In Japan, [[AnimationAgeGhetto the taboo of animation being for kids]], while still there, is less strict and what is considered inappropriate [[ValuesDissonance differs compared to most Anglosphere values]]. Censorship is minimal for what can go on a bookshelf. In Japan, the censorship of genitalia means a little black bar over the clitoris and foreskin of the penis. But not everybody in the western world knows this and so... well... you get the idea. Their most kid-friendly animations were those ''deliberately'' written to be also exported to the west. As a result, something is always LostInTranslation.

And manga? Hoo boy, there is ''literally'' no taboo about manga being "just for kids". Manga is a completely valid, expressive art form... which means content runs the entire gamut from sweet pre-K fluff to things mentally unprepared ''adults'' will struggle with.

'''"WARNING: Absolutely Not For Children" say their cover labels. Let's just say any and all {{hentai}} is not for kids and just leave it at that. So no examples, okay?'''
----
* ''Manga/{{Akira}}'' was first released in an English dub in the late 1980s. The film managed to break Japan out of the AnimationAgeGhetto in American eyes, containing a lot of violence (including a few exploding heads, people being smashed, and blown into gibs), a near rape scene, and a few utterly disturbing sequences. It even had strong suggestions of homosexuality in some characters - which back then was far less hilarious than it is today. The original manga, of course, amps this all UpToEleven.
* ''Anime/AngelBeats'', despite the cute and fluffy title, features chest stabbings, multi-story falls, and gunshot wounds in the stomach. And that's just the first episode.
* ''Anime/BloodC'', which is an original anime by ''Creator/{{CLAMP}}'' was featured in the cover of a Philippine otaku magazine for kids back then. But just because CLAMP made cutesy and fluffy works doesn't mean it's for kids. Just imagine what would be one's reaction when they found out that there's a nude scene of Saya in the bathtub and lots of gore in it with characters being EatenAlive [[spoiler:including one character who got ripped in half]].
* ''Manga/{{Bokurano}}'' 's opening and credits imply the show is ''a lot'' more light-hearted then it really is. The first episode doesn't help either; it looks like any {{shounen}} series about robots.
* ''Anime/CatSoup'' is very easily mistaken for a kid's film since the main characters are [[RidiculouslyCuteCritter adorable]] [[FunnyAnimal cartoon]] [[CuteKitten kittens]]--except that it's a GrotesqueCute SurrealHorror that's liable to disturb most ''adults''.
* ''Manga/ChaosicRune'' takes place in a world where people fight using monsters, machines, and magical spells that [[CardGames all come from cards!]] The most powerful cards are said to be the dragon cards and the main character has what is said to be the most powerful of all the dragons! Sounds like a great plot for a ''Anime/YuGiOh'' ripoff, right? Wrong. This is one of the biggest boobs and [[BodyHorror guts]] {{seinen}} manga out there. The most powerful dragon the main character commands? [[NamesToRunAwayFromReallyFast Its name is Death Rex]] and it comes in four parts, each qualifying as one SERIOUS EldritchAbomination. There's also plenty of horror to go around.
* ''VisualNovel/{{CLANNAD}}'', especially during the last third of After Story. It's got a cute art style, little mascots called "The Big Dango Family", and sakura petals abound... the perfect anime for your six-year-old girl, right? Wrong. The story, among other things, deals with drugs, parental neglect, [[spoiler: and the death of a mother AND her child,]] with [[WhamEpisode Episode 16]] and beyond of After Story being massive Tear Jerkers. [[spoiler: To be fair, the series retcons the deaths this in its ResetButtonEnding, but the implication is that it still happened, and that this is an altered version of events.]]
* ''Anime/CowboyBebop'' of all shows suffered from this when it initially ran on TV Tokyo. It ran Fridays at 18:00 (6 p.m.), a time previously occupied by G-rated or almost-G-rated shows like ''Manga/KodomoNoOmocha'' and ''Anime/AkazukinChacha''. The show only made it through half of its initial run due to its strong violence and adult themes.
* ''Manga/DoujinWork'''s box art and summary for its anime+manga combo pack and DVD case make it seem like a series about teenagers finding friends and a community through drawing their own comic books. In fact, the series is about the antics of friends drawing hard-core porn'.
* ''Anime/FantasticChildren'', despite its simple art style and title, isn't really for children, not so much because of explicit content (there is little) but because of an abundance of unsettling and often tragic plot twists.
* ''Anime/GingaDensetsuWeed'' is about talking dogs. Including a dog who ''castrates his enemies.'' You know, for kids! Don't get started on the manga.
* Those picking up ''Anime/GraveOfTheFireflies'' thinking it to be cheery Ghibli fare are treated to maggot-infested corpses and children dying of starvation. Light-hearted! It is occasionally placed in the kids' section, and yes, it was originally made as a double feature with ''Anime/MyNeighborTotoro'', but the entire movie can be summarized with "FromBadToWorse". Not to mention that some DVD prints of it say "Suitable for ages 3+" on the back cover. You'd think the word [[NeverSayDie "grave"]] would be enough of a hint, though. It's even more so in the recent releases because it has a TV-PG rating. Even worse, the German release was rated '''''6 and up'''''
* ''Anime/GregoryHorrorShow'', quite honestly, seems innocent enough; sure, it has "horror" in the title, but the fact that it has an anthropomorphic mouse as the main character means it could easily be mistaken for something along the lines of ''Literature/{{Goosebumps}}''. However, once you get to Catherine in episode 6, a snake nurse who [[spoiler: makes orgasmic moans as she draws your blood through a syringe]], things start to get a little rocky. Later on when the "splitting headaches" of Mummy Dog and Mummy Papa show up, there's plenty of NightmareFuel to show this is far from a show for children. Believe it or not, it was created by the same person who created ''Anime/{{Pecola}}''. Thankfully, Netflix re-categorized the series from "Kids and Family" to "Anime Horror" after complaints.
* ''Manga/{{Hellsing}}'': For some unknown reason, the Dark Horse publication rated it as T for mild language and violence. Because the numerous times the word fuck is used, scenes of extreme {{Gorn}} everywhere and two [[spoiler: rape scenes]] are ''definitely'' mild!
** The first volume of the anime was rated 10 in South Korea (meaning you have to be 10 or older to purchase; by comparison, even tamer shonen usually get a 13 or 13PG). The ratings description writer notices its 'frequent' (quite an understatement) violence, but also its 'fantastical' context...basically saying "it's a cartoon, it can do whatever it wants and it's kid-friendly."
* ''VisualNovel/HigurashiWhenTheyCry'':
** Listed as a series belonging in "Kids and Family" by Blockbuster video's computer system. This is a series where ''[[RRatedOpening the very first scene]]'', before even the opening credits, involves two (now dead) girls being brutally beaten by their deranged classmate.
** The French release of the VisualNovel is for kids age 7+ [[http://www.pegi.info/en/index/global_id/505/?searchString=le+sanglot+des+cigales&agecategories=&genre=&organisations=1855&platforms=&countries=&submit=Search Don't believe it?]] [[note]]It's actually rated as a ''book'' and not as a game, so the ratings are much more loose.[[/note]]
* ''Anime/KeyTheMetalIdol'''s premise is about an android girl who wants to become human by making 30,000 friends. That sounds like something the kids can watch, right? WRONG. The series gets off to a family friendly start, then rapidly shifts into dark territory. Try not to not to get attached to any of the characters, since AnyoneCanDie. In fact, it borders on KillEmAll. And you don't even want to know about [[NightmareFuelStationAttendant Ajo]].
* ''LightNovel/KinosJourney'': Oh look, a teenager traveling around with a talking motorcycle with cute character designs! Too bad it's full of some fairly unsettling material, to said nothing about the [[TearJerker sometimes depressing]] ending of some of the episodes. [[spoiler: [[CruelTwistEnding Particularly the final episode]] of the anime]].
* ''Manga/KumaMikoGirlMeetsBear'' certainly looks and sounds wholesome from its description and artwork. Any viewer would be under this impression...until they got to the second half of the first episode, which proudly revolves around young children learning about bestiality.
* ''LightNovel/HaruhiSuzumiya's'' original novel is on the Accelerated Reading list for '''fifth graders'''. And one of the questions was about how Haruhi got possession of one of the computer club's computers.
* ''Anime/{{Monster}}'' has an in-universe example using a FracturedFairyTale or two. Those stories are such that most people would be seriously disturbed before a certain age if they were actually in print.
* ''Anime/NadiaTheSecretOfBlueWater'' seems family friendly enough at first glance, and, for the most part, it is. Yet there are many scenes, as well as several episodes, that are decidedly dark. Several characters are executed on screen, a family and their dog are gunned down, the heroine [[DrivenToSuicide tries to commit suicide]] at one point, and later, guns down [[spoiler:her own father, Nemo]] whilst [[BrainwashedAndCrazy under Gargoyle's control]]. There's even a brief instance of racism. Creator/ADVFilms themselves made this mistake when they were early on in the series, putting promotions for it on the same tape as ''Anime/SonicTheHedgehogTheMovie''. So a bunch of 8-year-olds who love Franchise/SonicTheHedgehog would be convinced to watch a show with all the aforementioned lovely bloody deaths.
* ''Manga/{{Narutaru}}''. Amusingly enough, one review actually described ''Manga/{{Narutaru}}'' as being acceptable for preteens. A scanlation group that re-released the Creator/{{Dark Horse|Comics}} translations of the manga and finished up what Dark Horse didn't get around to before discontinuing it made fun of this in their summary and updates. Just goes to show how [[CoversAlwaysLie bloody deceptive]] that first volume is...
** Glenat's French release of ''Manga/{{Narutaru}}'' was cancelled after two volumes under similar circumstances. Once they finally tried again, the series was given their Seinen label [[TaughtByExperience in order to avoid another fiasco]].
** The anime's deceptively cutesy opening depicts many horrors in a family friendly way, but first-time viewers wouldn't know that. The show was originally broadcast on ''Kids Station''.
* ''Manga/NausicaaOfTheValleyOfTheWind'' also qualifies, particularly its original manga. In addition to the melting God Warrior, Ohmu stampede, and a goodly dose of violence, the manga shows people blown or chopped to bits left and right. Oh, and some freaky psychic stuff.
* The film ''Anime/NightOnTheGalacticRailroad'' is often lambasted by people who pick it up for the cute [[FunnyAnimal anthropomorphic cat characters]] and unfamiliar with the original 1927 novel. Though the film does have its bright spots, it has a pondering pace and covers themes such as [[AdultFear existential despair, loss of childhood innocence through doubt in one's parents, and the afterlife]]. Did we mention the drowning children?
* Surrounding ''Anime/NinjaScroll'' is [[http://www.actsofgord.com/Chronicles/chapter12.php a particular story]] from Website/ActsOfGord about a man who rented the infamously gory anime movie with explicit rape for his ten- and eleven-year-old kids, all whilst Gord himself tries to tell him that it's ''really'' not appropriate for his kids. Of course, not more than one hour later does the same man barge in demanding to know why he gave them porn.
* ''Anime/NowAndThenHereAndThere''. {{Animation|AgeGhetto}}? Check. [[SarcasmMode Kooky]] [[TrappedInAnotherWorld fantasy adventure?]] Check. [[KidHero Child protagonist?]] Check. [[ApocalypseHow Desolate, dying world]], [[FamilyUnfriendlyViolence horrific]] [[AnyoneCanDie brutality]] and [[TheCaligula a king who makes]] ''ComicBook/TheJoker'' look at most mildly deranged? Check, check, oh God check.
* ''Webcomic/OnePunchMan'' seems to be innocent (it's a comedy {{superhero}} series about a the struggles of a InvincibleHero), but the manga version is considered a {{seinen}} for good reason. It has plenty of intense violence, as most of Saitama's foes end up as bloody messes. There is also a fair bunch of sexual humor, what with the hero [[ManlyGay Puri-Puri Prisoner]], and his love of other male heroes.
* Creator/OsamuTezuka developed his characteristic cartoony style drawing manga for younger kids, but maintained it well into his later career when he started drawing more mature manga like ''Manga/{{Adolf}}'' (a story about WWII, told mainly from the perspective of characters from the doomed Axis nations) and ''MW'' (a tale of a Catholic Priest who is tormented with guilt because he has a gay lover who is also a murdering sociopath planning to commit genocide with a stolen American chemical weapon).
* ''Anime/OsomatsuSan'' is based on ''Manga/OsomatsuKun'', a classic kid-friendly {{shonen}} manga, but has plenty of sex jokes and other adult material. It airs late at night as a result, with the manga adaptation considered a {{josei}}. However, it keeps ''-Kun'''s cartoonish, ''Anime/{{Doraemon}}''-like art. This had caused controversy in Japan, with a [[http://www.animenewsnetwork.com/interest/2016-02-09/bpo-publishes-viewer-complaint-about-man-catching-brother-masturbating-in-anime/.98499 masturbation joke]] attracting complaints.
* ''Anime/OutlawStar'' is a {{Seinen}} anime with graphic violence and an explicit HotSpringsEpisode... and yet it aired in America on Creator/{{Toonami}} at a timeslot where many kids under 13 would be watching. It should be noted that the episode underwent many edits, such as changing [[FamilyFriendlyFirearms guns into blasters]] and cutting swears, as well as excising the HotSpringsEpisode entirely.
* ''Anime/PantyAndStockingWithGarterbelt''. "Look, dear! There's two girls in pretty dresses fighting ghosts and other nasty bad things! Why haven't you shown this to your younger cousin?" Though the title alone should alert people, despite ''WesternAnimation/ThePowerpuffGirls''-esque character design. Funimation's complete set release has a TV-MA rating on its cover, leaving no question to what kind of subject matter this series has.
* ''Anime/PrincessMononoke'' certainly qualifies for this trope. It's an animated movie featuring pigs and wolves and nice-looking forest spirits, with [[EverythingsBetterWithPrincesses "Princess"]] in the title, but it's also a movie that shows people's heads and limbs being shot off, open wounds bleeding profusely, and {{Eldritch Abomination}}s covered in icky purplish wormlike things. Disney released their dub under their Miramax label, perhaps so people wouldn't confuse it with its own kid-friendly productions. Many parents brought young children to see the film anyway, especially as ''Anime/PokemonTheFirstMovie'' arrived in theaters around the same time.
* ''Anime/PuellaMagiMadokaMagica''. It's a genre [[MagicalGirl commonly for pre-teen girls]]. The character design is PuniPlush. One Swedish seller classified the series as "For all ages", Crackle.com rates it as TV-PG. and The Japan movie rating system classifies both Madoka movies as "Suitable for all ages"... NOT! The story is all about the characters being pushed beyond the DespairEventHorizon and one of them gets eaten alive.
** Speaking of the movies, a review on Common Sense Media of the series claimed that the friend of the user who wrote the review went to see the first Madoka Magica movie in a Canadian movie theater and saw a lot of toddlers at the showing. When Mami blew up the witch barrier during the part of the film based on the first episode, many toddlers got frightened and had to leave.
** Creator/TheABC ([[NamesTheSame in Australia, not the USA]]) has aired it multiple times, on a children's channel (but relatively late at night, on an anime block aimed towards young teenagers) with minimal censorship (only profanity censored). Either someone didn't do their research, or this [[AwesomeAussie says something about the resilience of Australian kids]]. There were no complaints from parents. Also, they got away with airing ''Manga/VampireKnight'' and ''Manga/OuranHighSchoolHostClub'' on that same channel without any problems.
*** In Australia, that series is rated as M (Mature), in which still in the unrestricted category unlike in MA15+. So Australians might be aware of the mature themes of the series as well.
* ''Anime/QueensBlade'' initially appeared through Netflix streaming in the Fall of 2010 with a '''Y7 FV''' rating. Yes, that implies the series is suitable for children age 7 or higher, but has a cautionary rating for "fantasy violence". By the end of the first volume, the viewer will have seen nipples that swell and spew a corrosive fluid, a disrobed woman wetting herself, and one scene of virtual lesbian rape.
** The front cover for the first volume of the series has four relatively attractive characters in standard "Sword and Sorcery" poses, but nothing to clue the viewer into what the series involves. Needless to say, the online reviews for the series quickly swelled with the reactions of angry parents.
* ''Anime/ReadOrDie'''s {{OVA}} (ignoring the title) seems like a delightful children's story. It's about a happy and sweet woman who loves to read and has amazing adventures! It's actually a pastiche of spy films in the 'Film/JamesBond'' vein with more HighPressureBlood.
* ''Anime/CrayonShinChan''. Despite the cute looks, the manga was originally published in Weekly Manga Action, one {{Seinen}} magazine.
** Also, the show has been dubbed and censored in most countries to kids' show standards (meaning no ass-dancing from Shin, and no crude jokes from anyone else), but in America, it's an Creator/AdultSwim show and the [[CrossesTheLineTwice dialogue is crammed with]] BlackComedy.
** In Indonesia, the original manga is dutifully labeled 'mature'. The animated adaptation however, is aired on weekends on a local TV channel, and it has been that way for more than 10 years. Nowadays most people ignore the warning label at the corner of the cover and it's considered a children's classic almost on par with ''Doraemon'' (which airs alongside ''Shin-chan'' on that same TV channel).
* ''Manga/SchoolLive'' looks like a sweet anime about an adorable group of teenagers and their precocious dog. Perfect show for your children to watch, right? [[spoiler:Wrong. At the end of the first episode, it's revealed that their happy life at school is a carefully constructed delusion to let Yuki cope with the zombie apocalypse. Prepare for things to get very dark, VERY quickly.]] The manga is even worse [[spoiler:as it contains more graphic gore and a lot of mental breakdowns.]]
* ''Anime/SelectorInfectedWIXOSS'' has been mislabeled by some as a shoujo meant to sell cards to young girls. While there is a tie-in game to the series, it's actually a late-night anime, with all the manga spinoffs running in seinen magazines. And understandably so, considering there's an incest plot with one of the main characters as well as one villain who basically [[MindRape mind-rapes]] her opponents.
* ''Anime/SuperMilkChan'' has an adorable cartoony art style and is about a five year old superhero. It's perfect for kids, it must be just like WesternAnimation/ThePowerpuffGirls, right? Wrong! God help anyone who decides to show their kids the GagDub...
* In America, ''Manga/WanderingSon'' has won at least one adolescent-geared award and is commonly spoken of when referring to teens. The series is considered relatable to transgender youth and it's not particularly graphic but it's not a shojo or even josei, but a seinen.
* The Canadian province of Quebec's movie and video ratings board had some problems with this in the early years of anime videos, with titles such as ''Anime/{{Genocyber}}'', ''Anime/NinjaScroll'' and ''Manga/{{Akira}}'' getting the equivalent of G and PG ratings. Fortunately, actual {{hentai}} never fell through the cracks, and the board wised up relatively fast.
* During TheNineties, the major TV networks in Mexico thought it would be good to syndicate something new instead of these American cartoons. So, they looked at Japan as a new, unexplored source of kids' cartoons, and they decided to broadcast anime, [[GermansLoveDavidHasselhoff thus starting the long-remembered Nineties' Anime Craze]]. Only problem is, they mostly took shows for teenagers and adults and marketed them for kids. The new Animax channel tried to return to a kid-friendly schedule, but NetworkDecay kicked in and the few animated features remaining are often... not for kids.
* ''Anime/FullMetalPanicFumoffu'' is a light-hearted comedy with a TV-PG rating on both the ADV Films and Creator/{{FUNimation}} [=DVDs=], and the adorable Fumoffu... completely kid-friendly, right? Let's see: gratuitous swearing (the word "shit" in the very first episode), an episode revolving around a sex offender, another episode revolving around a hot springs where full-frontal female and male nudity is seen (including one character running face-first into Sōsuke's junk), and two characters almost have sex in the final episode.
* Name almost any SchoolgirlSeries[=/=]{{Iyashikei}} SliceOfLife anime or manga. You may think that ''Manga/KOn'', ''Manga/{{Sketchbook}}'', ''Manga/KiniroMosaic'', and ''Manga/HidamariSketch'' are meant for [[{{Shoujo}} young girls and teenagers]] when in reality the targeted audience is meant [[{{Seinen}} for a much older demographic of the opposite sex]].
** The reason most SchoolgirlSeries[=/=]{{Iyashikei}} SliceOfLife anime and manga are meant for adult males is mainly because in addition to the blatant use of {{Moe}}, as well as the fact that they're designed as escapism from tediousness and lack of prospects and letting them experience the children they never had [[note]]Japan has one of the most minuscule birth rates in the world, and is gradually decreasing[[/note]], and an occasional TokenMiniMoe character, many of them have a lot GirlsLove subtext and many of the girl to girl relationships are portrayed realistically with CharacterDevelopment (the lesbian subtext definitely makes a ringing bell that these kind of series are ''not'' meant for little girls). Thus being said, most of the GirlsLove relationships are often portrayed as platonic (read, non-sexual).
* ''Anime/SummerWars'' got a '''PG''' rating from the MPAA and a TV-PG rating from Funimation. Obviously the MPAA must have been drunk or stoned when rating it, because it has instances of blood, [[spoiler:tragic death of a family member]] (but then again, there are several childrens' movies that have dealed with that concept), swearing, child nudity, a doomsday scenario, and so much more, plus that it's actually {{Seinen}}, meaning that it's targeted for adult males as opposed to the age demographic the PG rating is assigned to.
** Also in a notable case of ValuesDissonance, it meanwhile seems utterly bizarre to most Europeans who watch the film that it is rated 12 by the British Board of Film Classification and FSK in the UK and Germany, respectively, as nothing about it strikes your typical European viewer as being especially unsuitable for young children.
** Averted in its {{Creator/Toonami}} airing, as it was rated TV-14 for realistic violence and language.
* ''Anime/TenchiMuyo'', is, as of this writing, listed as an anime suitable for children/all ages in both a children's magazine website and About.com. Several ratings boards also passed the show G or PG in the beginning, and the original OVA series does start out tame. A lot of people have memories of the old Toonami version and likely think the show is just fine for kids, but the more readily-available uncut version today...not so much, to the point where it earned a "TV-MA" on a recent rerelease. To jog your memory, OVA 4 has [[spoiler:Ryouko showing her naked body off to Tenchi throughout, with Barbie doll anatomy averted]], and The Night Before the Carnival special has [[spoiler:Washuu demanding a semen sample from Tenchi - and offering to ''use her mouth'' to help!]]
* EzyDvd Australia lists everything animated as a children's series, which makes the "new children's [=DVDs=]" category as of January 2, 2014 full of MA15+ and sometimes even R18+ anime like ''Anime/WeWithoutWings'', ''Manga/QueensBlade'', ''Manga/MakenKi'', ''Manga/{{Monster}}'', ''Anime/FateZero'', ''LightNovel/IsThisAZombie'', ''LightNovel/BludgeoningAngelDokuroChan'', ''Manga/FutureDiary'', and ''Anime/ErgoProxy''.
* ''Manga/DFrag'' is a comedy series that pretty much parodies every highschool anime cliche you can think of. You think this is something a {{shonen}} audience who are into highschool comedies that would enjoy, right? Apparently, this series runs in a {{seinen}} magazine.
* Despite the cutsie covers and the fact that it was by the creators of ''Manga/CardCaptorSakura'', ''Manga/{{Chobits}}'' is fairly risque and has a decent amount of nudity. Barnes and Noble even put a "Not appropriate for children" label right above the Buy button on [[http://www.barnesandnoble.com/w/chobits-omnibus-book-1-clamp/1028422723?ean=9781595824516 the listings for both the omnibus collections on their website.]]
* A very, ''very'' good example is the anime (and visual novel) ''VisualNovel/SchoolDays''. Looks like a cutesy, cheesy romcom. Is reality usually much closer to a mature-ish romance (sex scenes and all) at best, or a demented slasher film at worst.
* ''Manga/WarauSalesman'' and ''Nosutaru Grandfather'' are created by Creator/FujikoFujio who has written many manga and anime shows for children, their most popular work was ''Anime/{{Doraemon}}''. Yeah, except for ''Warau Salesman'' and ''Nosutaru Grandfather'', both are horror manga that has nudity and blood and gore. For good reason, they are considered a {{seinen}}. Also, both are only Fujiko Fujio works that are created for adult audience.
