** A scene in ''Manga/JoJosBizarreAdventureBattleTendency'', set in the 1930s includes Joseph Joestar reading a comic book with an ad for 1965's ''Series/GetSmart'' on the back cover.

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

* ''Anime/DaikyouryuNoJidai'' features three kids from the present day being transported to the Cretaceous Period to witness the last days of the dinosaurs. Despite being set in the Cretaceous, dinosaurs and other reptiles from the earlier Triassic and Jurassic periods make appearances despite already being extinct for million of years by then. The most jarring example is a cameo by ''Edaphosaurus'' a pelycosaurian synapsid that lived ''even earlier'' (in the Permian Period) and thus was already extinct when the first dinosaurs evolved. There is also the Ice Age happening right at the beginning of the Cenozoic Era, instead of millions of years later in the Pleistocene.

** China is wearing a [[{{Qipao}} changshan]] when he first meets little Japan in the bamboo forest.

* Certain ''[[Anime/MobileSuitGundam Gundam]]'' series tend to blend archaic aesthetics with [[RecycledInSpace space age society and technology]]. For example, most One Year War themed series feature World War II aesthetics, ranging from Zeon uniforms being Wehrmacht knockoffs to Federation ground troops using full sized walkie-talkies and backpack sized communication gear in the field, while later UC series (as well as ''[[Anime/MobileSuitGundamWing Gundam Wing]]'') tend to place emphasis on European fashion and cultural themes (i.e. the guillotine in ''[[Anime/MobileSuitVictoryGundam Victory Gundam]]'') in spite of their advanced technological settings.

* In-universe example: An early episode of ''Anime/{{Pokemon}}'' featured a carving of a [[{{Mon}} Mewtwo]] on one of the external walls of what appears to be a century-old lighthouse. [[{{Mon}} Mewtwo]] wasn't even created until the second half of the Kanto arc.

* In ''Webcomic/AxisPowersHetalia'', [[MoeAnthropomorphism the Roman Empire and Germania]] are occasionally seen interacting with characters during the first half of the twentieth century.

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

** {{Lampshade|Hanging}}d at one point when America is using a Modern Era computer during UsefulNotes/WorldWarII. England tells him to stop showing off.
** Anime only: the holy roman empire gets woken up by an alarm clock in the 16th century.

** Near the end of the Buddha series, Buddha heals Prince Crystal by placing his finger on the tumor that is killing him. One of the prince's advisors said he heard of this power before, and asks Buddha if he's [[Film/ETTheExtraTerrestrial E.T.]] A few chapters later [[UglyCute E.T.]], [[Franchise/StarWars Yoda]], and Cherry (from Urusei Yatsura) make a cameo appearance.

* The ''Manga/DragonBall'' series is full of this. Technology is so advanced that objects larger than houses can be stored in a tiny, pill shaped capsule. On the other side of the spectrum the world outdoors is filled with saber tooth tigers and dinosaurs (themselves anachronistic if you know your pre-history). That's all it gets early on in the series, but then we find large cities with spherical-shaped buildings in a setting we've mostly seen looking like ancient China. Even the cities themselves have this: you'll see cars driving by on roads, and in the background see sky tubes for the flying vehicles. That is shortly before the heroes explore a pirate cave guarded by a robot with WWII-era machine guns. In one scene the characters are in a personal flying plane from one of the capsules and are sent a picture... via ''fax!''
** Somewhat explained by the fact that 300 years ago, they had modern technology, including machine guns, but that was also when King Piccolo devastated humanity. Which means that the SchizoTech is because Dragon Ball is a post-apocalyptic setting.

* InnocentsShounenJuujigun While not to an extreme extent, there are enough inaccuracies and blurring of centuries that it borders on this. (Ex: the types of houses shown are from much later than the 13th century)
* In ''Manga/BoardingSchoolJuliet'', the characters adhere to samurai codes of honor, take steam trains, and have [=LCD=] televisions. (And for [[RuleOfDama dramatic reasons]], there are no cellphones.)

One of the prince's advisors said he heard of this power before, and asks Buddha if he's [[Film/ETTheExtraTerrestrial E.T.]] A few chapters later [[UglyCute E.T.]], [[BadassGrandpa Yoda]], and Cherry (from Urusei Yatsura) make a cameo appearance.

*** Speaking of, the [[{{Shinigami}} Reapers]] have access to modern technology such as plastic-framed glasses, a modern wristwatch, and the aforementioned chainsaw. Justified since they're supernatural beings, and since they can predict death before it happens it's possible they have access to time-related magic.

* ''Manga/BlackButler'' is set in London in late 1888, when Jack the Ripper was at large. The maid in the house washes clothes with a washing machine and laundry detergent sold in a box, the chef cooks food with a flamethrower, [[LethalChef badly]], and Jack the Ripper fights with a chainsaw.
** And there are cell phones used by people who look like they're in the mafia.
** And {{video game|Genres}}s existed.
** And [[UsefulNotes/QueenVictoria Queen Vicky]] wears CoolShades. Whether or not these anachronisms are intentional is far from clear.
** As the manga's carried on, the anachronisms have been toned down, mostly being either aesthetic (women in [[{{Stripperiffic}} not enough clothes]], and so on) or difficult to fix due to plot (allowing there to be only five or six servants on an estate makes maintaining TheMasquerade easier, etc.). The remaining offenders are the otherworldly [[{{Shinigami}} Reapers]], who have access to modern technology such as plastic-framed glasses, a modern wristwatch, and the aforementioned chainsaw.
** Justified in one arc, where technology from the 20th century only existed in the 1800's thanks to a LensmanArmsRace; the existence of this technology drove the arc's plot ''because'' it was so far ahead of its time and everyone wanted to steal it.
** Eventually this trope was invoked and made plot-relevant, as a reaper directly confirmed that humans can gain advanced technology and scientific knowledge by making contracts with demons and other supernatural forces. In other words, anytime you see something that doesn't belong in that time period, [[ChekhovsGun keep track of it.]]

* In ''Manga/AkameGaKill'', 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.

* In ''Manga/{{Gintama}}'', aliens (known as Amanto) forcibly opened up Japan instead of Commodore Perry and crew, bringing all sorts of new-fangled technology to Edo (space travel, electric fans, bazookas, etc). And since ''Manga/{{Gintama}}'' is ''supposed'' to be a GagSeries, you get things like the main character being a big fan of Weekly Shonen Jump (most notably ''Manga/{{Bleach}}'', since he uses a sword too), {{idol singer}}s, and countless references to modern pop culture mixed in with more traditional fare, like TheShinsengumi, the Jooi resistance, and the Oniwabanshu (though disbanded in the series).

* ''Manga/{{Berserk}}'' includes--in addition things that come straight from the imagination of the artist or only exist in the fantasy genre--many types of weaponry, armor, architecture, costumes, ships, etc. that did exist in real life, but in widely separate time periods. That's what gives us things like 14th century helmets, 16th century palaces, 17th century frigates, and 18th century ballgowns all mixed up together. It is a fantasy work incorporating historical elements rather than a historical work incorporating fantasy elements, so it's best to just appreciate the level of detail. The author is on record as saying he's perfectly aware that he depicts forms of armor, for example, that weren't all used at the same time, but decided to throw in [[RuleOfCool whatever he thought would be cool]] instead of limiting himself.
