[[caption-width-right:350:Yeah, most of it's [[{{Rule 34}} kinda like this]].]]

Japan's version of self publishing or independent press.

While doujinshi is traditionally represented as self-published manga, it literally means "amateur publication" and has come to be used as a synonym for any independently published fanwork. Doujinshi produced by a team is usually credited as a "doujin circle" rather than an individual pen name.

Notably, doujinshi may feature completely original content or content derived from an existing intellectual property. Printed doujinshi was traditionally published in limited amounts because of financial limitations. In regards to non-original content, this also assures fans do not step on the toes on the IP's original owners to any large degree, and many companies see amateur work as free promotion. Since doujinshi are also a way of dodging ExecutiveMeddling, doujinshi are less subject to censorship; sexualized and otherwise trangressional depictions are infamous traits of doujinshi, though not actually representative of the whole.

In recent years, there has been an upswing in the activity of both amateur comic artists and professionals wishing to work "outside the system." Concurrent to this has been a support system enabling the production and sale of these works at a scale that few Western artists or writers could accomplish. The biggest semi-annual doujin sale convention, Comiket, has an attendance of some 500,000 people over each three-day event. Because of even tighter financial and legal limitations, doujinshi in the West is represented prominently, if not almost exclusively, [[WebComic on the internet]].

The second most popular form of doujinshi is games, often programmed by one person or a very small group. Probably the most well-known of doujin soft producers, and one of the few ones to cross over into commercial game production is ''TypeMoon''. The ''VideoGame/{{Touhou}}'' games constitute possibly the longest-running series of doujin game productions, since the first one was released in 1996 and there have been 19 games in the series, although there are other potential contenders to that throne.

This has two effects upon anime. The first is that several highly regarded anime have been based on either doujinshi or on artists who established their presence as creators of doujinshi. This includes famous individuals such as Creator/{{CLAMP}}, KenAkamatsu (who dabbles in both), and Creator/YoshitoshiABe (who created the original doujinshi ''Anime/HaibaneRenmei'' is based on.)

The second effect is that a number of anime feature doujinshi as either primary plot points, or sideline elements. Involvement in doujinshi is usually a trait of [[OtakuSurrogate Otaku Surrogates]]. ''ComicParty'' and ''Manga/DoujinWork'' are stories centered around it, while {{Genshiken}} addresses it as a fandom trait; StudioGainax's ''OtakuNoVideo'' is essentially a fanciful self-biopic of the company's origins as a doujin circle.

Interestingly, the first doujinshi were made in America during the early 20th century. They were called "Tijuana bibles," and were eight-page porn comics usually starring cartoon characters or movie stars having explicit and often-comedic sex. (There have been guesses why they were called "Tijuana" bibles, but the reasoning is always obscure.) The creator of LilAbner famously said that he knew he'd hit the big time when Tijuana bibles of his characters began to surface. The first "doujinshi" to raise a major fuss was an underground comic called ''Air Pirates Funnies.'' After the first issue, the existing designs were replaced with [[DisneyAnimatedCanon Disney]] [[ClassicDisneyShorts characters]] in rather explicit situations. This did not please Disney.

Related to the above, doujinshi is not a ''uniquely'' Japanese phenomenon. Doujinshi and doujin circles from other nations are not uncommon and even Japanese media refers them as such.

For a list of Doujinshi, see [[DoujinshiIndex the index]]. See also IndieGame, for commentary on independent game publishing in general. The majority of Doujinshi are naturally {{Crack Fic}}s.

Technically it's also [[NoExportForYou near-impossible]] to import them, and the makers are [[https://www.youtube.com/watch?v=ExD9mnAsqjk&t=30s well aware of this]]. Nevertheless, there are online stores that carry them with worldwide shipping for dedicated importers and artists (mostly musicians) who offered their work outside Japan. Also, there're proxy buyers that you can hire in order to buy everything you want and stores like Toranoana or Melonbooks can't export overseas.

Regarding translations of those works, some artists don't mind translations, as they think it's an extra-promotion for their works overseas. However, many artists are very worried about the blatant piracy of their works, specially by foreigners (artists from circles like LINDA Project, ARCHIVES and Circle Huan have stated that they don't want their works to be published in websites that people outside Japan can access), and they started to take actions against websites and scanlations in 2013.

!!Examples

[[foldercontrol]]

[[folder:Anime and Manga]]
* Harumi Fujiyoshi from ''SayonaraZetsubouSensei'' is, [[MeaningfulName as her name holds true]], a YaoiFangirl. Naturally, she's into slash and a lot of her drawing material involves {{Shout Out}}s and references to other anime, mostly involving material like the above picture.
** When Itoshiki-sensei learns about Fujiyoshi's hobby, he says he put out a few doujinshi in his student days. Naturally, he means self-published literature in a rather old-fashioned format and both characters get the wrong idea about each other's interests.
* In ''MahouSenseiNegima'', Haruna writes Doujinshi, although we don't see a lot of her work. There's even a memorable interlude where she drags Negi to a Doujinshi convention, and he unknowingly picks up a {{yaoi}} hentai, nearly giving Chisame a coronary. There's a good reason that we don't see a lot of Haruna's work; WordOfGod is that it's "[[{{Hentai}} rated 18+"]] (let's not forget that ''Haruna'' herself is supposed to be no older than 15).
* Konata from ''Anime/LuckyStar'' is a Comiket veteran, once recruiting her friends to come with her, during which episode, Kagami spots the yaoi doujin pictured above. Curiosity gets the best of her, and...well...[[http://www.youtube.com/watch?v=Bpoo7NZAPWI hilarity ensues]].
** There is, of course, Hiyori, a doujinshi {{yonkoma}} artist whose [[YuriFan inte]][[YaoiFangirl rests]] practically caused ShippingGoggles to be ''glued'' to her eyes. And yes, she ''does'' sell stuff on Comiket.
* The eponymous club in ''{{Genshiken}}'' has a [[PornStash locker full of Doujins]] in the club room. Later, the club produce their own doujinshi for ShowWithinAShow ''KujibikiUnbalance''. Oguie also draws {{yaoi}} doujinshi, and once accidently spills a large pile of hardcore one she bought in front of the boys in the club.
* Nagi of ''Manga/HayateTheCombatButler'' draws her own, it's her {{berserk button}} if you call it a 'picture diary'〔a ubiquitous form of summer homework for Japanese school children). Several chapters of it have featured well in the anime and manga. The only one who's able to understand the story is Isumi.
* ''Manga/DoujinWork'' is, unsurprisingly, about people involved in the doujin manga scene, with varying levels of success. Apparently, one can make quite a profit in making doujinshi, as Justice can attest.
* ''Comic Party'' is an anime (based on a dating sim game) about the process of making doujinshi. The main character is convinced by a friend of his to use his artistic skills and use doujinshi to "Take over the world." The process of doujinshi is shown in detail, from scripting to printing to selling.
* ''Anime/HanaukyoMaidTai La Verite'' episode 5. Ikuyo Suzuki takes the main characters to Comiket to sell her manga, which (based on its cover) features a (fictional) relationship between the maids Yashima Sanae and Konoe Tsurugi.
* ''Visionary Replay Of Homu Homu'', a [[NotSafeForWork sexually explicit]] Anime/PuellaMagiMadokaMagica Homura/Madoka GirlsLove story.
** The character designer of ''Madoka Magica'', Creator/UmeAoki, makes doujinshi under the pseudonym ''Apricot+''; a ''Madoka'' doujin is amongst works she made under this name.
* ''Anime/MobileSuitGundamWing: Ground Zero'', which actually got published in the US through Viz, and can be distinguished from the official manga by the fact that it doesn't have any of the show's staff in its credits (and because it conflicts with manga that do like ''Blind Target'').
* Nakuru from MayoChiki is one. She's obsessed with making [[BoysLove BL manga]], particularly after seeing the butler for a local rich girl, Konoe Subaru hanging out a lot with OrdinaryHighSchoolStudent [[MistakenForGay Jiro]].
* Chihaya from AsuNoYoichi is another in-universe example. She draws manga and goes to school, but sometimes has trouble trying to fit both into her life. When some of her classmates belittle her efforts, Yoichi beats them up and also chastises them since they lack motivation to do anything themselves but are quick to criticize others for trying to make something of their life. Which then gives Chihaya some more ideas for her manga.
* ''Manga/{{Morefuyu}}'' is based on ''VisualNovel/{{Morenatsu}}'', but taking place in winter instead of summer.
* Episode three of ''LightNovel/JinruiWaSuitaiShimashita'' is an extended parody of the concept. Entirely using {{yaoi fangirl}}s.
* In [[LightNovel/OreNoImoutoGaKonnaNiKawaiiWakeGaNai Ore no Imouto]], the main character, his sister and two of her friends go to Comiket for doujinshi early in the series.
[[/folder]]

[[folder:Comic Books]]
* ComicBook/{{Watchmen}} includes Tijuana bibles as a minor plot device.
[[/folder]]

[[folder:Live Action Television]]
* ''Hybrid Insector'', a SerialNumbersFiledOff version of ''Franchise/KamenRider'' made by the staff of the ''LinebarrelsOfIron'' manga. After nine "volumes" were published, Toei sent an official cease and desist.
[[/folder]]

[[folder:Video Games]]
* Doujin works in this format have a tendency to be created as fighting games, usually emulating the style of ''GuiltyGear'':
** ''VideoGame/MeltyBlood''
*** The plot of this one, however, is considered canon in some ways.
** ''BattleMoonWars''
** ''BigBangBeat''
** ''QueenOfFighters''
** ''EternalFighterZero''
** ''[[VideoGame/{{Touhou}} Immaterial and Missing Power]],[[VideoGame/{{Touhou}} Scarlet Weather Rhasphody]],and [[VideoGame/{{Touhou}} Unthinkable Natural Law]] are all fighting games as opposed to the series usual shmup style. All 3, however, are also canon.
** ''[[ValkyrieProfile Valkyrie Fight]]''
** ''Pokemon: Wild Type''
** ''MagicalBattleArena''
** ''Franchise/WhenTheyCry''
* Doujin shmups are also quite big:
** ''VideoGame/CrimzonClover''
** ''Videogame/{{EXceed}}''
** ''VideoGame/{{Hellsinker}}''
** ''TheTaleOfAlltynex''
** ''VideoGame/{{Touhou}}'' (although, doujinshi of it--yes, ''doujinshi of a doujin game series''--is what the series is far more well-known for.)
** ''{{SUGURI}}'' and ''VideoGame/{{sora}}''
* Doujin action titles are notable as well:
** ''VideoGame/CrescentPaleMist''
** ''{{Dysnomia}}''
[[/folder]]

[[folder:Webcomics]]
* [[QuestionableContent Pintsize]] [[http://questionablecontent.net/view.php?comic=1524 inverts the stereotype]].
* In ''Webcomic/GhastlysGhastlyComic'', Freddy draws doujinshi based on ''ComicBook/ChickTracts'', and after Cosplay Girl converts to Buddhism, she draws a {{Bishonen}} Buddha/Drunk And Bitter Jesus doujinshi (with Jesus as {{Seme}}). Bishonen Buddha then reccomends she start worshippping Fat Buddha instead.
