A pair of rival schools of martial arts, run by a pair of masters who have probably been feuding for years before the series even started. If ''dojo'' is applied to non-Japanese martial arts, its use is an example of the FarEast trope.

Most often, but not always, the two masters were students of the same martial arts style before branching off to [[OpposingCombatPhilosophies different styles]]: the protagonist usually (but not always) learning under [[TheMentor the benevolent master]] who [[PacifistDojo teaches wisdom and self defense]], while the rival school is run by an EvilMentor and encourages its students to be [[ThugDojo ruthless, aggressive and brutal]].

A subset of this trope comes in the form of members of one school (or even an [[ArrogantKungFuGuy unaffiliated challenger looking to show his prowess]]) going to the other dojo and challenging the sensei or top student to a match, usually as an excuse to then completely ransack the dojo, maim everyone inside, and steal a memento of their victory (typically the dojo's marquee). This kind of act, whose exact term is ''dojoyaburi'' (道場破り, "dojo storming"), is TruthInTelevision, and there are stories about brutal dojo wars in historic Japan and more recently in the [[UsefulNotes/MixedMartialArts Brazilian vale tudo]] scene.

Very often comes up in FightingSeries. This situation often involves or ends with the main students from both schools eventually becoming friends or at least allies (usually after [[DefeatMeansFriendship one of them defeats the other),]] effectively ending the feud, or turning it into a [[FriendlyEnemy friendly rivalry]] (if it wasn't already) instead.

[[folder: Anime and Manga ]]

* Being the quintessential FightingSeries (at least in Manga), ''Manga/DragonBall'' of course has this, with Goku learning the Turtle Style from the Muten Roshi, while his rival Crane Hermit's teaches his students styles of brutal assassination. Goku fights two members of the Crane School, the Crane Hermit's brother Tao Pai Pai and his star pupil, Tenshinhan. Tenshinhan defeats Goku the first time, but, in a rare occurrence for this trope, his HeelFaceTurn begins even before Goku eventually bests him.
** The two styles get revived after the events of ''Anime/DragonBallZ'' in ''VideoGame/DragonBallOnline'', though the rivalry is more [[FriendlyRival friendly]] in nature since they're headed by Kuririn/Krillin and Tenshinhan. There's still a schism between their philosophies, inspired by what each took away from their time fighting alongside [[TheHero Goku]]: the New Turtle School is all about [[SupportPartyMember playing support]], while the New Crane School focuses on performing powerful, decisive [[KiManipulation ki]] attacks.
* ''Anime/{{Pokemon}}'' did an episode about a pair of rival Gyms. Each of them tried to be official Gyms, but in the end, neither of them were worthy enough to be declared as an official Gym.
** The games also featured this with Saffron City's two Gyms, one for the Fighting-type and one for the Psychic-type. Only one got to be the official Gym of the city, and the Psychic-type Gym won due to ElementalRockPaperScissors.
* ''Manga/BambooBlade'' has rival Kendo schools.

[[folder: Film ]]

* Creator/{{Jackie Chan}}'s first starring role, ''Film/SnakeInTheEaglesShadow'', is about two rival schools, Snake Hand and Eagle Claw. Eagle Claw has exterminated almost every student from Snake Hand. Jackie becomes the last student of the Snake Hand, and incidentally is able to fight the master of Eagle Claw without being killed, so he learns about his style and [[YinYangBomb combines both of them]] into the style that names the film.
* The central conflict in the Bruce Lee film ''Film/FistOfFury'' is between the hero's Chinese kung-fu school, and an antagonistic Japanese karate school. [[spoiler:By the end, an open conflict between the two schools has left everyone dead except for a few of the hero's friends from the kung-fu school]].
* Turned drastically UpToEleven in ''Franchise/StarWars'' where the Jedi and the Sith teach opposing philosophical approaches to similar martial and magical skill, and have been at each others' throats for twenty-five thousand years.
* Supported by Miyagi Dojo vs Kobra Kai in ''Film/TheKarateKid1984'' and ''Film/TheKarateKidPartIII''.
* Inverted by ''Film/BestOfTheBest'', where the two schools are both honorable and have similar philosophies.
* ''Film/NinjaAcademy''. Oddly enough, one of the students at the {{Hero}} ninja academy is a mime.

[[folder: Literature ]]

* ''The Gone-Away World'' by Nick Harkaway has a rivalry between a ninja school and a mime school. (Yes, the mimes are martial artists. Don't ask.)
* As they draw significant influence from UsefulNotes/EuropeanSwordsmanship, (see RealLife below) the Literature/ElsabethSoesten books have this come up quite often. In ''Bait And Switch'' Elsabeth and Husson nearly get into a duel over the superiority of their respective masters.

[[/folder]]

[[folder: Live-Action TV ]]

* Bobby Wasabi's (whose local sensei is an AdultChild BigBrotherMentor) and the [[ThugDojo Black Dragons]] (a Cobra Kai {{Expy}}) in ''Series/KickinIt''.
* In ''Series/NinpuuSentaiHurricaneger'' and ''Series/PowerRangersNinjaStorm'', three Rangers are from the Hayate/Wind Ninja Academy and two are from the Ikazuchi/Thunder Academy. They clashed at first with the Thunder ninjas acting as PsychoRangers to the Wind trio, but eventually pulled together to fight the BigBad.
** Almost the entirety of ''Series/JukenSentaiGekiranger'' is about the battles between the heroic [=GekiJuken=] Beast Arts school and the evil [=RinJuken=] Akugata school. [[spoiler:They wind up joining forces to defeat the Long and his [=GenJuken=] school after Rio discovers he and the rest of the [=RinJuken=] Akugata have been manipulated by Long.]]

[[/folder]]

[[folder: Professional Wrestling ]]

* This was the whole point of the ''FWA Academy vs. WAW Academy - Academy Warfare'' event. This was ''mostly'' put on, since the academy happened to share some of their students, ''mostly''.
* Coastal Championship Wrestling saw a rivalry between CCW's Bodyslam University and Main Event Training Center after Pablo Marquez left Bodyslam and founded Main Event in protest to Bodyslam's head trainer, Cash Money Alex G, abuse of female students. As it is also in Ft. Lauderdale Florida, The Spot can sometimes act as a third wheel. For those of you worried, this rivalry was just an angle to give CCW Wrestlers something to fight over, Alex G doesn't actually try to hurt students, female or otherwise.

[[folder: Video Game ]]

* ''VideoGame/JadeEmpire'' naturally has a variant on this (It's technically the same school, but the two teachers use different styles). You get to decide which master's teachings come out on top.
* ''VideoGame/PokemonRedAndBlue'': The current official Gym in Saffron City is dedicated to the Psychic-type under Sabrina. Immediately next door is the Fighting-type dojo, which used to be the sanctioned Gym until Sabrina and her followers crushed it, though they still devote themselves to the practice. And then ''the Player'' comes along and sacks the Fighting-dojo ''a second time'', forcing the Karate King to beg him not to take their emblem, instead offering up one of their prize Pokemon.

[[folder: Real Life ]]

* Judo founder Jigoro Kano had to defeat several other jujutsu schools, among them Teshin Yoshin-Ryu and Ryoi Shinto-Ryu, in order to push his own and create the art as we know it. Ironically, he had to endure a massive loss when his school lost to the Fusen-Ryu faction, from where he brought the groundfighting principles to his art.
* So common was this in Japan that Kyokushin karate founder Mas Oyama kept [[BatterUp baseball bats]] on his dojo in case of a dojoyaburi.
* In Brazil, the Brazilian jiu-jitsu and luta livre schools were bitter enemies, as they featured opposite combat philosophies and taught different social demographies (BJJ was the martial art of the high class and Brazilian elite, while LL dojos were cheaper and friendlier to lower classes and poor people). Eventually Brazilian jiu-jitsu side, led by the ubiquitous Gracie family, got the upper hand and expanded internationally via the UltimateFightingChampionship, while luta livre became a shadow of itself and almost faded out.
** Even inside the Brazilian jiu-jitsu side and the very Gracie family there were important dojo wars. Hélio and Carlson Gracie's schools were rivals due to their different approaches to grappling, while another branch of BJJ led by Oswaldo Fadda was against the Gracie doctrine overall.
* Wrestling/NewJapanProWrestling, which boasted that professional wrestling was the strongest martial art in the world, was notorious for shutting the doors to its dojo when someone came in to challenge any of the professional wrestlers and then giving out {{No Holds Barred Beatdown}}s to the unlucky challengers.
* Count Dante's [[http://en.wikipedia.org/wiki/Count_Dante#The_Dojo_Wars Dojo Wars]].
* Comes up throughout the history of UsefulNotes/EuropeanSwordsmanship as well. The rivalry between the Brotherhood of St. Mark and Federfechter in particular stands out, as the former held a monopoly on instruction in the Holy Roman Empire, which the latter infringed upon.
