Thick Trend in JAV: Tina Nanami’s Phat Ass, Yui Hatano’s Meaty Tits, and Momona Koibuchi’s Jiggles

Published : March 1st, 2026 Written by Fried Chikan

Slimness has been the modern beauty standard for ages now. Before Ozempic, we had Intermittent Fasting, before that Keto diets, Pilates, Shake Weights, and countless other supposed weight loss cures. Outside of the emergence of the Plus Size and Body Positivity movement, thinness is still king for most of the world and especially so in Japan and JAV. And this is what a lot of JAV fans love about the talent: they are far slimmer and skinnier than many of their foreign counterparts. However, there are some JAV actresses bucking the Skinny Trend. Actresses who have put away the diet cures and have packed on the pounds for whatever reason. From full-bodied babes, to curvy chubsters, to Big Beautiful Women (BBW), these are the JAV Actresses on the Thicc Trend.

Tina Nanami

Seeing Tina Nanami today messes with my brain because I remember her way back in the day when she was starting out with SOD in 2019. Back then, she was rail thin, going for that skinny fit look at the time. You know that look where they aren’t that muscular but look like it because of their low body fat. She was into Bodybuilding and even participated in some events. Well, thankfully, she gave that up because in just a few years, Tina went from Sticc to Thicc. Now she looks like a totally different person.

From This

That small, rock-hard, and bony ass has been replaced with a big and fat dumper. Her small tits have also jumped up a couple of cup sizes. I was a fan of thin Tina before, but I have to say I like Big Tina even more. The roundness and fullness of that fat ass with the rest of her curvy self, there aren’t many like her in JAV. This newer Tina has been working in more mature-leaning studios and works with Attackers and Madonna. Which tracks as the mature 30-something year old has only gotten finer with time.

Yui Hatano

Yui Hatano continues to reinvent herself even in year 18, yes, Yui’s porn career is old enough to do porn now. Yui has changed over the years; she’s gotten more work on her face, over the years and her body has gotten a super-sized order. Yui now sports a pair of big tits and a huge ass to boot. So big that they even seem enhanced. It’s hard to tell, but it’s not to enjoy the new and thicker Yui. I have always thought Yui had a very underrated body. She always kept it very tight for most of her career; her small tits were beautiful, and she had a sizable booty with wide hips.

Yui Hatano

This version of Yui is a different one, but you can be a fan of both. What hasn’t changed about Yui is her performing. Nearly two decades in porn, and she is the picture of consistency and still pumps out the videos. Her body might change, but the same great Yui still exists underneath that jiggling tushy.

Momona Koibuchi

On this list, we are going to see a lot of older names, which makes sense. As you get older, it is common for people retain and gain more weight. So, it’s a small surprise when you see younger actresses start packing on the kilograms. Which is what is happening to Momona Koibuchi. Momona debuted with a normal-ish weight, not slim by JAV’s skinny standards but not all that chubby. Well, she’s real chubby now, and that extra weight gain is doing wonders for her already huge tits. Her big floppy tits have turned into heavy fat tits, and I think they look even better now.

Yuria Yoshine

Yuria Yoshine started out on the chubbier side, but I always marveled at how slim her waist-to-bust ratio was. Her M cups seemed much bigger in comparison to her body, and now they’ve gotten even bigger. Current Yuria has added on some rolls to buff up those M cup into meaty K cups. Lots of people will check out Yuria because of her big floppies, but she’s also a genuine hardcore actress who has done all sorts of videos from Anal to IR.

Chanyota

The weight gains of most actresses are usually not by design, except for Chanyota. The bodybuilder slash pro wrestler slash porn actress was always gearing up to pack on mass. You can see it in her early videos as she was putting on more weight and, over time, started to cultivate muscles. The weight and muscle she put on were much more functional than for show, like a bodybuilder. The Chanyota of today is a whole lot mightier and built than the debut Chanyota. And she needs those muscles around the ring to suplex, grapple, and body slam her opponents. What a shame she left porn when her body was reaching new peaks.

Maria Yumeno

I might be the only one who remembers when Maria Yumeno was skinny. This was very early in her career, but I still remember fondly seeing old and grainy clips of early Maria. She would eventually size up and get a pair of big tits, which would be her look for most of her on and off career in porn. She’s come back again to porn, and this time she’s gone jumbo-sized. Honestly, her massive breasts defy belief. Looking at her from her debut to now, my mind is hit with confusion.

Came Back Big

Here are some names that retired and came back thicker. First was Asahi Mizuno, who was much beloved for the tight curves and dominant performance. However, when she came back with a bigger body, fans weren’t very excited, and neither was she if we are honest. It wasn’t a surprise when she quickly left again. Minori Hatsune was a big star when she debuted all the way back in the late 2000s. When she came back, she did so with a bigger body and a more mature look. Since coming back, Minori has kept a very low profile and appears in the odd title from time to time.

Full-bodied Fine

Not everyone here is putting on a ton of weight, just like in the case of Tsubaki Sannomiya. Tsubaki has just filled out her body more, with some of it coming from muscle mass. It really complements her body and makes her enhanced boobs look even better and stand out less. Mahiro Tadai has added a bit of mass, with most of it going to her ass, which this Ass fan thanks the JAV gods. Just like with her fellow SOD actress, Rei Kamiki has put on a few pounds since debuting. Looking much fuller figured and normal weight, well, normal for a non-JAV actress. Haru Minato was on the chubby side when she debuted with her massive K-cups. Now, as Haru Minami, those K cups have turned into M cups. The rich get richer, the busty get bustier.

Other Thickness

It’s hard to imagine a Nina Nishimoto that isn’t the plus-sized bombshell that she is now, but that is the truth. Before turning into a BBW blonde babe, Nina was a much slimmer but still curvy brunette. The size increase was a big boon for her career, as she herself credits. I am not the biggest Shiori Tsukada, but I can’t deny she’s got one of the best bodies in JAV, all-time. She’s got the right amount of size in just the right places; her curves are crazy. There was a day when Shiori was just a mere mortal who was only somewhat chubby, but that was the case in her early days. The same is true for Nene Tanaka.

Nina Nishimoto
Reo Fujisawa

Now these ladies never got on the Thicc Trend because they were always thick, like with Yumi, Kazama, June Lovejoy, and Reo Fujisawa. Reo was always a big lady, even when she first came into porn. I think quite a few fans become BBW fans as a whole thanks to her. She had a big figure, but it was quite shapely. As her career progressed, she added on even more weight. Going further down the BBW wagon.

Rei Kamiki

Outside of the mainstream space, with the big studios, and makers are plenty of thicker and bigger ladies in JAV. While these types are not my main jam, if we are being honest, I do appreciate a wide range of figures. In JAV, it’s rarer to see actresses gain more weight, so it is nice whenever they do buck the trend.


Who are some of your favorite actresses on the thicker side? Sound off on those curvy ladies below.
