Literally translated as ''Tale of the Imperial Capital''. A historical fantasy novel by Hiroshi Aramata, '''''Teito Monogatari''''' is a retelling of the history of Tokyo from an occultist perspective, beginning with the Meiji Era and going up to the end of the 20th cetury. Upon his death, the samurai Taira no Masakado cursed the new city and its inhabitants. Over the course of the next thousand years, numerous characters, both fictional and historical, come into conflict with Yasunori Kato, an immortal villain out to harness Masakado's spirit to destroy the city.

The novel won the Nihon Science Fiction Taisho Award in 1987, has sold around some 4 million copies in Japan alone, and is widely considered the first major work to popularize Onmyodo (Yin Yang) magic and Feng Shui in its native country. Of course its immense success has resulted in several visual adaptations. In Japan, the most well known adaptation is the live action special effects film ''Tokyo: The Last Megalopolis''. However because the West isn't so inviting to Japanese live action SPFX films (Godzilla excluded), the most known adaptation over here is the really stylized and repulsive anime version known as ''Doomed Megalopolis''. Both adaptations though are (very) abridged adaptations of only the first 1/3rd of the novel, which has never been translated into English.

!! ''Teito Monogatari'' provides examples of the following tropes:

* ActionGirl: Keiko.
* AllThereInTheManual: The films and the anime leave you with more questions than answers if you have not read the book. You'd have better luck sticking a camel through the eye of a needle than you would have understanding the entire ''Teito Monogatari'' story purely through its cinematic adaptations.
* AlliterativeFamily: Yoichiro, Yukari, and Yukiko.
* AlternateHistory: Reimagines the history of Tokyo from an occult perspective.
* AnimatedAdaptation: ''Doomed Megalopolis'' (duh).
* {{Antihero}}: Yukio Mishima.
* AnyoneCanDie: With the exception of Kato, not many characters make it through all of Tokyo's history.
* ArchaicWeaponForAnAdvancedAge: Tsuchimikado cultists fight the shikigami armed with simple [[WoodenKatanasAreEvenBetter shinais]]. Although this is noted as a rather basic tactic, they do manage to kill many of them before being [[ZergRush outmatched by sheer numbers]].
** In the film, they use [[SimpleStaff shakujo staves]] to corner Kato after he has captured Yukari.
* {{Badass}}: Yasunori Kato.
** BadassCape
* BadassGrandpa: Yasumasa Hirai.
* BadassNormal: Shigemaru Kuroda may pass as a bumbling character, but he can hold his own when the occasion requires it. In the anime, he has mystical powers and can even fend off shikigami with chants.
** Koda Rohan by his own right. He chops dozens of shikigami with his wakizashi and even attacks Kato with it.
* BarehandedBladeBlock: Kato blocks Keiko's tanto by nonchalantly grabbing its blade. Downplayed in that he does blood a bit for the stunt.
* BigBad: Kato, although WordOfGod has stated that he is the [[VillainProtagonist true protagonist]] of the story.
* BigGood: Hirai to an extent.
* BlobMonster: Kato's shikigami seem to be made of a black blob-like sustance.
* BloodMagic: After Kato flees with Yukari, Hirai uses his own blood to power one of his shikigami to find them. The spirit is shown possesing a casual bird which had went through the paper before reach its destiny.
* CaneFu: In the anime, Hirai impales a shikigami with his cane.
* ChainsawGood: The goho doji shows a built-in chainsaw to attack Keiko. This is a reference to old goho doji depictions, where they are drawn wearing a collar of swords.
* ChestBurster: The fukuchu-mushi inside of the nurse breaks out from her back when is summoned by Kato. It's unknown whether the nurse had been possesed by the spirit or instead she ''was'' a disguised spirit all along.
* ClothingDamage: Specially in the anime, for fanservice reasons. Both Keiko and Yukiko end naked when confronting spiritual forces.
* ComicBookFantasyCasting: One perk of the books is that many japanese historical characters plays an important role in the story.
* CoolHorse: Masakado sends one to Keiko at the fourth OVA. It seems to be a furry, equine mystic being.
* CourtMage: Yasumasa Hirai. He is the leader of the Tsuchimikado Family, an onmyodo clan that serves the Emperor.
* CuteAndPsycho: Yukari Tatsumiya while controlled by Kato.
* DangerouslyGenreSavvy: Hirai is wise enough to know a way to protect Yukari from Kato's influence, but Kato knows it too and thus is able to thwart it.
* DarkActionGirl: Kato's female servant in the live action film.
* DemotedToExtra: The classic Meiji era writer Koda Rohan had a much more active role in the novel and live action film. But in ''Doomed Megalopolis'', most of his actions are given to Kamo, a fictional onmyoji. Ogai Mori (another famous Meiji era writer), who was also a major supporting character in the book, is just relegated to a cameo in the cinematic adaptations.
* DeusExMachina: Practically any action on behalf of Masakado's spirit or the Bodhisattva Kannon.
* DrillTank: Gakutensoku is equiped with drills in the OVAs and crushes some shikigami with them.
* DrivingQuestion: What great power is fueling Kato?
* EpicMovie: At the time, the first film was one of the most expensive Japanese films ever made, almost matching Film/{{Ran}}.
* EvilSorcerer: Yasunori Kato.
* FaceFullOfAlienWingWong: In the anime, Kato and his ''kodoku''-controlled nurse use this to introduce a ''fukuchu-mushi'' (worm spirit) in Yukari. The spirit takes the form of a eyeball and is introduced via mouth-to-mouth.
* {{Familiar}}: The shikigami and gohou doji.
* FengShui: Along with onmyodo magic, it was the first modern fictional work to popularize Feng Shui in the Japanese media. This popular interest would serve as a lead up to the academic feng shui "boom" in 1990's, where many Japanese scholars started studying the practice's influence in the history of their country.
* FollowTheLeader:
** It's believed that Baku Yumemakura's incredibly popular ''Onmyoji'' series (also made into a film of the same name) was written in response to the success of this novel (the first ''Onmyoji'' short story emerged 3 years after ''Teito Monogatari'' started being published).
** Within the franchise itself, the disgusting imagery in ''Doomed Megalopolis'' was most likely inspired by the commercial success of hyper violent, perverse "adult" anime like ''Legend of the Overfiend''. Also, the excessive perverse horror elements in ''Teito Monogatari Gaiden'' were most likely inspired by the commercial success of ''Doomed Megalopolis''.
* FromClonesToGenre: If "Modern day Onmyoji" (like Clamp's popular ''TokyoBabylon'' series) even qualifies as a genre, then it originated here.
* FullFrontalAssault: In the climactic battle at the end of the anime, Keiko ends completely naked due to ClothingDamage. In this case, her nudity symbolizes her newfound spiritual purity as a Bodhisattva [[spoiler:which is how she defeats Kato.]]
* GenreBusting: Although Western distributors have insisted upon classifying its adaptations as horror, the original novel constantly gets classified as science fiction by the Japanese. However, it can't be just science fiction because it also has heavy elements of magic and folklore in it, placing it closer to fantasy. In fact, the author first described the novel to an English audience as a "fantasy romance". Also all the historical infodumping in the novel brings it closer to historical fiction.
* GiantFlyer: In the anime, Kato summons a gigantic, flying manta ray-like spirit to besiege the Tatsumiya house.
* TheGhost: Taira no Masakado. Subverted in the anime, in which he appears under the form of a ghostly samurai.
* GoodHurtsEvil: In the anime, [[spoiler:Keiko defeats Kato with this.]]
* GrewBeyondTheirProgramming: At the end of the live action version, the robot Gakutensoku momentarily becomes sentient to defend his master (the historical character Dr. Makoto Nishimura, who is played by his real life son Ko Nishimura) from the last of Kato's shikigami. This is never explained, although it somehow fits with the mysticism around Gakutensoku.
* HandSeals: Onmyodo and other spiritual powers in the series require it.
* HeroesPreferSwords: Both heroes and villains use swords in ''Teito Monogatari''. Koda and Kamo fight with wakizashis, and Kato use a katana at some point.
* HistoricalFiction: Imagines the history of Tokyo as influenced by the supernatural. Also works in numerous historical persons into the plot.
* HotBlooded: Koda Rohan, who doesn't care about the risks if he has his reliable sword.
* HypotheticalCasting: Realized in the form of actor Ko Nishimura, who got to play his real life father Dr. Makoto Nishimura in the live action film. Also legendary Kabuki actor Tamasaburo Bando V was allowed to portray his favorite author Kyoka Izumi in the live action film as well.
* HumanoidAbomination: While Kato is portraited as a almost normal human in the original novels, the anime and the films prefer to portrait him with a much more [[BizarreHumanBiology sinister biology]], complete with TaintedVeins and a unnaturally long face.
* IHaveTheHighGround: Kato in the anime.
* InstantSedation: In the live action film, Kato knocks out a chamber full of onmyoji using a spiderweb-like sedant spell.
* KnightTemplar: Kamo is perfectly willing to sacrifice Yukiko to banish Kato forever.
* LightIsNotGood: Played in the anime. Yasumasa Hirai, the good sorcerer dressed in bright white, is beaten by the dark and evil Kato because in fact he is not morally better than Yasunori - they just are in opposed sides of a conflict, simply using the same kind of magic for different goals. To put it simply, Kato was able to revert the magic arrow against Hirai because the weapon was meant to destroy evil influences, and Kato's power does not qualify as evil.
* LivingStatue: In the film, Kato deploys a large, multi-armed statue to defend his house. In the anime, the ruined temple in which he retreats have some statues guarding it.
* KungFuWizard[=/=]MagicKnight: Most onmyoji in the series are shown commonly using weapons from Japanese traditional martial arts.
** The most obvious example is Kato since in the original novel, he's proficient with a katana and wielded a magical sword.
** Koda Rohan is a skilled swordsman, and later on in the novel he learns magic.
** Kamo, the minor onmyoji, is also skilled with the short sword.
** In the anime, Yasumasa Hirai pulls a daikyū or longbow to fire a magic arrow against Kato.
** Also Keiko qualifies, as she fights with a naginata.
* MakingASplash: The fukuchu-mushi inside of the nurse creates a water explosion as a last resort attack, flooding the Tsuchimikado temple. In fact, the liquid itself doesn't happen to be water, but some sort of non-lethal poison.
* MamaBear: Keiko towards Yukiko.
* MauveShirt: Kamo.
* MarketBasedTitle: In Japan most of the adaptations are simply titled ''Teito Monogatari'' like their source material. But in the West, the OVA adaptation is called ''Doomed Megalopolis'' and the live-action adaptation is called ''Tokyo: The Last Megalopolis'' and both were marketed purely as horror titles. Apparently ''Tale of the Imperial Capital'' doesn't sound ominous enough.
* MentorOccupationalHazard: Justified. [[spoiler:Hirai sacrifices himself to show his devotion to the Meiji Emperor (who has just passed away). It also happens to divine the year of Tokyo's destruction.]]
* {{Miko}}: Keiko Tatsumiya.
* MiniatureSeniorCitizen: Hirai is pretty short in the anime, but not too.
* {{Motifs}}: The rainbow in the live action film.
* MrExposition: The series is extremely guilty of this. Several of the characters are based on real life intellectuals or scientists and they've got a lot to say. This is partly because the author Hiroshi Aramata's profession was a non-fiction writer, scholar and translator before he wrote this work.
* NaginatasAreFeminine: Keiko uses one.
* NightmareFace: Kato shows a demonic face in the films.
* NoNameGiven:
** Kyoka Izumi passes as this in the Western dubs of ''Doomed Megalopolis'', as his name wasn't mentioned in the anime and the dubbers probably didn't a clue about who he was. In the credits, he tend to appear as simply "the fortuneteller" or something like it.
** Same with Shin Mekata, Keiko's father.
** Kato's servant in the film doesn't have a name, or at least, her name is not mentioned.
* NiceHat: Kato.
* NotSoDifferent: Kato invokes this in the anime when he reverts the sacred arrow back to Hirai.
* OldMaster: Yasumasa Hirai.
* {{Onmyodo}}: The first modern fictional novel to popularize onmyodo mysticism in the Japanese media. The whole first portion of the novel is the battle between two rival factions of onmyoji. Only the Tsuchimikado family, the faction that serves the Emperor of Japan, is considered to be the official onmyoji.
* ParanormalInvestigation: Shigemaru Kuroda, the feng shui expert.
* PerkyFemaleMinion: Kato's female servant from the film. Unlike him, she appears to be a regular human onmyoji.
* PoweredByAForsakenChild: Kato's plans often involve using a Tatsumiya girl's spiritual powers.
* PsychicPowers: Spiritual powers tend to manifest in this way.
** MindOverMatter: Mainly used by Kato and Hirai. More seen in the second movie ''Tokyo: The Last War''.
** {{Flight}}: Kato is a master of this.
** MindControl: Some were controlled by him, both using ''kodoku'' and by brainwashing.
* ThePowerOfLove: [[spoiler:How Keiko defeats Kato at the end of the OVA.]] Averted in the books and the first movie.
* RapeAsDrama: The anime does this as the act [[DrivenToMadness drives Yukari to madness]].
* Really700YearsOld: Yasunori Kato.
* RedshirtArmy: Tsuchimikado cultists are pretty much CannonFodder to Kato and his shikigami. More in the film than in the anime, however.
* SealedEvilInACan: Taira no Masakado could qualify as this, but the twist is that he serves as a Guardian Spirit if his rest isn't disturbed.
* SequelHook: At the end of the credits to ''Tokyo: The Last Megalopolis'' there is a tagline that says "Yasunori Kato will return". Also character dialogue at the end implies that the heroine Keiko Tatsumiya would also return. The resulting sequel ''Tokyo: The Last War'' only followed one of these promises and turned out to be a disappointment.
* SquishyWizard: The anime version of Yasumasa Hirai is a subversion. While not a [[KungFuWizard hand-to-hand fighter]], he is incredibly agile and resilient for a man of his age, being able to move faster than a magic blast and survive to an arrow through his torso. On the other hand, his live action film counterpart is never shown in the battlefield.
* SuperSpit: The kodoku nurse can spit [[HollywoodAcid acid]] to blind Hirai's redshirts.
* TheTokyoFireball: Pretty much the whole series is about the citizens of Tokyo coming to terms with the historical disasters afflicting the city. Remember, it covers 90 years of the 20th century history of Tokyo... A lot of happened to the city during that period.
* TheUnfettered: Kato.
* TokyoIsTheCenterOfTheUniverse: The novel is called ''Tale of the IMPERIAL CAPITAL'' for crying out loud. What was the capital of the Japanese Empire in the 20th century?
* TropeMaker: Many modern artistic representations of onmyoji in popular culture owe a lot to this series (including the idea of the Black vs. White Onmyoji clans). Also, the demonic sorcerer wearing an Eastern style military outfit. M. Bison of ''StreetFighter'' fame is undoubtedly the most popular example of this.
* TragicHero: Yukio Mishima.
* WhoYouGonnaCall: Kato's occult mishaps are always first noticed by politicians, scientists, or writers; all of whom are completely unprepared to deal with the supernatural. To compensate, they have to call in the real occult experts which include the official onmyoji (the Tsuchimikado Family) and a feng shui master named Shigemaru Kuroda.
* UrExample: Practically ALL the supernatural/mythological subject matter is taken from the classic Japanese or Chinese folklore, from the medieval tale collections ''Uji Shui Monogatarishu'' and ''Konjaku Monogatarishu'' to classic Chinese literature such as epics like ''Romance of the Three Kingdoms''. For example, Kato's magical impregnation of Yukari is based on obscure folktales about the exploits of King Wen of Zhou, one of China's ancient Emperors. Also, the character of Yasumasa Hirai is a direct descendant of the great onmyoji Abe no Seimei, and many of Hirai's actions in the story are directly based on those of Abe no Seimei from those old folktales. And the scene where Koda Rohan chops off Kato's hand is inspired directly from the legend of Watanabe no Tsuna, the proud warrior who chopped off the arm of an oni at Modoribashi Bridge. In fact, the story of ''Teito Monogatari'' could be seen as a speculative continuation of all these old stories set in modern history.
* [[WarriorPoet WarriorWriter]]: Koda Rohan.
* WizardBeard: The anime version of Hirai.
* {{Youkai}}: Not terribly prominent in this series, however the character of Kato is described as a "oni" as are the creatures he summons. Later on in the novel, Kato summons Water Tigers.
* YouCannotChangeTheFuture: Hirai divines that Tokyo will be destroyed in the Year of the Boar (1923). Guess what happens to Tokyo in 1923?
* YouMonster: Hirai pulls one against Kato both in the anime and the film.
