Various Yo-kai interacting with the human world.

The Yo-kai (Japanese: 妖怪 Yōkai) are a folk of supernatural beings and one of the main focuses of the Yo-kai Watch series.


Yo-kai are spiritual beings whose influences are responsible for almost every one of the strange and paranormal events in the human world. Most of these influences range from sudden changes in the behavior of people or abnormal weather in otherwise normal days, as well as unexpected landscape changes or control over a different force of nature.

With some exceptions, most Yo-kai are invisible to humans without the help of an item such as the Yo-kai Watch. In some cases, Yo-kai can join human societies by putting a magical leaf on their heads, as seen by Komasan, Komajiro and Rawry in the anime; through more conventional forms of shape-shifting, such as Kyubi, Mimikin and Robonyan; possession of others, such as Infour; or even choosing to manifest themselves at will in a certain way, such as Lord Enma and Toiletta. Also in the anime, some Yo-kai are made permanently visible due to the circumstances of their death or the origins of their Yo-kai conversion, such as Pandanoko, Manjimutt and Snartle.

Most of them being based on the actual youkai and other mythological entities from traditional folklore and even certain fictional characters from popular culture, most Yo-kai have unusual body compositions, such as being single- or multi-eyed or even multi-limbed; others may be based on inanimate objects, which are known under a sub-category of Yo-kai known as Tsukumogami (Japanese: 付喪神) or even food, also ranging from being based on animals like mammals, birds, fish or insects and even more traditional demons or mythical creatures.

Many Yo-kai used to be humans, such as Frostina/Blizzaria, Hungramps, Spoilerina and Venoct; animals, such as Cricky, USApyon, Tomnyan and Jibanyan; or even inanimate objects, such as Wazzat, Dummkap and Brokenbrella. Though the process for becoming a Yo-kai is largely unknown, most Yo-kai develop an attachment to an important place or part of their previous lives, with some having unsettled business to fulfill; however, doing so does not make them pass to the other side.

Though most Yo-kai, technically being ghosts, cannot die in the strictest sense of the word, they can have their Soul Gems forcefully removed, leaving an empty shell behind. The "death" can be reversed by returning their souls, however. Those who can or are able to die simply have a supernaturally long life span. It was also revealed that some Yo-kai can in fact be exorcised and sent to the other side.

It is not yet clear when the first Yo-kai came into existence, though several of them were around since the Sengoku period and Edo period. A group of earlier Yo-kai, known as the Classic Yo-kai, existed at least 60 years prior the start of the series, along with other Yo-kai which can also be found in the present, with others being encountered only in certain time periods. Likewise, Merican Yo-kai can be found in St. Peanutsburg, U.S.A., implying that other areas of the world have their own individual Yo-kai, not just Japan.

Tribes of Yo-kai

Main article: Yo-kai Tribes

Originally, every kind of Yo-kai were divided into the eight main tribes: Brave, Mysterious, Tough, Charming, Heartful, Shady, Eerie and Slippery. In the video games, each of the tribes has their own strengths and rarities, and if two or more Yo-kai of the same tribe are adjacent to each other, they will receive a Tribe Unity bonus. In Yo-kai Watch 2, the Wicked were introduced, consisting of the Wicked Executives and the Wicked Servants. In Yo-kai Watch 3, the Hagure debuted as the 10th main tribe with Android Yamada being the first from the tribe to officially be revealed so far, and the Yo-kai Watch Busters subseries introduced the Enma. Every tribe has their own summoning unique chant when a Yo-kai from that tribe is summoned.
