of her works with the label. Review average: 4.81 points across 31 reviews. 69 works in 10 years—that was her S1 output alone. According to Tokyo Sports reporting, there were moments of tears during interviews. The weight of shouldering the same label’s banner for a decade was evident.

The position Kojima Minami built over this decade was singular. S1 had actresses with overwhelming recognition like 三上悠亜 (Mikami Yua) and technical specialists like 河北彩花 (Kawakita Saika). Kojima Minami fit neither category, carving her niche through “longevity, consistency, and breadth.” She wasn’t a dominating specialist in one genre. Versatile enough to deliver 70+ points in any scenario she was placed in—that consistency explains 10 years without interruption in releases.

Madonna Era (December 2024–Present)—What Changed in New Territory

A Decision in the 13th Year

October 2024 saw her final S1 release. Reviews were mixed, averaging 2.93 points across 40 entries. The sheer volume of 40 reviews itself testified to her continued recognition at S1.

Then on December 20 of that year, “Shocking Transfer: Kojima Minami’s Madonna Debut—From Legend Beautiful Girl to Legend Beautiful Woman” arrived. Madonna specializes in married women and mature actress genres. At 32, Kojima Minami’s choice of Madonna as her new home made logical sense. Her track record of high ratings in married woman and NTR content at S1 naturally aligned with Madonna’s world.

The Turning Point: First Creampie

January 2025 saw Madonna release number two feature her first creampie scene. “After 13 Years, Finally,” read the title’s subtitle, speaking to career significance. The film gathered 36 reviews averaging 4.42 points. To debut a taboo genre in a new label’s second release demonstrated bold commitment to the Madonna transition.

Post-January 2025 maintained monthly releases. NTR, married woman, brother-in-law scenarios—she attacked Madonna’s specialty situations successively. April 2025 brought a camping NTR film; May 2025 saw an infidelity-themed NTR release. June 2025’s brother-in-law work achieved her highest Madonna rating yet: 4.82 points across 17 reviews.

590 Works Reflect the Evolution of Performance

Tracking Kojima Minami’s filmography chronologically reveals three distinct phases.

Phase One: Alice Japan’s “Reaction Era.” Her smile toward camera, sweet voice, surprised expressions. Passive reaction performance was her weapon. She responded to male actors’ movements, adjusted scene temperature through vocal tone. The “cute girl” appearing on screen was the product itself.

Phase Two: S1 Mid-Period Forward, the “Power Dynamic Reversal.” Dominant scenarios, fellatio-lead works, controlling office boss roles. Her style shifted toward actively seizing the camera. In 2023’s edging technique films, screen control rested entirely with Kojima Minami. She read opponent reactions, controlled pacing, drew responses from her male counterpart. Her 150 cm frame commanded authority on screen—the image carried inexplicable persuasion.

Phase Three: Post-Madonna “Switching.” Receiving acceptance as a married woman, acting with agency toward infidelity. Both her early passivity and later assertiveness, now deployable scene-by-scene. The breadth of technique accumulated over 15 years aligned perfectly with Madonna’s complex scenarios. Not a straight line of “beautiful girl becoming woman,” but rather an expanding swing—the result is ever-expanding role possibilities.

Another observation across her career: voice transformation. Her initially sweet anime voice shifted by late S1 to incorporate lower registers. Breathy whispers, voice catching when emotion surged. Her vocal range expanded, allowing recognition without seeing screen—she acquired a distinctive “sound.” That voice combination from a 150 cm frame became her greatest differentiator.

Another Side—Music, Brand, and Screen

Ototoi Friday—8 Years of Musical Pursuit

In 2016, Kojima Minami formed a music unit “Otome Frappuccino” with ally 紗倉まな (Sakura Mana). Following a name change to “Ototoi Friday” in March 2017, they adopted “slightly avant-garde” as their concept. They received track submissions from indie scene talents like Satoko Shibata and Ain of NATSUMEN.

This wasn’t AV actresses dabbling in music. Music Natalie covered them repeatedly; CINRA.NET ran substantial interview features. They held paid live performances and produced MVs under EMC production. In a 2016 CINRA interview, both stated “we want to affirm the AV industry.” Activity paused during COVID but restarted in 2023. February 14, 2024 saw the album “OTOTOY FRIDAY” release—a collection spanning roughly 8 years.

LOU LOU—Dog Harness Brand

November 2024, Kojima Minami launched “LOU LOU,” a specialized brand for one-piece dog harnesses. Pursuing designs that reduce neck strain, she involved herself from material selection through design. Prioritizing Japanese manufacturing and functionality from a dog-lover’s perspective.

2025 saw appearances at dog festivals with cooling-tech summer harnesses receiving positive response. April 2026 marked her second consecutive appearance at InterPet Tokyo. She expanded sizing from toy breeds to small breeds and signaled ambitions for B2B expansion. When interviewed by Tokyo Sports, she commented “I’m happy to hear customer voices,” revealing her commitment to in-person sales at events. This wasn’t celebrity name licensing but authentic personal passion growing a business. Authenticity builds repeat customers.

Terrestrial TV Commercials and Screen

From October 2025, she appeared in Sharp’s EV concept model “LDK+” commercials; January 2026 brought Optage’s “eo” commercial. This isn’t “the era of AV actresses in commercials”—rather, Kojima Minami’s terrestrial television exposure as a variety talent preceded any commercial appearance.

Film appearances trace back to 2014’s “God Tongue Kiss Endurance Championship: The Movie 2 Psychic Love.” She had regular variety show appearances on “God Tongue” and activity history with idol units like Ebisu Muscats and SEXY-J. Her cross-industry career expanded gradually over 15 years through incremental ground-building rather than sudden jumps.

In a 2025 Josei SPA! interview, she discussed revealing her true profession to family. She neither hid her AV career nor avoided confronting industry prejudice. “We want to affirm the AV industry”—the sentiment expressed in a 2016 CINRA interview with 紗倉まな (Sakura Mana) persists through her entire 2026 activity.

Representative Works Tracing Career Turning Points

From Kojima Minami’s 589 works, five films mark critical junctures, arranged chronologically.

True S1 Mastery—Edging and Climax Architecture (November 2021)

Her eighth year with S1. A work where denial and edging accumulate to extremes, constructing the climax that follows like architectural blueprint. Her body control commands the entire film. Review average 4.81 points across 21 reviews. Despite the “extreme sex” label, the content crystallizes precision-engineered performance. This symbolizes her S1 mid-to-late transition from “one being acted upon” to “one commanding screen presence.”

S1’s Peak Achievement—Power Harassment Boss × High-End Escort (March 2023)

Review average 4.89 points (18 reviews) represents her highest solo-work rating. By day, a boss tormenting subordinates; by night, a premium escort. Her dual-persona role involves power dynamics that reverse multiple times within a single film. Facial switching, vocal modulation, the coldness of her daytime gaze versus her night-time melting. Every technique accumulated across 12 years emerges within one role. A work worthy of being called S1’s culmination.

Final S1 Work—Power Reversal with Childhood Friend (June 2024)

Released during her final S1 period. A daycare worker whose childhood friend—previously dismissible—reverses positions of power. Review average 4.78 points across 9 reviews. While the premise is familiar, the age-matured Kojima Minami delivers convincing collapse of “older woman composure.” The visual fit of her 150 cm frame as a daycare worker compounds successful casting.

Madonna Debut—From Legend Beautiful Girl to Legend Beautiful Woman (December 2024)

The subtitle says everything. Shedding 13 years of “beautiful girl,” declaring her entrance as “beautiful woman” into new territory. Within Madonna’s signature subdued lighting and restrained cinematography distinct from S1, Kojima Minami’s expressions took on new hues. The same person, the same actions, yet label change alone alters perceptual texture entirely. A work embodying what label transfer means.

Blooming at Madonna—Forbidden Chemistry with Brother-in-Law (June 2025)

Her highest-rated Madonna work. Review average 4.82 points (17 reviews). Beginning with “sympathizing with my 30-year-old virgin brother-in-law,” the film carefully depicts emotion wavering between maternal instinct and transgression. A theme absent from S1: “transgression beginning from kindness.” The new Madonna environment unlocked previously unexplored dimensions of her performance. The transfer was correct—one film confirming it.
