Japanese is fundamentally a very playful language, full of quirky wordplay thanks to its phonetic readings. Longtime J-List readers will know that November is filled with many “good [something]” days to celebrate. For example, the beloved Good Oppai Day is celebrated on November 8 (because 11/8 can be read as いいおっぱいの日, or ii oppai no hi). Today, November 4, is ii oshiri no hi, or Good Butt Day (sometimes celebrated on November 30 as well). So, let’s take this perfect opportunity to examine the very best butts, via the medium of butt cosplay!
J-List has not one, but two new offers for you! First, we’re running an 18% sale on all books and magazines, including all hentai manga and doujinshi from Japan, and all sexy JAV photo books. Then, in order to combat the rise of No Nut November, we’re giving you a rare $40 coupon off of $200 or more in awesome onaholes, ero lotion and more. Two ways to save with J-List! Both sales end November 11th.
What Makes a Good Butt Cosplay?
Regular readers of our cosplay column know how much effort cosplay shoots require. From outfits and locations to makeup and photography, even the simplest cosplay shoot is quite involved. But accounting for an erotic element with good angles ups the difficulty further. Most cosplay photoshoots produce dozens of professionally produced shots, often available on the cosplayers’ Patreon pages or in photobooks.


Right, Alina Becker’s Yor Forger has another deadly weapon — that incredible ass!
A good ass cosplay needs to be instantly recognizable as a specific character, while also showcasing the cosplayer themselves. It might sound easy at first, but taking a good ass photo requires finding the right pose, lift, bend, or more!
We’re pretty sure we could identify some of these cosplayers by just their butt alone. That’s either an excellent party trick or a worrying sign of cosplay addiction… Well, our keen eye for a perfect peach helps bring you great cosplay butts like these!


Right, Tatsumaki won’t go down without a fight, not with JyuSan’s perfect peach on display!


Right, AloeVeraIsKawaii reminds us to concentrate when taking Marin Kitagawa’s hip measurements!
Anime Butts and Nothing But
What is it about the humble derriere that’s so appealing? Is it some primal instinct, or a sign of higher intelligence? (No, we’re not biased. Why do you ask?)
Scientists think attraction to butts comes from a mix of evolutionary biology, health signaling, and cultural conditioning. We’re willing to accept a far simpler answer: It’s because a good butt is eye-catching and provokes an immediate need to squeeze, like one of those squishy toys in a gacha box.
Speaking of squeezing, if Good Butt Day has you pining for a peach, check out J-List’s range of butt-focused onaholes. Why settle for just a silicone cylinder? You can have a realistic and weighty onahole with the Natural Ass Stimulation Toy by REAL the REAL!


Right, Blosmere’s Nami is looking for treasure, but the real booty is right under her nose!


Right, WinWinry’s 2B has a perfect android ass!
And the Best Butt Cosplay Winner Is…
Our favorite cosplayers have dared to bare it all in their butt cosplays. Some girls are naturally better at showcasing their rounder, plumper asses. Don’t let that fool you, though. We graciously accept all butts here! Whether small muffins or full bakeries, a cake is still a cake, and we’ll happily stuff our faces.
Don’t forget to check out the special “Cute Butt” section of the J-List store, where distinguished admirers of the finest asses will find doujins, onaholes, JAV, and more, all focused on the humble butt!



Right, Asuka fires right back with a mesmerizing butt cosplay from Ryo Kizuchi!


Right, routine exercise gives you excellent glutes, and Kitt3y proves that with Varesa’s cosplay.


Right, Love and Chunibyo might be delusions, but Rikka’s butt isn’t, courtesy of Smeepsx’s cosplay!
Cultural moments like Good Butt Day make us so grateful for Japan. Sexuality shouldn’t need to be repressed or hidden, and enjoying a good butt is definitely worth marking on your calendar. Thanks to the spread of Japanese culture through online fandoms and otaku circles, we get to see our favorite anime waifus cosplayed for us connoisseurs to enjoy. Arigatou, Nihon!
