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. 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 ]]

* ''IMyMeStrawberryEggs''
* ''TenshiNaKonamaiki'' has both a ''chikan'' episode and a ''sekuhara'' (sexual harassment) episode.
* ''ChouKuseNiNarisou''
* ''Manga/KimagureOrangeRoad'': In a manga episode, [[TheHero Kyosuke]] is distressed because LoveInterest {{Tsundere}} 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 [[TooDumbToLive 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.
* ''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.
* Futana from ''Manga/FutabaKunChange'', much to the dismay of [[GenderBender "her"]] brother.
* 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.]]
* Nanoka runs into a chikan on her way to school during an episode of ''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.
* In the ''LoveHina'' 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 LoveHina 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...
* A whole episode of ''TanteiGakuenQ'' 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 ''YoureUnderArrest'', the WholesomeCrossdresser Aoi Futaba is actually part of the Anti-Chikan unit.
* ''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 one chapter of the ''KeroroGunsou'' 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!"
* Hilariously done when [[JerkJock Agon]] and [[MagnificentBastard Hiruma]] save a girl from one of these in ''{{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 ''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.
** Briefly referenced to in ''WanderingSon'', by the same mangaka. 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.
** 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, and Yuki from ''WanderingSon'' gets groped by a man on the train but then becomes his friend in a spinoff.
* 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."\\
* In the ''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.]]
* In an episode of ''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/DeathNote'', Mikami sets one up to die so he can confuse the SPK with a fake notebook.
* 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.
* 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.
* A short one in ''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.
* 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.
* This issue is only referenced, never explained in 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]].
* 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.
* In an early chapter of ''Manga/DetroitMetalCity'' Negishi is falsely accused of subway groping. It later also turns out that Gaylord ([[spoiler:the first Krauser]]) had to temporarily retire from metal because he was jailed for sexual assault after groping women on trains.
* In ''DetectiveConan'', [[{{Bifauxnen}} Masumi Sera]] was believed to a chikan who molested Sonoko during her introduction, so Ran attacked her. Fortunately, Sera could defended 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 didnt 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.]]
* 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.
* 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.
* 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.


[[folder: Comic Books ]]

* 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.


[[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.]]


[[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 ''{{Reno 911}}'', but since the "bait" is Dep. Weigel no one tries it.
* An incident with a tv reporter who had her bottom pinched while in the [[http://www.youtube.com/watch?v=E3f6WMSXQNg middle of a live report]].


[[folder: Webcomics ]]

* Erika from ''Webcomic/MegaTokyo'' runs into one and handles it [[http://www.megatokyo.com/strip/125 in her usual manner]]
** 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}}
-->"Leave the limbs you've lost. They belong to me now."


[[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.]]''

* ''TheOnion'' once ran an opinion piece in which a frotteur complained, [[{{Squick}} in great detail]], about how difficult this was becoming.
* Not just TruthInTelevision in Japan - the [[UsefulNotes/TheT MBTA]] (Boston public transit) police have actually issued a warning about this problem.
