Sometimes you'll just be going about your life when pow, oppai! At least that's the case if you're an anime MC like Sahashi Minato. He winds up becoming the master of Musubi, a busty warrior girl who is a contestant in a death game pitting other busty females against each other. She's airheaded, overly affectionate, and has no qualms about showcasing her curves. It doesn't take Minato long to amass an entire harem of other busty females who are all vying for his attention. If you like oppai and action, Sekirei has you covered.

If an angel wound up on your doorstep with the ability to grant you any wish you desired, hopefully, you wouldn't destroy the entire world in the process. That was the case with Sakurai Tomoki. He has become the master of the curvaceous bombshell Angeloid Ikaros, and his life is becoming more hectic by the second. Soon, more Angeloids begin to find their way into his life, much to the chagrin of his busty childhood friend Mitsuki. Truly, heaven is missing some oppai, but if you're looking for some, this anime is just the thing.

Bikini Warriors is the story of four beautiful but dimwitted adventurers who continuously find themselves getting into ecchi situations while traveling a fantasy RPG-like world. That's basically it. Each episode of the show is under five minutes long and by the end, the girls are always wearing fewer clothes than they started with, which by starting in bikinis makes it quite a feat. As expected, there's more oppai "plot" than story plot, but sometimes that can work too.

Who knew monster girls had such monstrous oppai? Japan apparently. Kurusu Kimihito, aka Darling, has become the host of a harem of women who look human on top but are monsters on the bottom. The government is trying to get him to get closer to the girls to prove romance can last between interspecies couples, but he's finding things rather difficult all on his own. Life for Darling might be a hassle, but fortunately for the audience, oppai are plentiful in this one.

After losing his parents in a tragic accident, Arima Teppei is adopted by his grandfather, the richest business owner in Japan. He is suddenly thrust into the lap of luxury and is quickly courting busty aristocratic beauties from all over the world. Based on a visual novel of the same name, the heroines definitely leave an impression. These princesses may or may not be royalty, but those oppai are a crowning achievement.

Otherwise unremarkable, Hida Kizuna possesses the ability to draw out a woman's power through lewd activities. Brought in to lead a task force of super-powered high school girls defending the remnants of a destroyed Earth from alien invaders, Kizuna does his job with gusto. Sensual scenes that have the censors sweating bullets, HxH is probably the riskiest non-hentai anime ever to grace Japanese airwaves. It knows its purpose and lives up to expectations in every way.

The dead are walking and the oppai are jiggling. Several teenagers are thrust into a zombie apocalypse and the females of the group are amply endowed with gratuitous fanservice scenes thrown in to keep the audience happy. While there is an overall story, despite the tone, you could never tell that the anime takes itself seriously. It has one of the most iconic scenes in oppai history, with character Saeko dodging a bullet between her breasts by having them contort independently. Forget the main cast or the zombies, oppai are the real stars of this show!

The world of Queen's Blade is full of swords, magic, warfare and...oppai. A show with a mainly busty female main cast, it tells the story of Leina Vance and her quest for independence. Declining her rich inheritance and sworn family duty, she opts to enter the Queen's Blade tournament and battle with other equally curvy beauties. There's plenty of violence and fan service to be found, making it an exciting watch.

All Ooyama Takeru wanted was to attend school with his busty childhood friend and flirt around. What he got was thrown into a martial arts society that would seem more fitting in Dragon Ball Z. Formerly an all-girls school, there are a lot of oppai-rich warriors at this school, and Takeru is getting close with all of them. The overall plot of this series is here today and gone tomorrow, but with all these oppai, who can complain?

A virus outbreak has thrown the world into a panic and all the affected girls have been sent to an island to quarantine them. The symptoms involve turning into weapons whenever lesbian activities are performed, and it’s a spreading epidemic. With only beautiful women on the island, it stands to reason there’d be plentiful oppai, however, this show has literally the biggest oppai probably to ever come from Japan. We’re talking actual circus tent bikini tops. No, it doesn’t make sense, but does it need to?

Manyuu Heikenchou takes place in the Taiheimeiji Era, with the Tokugawa shogunate in power. In a twist on the usual story, in this shongunate, big breasts mean big power. In fact, if you have small breasts, or no breasts, you are lucky to even be considered human in society. On the other hand, being well endowed by nature also means you will be wealthy and popular as well. Manyuu Heikenchou focuses on the tale of Chifusa, who steals a sacred scroll rumoured to hold the secrets to raising women with big breasts, hoping that with it she can change the world that has been created by the Tokugawa shogunate.

If after that description you are still wondering why Manyuu Heikenchou is starting out our list of the Top 10 Oppai Anime, well, allow us to point out that even the name of the anime translates roughly to “Magic Breast Secret Sword Scroll.” The very core of the plotline of Manyuu Heikenchou is about big oppai! So you can expect to see plenty of them throughout the anime, and of course they are attached to many beautiful, fighting women wearing traditional Japanese clothing that can barely contain their bursting boobs. If you like a more historical setting, or if you are looking for an anime literally about oppai, Manyuu Heikechou is a great place to start!

Triage X tells the story of the team at Mochizuki General Hospital – but there is far more to them than meets the eye. While by day, they may appear to be normal hospital workers, by night, they become the vigilante group known as the Black Label. This group has taken upon themselves to cure the “cancers” of society before they can spread by killing criminals that they do not see as worth trying to save. However, not everyone agrees with the Black Label’s form of justice, and they soon find themselves being pursued by the authorities, including one particularly adamant detective.

The leading ladies of Triage X are, as you can probably guess from seeing it here on our list, not lacking in the oppai department. You can count on seeing a lot of large breasts barely covered by underwear, clothing, bikinis and more throughout the series. Their oppai serve as a place to store weapons and more, and are prominently a focus of the scene regularly. If you are looking to see a bit of something darker, while enjoying a large cast of full-breasted women, be sure to check out Triage X.

Senran Kagura is the story of five girls training to become shinobi, spies and assassins that used to serve the shoguns in Japanese history. Instead of a historical setting, however, Senran Kagura takes place at a modern school called Hanzo Academy, where the heroines find themselves pitted against another group of darker, modern shinobi determined to prove their superiority. The girls have to learn to use their own shinobi skills to the best of their abilities, including being able to transform and work as a powerful team together, to come out on top and protect the reputation of Hanzo Academy!

With an all-female cast, you can already guess that Senran Kagura has the potential to be a hotpot of oppai – and you have certainly guessed right. All five of the main characters are large-breasted beauties, and you can count on seeing their oppai in action not only during fights and transformation sequences, but at the beach, playing volleyball, and more. If you are looking for a more light-hearted, but still exciting oppai-filled anime, give Senran Kagura and its five heroines a chance to prove themselves!

Hachimitsu Academy was always an all girls’ school – until now, when five boys are allowed to join. Before they can make a good first impression amongst all their new classmates, however, the boys take to trying to peep into the girls’ bathroom, and they land themselves in the school’s underground prison. Their choice is to either endure the prison for one month to pay for their crimes, or be expelled. Of course, they choose to stay in the prison, and face the Draconian laws and punishments that still exist in this prestigious academy!

Prison School is an anime that many people have been talking about lately, and for good reason – with high ratings and a large following, it’s a popular manga-turned-anime. But of course that isn’t enough to get it on our list of the Top 10 Oppai Anime. What is enough to land it here is Meiko Shiraki, the vice president of the Student Council that is set to punishing the boys. Meiko’s oppai are of gargantuan proportions, and they are prominently displayed through the entirety of the anime without shame. Her clothes can barely contain them, and sometimes, they don’t! Trust us when we say you won’t be disappointed checking out Prison School if large oppai are what you are looking for.

Queen’s Blade Rebellion is the sequel to the series Queen’s Blade, but don’t let that deter you from trying it out anyway. In this new story, the Continent has fallen under the tyrannical rule of a new sovereign – the Thundercloud Queen Claudette, the last victor of the Queen’s Blade competition. Annelotte, the main heroine, and her army of rebels lead a fight to try to overthrow Claudette and return peace once more to the Continent.

While that description alone may not make you think this anime should be a contender, don’t give up yet. Queen’s Blade Rebellion has an entirely female cast, and trust us when we say that their oppai are worth you tuning in for. If you like watching girls fighting against one another, especially wearing minimalist armour that can’t possibly be for protection but definitely has fan service in mind, give this anime a watch. The medieval fantasy setting sets it apart from the other anime on our list of the Top 10 Oppai Anime, and the boobs themselves are sure to leave you satisfied.

In Girls Bravo, the main character Yukinari Sasaki has a very rare and terrible condition – he is allergic to girls! In fact, when a girl touches or even comes close to touching him, he breaks out in horrible hives. One day though, Yukinari finds himself transported through a bathtub into the mysterious land of Seiren, a place populated almost entirely by women. Thankfully, he befriends the one girl whose touch does not affect him, Miharu Sena Kanaka. Miharu and Yukinari return to Earth together to explore, and soon, other women from Seiren follow them as well!

In a location that is populated almost entirely by females, you can imagine that there are going to be oppai abounding – and you imagine exactly right. An ecchi, harem anime, Girls Bravo has plenty of boob shots, swimsuit sequences, shower scenes, and touching to keep the interest of any oppai appreciator. If you want an anime full of laughs and oppai, look no further – Girls Bravo is just right for you!

High School DxD takes place at Kuoh Academy, a school that has not only normal students but also angels, fallen angels, and devils in attendance. The plot centres on a normal (though perverted) student named Issei Hyodo, who by “luck” is asked out on a date by Yuma Amano. Yuma, however, turns out to be much more than Issei expected – she is in fact a fallen angel, and kills him! Fortunately, or maybe unfortunately, for Issei, he is given a second chance at life by Rias Gremory, who reincarnates him as a devil – and as her servant!

Prepare for a lot of laughs, and plenty of risqué, ecchi oppai shots throughout High School DxD! The majority of the female cast is very blessed in the boob department, and their scenes don’t leave you waiting and wanting. If you’re looking for plenty of good oppai viewing, while enjoying a comedy story with a lot of intriguing characters – or maybe angels and demons really are what gets you going, then High School DxD is the one you will want to check out!

Seikon no Qwaser is about Mafuyu Oribe, Tomo Yamanobe, and Alexander "Sasha" Nikolaevich Hell and their time at St. Mihailov Academy. Sasha is Qwaser, a person that can manipulate a specific element to fight against others through the power gained by ingesting Soma – a magical element found in the breasts of women. With a serial killer after women at St. Mihailov’s, and a long string of other Qwaser after Sasha, Seikon no Qwaser has no shortage of fighting and action sequences as Sasha defends Tomo and Mafuyu and everyone tries to get to the bottom of the killings.

In the midst of all the action sequences in Seikon no Qwaser, there is plenty of oppai fan-service as well. When any Qwaser, male or female, is running low on power, they recharge their Soma by drinking from women’s breasts. The female characters featured in the anime range in size from small to large and everything in between, with something to make everyone satisfied no matter what your taste in oppai might be. So if you want an anime with plenty of fully-exposed oppai shots, as well as a real and engaging plot complete with good fights, then Seikon no Qwaser might be exactly what you’re looking for.

Rito Yuuki’s life is never the same again after the unexpected arrival of Lala Satalin Deviluke in To-LOVE-Ru. Lala is a princess to an alien empire, and she wants to marry Rito to avoid a political marriage back on her home planet! Although, Rito is just an average, and rather shy, teenage boy - can he really marry the princess of the most powerful empire in the galaxy? All he wants to do is confess his crush on his classmate Haruna! However, if Rito is unable to protect Lala from her many fiances, her father is going to kill him and destroy the world.

Sekirei tells the story of one boy, Minato Sahashi, and his bond with not only Musubi, the original Sekirei he bonds with, but his bond with several other Sekirei as well. Not only are the Sekirei fighting one another under the power of Minato in the Sekirei Plan, they also are fighting amongst themselves as they compete over him.
