Koma Kaachan is a giant, white, blob-like Komainu Yo-kai with purple swirls.


Koma Kaachan is very motherly and loves children, evidenced by how she happily took in Komasaburo in Yo-kai Watch the Movie: Lord Enma and the Five Tales, Nyan!.


Komasan and Komajiro

Koma Kaachan is the mother of Komasan and Komajiro and deeply loves and cares for her two sons. She is commonly written to by Komasan, and they both wish to take care of her in the off-hand chance she visits. This is shown in an episode of the Yo-kai Watch anime where Komasan goes to a sushi restaurant to see if it would be something she would like.


Koma Kaachan is the mother of Komami, the younger sister of Komasan and Komajiro.


In Yo-kai Watch the Movie: Lord Enma and the Five Tales, Nyan!, Koma Kaachan temporarily becomes the adoptive mother of Komasaburo.

In the anime

Yo-kai Watch anime series

In M02, Komasan and Komajiro visit Koma Kaachan, finding out that she has become the adoptive mother of a human baby that she named Komasaburo. After a few antics during their visit, Koma Kaachan reunites Komasaburo with his parents.

She briefly appears in one of the flashback scenes of Let's Go To Work!: Yo-kai Daycare, where she drops off Komasan and Komajiro in a nursery after Komasan realizes how much he misses his mother.

In M03, Koma Kaachan was summoned by Nate to save Kanami from suffering a fatal fall. It turned out that Nate got her Yo-kai Medal from Komasan as a thank-you gift.

She briefly appears in EP154, where Komasan and Komajiro claims her responsibility for creating a oval-shaped crop circle to Agent Blunder and Folly.

Yo-kai Watch!

Koma Kaachan appears in YW002. In the episode, she calls both Komasan and Komajiro to announce a new little sister joining the family. She shows them a social media website called Inzuragram, where it shows photos taken from the person, and kindly asks them both to find her.


Koma Kaachan is a combination of koma, referring to komainu, and kaachan (Japanese: 母ちゃん "mother").


  • Koma Kaachan is the first komainu Yo-kai to be female. The second would be Komami.
  • Interestingly, Koma Kaachan has two official tribes. The first tribe is the Charming tribe, which she was revealed to be in during her introduction in Yo-kai Watch the Movie: Lord Enma and the Five Tales, Nyan!. The other tribe is the Heartful tribe, which she was revealed to be in when she was added to Yo-kai Watch: Wibble Wobble for the Gates of Whimsy ~The Search for Komami~ event.
  • While most Wib Wobs in Yo-kai Watch: Wibble Wobble only show the Yo-kai's head, Koma Kaachan's Wib Wob shows her entire body.
