Baku (Japanese: バク Baku) is a Rank D, Drain-attribute Yo-kai of the Charming tribe introduced in Yo-kai Watch. Introduced at Rank D, Baku was promoted to Rank C in Yo-kai Watch 4.

As of Yo-kai Watch 2, Baku evolves into Bakulia starting at Level 29.

In Yo-kai Watch 3, Baku is one of the Yo-kai required to unlock Shogunyan.

As of Yo-kai Watch 4, Baku is a Rank C Yo-kai of the Mononoke tribe.



Baku has the appearance of a purple and pink tapir. He has yellow eyes with red irises and black pupils. He has small, pointy, horns that are a different color purple than his body but the same color purple as the tuft of fur on his tail. Baku has an orange flower-like design next to his eyes. He also has sharp teeth on both his upper and lower jaws.

Baku has the ability to put his targets to sleep, allowing him to eat their dreams. The dream takes the form of translucent clouds that can also be viewed like a movie if he doesn't immediately eat them.

In the first game, Baku also demonstrates the ability to assume the appearance of a human. This allows the player to go out at night without their parents knowing, as Baku takes the player's place in bed, asleep. Baku's dream eating also removes all traces of tiredness from the player, allowing them to be indefinitely energetic and not feel exhausted.


Yo-kai Watch animation series

In Yo-kai Baku, Baku puts everyone but Nate in school to sleep in order to feast on their dreams. Despite Nate catching him in the act, he refuses to stop, saying that he will only stop after feasting on an incredible dream as he considers all the dreams he's eaten so far as unfulfilling. Eventually Nate summons Shogunyan, whose dream of being eighty feet tall leaves Baku awestruck. After eating Shogunyan's dream, he happily gives Nate his Medal.

Baku is later summoned in Yo-kai Insomni to deal with Insomni, after the Eerie Yo-kai has Inspirited everyone into not getting any sleep the previous night. After their attacks collide, Baku and Insomni appear to have a faceoff in a wrestling arena where the two sleep-themed Yo-Kai duke it out; Insomni eventually triumphs. However, the sequence turns out to be Insomni's dream, and she is revealed to have fallen asleep the instant she was hit with Baku's hypnotic gas.

In The New Yo-kai Watch, Baku was seen in Yo-kai-lifornia where he is among the Yo-kai waiting in line for the release of the Yo-kai Watch Model Zero.

  • Traded (Yo-kai Watch 2): "Baku is tired of eating [player's name]'s dreams. Be Baku's new friend!"



Baku is based on the dream eating youkai of the same name. Originally from China, this beast is described as having "a bear's body, small eyes like a rhino, a long snout, a bovine tail, strong legs like a tiger's and a spotted pelt": overall it resembles a tapir, and in fact the word "baku" is also used to refer to the animal.

This creature will feed on good and bad dreams alike while people are asleep. Those who are woken up by nightmares will invoke its name to let it devour them so they can peacefully go back to sleep, and it's said that even the general Hideyoshi Toyotomi kept a picture of a baku by his bedside to keep nightmares away. It is also said that anyone who sleeps on a baku's pelt will never get sick.


  • Baku is male in the original Japanese version of the anime; however, the English dub of the anime refers to Baku as female. This is probably due to Baku's purple coloring and long eyelashes.
  • In Yo-kai Watch 2, Baku's random nicknames are Dreater, Barnie, Chomp, and Crunchy.
  • Baku tends to refer to himself in third person.
