Generate oni names the way Japanese legend builds them: -dōji titles like Shuten-dōji and Ibaraki-dōji, mountain epithets, kijo and Gozen names for female oni, hell wardens, and hundreds of original horn-and-iron compounds for anime, tabletop and fiction.
About oni names
Oni are the horned, club-wielding ogres of Japanese folklore, and the famous ones are named like medieval nobles' pageboys. Shuten-dōji, the drunken lord of Mount Ōe, and his lieutenants Ibaraki-dōji, Kuma-dōji, Torakuma-dōji and Hoshikuma-dōji all end in -dōji (童子, child or page), a title that makes a monster sound both ancient and strangely youthful. Others carry the boyish suffix -maru (Ōtakemaru of Suzuka, Kidōmaru) or are simply known by their haunt: the oni of Rashōmon, Ura of Kibi, Onibaba of Adachigahara. Female oni, called kijo, are often court ladies turned demon and take courtly forms such as Suzuka Gozen, Momiji of Togakushi, Hashihime and Kiyohime.
Buddhist tradition adds the hell wardens Gozu and Mezu (ox-head and horse-head), the cannibal rasetsu and yasha, and the jaki crushed beneath the Four Heavenly Kings, so names built on Yasha-, Rasetsu-, Kishin- and Enma- sound properly infernal.
The original names here follow those patterns: a vivid root (tetsu iron, tsuno horn, kiba fang, rai thunder, beni crimson, kuro black) finished with -dōji, -maru, -bō or -hime, a mountain or gate used as an epithet, or a plain Japanese surname containing 鬼 for modern-setting oni characters.
Tips for choosing a name
- Give a powerful oni a -dōji name and tie it to a mountain or landmark (Ōeyama, Ibuki, Rashōmon); the epithet does as much work as the name itself in folklore.
- Use Gozen, -hime or the Kijo prefix for female oni, and give them a flower or season name (Momiji, Tsubaki, Yūgiri) to echo the court ladies they once were.
- Reserve -maru for young, reckless or servant oni and -bō for old, priestly or scholarly ones; numbered names like Tsunotarō and Kibasaburō work for a band of brothers.
- Match colour to temperament: aka (red) for rage and drink, ao (blue) for cold cruelty, kuro (black) for shadow and death, beni (crimson) for seduction and blood.
- For a modern-day oni, pick one of the real Japanese surnames written with the character 鬼, such as Onizuka, Kijima or Kitō, and pair it with an ordinary given name.
Frequently asked questions
What are the most famous oni names in Japanese mythology?
Shuten-dōji, king of the oni on Mount Ōe, and his retainer Ibaraki-dōji, whose arm was cut off at Rashōmon; Ōtakemaru of the Suzuka mountains; Ura, the Kibi oni behind the Momotarō legend; Gozu and Mezu, the ox- and horse-headed wardens of hell; and female oni such as Suzuka Gozen, Momiji, Kiyohime and the Onibaba of Adachigahara.
Why do oni names end in -dōji?
Dōji (童子) means child or page and was used for boy attendants in temples and noble houses. Medieval storytellers gave it to great oni like Shuten-dōji, partly because he was said to have been a beautiful temple boy before his transformation, and the title stuck as the standard way to name a lordly demon.
What is the difference between an oni and a yokai or a demon?
Yokai is the broad word for Japanese supernatural creatures; oni are one kind, the large horned, tusked ogres with iron clubs and tiger-skin loincloths. Western 'demon' is a loose translation: oni can be hell wardens, mountain bandits, vengeful humans or even protective figures, and a kijo is specifically a woman who has become an oni.
Can I use these oni names for an OC, D&D character or game?
Yes. Legendary names such as Shuten-dōji and Ibaraki-dōji are public folklore, and the original names on this page are free for personal and commercial projects. If you are writing for an existing franchise, check that it has not already given a major character the same name.
