Miyu Aizawa | From Idol & Nursery Teacher to Top Actress

The Story of a Girl Who Hit the Stage at 12 and Entered AV at 20

Five years as an idol. Two years as a nursery teacher. Then an S1 exclusive debut.

Line up her resume and it makes zero sense at first glance. I’ll be honest — I did a double-take myself. But watch a handful of Miyu Aizawa’s (逢沢みゆ, Aizawa Miyu) titles and that seemingly random background starts to click into place.

In just two and a half years since her debut, she’s racked up 288 titles. She’s gone on record saying there was a stretch where she was shooting 13 films a month. She walked away from S1 — the most prestigious label in the industry — on her own terms and carved out a new lane in the freelance world. This woman is no washed-up idol.

What Makes Aizawa Interesting: The Range

“Former idol goes into AV” — heard it a million times, right? But Aizawa’s case is different. Between stepping off the stage and stepping in front of the camera, she spent two years as a nursery school teacher, working with children every day. That gap gives her performances a depth you can’t quite put your finger on.

The knack for being loved by the camera, drilled in during her idol years. The ability to tune into someone’s emotions, honed during her time with kids. Both show up clearly in her work. The way she closes distance in intimate, lovey-dovey scenes has a naturalness that can’t be explained by experience alone.

Profile

Miyu Aizawa (逢沢みゆ, Aizawa Miyu) is an AV actress born on March 3, 2003. She made her debut in December 2023 as an S1 NO.1 STYLE exclusive, and has been active as a freelance actress since the latter half of 2024.

• Date of birth: March 3, 2003
• Height: 155 cm
• Measurements: B90 / W56 / H88
• Cup size: F
• Hobbies: Cooking, makeup, fashion
• Special skill: Remembering faces
• X: @Aizawa_miyu03

An F-cup bust of 90 cm on a petite 155 cm frame — the numbers alone are striking. But in motion, the impression is more nuanced than that. The interplay between her slender build and soft bust creates a kind of allure that’s hard to describe in words.

The Five Years as Idol “Maria Sakamoto”

Before entering the AV world, Miyu Aizawa went by a different name: Maria Sakamoto (坂本マリア, Sakamoto Maria). As a third-generation member of the idol group Flap Girls’ School, she devoted five years — from age 12 to 17 — to performing.

CD recordings, live shows, TV appearances. She poured her entire adolescence into the stage. But by her own account, she graduated carrying the frustration of “never having made it big.”

Her words on ABEMA’s “Kyuuyo Meisai” (給与明細) were telling: “I’d always been in the spotlight in some form, so something felt missing. I still had regrets from my idol days, and I thought maybe I could shine again in this world.” That hunger for the stage is what led her to a different kind of spotlight — AV.

What Those Two Years as a Nursery Teacher Built

After leaving the idol world, Aizawa became a kindergarten teacher. From roughly age 17 to 19, she spent her days caring for children.

At first glance, this seems like a detour on the way to becoming an AV actress. But I’d argue these two years were what fundamentally sharpened her instinct for connecting with people. Kids don’t lie. If they’re bored, they ignore you. If they’re scared, they cry. Spending every day with an audience that honest trains you in reading a room — and that shows up on camera.

That oddly real sense of intimacy she brings to her more tender work. The way she closes distance without it ever feeling forced. Personally, I don’t think she’d pull that off so naturally without those years as a nursery teacher.

From S1 Exclusive to Freelance: Taking the Wheel

December 2023 — debut on S1 NO.1 STYLE. The title “Newcomer NO.1 STYLE Miyu Aizawa AV Debut: The Complete Record of a Real Idol’s Transition to AV” leaned hard into her idol backstory as a marketing play. With 301 reviews and a 4.10 rating, those are rock-solid numbers for a newcomer.

Her S1 run looked smooth on the surface — steady release schedule, consistent quality. But something else was brewing internally.

“I’d been playing it safe with the standard approach the whole time. At some point I just got bored with it.” That’s what she said on ABEMA’s “Kyuuyo Meisai,” and in the second half of 2024, she voluntarily dropped the S1 exclusive tag and chose the harder path of freelance work.

With new faces debuting constantly, she felt the pressure of “gradually getting buried.” Her answer was to work with more studios, tackle more genres. When you hear she was shooting 13 titles a month at her peak, you start to understand just how much conviction that decision required.

A Title That Proves Her S1-Era Talent

This was her highest-rated release from the S1 exclusive period. A review average of 4.80 speaks to her potential.

The way her expressions shift during intense scenes is exceptional. Her teasing technique carries traces of the idol-era polish — she knows exactly how to play to a camera, and it shows.

The Freelance Glow-Up

Since leaving S1, Aizawa has — and I say this without exaggeration — transformed.

S-Cute’s “A Day Off with Your Girlfriend” pulled a perfect 5.00 review average. Set around a hot spring trip — an everyday scenario — it’s a masterclass in the natural intimacy that is her calling card. S1’s polished production had its merits, but a more relaxed environment might just suit her better.

DAS! (ダスッ！)‘s “Sudden Downpour on a Business Trip” earned a 4.71. The setup — forced to share a room with a boss she despises — lets her showcase a compelling emotional arc from disgust to pleasure. This is exactly where the expressiveness drilled in during her idol days pays dividends.

Yuuyake Jealousy (夕焼けジェラシー)‘s “I Love It from Behind!! A Beautiful Butt FWB” also scored a perfect 5.00. The fact that she’s pulling top marks in a POV format — the polar opposite of conventional studio work — is telling. Delivering results regardless of studio or format is proof that the move to freelance was the right call.

Her Photobook Work

Aizawa’s appeal isn’t limited to video. Her first photobook, “Souai” (相逢 sou-ai), shot by Kyosuke Tomita, was published by Futabasha and was well-received among fans.

Her digital photobook for Shukan Post, “Former Idol, F-Cup Nude Debut,” also made waves. The boldness is a far cry from her idol days, but she manages to keep a certain elegance throughout — and that’s very on-brand for her.

Who This Actress Is For

• If you want to see what a former idol looks like when she’s all-in: The camera presence and expressiveness she built on stage are unmistakably at work in her AV performances

• If lovey-dovey and intimate content is your thing: The natural sense of closeness she developed as a nursery teacher gives her pseudo-romance titles an unmatched authenticity

• If the petite-with-F-cups combo gets you every time: 155 cm and an F-cup. What that looks like in motion — just watch one title and you’ll see

• If you like following an actress across multiple studios: S1, DAS!, S-Cute, Honnaka, unfinished. Going freelance means you get to appreciate the different flavors each studio brings out in her

Conclusion

Idol. Nursery teacher. S1 exclusive. Freelance powerhouse. This 23-year-old gave everything she had at every stage.

Dropping the S1 banner by choice took serious guts for a second-year actress. But the results speak for themselves — her range and ratings have only grown since going freelance. Someone who can accurately read her own strengths and pivot accordingly is built for longevity in this industry.

As of March 2026, she’s at 288 titles. She’s still only 23. Miyu Aizawa’s career might just be getting started.
