Japanese public transit is ''very'' crowded -- in fact, the operating companies hire employees to help pack trains as full as possible at the height of rush hour (often struggling young or retired sumo wrestlers who need extra cash). Japanese society has very strict sexual mores, as well. A significant social problem is that of creepy strangers on public transit (or in parks) anonymously fondling women in the midst of the crowd and confusion, or otherwise molesting them. These molesters are known by some anime fans as ''chikan'' (''chikan'' is actually the '''act''' of sexual assault by groping, not the perpetrator), and signs are prominently posted in parks and on transit warning women about them. The (much rarer) females who engage in this behaviour are called ''chijo''.

As of 2006, the Japanese subways have addressed this problem by establishing women-only cars on every train. These are reportedly ''quite'' popular[[note]]But it also created a bit of a backlash, as women who did not use (or missed) the women-only cars were assumed to be asking for it.[[/note]]. However, their failure to put a dent in numbers of cases resulted in the introduction of routine undercover police patrols of subways in 2009, coupled with new awareness campaigns to encourage reporting and prosecution of offenders.

This problem, incidentally, is also common in other crowded countries with traditionally very patriarchal cultures: India, Indonesia, Taiwan, Egypt, Brazil, and Mexico have, inspired by Japan, all started designating certain passenger cars in their public transport networks (subways, commuter railways, and even bus lines) as women-only for basically the same reason.

Many anime and manga series have at least one episode where a female character encounters a ''chikan'' who must be confronted or evaded. The Chikan will tend to be a one-shot character serving a similar role to the MonsterOfTheWeek. It's rare for a series to have a recurring ''chikan'', although quite a few series have perverted characters, many of whom are even portrayed sympathetically.

Chikan can also be considered a specific genre of pornography, particularly in Japan where the plot of doujins, hentai, films, etc. can be centered around the issue.



[[folder: Anime & Manga ]]
* Shimura seems to have a thing for Chikan in her manga:
** In one of her earlier manga ''Inhabitants of the Threshold'' the protagonist - who was a boy - gets molested by a man on the bus.
** In ''Manga/AoiHana'', the characters meet again after Fumi is molested on the train. Akira stomps on the Chikan's foot after she recognizes Fumi's expression and advises she remember to do that in the future.
** ''Manga/WanderingSon'':
*** Briefly referenced to. Once beginning high school, Chiba began going on the train. She says she encountered a pervert, but nothing much is said about it. Starting from then, she lets her mom drive her to school.
*** In an unrelated manga anthology, Yuki had a chapter about her. She gets groped by a man on the train but they end up making small talk.
* ''Boku To Boku'' starts when a [[{{bifauxnen}} tomboyish]] girl points out a chikan on the train who is touching a middle school girl. The two talk later and she quickly [[UnsettlingGenderReveal learn]] that the "girl" is a WholesomeCrossdresser.
* In ''Manga/{{Change 123}}'' Motoko is molested by a chikan on the way to meet Kosukegawa. She is so flustered that her SplitPersonality [[BloodKnight Hibiki]] takes control and reaches down to meet the pervert's fingers. At first he believes she is getting into it, but needless to say this was not the case.
-->"Woah! All four of his fingers are backwards."\\
* ''Manga/CheekyAngel'' has both a ''chikan'' episode and a ''sekuhara'' (sexual harassment) episode.
%%* ''ChouKuseNiNarisou''
* In ''Manga/DeathNote'', Mikami sets one up to die so he can confuse the SPK with a fake notebook.
* A short one in ''Manga/DeepLove'' where a man molests Ayu on a train, she lets him and robs him afterwards (charging the amount she would for regular johns). She throws the money away afterwards.
* ''Manga/DetectiveConan'':
** [[{{Bifauxnen}} Masumi Sera]] was believed to a chikan who molested Sonoko during her introduction, so Ran attacked her. Fortunately, Sera could defend herself. Conan pointed out that Sera grabbed the hand of the actual chikan and Sonoko mistook the wrong one for the culprit. Of course, they didn't know that [[GenderReveal Sera was a girl]] when they first met her.
** A character called Etsutoshi Oba crossed his arms in the train, so nobody would mistake him as a chikan. [[spoiler:It turns out that he crossed his arms to hide the knife which he used to kill the hooligan who killed his twin brother.]]
* A whole episode of ''Manga/DetectiveSchoolQ'' focuses on three detective girls (TheChick Megumi, ActionGirl Yukihira and former {{Meganekko}}/now CuteBruiser-in-training Kuniko) trying to capture one of these who attacked Kuniko on a train. Kuniko had just gone through a tremendous BreakTheCutie ordeal few weeks ago and, despite her AdrenalineMakeover, she still had a long way to go, and ended up [[HeroicBSOD having a sobbing meltdown]]. Yukihira also gave her a quick GetAHoldOfYourselfMan, letting her pull her act together, which she did as the three girls worked together to locate the offender ''and'' prove his involvement. [[spoiler: By the end not only they succeed, but Kuniko partially upgrades to ActionGirl by being the one who knocked out the chikan in the end.]]
* In an early chapter of ''Manga/DetroitMetalCity'' Negishi is falsely accused of subway groping. It later also turns out that the temporary absence from the music scene of Gaylord ([[spoiler:the first Lord Krauser]]) was because he was jailed for sexual assault after groping women on trains.
* ''Manga/EdenNoHana'' features one that tries to grope Midori Wakatsuki's thigh when she [[SleepyHead falls asleep]] on her train seat. Her classmate Hashiba realises this just in time, and scares him off.
* Futana from ''Manga/FutabaKunChange'', much to the dismay of [[GenderBender "her"]] brother.
* Hilariously done when [[JerkJock Agon]] and [[MagnificentBastard Hiruma]] save a girl from one of these in ''Manga/{{Eyeshield 21}}''. After being sent a live video feed of said girl being harassed by a chikan, Agon immediately leaves where he is, goes to the subway, and ''rips the man from the train while it's moving.'' Agon then gets to work on getting under the girl's skirt while Hiruma goes on to blackmail the chikan.
* In ''Manga/GirlFriends'', Sugi encounters one during her ADayInTheLimelight chapter, who happens to be [[spoiler:her elementary school teacher]]. This is also something of a subversion because she's actually ''used'' to dealing with molesters; it's the salarymen who come to her rescue that she worries about because they inevitably want to date her.
* ''Manga/GreatTeacherOnizuka'': In a rare case of the ''chikan'' being a regular character, our hero pounds one on the bus in an early episode, only to find out later that the molester is his new boss, Vice-Principal Hiroshi Uchiyamada. Uchiyamada eventually ends up landing in serious hot water when he's caught by an undercover policewoman, leaving his things in the train when he flees in a panic. Naturally, Onizuka finds it, and fearing blackmail, Uchiyamada decides to not go forward in his latest "get Onizuka fired" plot. The irony of the first situation is that ''Onizuka'' himself wanted to do it, but Uchiyamada got there first.
%%* ''IMyMeStrawberryEggs''
* ''Kanojo Ni Naritai'' starts with the protagonist getting felt up by a man while riding to school and is too nervous to do anything. Luckily a girl - his crush surprisingly - rescues him.
* In one chapter of the ''Manga/SgtFrog'' manga, mom Aki ends up fending off a ''chikan'' with a judo throw while ruminating on what makes an appealing manga character. She then tells him "If you want to feel up ''this'' [[MediumAwareness manga character]], come up with a better scenario first!"
* ''Manga/KimagureOrangeRoad'': In a manga episode, [[TheHero Kyosuke]] is distressed because [[LoveInterest Madoka]] is mad with him, and his cousin Kazuya advices him acting pervert towards Madoka to get her to forgive him. [[IdiotHero Too dumb to acknowledge an obvious plot to get back on him]], Kyosuke falls for it and he decides fondling Madoka in the subway... but before he makes the attempt, another woman gets fondled near from them and angrily confronts her harasser. Madoka states how much she detests that kind of men, and Kyosuke wisely loses his nerve and realizes apologizing Madoka is the right action to earn her forgiveness.
* Nanoka runs into a chikan on her way to school during an episode of ''Manga/KoiKaze''. It's not a major plot point, but it occurs shortly after Nanoka got into an argument with her older brother Koshiro because she felt he was being annoyingly overprotective of her, and the experience led her to appreciate that Koshiro meant well.
* ''Manga/LoveHina'':
** In the Christmas Special, Motoko is groped by one on a subway; her response, being Motoko, is violence. But unlike the vast majority of violence she was able to inflict in ''Love Hina'' to that point, this time, [[RealityEnsues her beating the man almost gets her arrested.]]
** Also happens by accident to Naru and Keitaro. Poor guy just never gets a break...
* Inverted in ''Manga/MahouSenseiNegima'' in the first chapter when Negi is riding to the school. Little boys are QUITE popular with high school age girls. And that sequence was ''significantly'' less perverted in the original than it was in the Del Rey version...
* An episode of ''Manga/MaicchinguMachikoSensei'' feauture a man harrass the young female student on a bus. Initially the DirtyKid Kenta is mistaken for the culprit, but Machiko and Kenta set a trap for catching the real culprit.
* In ''Anime/MawaruPenguindrum'', Ringo's friend Yukina mistakes Shouma for one. Meanwhile, #1 is prone to squeeze into skirts and has mastered the Floor-Level Mirror Technique.
* In the ''Manga/MidoriDays'' manga, several girls in Ayase's class get their skirt slit by a pervert on the subway. Ayase's response is to dress Seiji in drag and have him accompany her on the train. Naturally, [[AttractiveBentGender his (uninformed) male friends think him the hottest thing ever]]. He catches the pervert ripping [[{{Tsundere}} Ayase's]] dress and proceeds to beat the crap out of him, only [[ClothingDamage partially losing his disguise]] in the process. [[AccidentalPervert And accidentally ripping off Ayase's skirt.]]
* ''Manga/MyLoveStory'' begins when Takeo sees a man trying to grope a girl on the train and confronts him. It's LoveAtFirstSight for Takeo and the girl, his future girlfriend Yamato. The man tries to victim blame Yamato for wearing a short skirt (her school uniform) but Takeo punches him.
* In ''Manga/NoMatterHowILookAtItItsYouGuysFaultImNotPopular'', this was the focus of chapter 24 aptly titled, "Because I'm not popular, I'm going to get molested". In the chapter, Tomoko hears one of her classmates complain about how she was molested on her way to school and laments that no one wants to molest her. [[spoiler:Eventually, she does get molested only to find out that her "molester" was in fact a large staff.]]
* In ''Manga/OtomeNoTeikoku'', Ayano encounters one on the train ride to school, and unlike most things in the manga that deal with sex, this is ''not'' played for titillation. While we don't see the attack, we do see the usually cool Ayano hesitant to leave school and when [[RomanticTwoGirlFriendship her best friend, Miyoshi]] demands to know whats wrong, Ayano breaks down crying saying how scared she was.
* In an early story in ''Manga/{{Parasyte}}'', an alien possessing the body of a female schoolteacher catches a chikan groping a different woman, while commuting home. She loudly calls him out on it, and eventually beats him senseless. The other passengers, meanwhile, cheer her on.
* Parodied in an episode and chapter of ''Manga/SayonaraZetsubouSensei''. Nozomu is shown handcuffing himself to the train railing to prevent accusations of this, but when Nami screams out for an unrelated reason, he gets arrested anyway. When Nami explains he wasn't molesting her, the police are happy to let him go, but Nozomu wants to plead guilty--his logic is to the effect that being punished means he can move on afterward, but if he denies it, people will think he's scum.
* This issue is only referenced, never explained in ''Manga/SeitokaiYakuindomo''. In episode one, main character Takatoshi finds himself in a subway car nearly exclusively populated by women. To keep from being falsely accused, he assumes the same position as all the other men: riding with his hands held high so that no one can call him a molester. It's a social issue that's played for laughs, [[GagSeries like most other things in the series]].
* Subverted in ''LightNovel/{{Shimoneta}}'', where the girl falsely accuses a guy of groping her on the railway for the reward money she'd get for turning him in under the setting's Orwellian obscenity laws. The main character has to rescue the guy by claiming that ''he'' did it and then trying to run away.
* In an episode of ''Anime/SpeedGrapher'', a guy grabs Kagura's ass on a subway, however, since Kagura is a sheltered rich girl who knows very little about the real world and has never even been on the subway before, she doesn't do anything about it and just giggles and blushes. A bit later when Saiga asks what she was giggling about, she tells him a guy was "tickling" her; Saiga tells her the guy was a pervert and she should have told him about it sooner.
* In ''Manga/StrawberryOneHundredPercent'' Mukai is harassed on a bus from one of this; Manaka intervenes interposing between them. Manaka himself is mistaken for a chikan by Amachi while he and Aya find themselves too close on a bus.
* The ''Manga/TokyoGhoul'' one-shot ''Joker'', Juuzou and his partner witness one molesting a girl on the train and call him out. Shortly afterwards, they come across the pervert being attacked by the Ghoul they've been hunting. It turns out to be the girl they rescued, who followed and ripped the offending arm off in revenge.
* ''Manga/UltraManiac'' had Ayu get prodded by a boy when travelling to school one morning, Nina makes her a magical ring to stop perverts touching Ayu in future. It is supposed to give them non-lethal but still pretty painful electric shocks when they touch Ayu at all, unfortunately it classifies anyone male as a potential groper.
* In ''Manga/YoureUnderArrest'', the {{transsexual}} Aoi Futaba is actually part of the Anti-Chikan unit. She began dressing as a woman specifically to catch these type of people.
* One {{hentai}} subverted the usual expectation for its genre with regards to this trope. The woman in question (the heroine) pinched the offending hand with her hairclip and disembarked.

[[folder: Comic Books]]
* An issue of ComicBook/PowerGirl featured a pervert who groped her in a subway. Bad idea..
* Music/{{Voltaire}}'s comic, Deady Big in Japan mentions this when Deady is shoved into a subway. He turns out to be the Chikan. (Since he has tentacles, he is able to harass a great deal of women at once) The women he is harassing then accuse an elderly man of touching them and beat him up. Deady walks away unscathed.
* Issue 51 of ''ComicBook/Gen13'' has Fairchild riding a train with a crowd of men around that don't miss the chance to rub against her using the train's exit as excuse.

[[folder: Fan Fiction]]
* Kasumi is a victim of one in the ''VideoGame/DeadOrAlive'' fic ''FanFic/KunoichisLikeUs''. She promptly [[MuggingTheMonster lays him out flat]], to the crowd's acclaim.

[[folder: Film]]
* In ''Film/TokyoGorePolice'', when the heroine, disguised as a prostitute, is groped by a chikan on the subway, she reacts by [[EveryJapaneseSwordIsAKatana cutting off]] [[AnArmAndALeg his hands.]]
* In the Spanish movie "The Holy Girl", the new teacher in town introduces himself to the holy girl by stepping up behind her in a crowd to frot.
* In ''Film/TheSweetestThing'', Christina's a RareFemaleExample. She [[NoGuyWantsToBeChased goes up to meet Peter and introduces herself]] to him by grabbing his butt.
* Mistress Lisa in ''Literature/ExitToEden'' admits to Citizen Elliot that she's a chijo during [[KinkySpanking his spanking]]:
--> I like butts. Men's beautiful behinds. You know what I like to do to gorgeous butts? I like to squeeze them, pinch them and caress them.
* ''Film/KinjiteForbiddenSubjects'': Two Japanese businessmen discuss the subject after one of them witnesses a woman being groped on the subway who does not loudly protest, both regarding it as a form of sexual fetishism. Later one of them drunkenly attempts the same thing on a business trip in the United States, [[ValuesDissonance resulting in immediate retaliation]].

[[folder: Literature]]
* Western example: The main character in ''A Tree Grows in Brooklyn'' is groped on a train. Her aunt considers it a [[SheIsAllGrownUp sign of maturity.]] This particular aunt is a GoodBadGirl who ReallyGetsAround, and the story is set in the 1910s, so expect some ValuesDissonance to be in play. To be fair to the aunt, she gave her a knitting needle which the protagonist was almost looking forward to using.
* In the introductory Japanese textbook Genki, one of the [[HoYay male]] characters, Takeshi, is groped by a shadowy chikan in a cartoon illustration of the vocabulary world "sawararemashita" (to be touched against one's will).

[[folder: Live Action TV]]
* The story of ''[[Franchise/TrainMan Densha Otoko]]'' (''Train Man''), both in real life and the dramatized TV version, starts with a loser confronting a chikan on the subway and unexpectedly winning a date for his trouble.
* They try to set up a sting for this on ''Series/{{Reno 911}}'', but since the "bait" is Dep. Weigel no one tries it.

[[folder: Video Games]]
* Lei-Fang's ending in ''VideoGame/DeadOrAlive 4'' is a perfect example of ValuesDissonance. A man stumbles on a train and accidentally grabs Lei-Fang's breasts as he's falling. She responds by kicking him out of the train's windows, where he plummets into a river. The situation is PlayedForLaughs, and the crowd gets up and gives Lei-Fang a standing ovation. Find the video on Website/YouTube and read the comments to get an idea of how disturbing this is to Westerners... Though some of the commenters do seem to think it was DisproportionateRetribution (it's explicitly shown to be an accident on the man's part) and the guy may have been killed. Some of the applause was probably due to her shirt unbuttoning and her skirt slitting up to her pantyline.
* In ''[[VideoGame/{{Twinbee}} Twinbee Taisen Puzzle-Dama]]'', Madoka takes [[IneffectualSympatheticVillain Dr. Wa]][[ButtMonkey rumon]] as one upon encountering him in her storyline. [[CrowningMomentOfFunny The poor guy's response]] to this is ''[[http://www.youtube.com/watch?v=44_S143Uu10#t=2m04s priceless.]]''

** Later, Junko [[http://megatokyo.com/strip/773 accuses]] L33t Guy of being one.
* A ''Webcomic/SexyLosers'' strip (titled [[IncrediblyLamePun Chikan Fingers]]) features a chikan who runs into a not-so-wholesome crossdresser, who [[CrossesTheLineTwice threatens to scream if he stops]]. (And that's not even the punch line.)
* AxCrazy Banana Bazooka in ''Webcomic/GorgeousPrincessCreamyBeamy'' encounters two of these. In the next strip, they run off the train screaming, their arms severed at the shoulders, and she runs after them waving a {{BFS}}
