Relationships[]
Komasan and Komajiro[]
Mamakoma is the mother of Komasan and Komajiro and deeply loves and cares for her two sons.

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.
Komasaburo[]
Komasaburo is Mamakoma's adopted human son. She deeply cares about him, and understood that she may not be a perfect fit as his mother, due to being a Yo-Kai. However, she ended up staying with him because Komasaburo loves her back.

Trivia[]
- Mamakoma is the first komainu Yo-kai to be female. The second would be Komami.
- Mamakoma's English name is only known to exist because of an English-language prototype of the Yo-kai Watch Model U toy. Due to this, the exact spelling of the name (and whether or not her name is still officially "Mamakoma") is unknown. She shares this with Santa Colossus.
- Interestingly, Mamakoma 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, Mamakoma's Wib Wob shows her entire body.
- Mamakoma's U Medal is the only Yo-kai Medal to have its text obscured by the artwork.
