History AnachronismStew / AnimeAndManga

* ''Manga/JoJosBizarreAdventure'': A scene set around 1933 includes Joseph Joestar reading a comic book with an ad for 1965's ''Series/GetSmart'' on the back cover.

** The end credits of ''Film/Naruto7TheLast'' show Hinata, Sakura, Ino and Tenten taking a selfie with what appears to be a smartphone. Note that this takes place during the TimeSkip between Chapters 699 and 700.

** And QueenVicky wears CoolShades. Whether or not these anachronisms are intentional is far from clear.

* OsamuTezuka loved to throw in gross anachronisms into his historical works. The first volume of ''Manga/{{Phoenix}}'', for instance, has an ancient Japanese general leave to read a ''Literature/JamesBond'' novel (which may be a {{Woolseyism}} on the part of the translator), and things like televisions and refrigerators are worked into other volumes of the series via BambooTechnology.

* ''LightNovel/TheCircumstancesLeadingToWaltrautesMarriage'' is set in NorseMythology, but features things like the metric system and modern day-style swimsuits. The main characters do question where these things come from.

* ''Manga/SoredemoSekaiWaUtsukushii'' averts it for most of the series, which leans toward a vaguely 18th-Century sensibility, particularly with regards to architecture and fashions. However, once the story returns to Nike's home country we're treated to, of all things, a full-blown idol concert, complete with speakers, spotlights, and wireless microphones. And later on, during [[spoiler:Nike and Livi's formal engagement ceremony]], they bring out what looks like a ''film projector''. An exasperated Neil even comments on how he has no idea what these things are supposed to be.

* ''Anime/TonoToIssho'' is set in the Sengoku Period, but some characters wear modern clothes, and apparently anime and microphones have been invented.

* In ''Manga/AkameGaKiru'', though the setting appears to be in a medieval period, there are some modern day technology used commonly throughout the show, such as guns, electric lighting, large leisure boats, and some of the clothing such as a suit and necktie. Chelsea also sports some headphones and regularly sucks on lollipops.

As a music buff, Kubo drops in strange music references all the time. In flashbacks to a century ago, Shinji was listening to jazz from the World of the Living, which he says is just kicking off, but the first "jazz" recordings date to 1917. However, Kubo includs an {{omake}} in the associated volume where he tells Shinji that, naturally, jazz didn't really exist a century ago. Cue comical bafflement from Shinji over what he's actually listening to. At the time period in question, the music that was just kicking off was ragtime, which was the genesis of jazz and which is sometimes included under the "jazz" category.

* Soul Society in ''Manga/{{Bleach}}'' appears to resemble Edo-period Japan in clothing and architecture. But the Shinigami use cell-phone like devices, have a highly advanced research division (complete with MadScientist), and several characters sport sunglasses or other modern attire.
** Which is understandable -- Edo period stuff but they can visit the modern world. Just when you become okay with it you get a {{flashback}} with computers and sunglasses around the turn of the 20th century Earth time, with Jazz, in Edo period Soul Society. Note that the first {{Jazz}} recordings date to 1917, and that sunglasses started being mass-marketed in TheThirties.
*** An omake in the volume the chapter appears in has the author telling the character (Shinji) that, naturally, jazz didn't really exist at that time period in the real world, cue the comical bafflement of the jazz-loving character who must be wondering what on earth he's listening to if it doesn't exist. At that time period, modern jazz may not have existed, but its very early genesis was already beginning to flourish so... it kinda did exist, after all.

** Brought to a head in the final chapter which shows the titular character using a sleek laptop computer.

* Even if you ignore the HumongousMecha, ''Anime/NobunagaTheFool'' still features UsefulNotes/OdaNobunaga, JoanOfArc, and Creator/LeonardoDaVinci together, when in RealLife, they weren't even alive at the same time.

** There's also people like JackTheRipper, [[RasputinTheMadMonk Rasputin]] and UsefulNotes/AlCapone running around to make it even ''more'' confusing.

** {{Lampshade|Hanging}}d at one point when America is using a Modern Era computer during WorldWarII. England tells him to stop showing off.

** Anime only: the holy roman empire gets woken up be an alarm clock in the 16th century.

* ''Anime/SamuraiChamploo'' opens the series with a title card declaring that it is not a historical document. It then gleefully throws everything it can get its hands on (from hip-hop to baseball) into the Edo period of Japan. Doubly amusing because baseball is a ''hugely'' popular sport in modern Japan.
