History YMMV / Inuyasha

** In North America, the series' EstrogenBrigade is much larger than its intended audience of [[ShonenDemographic teenage boys]], and is considered the most popular girls' anime, matched only by ''Franchise/SailorMoon''. The anime is particularly popular in Canada, as it and ''Anime/GundamWing'' helped kick off the airing of teen-oriented anime on the Creator/{{YTV}} network, not to mention that both shows feature Canadian dub casts from Creator/TheOceanGroup.

* InformedWrongness: Inuyasha, anytime Kikyo is brought up at ''all''. Anytime Inuyasha thinks about Kikyo, in terms of wondering about her plans against Naraku and the time when Naraku seemingly killed her with miasma and he wondered if she was alive or not, he is automatically treated as the one in the wrong by Kagome who gets unreasonably jealous, and also by Miroku and Sango who act as if he is being unfaithful to Kagome and must apologize to her, even though there were no romantic implications to his thoughts about Kikyo. Even though Kagome realizes her anger is unnecessary, it doesn't stop it from happening repeatedly in the manga. Though this is ignoring how Inuyasha will get ''twice'' as angry whenever Koga flirts with Kagome, despite Kagome making it clear to Inuyasha several times she's not interested in Koga, it does little to stop his jealousy. Suffice to say that neither of them are good at keeping jealous feelings at bay.

* CommonKnowledge: 'Sesshomaru raised/adopted Rin' pops up often in discussions of their characters, but while Rin does spend most of the series travelling with him, the time that covers is only about a year. The series actually ends [[spoiler: with Rin staying behind in a human village until she's old enough to decide whether she wants to remain in the human world or not; and it's ''Kaede'' who takes her in and raises her for the rest of her childhood, with Sesshomaru visiting her but not actually involved in her upbringing.]]

** Yura of the Demon Hair was in two early episodes as a random MonsterOfTheWeek and yet has a decent fanbase thanks to her [[EvilIsSexy alluring design]], unique hair-based powers that made her surprisingly dangerous, and her voice and personality that made her a SoftSpokenSadist who was pretty much {{Yandere}} for Inuyasha (or rather, his hair). This all made for a very fascinating and cool StarterVillain, so much so that some feel she ought to have been a recurring character.

* EstrogenBrigade: The series is primarily aimed at teenage boys since the manga ran in ''Shonen Sunday'', but it's also attracted a huge number of female fans due to the [[CastFullOfPrettyBoys many attractive male characters]] and the focus on the growing romance between Inuyasha and Kagome. This is [[GermansLoveDavidHasselhoff especially the case in North America]], where its female fanbase greatly outnumbers the male fans.

* WhatDoYouMeanItsForKids: The series was aimed at boys in upper elementary or junior/high school, Shonen Sunday's target demographic. In the United States, it had to air very late at night on Cartoon Network and be aimed at a college age audience. [[FullFrontalAssault The fact that a bare-breasted centipede demoness appear in the very first episode is something to say after all.]]

** In America the show's PeripheryDemographic is much larger than its intended audience, and is considered the most popular girls' anime, matched only by ''Franchise/SailorMoon''... despite being a {{Shonen}} show.
** ''Inuyasha'' is also very popular in Canada, as it and ''Anime/GundamWing'' helped kick off the airing of teen-oriented anime on the Creator/{{YTV}} network, not to mention that both shows feature Canadian dub casts from Creator/TheOceanGroup.
** This show is ''very'' popular in Vietnam as chances you would see comments from Vietnamese speakers are high in the internet, and to the point the OST is also used in Vietnamese media and films (though it probably doesn't include credit and permission however).

* SpiritualAdaptation: This is pretty much ''Literature/JourneyToTheWest'' but done as a Japanese period piece with its own folklore. Try think of Inuyasha being Sun Wukong, Kagome being Tripitaka, Shippo being Pigsy, and Miroku being Sandy.

** Shippo, considering that he's introduced as a capable magic user able to hold his own against Inuyasha, but is just [[{{Flanderization}} flanderized]] into being a BrattyHalfPint and TheLoad. Shippo's wasted potential is pretty prevalent in the video games where he is almost always a GameBreaker due to his speed and vast attacking abilities.

* EvilIsSexy:
** As already mentioned above, Yura of the Demon Hair was in two early episodes as a random MonsterOfTheWeek and yet she somehow gained plenty of fanboys thanks to her sexy voice and {{Stripperiffic}} outfit.
** Kagura is also pretty attractive for a demoness and gets ClothingDamage to the chest, twice! Although the anime has her breasts covered up during her ClothingDamage, the manga has no problem showing her breasts completely uncovered! Cue nosebleeding fanboys.
** Believe it or not, ''Naraku'' himself has plenty of fangirls, when he isn't shown with BodyHorror.
** Sesshomaru before his HeelFaceTurn.
** Toran, Karan, and Shunran of the Panther Deva quartet before their HeelFaceTurn.
** In fact, any normal looking evil demons are pretty sexy themselves.

* TrollingCreator: The filler episode, "Koga and Sesshomaru: A Dangerous Encounter", was basically this. The entire plot of the episode hinges on "What would happen if Koga and Sesshomaru met", a popular story idea among fans. The reasons being Koga's wolves killed Rin, Sesshomaru is Inuyasha's half-brother (whom they both hate), and Koga's natural antagonism towards dog demons. Ginta and Haku even go out of their way to keep the two from meeting. In the end, when they do meet, they hold no animosity for each other, though Koga is fully aware Shesshomaru is Inuyasha's brother but has nothing against him personally.

* JerkassWoobie: Kagura, Inuyasha. The former is forced by Naraku to do his whims and only can be free on death, all she wants is to be independent and free. The latter, has his mother dying at a young age, hunted down by both demons and zealot, demon hating humans from that young age, his own half brother despises him, a malicious BigBad forces his first love to betray each other and that's not even getting into the constant abuse from his allies, justified or not. It's no wonder he's abrasive to everyone.

* WhatMeasureIsANonBadass: Fans throwing a fit because Sango ''dared'' [[spoiler: to get married and have kids]], and calling Kagome "weak" because being physically weak somehow makes you a weak person overall, even though she was just a regular schoolgirl thrust in the feudal world and she STILL gets a lot stronger as time goes on. It's averted in the actual series: Sango is a feminine, YamatoNadeshiko family girl who is a demon slayer, and Kagura is a LadyOfWar that fights in a pretty kimono, her weapon is a pretty folding fan, and her attacks are all dances.

* CoveredUp: Of the TranslatedCoverVersion variety: Australian pop singer Sophie Monk's [[https://www.youtube.com/shared?ci=gP9cwMwh11U Come My Way]] was covered by Namie Amuro as "Come" and used as the 7th end theme. Try finding a video where it's not listed as "English cover".

** Kikyo and Kagome, either good foils to Inuyasha or incredibly bad influences on his behavior. Kagome being extremely clingy and getting jealous for any reason, even if it's not justified and Kikyo, who constantly avoids him and/or manipulates him into getting what she wants. Both their problems (going back to the present to graduate and finishing off Naraku when she's not capable) respectively have dragged down Inuyasha on more than one occasion.
*** [[https://twitter.com/HelenaWayneBlog/status/1279454784563675146 It apparently got so bad]] that it made Kagome's first English actress, Moneca Stori, not come back for ''The Final Act'' following her retirement. While Willow Johnson, Kikyo's actress, did reprise her role, she never expected the character to be so polarizing which made her give up voiceover in general for a while until ''Yashahime'' came along where she returned once more.

* MemeticMutation / NeverLiveItDown:

* CommonKnowledge: 'Sesshomaru raised/adopted Rin' pops up often in discussions of their characters, but while Rin does spend most of the series travelling with him, the time that covers is only about a year. As protective as Sesshomaru is towards her, both in and out of universe their relationship is described as a lord and his vassal/follower, rather than father and daughter. The series actually ends [[spoiler: with Rin staying behind in a human village until she's old enough to decide whether she wants to remain in the human world or not; and it's ''Kaede'' who takes her in and raises her for the rest of her childhood, with Sesshomaru visiting her but not actually involved in her upbringing.]]

** Anytime Sesshomaru insults Inuyasha for being a half-demon has become pretty ironic now Sesshomaru himself ends up having half-demon children in ''Yashahime''.

** Anytime Sesshomaru insults Inuyasha for being a half-demon has become harsher due to how Sesshomaru himself ends up having half-demon children in ''Yashahime''.

* HilariousInHindsight: During his first appearance, Sesshomaru makes the Nothing Woman take the form of Inuyasha's mother to extract the location of their father's grave from him. When Inuyasha claims he's not fooled since his mother is long-dead, Sesshomaru convinces him that he brought her soul back from the dead and gave her a new body, and Inuyasha seems to believe that such a thing actually is within his brother's power. It totally isn't, but later in the series when he gains mastery of Tenseiga, resurrecting the dead actually does become one of his trademark abilities.
** Anytime Sesshomaru insults Inuyasha for being a half-demon are now this due to how Sesshomaru himself ends up having half-demon children in ''Yashahime''.

** The press release for the upcoming sequel ''Yashahime'' reveals that Sesshomaru has half-demon daughters, leading fans to speculate on who the mother is. The possibility of Rin being the mother produced this reaction for some people.

** It's very easy to mistake Shippo for a girl at first, in both the manga and anime. His voice in Japanese and most dubs doesn't help, since he's mostly [[CrossDresssingVoices voiced by actual girls]].

* AlternateCharacterInterpretation:

** Any of the individual ships featuring Sesshomaru and Rin vs. Sesshomaru/Rin itself, especially towards the New Tens. With Sesshomaru/Rin being one of the bigger ships of the fandom, it was sure to catch some heat from fans who thought the relationship was WifeHusbandry in the making (mostly due to ValuesDissonance), and some who simply preferred them with other partners. Sesshomaru/Kikyo and Sesshomaru/Kagura were often used as alternatives for the former, and Kohaku/Rin for the latter. Sesshomaru-related ShipToShipCombat only intensified many years later when its [[SequelInAnotherMedium anime sequel]] ''Anime/YashahimePrincessHalfDemon'' revealed that Sesshomaru has [[SpinOffspring two half-demon daughters]] with no mother initially announced.
