Ever watch an actress and think "man she's got plenty of potential to be a big-time star" only to find out she's retired already, or has a limited catalog of videos, or is just a flat-out terrible performer? I've gone ahead and compiled a list of my personal top 10 most frustrating actresses in that regard, both past and present. I'll count down from 10 to 1 starting with the least frustrating to the most frustrating at the very end with reasons provided. With that out of the way, let's begin.

10. Rie Tachikawa

Rie Tachikawa may not have been one of the most well-known actresses around in her time but she certainly had a top-tier chest that made her appeal to any big-time bust enthusiast. Now my frustration surrounding her is due to two reasons. One is her very subpar performances. Her acting was never that great sadly. Very weak energy and facial expressions all around. But maybe worse than that is her disappointing filmography. She was only active in censored JAV for roughly a year before doing a handful of uncensored shoots which unfortunately was the death kneel to her career. She quietly vanished after that and hasn't been seen or heard from since. Those big natural tits were amazing and I just wish we got to experience more of them.

9. Kokoa Aisu

Oh how I loved Kokoa Aisu. She was such a petite "shortstack" with a booty that would blow you away. For someone so small her ass was incredible. And she was a real cutie too. That's why it's such a shame she never quite reached the heights I was hoping for. She was around for a good while before seemingly going into quiet retirement in 2016 disappearing without any fanfare. But then in the middle of 2017, she returned but only for about six months. And even then her return didn't really yield many quality films and felt like a cash grab for her. It's been radio silence from her since then so it's safe to assume she's done. Other petite actresses with a sizable booty have come along since like Ichika but Kokoa's ass was just on another level.

8. Yumi Shion

Yumi Shion is an actress that on paper should be a big favorite of mine. She's got big natural tits, is delightfully plump, and has a decently big booty. But for whatever reason, I just haven't made the leap to being a full-on fan yet. I want to become a fan but every time I watch a film of hers I'm left sitting on the fence. I like her body but something is missing and I can't quite put my finger on it. Perhaps it's her acting which isn't terrible per se but could definitely be a bit better. Her films as well often leave a little something to be desired. She's still active at least although now as a freelancer instead of an Oppai exclusive. I'm a bit worried she'll fizzle out but hopefully, she can spread her wings a bit and deliver some standout films.

7. Tsukasa Aoi

I've only recently discovered Tsukasa Aoi but already feelings of frustration have begun setting in. Don't get me wrong, she's still one of my favorite actresses at S1 and I've become a big fan. And the quality of her films is mostly pretty solid. So what's the issue? Well, it's all down to her subpar acting. I'll admit that in her previous two releases, her acting has seen a bit of an uptick. But before that, she was painfully lackluster. Just low energy, lethargic, and mostly static facial expressions. It severely limits the satisfaction of her scenes no matter how stunning her body is. I expect much better acting from someone who's been around in JAV since 2010. As I said there are signs of improvement which is promising but it shouldn't have taken over ten years.

6. Ai Kano

I won't deny that Ai Kano is a massive guilty pleasure for me. I know she's had a fair bit of work done on her face and her stomach looks off from the fat transfer surgery she had done on her chest. But I really love her huge tits and slim waist as she's got that perfect hentai milf look. The major reason she makes this list is definitely due to her underwhelming performances. She's always quite stiff with middling facial expressions. A little more enthusiasm would go a long way. It's also particularly frustrating that she seems to be done with JAV at the moment. According to her Twitter, she's back to working at a soapland. Perhaps she just used JAV to boost her sex worker career. I hope she comes back regardless, even if her acting is subpar.

5. Ena Koume

While making this list Ena Koume was one of the names that popped up in my head right off the bat. The reason she's a leader for this post isn't necessarily due to a lack of content although her output could certainly be better as oftentimes her new releases are from lower-tier studios or starring in a collab with another actress. The worst offense is her painfully average at best performances. Besides a few moments here and there, she's always quite laidback and devoid of any real proper enthusiasm. It's incredibly frustrating as her figure is sublime. She's got just the right amount of meat on her with amazing natural tits to boot. I still enjoy watching her don't get me wrong but that satisfaction is severely limited due to her underwhelming acting. 

4. Rara Anzai

Who else but Rara Anzai? I know it's like beating a dead horse but she's the epitome of a frustrating actress. The biggest and most obvious reason she cracks this list is due to her ever-persistent mediocre acting. From the day she debuted to her most recent film, her performances have barely changed. She's gotten slightly better sure but after nine years you'd expect much more. It's especially painful as her body is incredible and obviously her natural tits are some of the best but it's hard to enjoy when she lays there like a dead fish. It's also frustrating when she keeps going on a hiatus and coming back several times over with no social media presence at all. At this point she seems to be done yet again but who really knows? Only time will tell.

3. Alice Kisaki

Man, I was really wrong about Alice Kisaki going into 2022. Alice was making some noise near the end of 2021 and had the potential to be one of the next big busty starlets but instead faded out into obscurity. Her entire 2022 release schedule was bleak and depressing with not only minimal new videos but if there were any you could bet on them being with C-tier or worse studios. Or just multi-actress films. Her performances haven't gotten better either which makes her even more frustrating. She's got so much potential as her body is stunning with some of the best natural tits around and a firm, juicy ass. Unless a miracle happens I don't expect much of a turnaround sadly. Such a shame to see her fizzle out.

2. Nana Fukada

The bustiest stars burn out the fastest. That's how that quote goes isn't it? If you were a fan of big titties then I'm sure you're well aware of Nana Fukada and how disappointingly short-lived her career was. She debuted in December 2016 for E-Body before transferring to S1 in 2017. Then in February 2018 she released her final film with them and dipped out never to be seen again. It wasn't even a retirement film. Making matters worse was her utterly terrible acting. It was so painful seeing such a great body with some of the best natural tits you'll ever see just go to waste. Unfortunately, she just ended up as another big titty actress with wasted potential that couldn't act at all. Now, where have I seen that before?

1. Tomomi Motozawa

Now we've reached my overall number one most frustrating actress in all of JAV with Tomomoi Motozawa. This one is especially painful. I mean just look at her huge booty She by far had one of the best asses I'd ever seen in JAV. And unfortunately, it all went to waste. She was only around for a short period of time from early 2013 to mid-2015. During that time she released just a handful of films. Most of these were either multi-actress releases or just with C-tier or worse studios. You can count the semi-worthwhile films from her on one hand. Making matters worse was her awful performances. Her facial expressions were completely detached from what was happening and she was consistently low energy. It's so frustrating thinking what could have been.
