Published : April 1st, 2025 Written by Fried Chikan

Let’s take a look at Sumire Mizukawa’s restarted YouTube channel. Part vlog series that documents her travels abroad, part questionnaire with her answering fan mail, and part interview series with her chatting with fellow actresses. Consider following her channel here or with the video links below.


And if none of that interests you I will include clips of her working out and the end of this piece. For now, let’s dive into some juicy stories.

Sumire’s Start

First, some fan mail questions as she reveals that she entered AV at 20 years old and not 19 which was advertised. Her story of getting into AV isn’t very interesting she apologizes. She was a model at the time doing promotional work and mistakenly signed a new contract that would’ve meant she wouldn’t be able to work for some time. So, not wanting to wait, she took on AV work. Her reason for doing AV wasn’t particular, a common story of model/Gravure going to AV she says.

Sumire is Married?

Yes, her Wikipedia (JP) page is correct, Sumire admits that she is married in the US to an American. She left him because he was a psycho, her words, and they never officially proceeded with divorce papers so she is still technically married in the US. Not registered in Japan however so she’s single, she playfully flirts. Sumire realizes this can be a problem if she ever wants to get married in the US but that’s a problem for future her.

Vampire Boob Job

Sumire reveals that she has had a boob job after entering porn. A minor non-surgical cosmetic procedure called a PRP Insertion which is also known as a Vampire Breast Lift or VBL. It takes a person’s enriched plasma and they insert that into their breasts. Apparently, it stimulates collagen production and rejuvenates the breast tissue. Supposedly its effect is slight and temporary so it wears off eventually and even then, the science behind it isn’t universally accepted.

Sumire herself though swears by it and that it made her boobs bulgy. Looking at her debut title and titles later on and you can see a visible change. Whatever she did, it looks great and better than your typical implant job. She also mentions that as an adult she no longer wears bras which is not very relevant but very nice.

Working JAV vs Working Western


As someone who has worked in both JAV and Western porn, she talks about the differences in the industry. For her Western works, she mainly shoots in France and Hungary. Now for JAV, they work from dusk to dawn and while they work the whole day for Western too however they are much laxer than the JAV. JAV production workers work much harder she says. She also mentions that in Europe they do STD testing far more often, once a week.

Sex Preferences

Now she gets into her sexual preferences. A big fan of doggystyle and the lying down positions too but when it is time to come cowgirl is the way for Sumire. Cowgirl is easily her favorite position because of how she can grind in that position and get off. A fan asks if she will ever do anal and she says flat out No. She has tried getting into it but it was very uncomfortable and if she doesn’t enjoy it personally, she wouldn’t do it on screen.

As for her private life sex, she reveals that no she doesn’t have sex outside of work a lot. A common answer from actresses. And while she does love to party, she doesn’t do one-night stands or flings. Also, that she has to be careful due to the nature of her job.

Chatting with Yuki Takeuchi

Next, she chats with Yuki Takeuchi as they answer more reader mail. The first question asks “Is Filming AV Scenes Pleasurable for Actresses?”. To which the pair answer that it depends on the scenes. First as AV actresses they are more focused on putting on a performance, a show for the viewers so that can takeaway from their own pleasure. But in the right scene and with the right chemistry with their co-star, yes it can feel very pleasurable.


Yuki: But if the acting and chemistry with the co-star are great, I do get really into it.

Sumire: Same! If the other actor is really in the moment and treating it like real sex, I can get lost in it too.




Yuki: Same! But I won’t lie—there have been times when I felt something lingering afterward.

Sumire: Oh? Like, you thought about them after filming?

Yuki: Yeah, but it’s not the same as falling in love. It’s more like… a temporary afterglow.

Following up on that another question asks if they have ever fallen for their co-stars. To which Yuki does admit to developing feelings in the moment. Not quite love or attraction but when they are acting and getting into the moment, sometimes feelings of attraction do come up. It’s not quite the real thing and that once the scene ends and reality kicks in the feeling passes.

 Watching your own Porn

Another reader asks if they ever watch their own porn, a question I am always curious about, to which they admit to but not for the reason fans do. Both will watch their own videos to learn from them or to see how the video turned out. This is not the first time we’ve heard about actresses watching their own porn to take notes. It is funny to think of actresses watching their own videos and going “What am I doing here, why am I making that face?”.

  

Yuki: Right! It’s like reviewing game footage if you’re an athlete.

Sumire: That’s a great way to put it!

Looking this good takes work: Cospuri

Chatting with Riko Hoshino

Next, she chats with Riko Hoshino and the two are clearly buddies with how spoke with each other. They get started talking about their preferences in men, while Riko likes her men to be strong and muscular, Sumire likes all types. She talks about dating all sorts of men from tall to chubby and how when she was younger, she really preferred older men. Now that she’s older, that geezer fetish has lessened and she’s open to other ages. After that, they moan about shooting the movies specifically picky directors who spend way too much time trying to get a small shot perfect and how that adds to the shooting time.

Yuki: Okay, well… one time, I got a cramp in the middle of a scene.

Sumire: Oh no, where?

Yuki: My leg! It was so bad—I was trying to keep going, but my face must have looked so weird.

Sumire: Did your co-star notice?

Yuki: Yes! He was like, “Are you okay?” and I just tried to play it off like, “Oh, totally! Let’s keep going!” But inside, I was dying.

Physical Demands

Bouncing off of that they talk about the physical demands of the job and how hard some positions can be on their body. Before Yuki was asked about an embarrassing moment during filming and she mentioned how she got a cramp in one position but had to power through. While Sumire and Riko talk about how hard keeping their bodies in shape and their looks pristine even saying how unsure they are about how long they can keep it up for the job. However, Riko is aware that she only shoots once a month and that gives her more time to recover. Which means that she should go harder during her filming. This just highlights how much harder it is for freelancers who shoot a love of movies. The difficult and hard work schedule of JAV is one reason why Sumire likes shooting in the West as they are laxer.

Harder than it looks: START-174

Riko: "Yeah, and as the night goes on, it just gets harder and harder."

Sumire: "I know what you mean. Sometimes, you just feel like, 'This is my last scene, I swear!' But then they hit you with a three-person scene at the end!"

Riko: "That’s the worst! You’re already exhausted, and then they’re like, 'Alright, let’s do a 3P or 4P scene now!'"

Sumire: "At that point, you’re just like, 'Fine, do whatever, just let me survive this!'"

Miscellaneous details

Now for some various tidbits that she dropped during her videos. Sumire talks about her Takoyaki shop which is real and she runs it herself. By the sounds of it seems more like a pop-up shop. She talks a lot about her love of wine especially red. When asked about what she would want from another actress she mentions being a fan of Rola’s face which I assume is Rola Takizawa. When abroad she talks about taking Pilates to stay in shape and mistakenly joined a class filled with pregnant women. She also talks about filming being halted due to a Coronavirus outbreak on set in Hungary.
