S1 GIRLS COLLECTION Complete Guide | 1,000+ Best-Of Compilations

Over 1,000 Titles—A Series Names Itself in Its Own Works

On March 27, 2026, S1 NO.1 STYLE released a compilation. Its title: “The Most Beautiful AV Actresses in Japan: 100 SEX—S1 GIRLS COLLECTION 1,000-Title Memorial Release.” 462 minutes of content, over 10,000 favorites. The series reached its 1,000-title milestone—and commemorated it by inscribing the series name into the work’s title itself.

Thanks to your continued support, S1 GIRLS COLLECTION—our popular series featuring beautiful stars representative of the adult entertainment industry—has surpassed the milestone of 1,000 titles. (FANZA product description, as of June 2026)

S1 NO.1 STYLE’s main catalog exceeds 6,800 titles. From this library, S1 GIRLS COLLECTION extracts the layer of “best-of, complete-box, and memorial” releases—1,072 titles as of June 2026. Over 20 years old, the label has spent two decades consolidating actress careers through this release apparatus, continuing to publish multiple new titles monthly.

This article dissects those 1,072 titles across five subcategories, seven representative works with official FANZA descriptions, and three editorial principles. Data was gathered from FANZA on June 3, 2026.

The Series Structure—S1’s Umbrella Brand in Five Subcategories

S1 GIRLS COLLECTION is not a single numbered series. It is a large-scale category consolidating “best-of, complete-box, compilation, and memorial releases” within S1 NO.1 STYLE. Release numbers follow the uniform ofje prefix and are managed separately from current single releases.

Works in the series fall into five subcategories.

Individual Actress Complete Box

This category gathers an actress’s entire filmography into one box at retirement or graduation. Yua Mikami’s complete 96-title 48-hour box, Ai Hongo’s complete 19-title 15-hour box, Mirei Uno’s complete 29-title 16-hour box, and Shion Yumi’s complete 38-title 16-hour box. Each offers viewers the ability to purchase an entire actress’s career in a single release.

Thematic Best-Of 100+ Series

Compilations crossing multiple actresses by body type or play style. Best 100 Actresses 16-hour, Fellatio 48 Actresses 8-hour, Cowgirl Position 100, Creampie Extremes 203 consecutive scenes 6-hour. Multiple actresses in one release serve as an entry point for new fans.

Memorial Releases

These mark milestones for the series itself or S1’s history. The 1,000-title memorial, S1’s 20th-anniversary release, and 5th/10th-anniversary best-ofs for individual actresses. These are fewer in number but symbolically represent the series’s direction.

User-Vote Releases

A new category launched in May 2026. The S1 General Election 2026 declares itself “history’s first adult video composed by user votes,” selecting 50 scenes through fan voting via the official S1 X account.

Individual Actress Anniversary Best-Of & Debut Best-Of

For active (non-retiring) actresses: “N-anniversary” and “debut best-of” releases. Mei Washio (J-cup 12-hour), Saika Kawakita (6-year career 24-hour), Fua Kaede (3-year career 33 titles), Ren Gojo (debut 1st anniversary), Niko Kawagoe (1-year compilation 12 titles).

The parallel operation of five subcategories enables the series to handle both “current output” and “archival consolidation” within the same framework.

Series Foundation Data

Series Name: S1 GIRLS COLLECTION

Maker & Label: S1 NO.1 STYLE

Total Titles: 1,072 (as of June 2026)

Status: Ongoing (multiple releases per month)

Related Series: S1 PRECIOUS GIRLS (active collaborations) / S1 VR (VR division)

FANZA’s official series description reads: “A popular series featuring beautiful stars representative of the adult entertainment industry as a whole.”

S1 NO.1 STYLE was founded in 2004 with a main catalog exceeding 6,800 titles. S1 GIRLS COLLECTION sits as a “best-of layer” above this—roughly one in seven titles from the main catalog feeds into this framework.

1,072 Titles Over 12 Years—Three Eras of the Series

Era 1: 2014–2022 Individual Actress Anniversary Best-Ofs as Foundation

Series ID 5087 is estimated to have been assigned around 2014. The earliest confirmed release, “Yua Mikami 2-Year Memorial Best: 12 Titles, 480 Minutes,” appeared as a best-of for a rising young actress. At this stage, “individual actress N-anniversary best-of” formed the series’s core format.

Era 2: 2023–2024 Thematic Best-Ofs and Retirement Boxes Established

September 2023’s “Mei Washio’s Mega J-Cup 12-Hour Special” exemplifies the body-feature-focused compilation. With 725 minutes and 16,566 favorites, its structure—organized into 62 segments around the J-cup aesthetic—became the prototype for later thematic 100-actress compilations.

June 2024’s Yua Mikami retirement 48-hour box became the series’s biggest hit. With 42,213 favorites, it stands unrivaled within the series. The retirement complete-box format solidified as a definitive edition.

That same year saw Shion Yumi’s graduation special 16-hour release, establishing the “graduation” format as well.

Era 3: 2025–2026 20th Anniversary, 1,000-Title Mark, User Voting

S1 NO.1 STYLE’s founding (November 2024) marked the 20th anniversary. Afterward, the series expanded into “thematic best-of 100 actresses” and “all-actress crossover” releases. From May 2025’s “Masterpiece Super-Body Collection: Best 100 Actresses 16 Hours” through May’s Mirei Uno retirement compilation and December’s Ai Hongo retirement box to March 2026’s “Active-Era Top 100 SEX 12 Hours,” new releases continued at 1–2 per-month pace.

Following the March 27, 2026 1,000-title memorial and May 22’s S1 General Election 2026, the series began incorporating user-community participation.

Seven Works Across All Territory of S1 GIRLS COLLECTION

Seven representative works by subcategory, with official FANZA descriptions quoted directly.

1. The 1,000-Title Memorial Release—The Series’s Own Milestone

Released March 27, 2026. “The Most Beautiful AV Actresses in Japan: 100 SEX” commemorates the series’s 1,000-title milestone. 462 minutes, over 10,000 favorites.

The product description is a lengthy self-definition from the series itself:

Why S1 is the supreme single-label maker. Because of overwhelming visual beauty.

You could say we have Japan’s most beautiful actresses. If there were a world championship, S1 actresses would represent Japan.

They have always been beautiful. Right now might be their peak. Always, consistently beautiful.

Beautiful stars representative of the adult entertainment industry as a whole gathered in the popular series

S1 GIRLS COLLECTION

Thanks to your continued support, we have surpassed 1,000 titles. (FANZA product description, as of June 2026)

“Popular series S1 GIRLS COLLECTION” and “surpassed 1,000 titles.” The structure of the series inscribing its own name into the work’s title expresses the intent to preserve label history as an archival device.

2. S1’s 20th-Anniversary Best 100—Largest Thematic Compilation

Released May 23, 2025: “Masterpiece Super-Body Collection: Best 100 Actresses 16 Hours #S1 20th Anniversary #AV History’s Strongest Cast #Beautiful Large Breasts #Beautiful Curves #Beautiful Buttocks #Rare Female Bodies in Top 2% of Japan.” 961 minutes, approximately 16 hours.

The five hashtags opening the title are S1’s signature format—converting product metadata directly into promotional copy. The tagline “#Rare Female Bodies in Top 2% of Japan” epitomizes the extreme numerical appeal of thematic 100-actress compilations.

The description opens with a passage on the reason for existence of long-form compilations:

Masturbation should be free. Whenever, wherever, for whoever. But tastes vary infinitely. With 100 women comes 100 different faces, eroticism, and desirable bodies. Hence, one hesitates.

This is 16 hours of 100 erotic bodies offered in service of your free masturbation. From super bodies worthy of AV history to girl-next-door bodies that would excite anyone nearby—all 100 were born for your pleasure. (FANZA product description, as of June 2026)

“Super bodies worthy of AV history” and “born for your pleasure.” At the 20-year milestone, S1 explicitly redefines its catalog’s reason for existence.

3. Yua Mikami’s Final AV—The Series’s Biggest Hit 48-Hour Box

Released June 7, 2024: “Yua Mikami: Final AV—Complete History 96 Titles, Complete 48-Hour Box.” 2,879 minutes, 42,213 favorites, 40 reviews. This records the series’s highest favorite count.

Yua Mikami’s birth: June 1, 2015. With cooperation from MUTEKI, MOODYZ, and IDEA POCKET—transcending maker boundaries—her entire 96-title career from debut through retirement is presented without reservation, a genuinely final AV work. Beautiful and erotic in every frame, pioneering an unprecedented path as both an AV actress and influencer, commanding overwhelming popularity across genders—her 8-year history is tightly packed into this 48-hour box. Brimming with masterpieces from the legendary AV actress whose legacy will pass to posterity, burn through it all with unrelenting pleasure. (FANZA product description, as of June 2026)

Noteworthy is the phrase “with cooperation from MUTEKI, MOODYZ, and IDEA POCKET.” This is not solely an S1 production; competitors collaborated to provide rights, enabling all 96 titles to be edited into 48 hours. This exceptional arrangement required cross-industry business judgment. Yua Mikami’s name transcended S1’s frame to be treated as an industry-wide legend.

The 48-hour duration equals approximately two days of continuous viewing. The physical presence of a box product combined with digital preservation completeness—a definitive-edition positioning.

4. Ai Hongo’s Retirement Complete—2.5 Years, 19 Titles of Concentrated Career

Released December 26, 2025: “Ai Hongo Retirement: S1 Complete 19 Titles, 15-Hour Box.” 929 minutes, 13,249 favorites.

In 2023, Ai Hongo began a new chapter as an S1 actress.

With each film, her beauty and eroticism refined further.

A lovely face happily sucking and licking the penis. A beautiful arching waist writhing at climax. Ideally rounded hips brutally slamming in cowgirl position, self-driving with obscene abandon. Her body entwined around him, drenched in their combined fluids.

No matter the act, with Ai Hongo, every scene becomes erotic.

Refined, beautiful, overflowing—yet vulgar and obscene.

This is Ai Hongo’s totality.

The Ai Hongo legend concludes here. (FANZA product description, as of June 2026)

From 2023 S1 debut through 2025 retirement—2.5 years, 19 titles. Contrasting with Yua Mikami’s 8 years and 96 titles, this actress left a condensed, high-density career. The phrase “the Ai Hongo legend concludes here” sets the standard copy for S1 retirement compilations.

Retirement boxes continue at a 1–2 per-year pace: Yua Mikami (2024), Mirei Uno and Ai Hongo (2025). For major S1 contract actresses, the retirement complete-box functions as the official career closure.

5. Mirei Uno’s Retirement 16-Hour—The Definitive G-Cup Idol

Released May 23, 2025: “Mirei Uno Complete History: All 29 Titles Final Retirement AV Complete 16-Hour.” 961 minutes, 13,364 favorites, 10 reviews.

With idol-like visuals and miraculous G-cup divine breasts—AV history’s rare beautiful girl Mirei Uno in all 29 titles. Drama, climax play, documentary—with each film, her innate eroticism awakens. Sixteen hours capturing her growth from an innocent girl to an erotic-blooming AV actress.

Transparent, innocent smile, genuinely kind personality—thank you, truly thank you, truly thank you for becoming an AV actress. Mirei Uno’s genuinely final best-of. (FANZA product description, as of June 2026)

29 titles compressed into 16 hours. Approximately 33 minutes per title. S1’s retirement complete-boxes emphasize not “showing all works” but “extracting highlights from all works.”

The direct gratitude—“thank you for becoming an AV actress”—characterizes S1’s actress-promotion tone. Closing a retirement description with maker gratitude toward the actress is rare industry-wide.

6. Active Era’s Top 100 SEX—The Counterconcept to Retirement Complete-Boxes

Released March 20, 2026: “S1 Complete 100 SEX: All of the Active Top AV Actresses 12 Hours.” 716 minutes, 8,890 favorites.

S1’s Golden Age Continues! Active Top AV Actresses Assemble! From nervous debuts to works that topped FANZA rankings repeatedly, from strongest-duo scenarios creating cute-and-erotic chemistry to countless-fan favorite-series masterpieces—a gratitude-filled 100-scene 12-hour festival for users who love AV.

This one disc alone sustains your masturbation for a year This one disc alone covers all actresses completely This one disc alone elevates your pleasure-level further Quality ✓ Quantity ✓ (FANZA product description, as of June 2026)

If retirement complete-boxes consolidate individual actress careers, “Active Era’s Top 100 SEX” consolidates S1’s present status into one release. Its release—one week before the 1,000-title memorial (March 27)—positions it as “current output” ahead of the series’s own milestone.

The hyperbolic tagline—“sustain your masturbation for a year from this one disc”—embodies the confidence of a compilation.

7. S1 General Election 2026—First User-Voted Composition

Released May 22, 2026: “S1 General Election 2026: Selected by User SNS Votes—‘Most Effective AV Scenarios’ 50-Scene Selection With Recommendations Known Only to Core Users” 481 minutes, 1,327 favorites.

Historic First: An adult video composed entirely by user votes is born!

Through S1’s official SNS, we collected votes globally for “the most effective AV scenario.”

Among the mountains of AVs out there, which scenario most ignited viewers worldwide?

We’ve extracted scenario highlights and included recommendations from users themselves!

Only core AV fans would know such “extra-pleasure” details!

Once again, thank you to everyone for responding. Your answers and comments provided us at the S1 production department with great interest. We look forward to hosting a second election! (FANZA product description, as of June 2026)

“Historic first: an adult video composed by user votes.” Through the S1 official X account (@S1_No1_Style), fan votes selected the “most effective AV scenario.” As a new release, favorites lag behind other titles.

The phrase “we look forward to hosting a second election” signals this as an upcoming recurring format. A fan-participatory compilation—a rare industry experiment.

Editorial Philosophy—Three-Digit Numerics, Completeness, Anniversaries

Across the seven descriptions, S1 GIRLS COLLECTION’s shared editorial grammar emerges: five recurring formats—“all ○ titles,” ”○○-hour box,” “100 scenes,” “final AV,” and ”○○ anniversary.”

Numerical Emphasis in Three Digits

“100 scenes,” “100 SEX,” “100 actresses,” “100 of,” “48 hours,” “16 hours,” “12 hours,” “all 96 titles,” “all 29 titles,” “203 consecutive,” “177.” Three-digit numerals always appear in titles and descriptions. Viewers calculate purchase decisions by “hours included” or “titles included.” The series designs products around this measurement standard.

Completeness Emphasis

“All ○ titles,” “complete compilation,” “complete preservation edition,” “genuinely final.” Retirement boxes especially stress the limited-time opportunity—“another chance to collect this actress won’t come.” The Yua Mikami box’s “including her career transcending maker boundaries” represents the extreme.

Anniversary Leverage

S1’s 20th anniversary, 1,000-title milestone, debut 1st anniversary, 3-year career, 6-year career, debut-to-retirement 8-year career. Milestones serve as external triggers for best-of releases. Inscribing the series’s own milestone (1,000 titles) into the work’s title reflects S1’s self-referential stance.

Encoding Hierarchy in Recording Time Per Title

48-hour box (Yua Mikami) → 24 hours (Saika Kawakita 6-year) → 16 hours (thematic best-of 100, Mirei Uno, Shion Yumi) → 15 hours (Ai Hongo) → 12 hours (active top, J-cup best, fellatio 48, multiple anniversaries) → 8 hours (theme-focused). The hierarchy is clear; product category maps to recording time.

The Series’s Biggest Hit—Yua Mikami’s 48-Hour Box Reconsidered

Among the seven, Yua Mikami’s 48-hour box (42,213 favorites) stands out starkly. Compared to other retirement boxes in the series (Ai Hongo: 13,249; Mirei Uno: 13,364), it commands over 3x the support.

Three factors explain the difference, drawn from descriptions and public data.

First: volume of appearances. Yua Mikami’s 96 titles dwarf Ai Hongo’s 19 and Mirei Uno’s 29—three to five times greater. Information density directly translates into viewing time (48 hours vs. 15–16 hours).

Second: cross-maker compilation design. As the description states, “with cooperation from MUTEKI, MOODYZ, and IDEA POCKET”—this isn’t solely S1. Industry leaders cooperated to compile her work. During her career, Yua transitioned from her pre-S1 MUTEKI era through MOODYZ and IDEA POCKET; at retirement, one company (S1) consolidated it all. This business decision hinged on Yua’s marquee value—difficult to replicate for other actresses.

Third: cross-sector influencer status. The phrase “pioneering an unprecedented path as both an AV actress and influencer, commanding overwhelming popularity across genders” indicates her fan base transcended adult-video viewers. The high favorite count reflects not just AV merit but also her monumentality as a celebrity.

Related Series—Role Division of S1 PRECIOUS GIRLS and S1 VR

Around S1 GIRLS COLLECTION, parallel series operate.

S1 PRECIOUS GIRLS

A “current-actress collaboration” series featuring S1 contract actresses. While GIRLS COLLECTION addresses “past-catalog best-of and complete-boxes,” PRECIOUS GIRLS handles “active actresses in new collaborations.”

Industry records indicate S1’s 20th-anniversary push began November 2024 with seven consecutive monthly releases. The first, “S1 PRECIOUS GIRLS 2024,” featured 24 contract actresses—pairing with GIRLS COLLECTION’s 20th-anniversary 100-actress best.

S1 VR

The VR division series. It operates on a separate axis from GIRLS COLLECTION with distinct release numbers, consolidating S1 NO.1 STYLE’s VR catalog.

GIRLS COLLECTION (past-catalog compilations), PRECIOUS GIRLS (active-actress collaborations), and S1 VR (VR division) form the three strategic pillars of S1 NO.1 STYLE’s brand, operating in parallel.

Position Within Industry Big 4 Best-Of Strategy

S1 GIRLS COLLECTION’s 1,000+ titles represent the largest scale in the AV industry. Comparison to the Big 4 competitors’ strategies clarifies its position.

S1 NO.1 STYLE’s S1 GIRLS COLLECTION (1,072 titles) operates across diversified formats: retirement complete-boxes, anniversary compilations, thematic best-of 100s, and user-voting releases. This breadth of subcategories is industry-leading.

MOODYZ’s MOODYZ BEST centers on retirement-memorial boxes; the series is smaller than S1’s.

SOD Create’s SOD Create The Best uses individual actress “The Best” numbering (e.g., Mana Sakura Vol. 14) with monthly releases.

IDEA POCKET’s IDEA POCKET The Best follows a similar sequential structure; the overall scale lags behind S1.

S1 GIRLS COLLECTION’s hallmark is “format diversification.” Retirement boxes, thematic 100-actress compilations, anniversaries, user voting, and active-actress crossovers—the most subcategories in the industry. Unlike SOD Create’s sequential “The Best Vol. 14” method, this is an umbrella-brand operational model.

The extreme 48-hour duration (Yua Mikami box) also appears rarely in competitors’ compilations. Its viability depends on physical-disk box products being commercially sustainable.

Viewer Profiles Well-Matched to the Series

The five subcategories and seven representative works sketch the audience for S1 GIRLS COLLECTION.

Want to experience all S1 actresses. For viewers seeking multiple active actresses in one title, “Active Era’s Top 100 SEX” (12 hours) or “20th-Anniversary Best 100” (16 hours) serve as entry points. Condensed editing of a few minutes per film gives an overview of S1’s entire catalog.

Want to consolidate a favorite actress’s career. Retirement/graduation milestone complete-boxes gather all an actress’s work into a definitive edition. Yua Mikami’s, Ai Hongo’s, Mirei Uno’s, and Shion Yumi’s retirement boxes, plus Saika Kawakita’s 6-year 24-hour compilation, are prime examples.

Want to narrow by body type or scenario. J-cup best, fellatio 48, cowgirl 100, creampie 203, and spread-pussy 100—targeted thematic compilations are available.

Want to share S1’s history and milestones. The 1,000-title memorial, 20th-anniversary, and N-anniversary releases commemorate the series or label’s journey. This resonates with audiences who feel invested in S1 as fans.

Want to try experimental new formats. The S1 General Election 2026’s user-voting format is rare industry-wide. With a second election announced, the participation experience itself is enjoyable.

Conversely, poor fit: viewers seeking long-form dramatic single titles. GIRLS COLLECTION is compilation; per-title recording is brief. For narrative depth, S1 NO.1 STYLE single releases are more appropriate.

Conclusion—1,072 Titles Remembering S1’s 20 Years

S1 GIRLS COLLECTION is an umbrella brand drawing 1,072 titles from S1 NO.1 STYLE’s 6,800+ catalog—extracting “best-of, complete-box, and memorial” releases. Five subcategories (individual actress complete-boxes, thematic best-of 100, memorial releases, user-vote projects, individual actress anniversaries) operate in parallel, with monthly multi-title releases continuing.

The series’s biggest hit is Yua Mikami’s 48-hour retirement box (42,213 favorites). Its exceptional cross-maker arrangement consolidating 96 titles into one label reflects business judgment driven by her star power. Ai Hongo’s, Mirei Uno’s, and Shion Yumi’s retirement boxes each exceed 10,000 favorites.

Multiple entry points exist. For series milestones: the 1,000-title memorial. For thematic best: the 20th-anniversary 100-actress 16-hour. For retiring legends: Yua Mikami’s 48-hour. For active-actress crossover: the active-era top 100-SEX 12-hour. For novel formats: S1 General Election 2026. The 12–48 hour recording hierarchy allows selection by viewing environment and mood.

For broader S1 NO.1 STYLE context, see S1 NO.1 STYLE Complete Guide. For active S1 contract actresses, individual articles cover Riri Nanatsumori, Niko Kawagoe, and Saika Kawakita. If an actress from GIRLS COLLECTION catches your interest, exploring individual pieces creates a natural pathway.

Fragmented viewing on free sites differs from the 1,072-title structured compilation. Yua Mikami’s 48-hour box carries 48 hours of editorial judgment; Mirei Uno’s 16-hour condenses 29 titles’ worth of decisions; the 20th-anniversary best-of carries 100-actress selection logic. If a title intrigues you, purchase it on FANZA to experience S1’s 20-year legacy.
