Night Parade of One Hundred Demons

Go To

"Well around this time of year, yokai come together for the one night parade throughout Japan. A parade with singing and dancing."
Emiko Williams, Erma

The 百鬼夜行 (Hyakki Yagyō), translated into English as "Night Parade of One Hundred Demons" note , is a massive night parade composed of a wide variety of Youkai — demons and spirits believed to be responsible for natural phenomenon of all kinds — where they party and generally cause chaos. It is often used as an idiom for riots and disorderly processions, though some believe it to be a real event in folklore.

Over the years, many different interpretations of how the Parade works have cropped up. Some believe it's led by the youkai Nurarihyon and that it's hosted every summer evening. Humans unprotected by exorcism charms or are not the Onmyoji clan head are killed in the chaos. Despite using the character 鬼 (Oni), the Night Parade is far removed from the term's modern usage to refer to a race of horned ogre-like beings (hence the "demons" translation being standard even when "oni" is otherwise left untranslated); however, it's not unknown in fiction for powerful oni to command a Night Parade, or even be a gestalt entity created from one.

This is said to occur in times when the barrier between Human World and the Spirit World are thin, drawing similar parallels to the Western idea of Samhain.

Compare The Wild Hunt and Walpurgisnacht, events in European folklore where mythical creatures and other supernatural phenomena congress.

It's stated that these spirits will eventually fuse with him over time, transforming him into the apocalyptically-powerful "Thousand-Demon Devil". Eventually Senya earns the Undying Loyalty of all 1000 youkai and realises that even if he loses his humanity he can still decide what he evolves into. In response the youkai transform themselves into arms, causing Senya's monstrous appearance to permanently morph into a messianic one modelled after Kannon of the Thousand Open Hands.

    Film — Animated 
  • The Parade in Paprika is a dream that induces madness in whoever gets it inspired by the Hyakki Yagyo, right down to invading the real world.
  • Operation: Specter in Pom Poko is a display of illusory magic practiced by the Tanuki elders of Shikoku that simulates a ghostly parade of youkai and demons as part of a last-ditch attempt to protect Tama Hills from human development. Since the humans of New Tama are not as superstitious as those in Shikoku, it winds up being confused for a festive piece of advertisement for a local theme-park company, made all the more insulting since one of the Elders wound up dying from the strain of it, and the revelation that it failed ended up driving a second one mad.
  • While it is not stated outright, the plot of Spirited Away implies that this is occurring during the film's story. Chihiro and her parents end up trapped in the Spirit World when they stay at the abandoned amusement park before sunset, something that is commonly believed to happen to humans who happen upon the Hyakki Yagyo. The fact that it is set in an amusement park with a "restaurant row," in and out-going cruise ships and a fully-stocked bathhouse hints that this is occurring in the middle of a festival, which supplementary material suggests is a yearly event.

  • The Girl With Ghost Eyes, set in San Francisco's Chinatown, features a similar parade early on (with its liminal aspects particularly plot-relevant). The author points to Chinese tradition for the parade's characteristics, but, for want of an authentic Chinese name for the whole thing, calques one from Japanese.
  • Xia Jia's "A Hundred Ghosts Parade Tonight" is named after and features a Chinese version of the parade as an event regularly organized by the denizens of Ghost Street, an abandoned amusement park filled with cyborgs and robots modeled after mythical and folkloric characters. The highlight of the parade is supposed to be the abduction of one of the tourists and their rescue by the heroic Yan Chixia, but by the time of the story the only candidate for abduction is the protagonist Ning.

  • The music video for Denki Groove's "Mononoke Dance" features a human couple getting pulled into a cross between the Hyakki Yagyo and a rave. While the girl has a great time dancing (and flirting) with the various monsters, the guy is a Butt-Monkey who's terrorized and bullied by all the youkai, and at one point gets press-ganged into turning a Wheel of Pain that powers the DJ's booth.
  • The music video for Queen Bee's "STARRY NIGHT" features a Hyakki Yagyo march on top of a power line.

    Tabletop Games 
  • Exalted: Referenced by the 3rd Edition bestiary, which is titled Hundred-Devils Night Parade.
  • Forgotten Realms: "Night Parade" was a Second Edition module where monsters from the Demiplane of Nightmares plotted to infiltrate the Prime Material Plane and unleash their kin. The full size of the Night Parade was never revealed, but it was in the thousands.
  • Pokémon Trading Card Game: The illustration rare print of Gastly from the Japanese "Wild Force" expansion features the entirety of Gastly's evolution line marching in hordes on the street, in reference to this trope.


    Video Games 
  • Ghostwire: Tokyo: This is one of the events that one can see after everyone in Shibuya is turned into Empty Piles of Clothing. The Database says:
    Hyakki Yako are amalgamations of Visitors. Should you encounter one, you'll be transported to an alternate dimension. Defeating all of the Visitors will return you to Shibuya along with any spirits they were holding captive.
  • Monster Hunter: Rise: A central event in the story is a reoccurring catastrophe known as the "Rampage", where all the local monsters inexplicably go crazy and begin destroying everything in sight in a stampeding mob (later revealed to be caused by the mating cycle of two Elder Dragons, Ibushi and Narwa). Many of the new monsters also take heavy inspiration from Youkai and the specific setting is strongly Wutai based. The description on the Japanese website makes the comparison even more obvious by calling it "The Night March of One Hundred Wyverns".
  • Ōkami: The Devil gates and Devil gates cave trials are know as Hyakki Yagyo in Japan.
  • Oreshika: Tainted Bloodlines features the "Feast of All Demons", an event that happens once every in-game year, filled with many youkai that often drop good rewards. In order to advance the plot, you need to attend the event and defeat the boss there.
  • In 2018, Pokémon launched the 百ポケ夜行 Hyaku Poké Yako line of merchandise, which heavily features Pokémon based on youkai such as Froslass, Ninetales, and Mawile. The key artwork for the merch line has all the featured Pokémon marching in a nightly parade.
  • Touhou Project: One of the oni Suika's Boss Subtitles is "Tiny Night Parade of One Hundred Demons". She can also split herself into multiple smaller versions of herself, make herself gigantic, and attract people to parties thanks to her power of controlling density (population density in the latter case).
  • Appears in the Yo-kai Watch franchise in the form of a randomly-triggered rhythm minigame, referred to in the English translation as the "Kaos March". In order to trigger it, the main character must walk around the Downtown Springdale area on a clear night, when the in-game clock is between 9 and 12 PM. There is a chance that he or she will stumble upon a group of marching Yo-kai that will invite him or her to join them. The player must move the stylus and tap the touch screen in sync with the music in order to win. Once the Kaos March has first been discovered, it can be triggered again by speaking to a certain NPC Yo-kai. It appears in both Yo-kai Watch 2 and Yo-kai Watch 3.

  • In Erma, Erma's family are invited to Japan by her maternal relatives, the Yureimotos, to take part in the Night Parade. It is implied that while it is a fun party to be involved in, the sheer anarchy of it can be dangerous, hence why Fumiko objects to her father's idea to involve the servants for fear of their lives.

Operation: Specter

Operation: Specter is a display of illusory magic practiced by the Tanuki elders of Shikoku that simulates a ghostly parade of youkai and demons as part of a last ditch attempt to protect Tama Hills from human development. Since the humans of New Tama are not as superstitious as those in Shinkoku, it winds up being confused for a festive piece of advertisement for a local theme-park company, made all the more insulting since one of the Elders wound up dying from the strain of it.
