Miho Nana | The Guitar Girl Who Became S1's Brightest Star

A 19-Year-Old Put Down Her Guitar and Knocked on S1’s Door

Before we talk about Miho Nana (未歩なな), let me ask you something.

Does the name “Momose Konan” (百瀬こなん) ring a bell? She was the guitarist and vocalist for a girls’ band called “WAI WAI PLANET.” She played guitar on live house stages, sang her heart out, and worked up a sweat in small venues.

In June 2022, that girl made her AV debut with S1. She was 19 years old.

Her debut work scored a 4.42 rating with 134 reviews. For a debut in S1’s prestigious NO.1 STYLE newcomer series, those are seriously impressive numbers — and the industry took notice. “Why would a girl who plays guitar go into AV?” some asked. Here’s what she said:

“There are so many cool, shining people in this industry, and I thought I wanted to try it too. I’ll do my best to stand out in both sexiness and cuteness!”

Did she stand out? To cut to the chase — absolutely. Over 3.5 years, she put out roughly 39 solo works, 7 VR titles, and appeared in 173 releases total. She retired in December 2025. She was S1 through and through — not a single title with another studio. A true, pure-blooded S1 actress.

Miho Nana — “Naatan” by the Numbers

Standing 156cm tall. Measurements: B86 / W56 / H85, D-cup. Born August 12, 2002, from Kanagawa Prefecture. Her nickname is “Naatan” (なぁたん).

Looking at the numbers alone, she’s honestly not the most eye-popping spec sheet. S1 has taller girls and bustier girls. But Miho Nana’s weapon was never about that.

Her greatest weapons were her smile and her gap appeal.

Look at her work titles: “Super Energetic and Super Cute,” “Beloved Solar System Beauty,” “Genuinely Nice Girl,” “With a Beaming Smile.” The adjectives that S1’s production team kept putting in her titles were all about her personality. Normally, a studio at S1’s level leads with looks or body features. With Miho Nana, her good nature was the selling point.

That’s genuinely unusual in this industry.

Her official social media includes X (@miho_nanachan) and Instagram (@miho_nanachan, 170K+ followers). She also ran a fan club called “Naatan Chi no Wa” and actively hosted events — imoni hot pot gatherings in Sendai, Halloween cheki photo sessions, you name it. That closeness to her fans was a defining trait.

She released multiple photobooks. Her first, “Nana no Ichi.” came out in September 2022 through Tokuma Shoten, just months after her debut. She followed up with “etoile” on FANZA (September 2023), “Clarity” (July 2024), the “Best naked” series (November 2024 through December 2025, four volumes), and a Shukan Post digital photobook. You can see a clear awareness about being seen — beyond what her AV work offered.

From the Band Stage to the AV Studio — A Guitarist’s Transformation

Here’s the part you can’t skip when talking about Miho Nana.

Before AV, she was “Momose Konan,” a member of the girls’ band WAI WAI PLANET, handling guitar and vocals. Her activities were centered on live house performances, and she’d uploaded guitar cover videos on YouTube. Her cover of “Kaze ni Naru” had even gotten some buzz.

In other words, she was already someone with zero resistance to expressing herself in front of an audience. There’s no question this pre-AV career had a massive impact on her work.

The day after her AV debut, on June 29, 2022, she held a live performance at Ikebukuro Live inn ROSA. A live show the day after her AV debut. It was already clear at this point that this girl had no intention of walking the typical AV actress career path.

In July 2022, she appeared in Weekly FLASH, landing a coveted sealed gatefold feature right away. Shot by Saijo Akihito. Her translucent 19-year-old nudes became a talking point. By September, she had a photobook out through Tokuma Shoten. An S1 actress achieving this level of media exposure within three months of debut is remarkably rare even in recent years.

Then in September 2023, she released a solo single called “Koakuma Darling,” distributed on all major streaming platforms — Apple Music, Spotify, LINE MUSIC. AV actresses releasing solo music isn’t unprecedented, but Miho Nana’s case was different: music led to AV, and AV led back to music. This cycle, I believe, is the core of her career.

”Mi LUNA” — The Day an AV Actress Became an Idol

Let’s dig a bit deeper into the music side.

An idol unit called “Mi LUNA from Otsuki-chan no Uta” was born from a TV Tokyo show called “Tsuki to Mogura.” Miho Nana was a founding member, starting as a three-person lineup with fellow S1 actresses Yagi Nana (八木奈々) and Furukawa Honoka (古川ほのか), later adding Ishihara Nozomi (石原希望) and Aoi Ibuki (葵いぶき).

The B-side of their 1st single “LUNA LOOP” (January 2024), titled “Koi no MotoGP,” was written by comedian Tom Brown’s Michio. Their 2nd single “Kimi no Hitomi ni” showcased the revamped lineup’s performance.

In an interview, Miho Nana said:

“I hope we can cover each other’s weaknesses and turn our close bond into a strength.”

“Being around everyone makes me think, ‘I need to get better too.’”

Shooting solo AV works while practicing dance routines with an idol unit, performing live for fans, and appearing on variety shows. This incredible multitasking ability was built on the foundation she developed as a “performer” during her band days.

For fans who know her main career as a sexy actress, seeing her on stage as an idol is a completely fresh experience. Actresses who offer that kind of multi-layered enjoyment are genuinely rare in this industry.

Retirement — “The Most Fun I’ve Ever Had in My Life”

On July 29, 2025, Miho Nana announced her retirement on social media.

“I, Miho Nana, will be retiring as an AV actress at the end of December 2025. These roughly three years since my debut — the time I spent with all of you was truly a treasure, and being Miho Nana was the most fun I’ve ever had in my life.”

“Until my retirement, I want to give back to everyone and create even more meaningful time together. I’ll run at full speed until my very last moment as Miho Nana.”

Retiring at 23. That’s young. But looking back, the density from her debut onward was extraordinary. Releasing solo works at a pace of one per month while juggling music, variety show appearances, photobooks, and fan events. She packed roughly five years’ worth of a typical actress’s workload into 3.5 years.

Her final release was “Real Fan Appreciation Festival” (snos00033) — a concept where fans compete directly against her, and if they win, they get to have sex. Right to the very end, she stayed true to her commitment to fan engagement. A very Miho Nana way to go out. Review score: 4.08.

In April 2026, “Complete Retirement: Last AV — All 39 Works Complete 16 Hours” (ofje00624) is scheduled for release. A definitive box set containing every solo work — the last “new release” to ever hit the market under her name.

Natural-Born Presence — Not So Much Acting Ability as Sheer Existence

Now let’s talk about the work itself.

After watching more than 30 of Miho Nana’s titles, what I felt was that she’s not exactly “a good actress” in the traditional sense. More precisely, she’s the type where her natural self translates directly into compelling AV.

Her smile is genuine. Her reactions are real. When she’s happy, she looks truly happy. When she’s flustered, she looks truly flustered. Rather than performing a constructed character in front of the camera, Miho Nana the person is simply there on screen.

This comes through especially strongly in her VR work. Her VR debut, “VR NO.1 STYLE Miho Nana Unlocked” (sivr00248), pulled in a staggering 221 reviews averaging 4.19 — top-tier numbers even among S1’s VR catalog. In VR, an intimate medium, her unfiltered “self” comes through directly. That’s why fans stick around. That’s why they come back.

Her April 2024 “Street Live VR” (sivr00332) combined her music background with VR. The scenario follows a romance that blossoms between a street musician and a fan who keeps showing up — review score 4.52 (48 reviews). It took her actual background and wove it into a VR experience. In a sense, it’s a work only Miho Nana could have made. That’s the advantage of an actress with a multi-layered career.

And then, just before retirement, “The Belated Youth” (sivr00446) — a scenario where a graduating school idol confesses her feelings to you. Review score 4.63 (27 reviews). Knowing her retirement was already decided when this was filmed adds a unique bittersweet quality that permeates the entire work.

3.5 Years in Four Chapters — An Absurdly Dense Career

When you line up Miho Nana’s solo works chronologically, they divide neatly into four phases. Even within such a short career, the stages of growth are remarkably clear.

Chapter 1: Explosive Debut (June–December 2022)

From her debut “Newcomer NO.1 STYLE” (ssis00447) through the hot spring date work (ssis00565), the first-ever major convulsion special (ssis00537), and the men’s esthetic work (ssis00591). Six solo titles in six months — a furious launch.

The defining feature of this period is that she was competing on raw charm alone. Technical acting skills, camera confidence, those acquired abilities were still developing. Yet her freshness and the sheer force of her smile were enough to consistently score above 4.0. The men’s esthetic work hitting 4.57 (49 reviews) marks the peak of this era. The blueprint for “healing through smiles” was established right here.

Chapter 2: VR Debut and Genre Expansion (January–December 2023)

The year her VR debut (sivr00248) in June blew up with 221 reviews. Simultaneously, she maintained monthly solo releases and took on daring concepts like “The First-Ever Praise-While-Getting-Reverse-R**ped in AV History” (ssis00767).

The standout here is the VR men’s esthetic work (sivr00299) — 4.49 rating with 67 reviews. When the “healing” formula she’d established in 2D was brought into VR, her fanbase exploded. It was the moment where medium and performer perfectly clicked.

She broadened her range into NTR (ssis00726), assertive-girl themes (ssis00767), and step-father scenarios (ssis00879), while dropping her original single “Koakuma Darling” in September. Her 1st anniversary best-of (ofje00424) also came out. An incredibly dense year.

Chapter 3: Stability and Depth (January–December 2024)

Her product codes switched to “sone,” and she fully cemented her position as one of S1’s flagship actresses. The VR lingerie maid work (sivr00316) scored 4.61 with 62 reviews, and her VR ratings only grew more consistent.

“My Student Goes Commando After School…” (sone00076) pulled 123 reviews. “Private VIP Service Nurse” (sone00158) hit 178. Solo works regularly crossing 100 reviews signals serious fan-base depth — not new viewers, but repeat customers.

Her 2nd best-of collection, “Beloved Solar System Beauty: Nearly All 21 Titles, 59 Sex Scenes, 12 Hours from Two Years” (ofje00452), crystallized two years of work. By this point, the “Solar System Beauty” moniker was firmly established.

Chapter 4: The Final Stretch (January–December 2025)

Even before the retirement announcement, the quality and ambition of her work stepped up a notch. “Him, Me, and the Manager — Late Night Shift: Live Action” (mimk00201) was her first manga adaptation, a joint S1 × MOODYZ production. Under the pressure of bringing a 220,000-copy manga to life, she delivered the emotional range an NTR drama demands.

“Locked in a Room Full of Muscular Men” (sone00764) scored 4.80. Her retirement VR work “I Always Want to Be Your Number One” (sivr00452) hit 4.74 — the title itself reading like her personal message to fans.

Her final release, “Real Fan Appreciation Festival” (snos00033), brought the curtain down on 3.5 years. Full effort until the very last frame. A retirement this thoroughly “complete” is genuinely rare.

Five Works That Showcase the Gap — The Solar System Beauty’s Range

If you want to fully appreciate Miho Nana, these are the five titles to start with. I chose works that prove she was far more than just “energetic and cute,” selected to follow her career arc.

The Debut: Origin Point and One of Her Highest Peaks

“Newcomer NO.1 STYLE: Miho Nana AV Debut” (June 2022). Rating: 4.42, 134 reviews.

Think about what those numbers mean for a debut work. S1’s newcomer debut series is one of the most closely watched in the industry, and even then, reaching the 4.0+ range is rare. The fact that 134 reviews poured in tells you everything about her first impression’s impact.

What this 19-year-old band girl showed in front of the camera wasn’t acting or pandering — it was pure, straightforward innocence. Plenty of people thought “this girl’s going places” from day one. I was one of them.

The Peak of “Healing” — Men’s Esthetic Work

“The Incredibly Cute Therapist Who Loves to Serve Will Heal and Please You with the Ultimate Smile” (November 2022). Rating: 4.57, 49 reviews.

Reached just five months after debut, this is her early masterpiece. The men’s esthetic setting was a perfect vehicle for Miho Nana’s greatest weapon: healing through her smile. The “divine service” in the title isn’t just marketing fluff.

What makes this work special is how the esthetic salon setting naturally showcases her innate warmth. It’s less acting, more like a real therapist is right there in front of you. The slow build from treatment scenes to gradually rising intensity is masterfully paced. If you’re into the healing genre, this is a bull’s-eye.

The Awakening — First Major Convulsion

“117 Intense Orgasms! 4,400 Convulsions! 1,800cc of Squirting! The Angelic Cute Girl’s Erotic Awakening: First Major Convulsion Special” (September 2022). Rating: 4.24, 59 reviews.

Three months after debut. Here’s where you see Miho Nana’s “other face.” Sensitivity and reactions you’d never imagine from her usual carefree smile. Even if the title’s numbers are production-enhanced, reactions this convincingly real are rare.

The cheerful solar system beauty, overwhelmed by pleasure, crumbling into someone unrecognizable. This gap is Miho Nana’s essence — the element that kept pulling fans back throughout her 3.5-year career. Watch this back-to-back with her debut and you’ll be stunned by the range in the same person.

Dramatic Range — First Manga Adaptation

“Him, Me, and the Manager — Late Night Shift: Live Action of the 220,000-Copy Series” (March 2025). Rating: 3.91, 11 reviews. A joint S1 × MOODYZ production.

A live-action adaptation of the manga of the same name with 220,000 copies sold. This was Miho Nana’s first source material collaboration, and within the NTR drama, she showed she could do more than just be cute — she could act.

Her experience performing on stage during her band days pays off in drama-driven works like this. Her emotional range goes beyond standard AV acting. A peak she reached in the latter half of her career.

The Final Full-Force Performance — Pre-Retirement

“Petite Cutie Locked in a Room Full of Muscular Men for 10 Hours” (June 2025). Rating: 4.80, 10 reviews.

Released roughly a month before her retirement announcement. That 4.80 average is among the highest ratings across her entire solo catalog. In a hardcore setting, Miho Nana’s physical ability and mental toughness are on full display.

It’s the polar opposite of her debut’s innocence, yet the core commitment to going all-in hasn’t changed. Everything she built over 3.5 years is packed into this single title. If you want to know how far she’d come by the end, this is the one.

VR Masterpiece — Her Unfiltered Self, Up Close

“Cute, Kind, Sexy. Happily Serving You While Gazing into Your Eyes Up Close: Instant Blowjob Lingerie Maid VR” (January 2024). Rating: 4.61, 62 reviews.

Miho Nana has 7 VR titles total, but if you can only pick one, make it this. The balance of review count and rating is the strongest in her VR catalog. The lingerie maid scenario perfectly complements her natural service-minded personality.

The smile looking at you through VR genuinely feels like she’s right there. Even in 8K VR resolution at point-blank range, her face doesn’t lose an ounce of appeal. And her expression during the service scenes — she looks so genuinely happy. This is an experience 2D simply cannot deliver. If you have VR, prioritize this. If you don’t, this work alone justifies the investment.

Who Should Check Out Miho Nana

• If you love the healing type but crave some gap appeal too: The contrast between her everyday smile and her intense in-scene reactions is staggering. A rare actress who delivers both
• If you’re looking for a VR starting point: 221 reviews on her VR debut says it all. The ultimate VR experience for soaking in an unfiltered, genuine smile at close range
• If you enjoy story-driven, scenario-based works: From school settings to NTR to men’s esthetics, her range across situations is spot-on. She even pulled off a manga adaptation
• If you want to follow a retired actress through her prime: With her December 2025 retirement, her full catalog is now complete. You can binge the entire growth arc in chronological order — a genuine luxury

On the flip side, if you’re after hardcore or niche fetish-focused content, she might not fully land for you. Miho Nana’s strengths are rooted in her personality and genuine reactions. She’s not the type who competes on technique or intensity — she’s the type who creates atmosphere through sheer presence. For those whose tastes align, she’s irreplaceable. Is she for everyone? Honestly, no. But that’s exactly why she hits so deeply for those she does connect with.

The Meaning of S1 Loyalty — The Pride of an Actress Who Never Transferred

One last thing.

Across her entire 3.5-year career, Miho Nana never released a single solo work outside of S1. She appeared in variety-adjacent projects like “Kachikochi TV” and “Tokyo Scandal Club,” but every solo-credited work was S1. Her product codes evolved from “ssis” to “sone” to “snos,” but the label was consistently “S1 NO.1 STYLE.”

That’s unusual in today’s AV industry. When an actress gets popular, offers from other studios inevitably come. Transferring means signing bonuses and access to new fan demographics. She didn’t budge.

Maybe she understood that her strengths shone brightest within S1’s production ecosystem. Her VR works’ high ratings owe something to S1 VR’s filming expertise. Concepts like “Street Live VR” that drew on her musical background were only possible because S1 understood her career.

She gave everything she had in one place, did everything there was to do, said “it was the most fun I’ve ever had in my life,” and walked away. I wanted this article to preserve the record that such an actress existed.

She Played Guitar, Sang, Acted, and Smiled. She Did It All in 3.5 Years

Miho Nana’s 3.5 years come down to one phrase: “She did absolutely everything.”

A girl who played guitar in a band knocked on S1’s door, nailed her debut with sky-high reviews, released solo works at one-per-month pace, earned top-tier VR support across the industry, dropped an original single, performed on idol stages, appeared on variety shows, published photobooks, hosted fan events, and produced her own retirement fan appreciation festival.

At 23. In 3.5 years.

The complete retirement box set releasing in April 2026 (all 39 works, 16 hours) will be Miho Nana’s final new product. It’s a chance to relive her entire 3.5 years in one sitting — literally a “complete record.” It’s not too late. In fact, now that everything is out, there’s never been a better time to watch from start to finish. Spend 16 hours following the journey of a 19-year-old guitarist becoming S1’s 23-year-old ace.
