History YMMV / Touhou

** Flandre, despite only appearing in a few games, is far more well known than her more prominent sister Remilia, who is pretty popular in her own right.

** [[Manga/TouhouBougetsushou Silent Sinner in Blue]] will always be known within the fandom as the infamous storyline that introduced The Watatsuki sisters, [[TheScrappy an unlikeable]] pair of [[FantasticRaciam Xenophopic]] InvincibleVillain. To make the matter worse, the narrative story even implied that Watatsuki sisters were '''not''' even in the wrong and they were within their rights to clap the main characters in a CurbstompBattle manner.

* AnticlimaxBoss: The TrueFinalBoss of ''Antinomy of Common Flower'' [[spoiler:The dream version of Tenshi Hinanawi who wanted to take over the world]] is a massive stepdown from the FinalBoss. Her spellcards are either really slow or just predictable.

** [[PortmanteauCoupleName MAlice]] Cannon in ''Imperishable Night''. Lasers in the earlier ''Touhou'' games were somewhat laggy in their hit detection. In ''IN''[='=]s case, this meant that you could switch between Alice and Marisa rapidly, and Alice's full damage would go through, the lag on the laser covering the time as Marisa. Interestingly, without this trick the Marisa/Alice team is woefully underpowered.

* MagnificentBitch: Okina Matara is the mastermind behind the [[VideoGame/TouhouTenkuushouHiddenStarInFourSeasons sixteenth game]]'s unusual flow of seasons, using her ability to pour energy into anything through their backs as a show of power [[AttentionWhore to remind everyone that she exists]], as well as to replace her unwitting servants. In ''[[Manga/TouhouSangetsusei Visionary Fairies in Shrine]]'', she turns a large number of fairies into stone cherries in order to draw out Hell's intentions, eventually getting a hold of one of their fairies and ordering the latter to come back to Hell's bigshots and tell of Okina's existence, effectively setting herself up as Gensokyo's deterrent against intruders. In ''[[VideoGame/HifuuNightmareDiaryVioletDetector Violet Detector]]'', she messes around with a human from the Outside World, Sumireko Usami, by splitting the latter's consciousness and body, then giving the body to a dream soul and convincing that soul that it's the real Sumireko; Okina only reveals the trick when the fake meets the real deal, and promptly strips the fake of its borrowed powers to make the duel fair. With the potential to remake Gensokyo from the ground up with her powers, Okina consistently makes her ends meet without ever truly giving away her entire hand, reinforcing Gensokyo's mysticism and safety from outside forces in the process.

** Practically overnight after the full version of ''Wily Beast and Weakest Creature'' was released, Saki Kurokoma became a ''literal'' Ensemble Darkhorse. Her explosive popularity is mostly attributed to her cowboy-inspired design; the sheer absurdity of a cowgirl Touhou made people doubt she was real at first, and tons of "howdy" and "yeehaw" related memes sprung up around her. Her cowgirl design also made her [[GermansLoveDavidHasselhoff very popular amongst]] [[AmericansAreCowboys Americans]].

** The general consensus is that ''Legacy of Lunatic Kingdom'' would be a much better game if Junko, the final boss, was better designed. All but a few of her attacks are variations on expanding danmaku rings, which, as several big-name ''Touhou'' players have pointed out, are the easiest and quickest danmaku patterns to program. Most of them require ''extremely'' tight micrododging, which makes playing as anyone but Reimu painfully difficult and leads to a lot of clipping deaths.

** Borderline case for ''Silent Sinner in Blue''. Mainly for introducing two characters who defeated popular characters in ways that can be best described as either DeusExMachina or outright cheating.

** Writing ''Touhou'' {{Doujin|shi}} where Marisa [[UsefulNotes/JapanesePronouns refers to herself with the masculine pronoun "ore"]] will immediately get you dismissed as a non-fan who's just using ''Touhou'' characters to get more sales. [[note]]While Marisa's speech pattern is rather blunt and boyish, she still uses the standard mildly-feminine pronoun ''watashi''.[[/note]]

** In a sense, this series is well liked by fans of [=YTPMV=] sources such as Advertising/TheManYourManCanSmellLike commercials with Creator/TerryCrews and Creator/JackBlack's appearance on ''Series/SesameStreet'' due to the series' music being popular sources to remix.

* Mistaking the franchise for Creator/{{Toho}} will go as well as mistaking ''WesternAnimation/AvatarTheLastAirbender'' for Creator/JamesCameron's ''Film/{{Avatar}}''.

*** For the same reason, it is best to not call Yuuka's Phantasmagoria theme song as Tiny Little Adamantium", "Omae wa mo", or anything you might have known from social media. It is officially named as "Gensokyo Past and Present ~ Flower Land"..

* Reimu, who's pretty much going to be in perpetual poverty thanks to the utter lack of donations to her shrine.

** Anyone new to Touhou series, especially western fans would find it rather difficult to see many "seemingly pre-adolescence characters"[[note]]Especially Suika Ibuki and The Three Fairies of Light[[/note]] [[HardDrinkingPartyGirl having party and getting wasted on high frequency]]. Not only most of those "seemingly pre-adolescence characters" are actually OlderThanTheyLook, the drinking culture in Japan is also different from many country in the west.
