Yo-kai Watch Image

Various Yo-kai interacting with the human world.

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 influence is responsible for every one of the strange, paranormal events in the human world. Most of these influences range for example, 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 Yo-kai Watch. In some cases, some Yo-kai can disguise as humans by putting a magical leaf on their heads, such as seen by Komasan and Komajiro in the anime, or by more conventional forms of shape-shifting, such as Kyubi. 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 Manjimutt or Snartle.

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

Several Yo-kai used to be humans (such as Hungramps, Manjimutt or Venoct), animals (such as Cricky or Jibanyan), or even inanimate objects (such as Wazzat or Brokenbrella). Though the process for becoming a Yo-kai is largely unknown, most Yo-kai develop an attachment to an important place of their previous lives, with several having "unsettled business" to fulfill; however, doing so does not make them pass to the other side.

Though most Yo-kai, being technically ghosts, cannot "die" in the strict sense of the word, they can have their souls (Soul Gems) forcefully removed, leaving an empty shell behind. The "death" can be reversed by returning their souls, however. Those who can die simply have a supernaturally long life span.

It is not yet clear when were the first Yo-kai came into existence, though several of them were around since the Sengoku Period. Some Yo-kai, known as the Classic Yo-kai, can be found until 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 this time period. Likewise, Merican Yo-kai can be found in St. Peanutsburg, U.S.A., implying that other areas of the world have their own individuals of 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, and Slippery. In the video games, each of the tribes their own strengths and rarity, 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 be revealed so far. Every tribe has their own summoning chants when a Yo-kai from that tribe is summoned.
