Yo-kai Watch Image

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. Yo-kai tend not to change their behavior whatsoever and stick to their own different personalities.

Yo-kai are in no way related to ghosts (which is more strongly stated in the manga). Yo-kai may have similar attributes to ghosts like if somebody dies and is reborn as a Yo-kai however, this can only happen if they had a strong reason to become one such as Jibanyan who wanted to defeat trucks to prove himself worthy to see Amy again. All Yo-kai are able to eat, sleep and be in the physical realm unlike ghosts and it is even stated that it is very rare for a human to become a Yo-kai in M01. The only known ghost Yo-kai is Shogunyan, though only in the manga.

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 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. Some Yo-kai do have the ability to die but it depends on who and the circumstances.

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, BBQ, 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.

  • Most promotional outlets usually type out the English spelling as "Yo-Kai" or "Yokai", which is the incorrect way to spell out the word.
    • Though, some of the Japanese products sometimes spell it as "Yokai Watch" or "Youkai Watch".
    • Ironically in Yo-kai Watch Blasters, some instances incorrectly spells "Yo-Kai" with an uppercase K. That can be especially said for the opening cutscene of BLASTERS WAR.
