Youkai are a widely-varied collection of various supernatural creatures that pop up in Shinto religion. They have a lot in common with The Fair Folk from Western folklore. Some youkai are good, others are evil, and many are different. Some are mischievous, others avoid humans entirely. Shinto is an animist religion, and youkai are often associated with natural features such as forests and mountains. This word is often translated as "demon" in Western translations, but that does not adequately describe the creatures in question. The closest true Western equivalent is probably that of the ancient Roman genii or spirits.
Supernatural creatures drawn from Western sources often turn out to seem more like youkai in Japanese works. For instance, vampires. In the West you've got Nosferatu—a grotesque, undead monster who burns in sunlight and murders to preserve his hideous unlife. In Japan you've got exceptionally cute Fan Service protagonist Moka Akashiya, who is not undead, harbors no ill-will towards the sun, and drinks tiny amounts of blood that leave her "victim" light-headed at worst, but who has a Super-Powered Evil Side who can (and will if you look at her the wrong way) kick your ass thoroughly.
Henge, a subset of youkai, are magical animals with Shapeshifting powers and human intelligence. They often assume human form and get into all kinds of mischief. Kinds of henge include Kitsune, Tanuki, and Nekomata.
Obake is another Japanese word that can indicate some type of monster. Derived from the word for “to change,” it generally covers the subset of youkai that includes shapeshifting animals and Animate Inanimate Objects. Confusingly, however, the word obake can also be used to refer to ghosts, also known as yuurei. See Stringy-Haired Ghost Girl for more information.
The list presented below is by no means complete. Many types of Youkai are exceedingly rare to find in modern media and so are not included. On the other hand, Kitsune, Kappa and Tanuki have garnered enough examples to warrant their own pages.
A seemingly ordinary cat that develops magical nature through long life. It looks like an ordinary house cat, except for the tail, which splits into two at half-length. While much smarter than it used to be, a nekomata remains just as whimsical, which may be dangerous with its new found powers of illusion and Necromancy. It's said a cat will become a nekomata after turning 100 years old, where upon its tail splits, it starts using human speech, some how gains transformation powers, a greater intelligence, and other odd abilities. The name is often used and confused for catgirls. May be a Mega Neko.

- The X-Antibody version of Tailmon from Digimon is two-tailed.

And since this world is full with Cute Monster Girl, her form become inverse, with human form being true one.
- Nekogami Yaoyorozu: Mayu and Sasana as well as their family are cat gods.

- This can be the only explanation for a good half of the monstrosities strewn throughout Steve Moraff's Dungeons of the Unforgiven.

These are mountain spirits that share some things in common with trolls and ogres. The word is almost always translated into English as "demons" or "ogres."

- Tarakudo and the other Oni Masks, the antagonists of season 4 of Jackie Chan Adventures.
- Meisuke "Nube" Nueno sealed an Oni in his left hand, and it becomes the signature element of the series. Two other Oni show up, younger siblings of the former, with vastly different agendas. Nevertheless, they are all presented as supremely powerful, destructive demons and the greatest threats to appear in the series.

Oni appear as random monsters, but are concentrated in the Forest of Lianshan, where they are said to be the cursed spirits of humans who turn bestial over time. Killing them doesn't remove the curse, and their monster forms will reappear after a time.

Some incarnations sleep with lone travelers to steal valuable body warmth, others will simply make them get lost during their travels to freeze to death, yet others will kill travelers by tricking them into touching them or a baby they hold in their hands. More benevolent Yuki-onna will either lead the victims to safety or leave them alone; the more wicked ones will lead them astray to begin with and use them.

- Father-Mother appears to be inspired by this, if not explicitly based on them. He/She sports the phallic nose, and general crow theme.
- Kurama-hime from Urusei Yatsura is a Cute Monster Girl version of the Tengu (though she trades the long nose for little crow wings on her head and is thusly an avian Petting Zoo People). She's also served by more traditional Karasu Tengu (which are runty little humanoid crows).
- In the Shoujo manga Black Bird the male "romantic" lead is a tengu, as well as all his pretty-boy relatives. Other spirits also fight with him for the protagonist, because drinking her blood gives a spirit immortality and marrying her brings prosperity to his clan.

- So far, only Karasu Tengu appear in Monster Girl Encyclopedia, although their profile does mention Daitengu. They mostly avoid human, but will kidnap men during mating season. They only seek a Nice Guy, and can be driven away simply by verbal insult.
- Represented in the Monster in My Pocket line.
- Tengu are present in the mountainous regions of Muramasa: The Demon Blade. Both purple/black and red/white varieties look roughly 50% human and crow. The red/white ones explode when killed.

- In the Movie and third season of Mighty Morphin Power Rangers, Tengu warriors (spelled Tenga in season 3) acted as footsoldiers for the bad guys. Their designs favor the crow aspect of the myth, as opposed to the human.
- There is also a Monster of the Week in the third season of MMPR (Professor Long Nose) whose design adheres more to the classic tengu image.
- Shin Megami Tensei, like the oni example above, has several types of Tengu running around: from tiny annoyances (Koppa Tengu), to evil corruptive spirits (Karasu Tengu) to competent, powerful warriors (Kurama Tengu), each modelled after a different branch of Tengu.

- Bakumon of Digimon, goes by the name Tapirmon in the dub.
- The Final Boss of Parodius for the MSX is a baku named Bug (a Punny Name that works better in Japanese).

Makoto inadvertently took the latter as a pet, and, as the elder ones tried to find it, they brought catastrophe to the town—nearly killing Nube by slicing him in half until Makoto finally released the younger kamaitachi and it healed the teacher with its balm.
- Digimon World 3 Kyuukimon (not to be confused with the aforementioned Kyuubimon) and Reppamon of Digimon.

- Several shorts exclusive to the Seikimatsu Occult Gakuin DVDs center around a pet tsuchinoko kept by Maya and Ami.

- One Hellboy story has him accidentally running across a household of Nukekubi. Needless to say, he hits them and pokes fun at them. The story was imported word-for-word into the OVA Hellboy: Sword of Storms.
- Sword of Storms also has female Rokurokubi show up later as well.
- In Yu Yu Hakusho, one demon that showed himself to Yusuke after the Hell Tournament Arc, with news on his demon ancestor was an example of a Rokurokubi with his surprisingly human looks for a demon. It was night time as well.
- Rokurokubi are a HUGE part of Hell Teacher Nube, as the Genre Blind Miki insists on trying out techniques for astral projection and, instead, ends up turning herself into a rokurokubi. She's unable to control this state at first, and honestly believes that Nube, as the resident exorcist, will kill her because she's become a youkai, but he simply shows her how to control this new side of herself and the ability to extend her neck (sometimes across town) becomes another aspect of her personality... one that she uses incessantly to play pranks, annoy others, and, in at least one occasion, save the lives of herself and her friends.
