Momon-Jii (百々爺, really old man) is Yōkai and antagonist in the GeGeGe no Kitarō manga and anime franchise, appearing most notably in The Great Yōkai Trial.

Momon-Jii is a devious yōkai who specializes in conning people. In The Great Yōkai Trial, he convinces several yōkai to put Kitarō before the Dai-Tengu on false accusations. In all adaptations, he is eventually found out and arrested by the Tengu Police.


In the fifth anime, Momonjii's appearance has very few changes. He still resembles a short bald old man with a round head and white hair pointing upwards on the sides of his head. He has fair skin with slightly visible hair on his chest and legs. His eyes are usually kept closed, when he does open them, they are revealed to lack any visible pupils. He wears a loose light purple kimono, exposing his chest, that is tied with a dull red obi, a pair dull green sandals and he also carries around a light brown staff that is taller than him.



5th Anime

Momon-Jii appears in episode 47 of the 5th anime adaption, The Great Yōkai Trial.


Genjutsu: He is able to create illusions with his genjutsu, or illusionary techniques. He must say certain phrases to activate his genjutsu, and it appears that anyone can say the phrase to activate it without Momon-Jii's permission as well.

  • Kitarō Monmon: Created by saying Kitarō Hana Mon Hana Monmon (Kitarō Nose Entity).
  • Momon-Jii Monmon: Created by saying Momon Hana Mon Hana Moge (Momon Nasal Motility).
    • Note: "Mon" is the colloquial/informal version of Mono, lit. thing or entity.
    • Note: "Moge" can be translated as "Motility" or the ability to move spontaneously.

Nose Hair Needles:



The momonjii of legend is born from a long-lived nobusuma, a yokai which was originally born from a long-lived bat. He takes the form of a hairy, bestial, old man who wanders the wilds and assaults passersby, particularly crying or misbehaving children. Momonjii appear late at night on the road, when the wind blows strongly, and those who meet them suddenly become very sick.
