These creatures are a representation of something evil or scary, and are bad spirits which tend to “hide” or “are hidden”.

Oni are a type of Japanese yokai, which means supernatural or strange creature.

Physical characteristics

Oni have one or two horns on their heads, and wear yellow shorts. They may be holding a golden rod or an iron club, and have sharp teeth.

They may also be presented as large and ogre-like.

Sometimes oni have three eyes instead of two.

These creatures do not go through physical transformations likevampiresorwerewolves. They are born as Oni, and usually live in caves of deep forests where humans seldom visit unless they get lost.

Oni are typically male, but there are also female Oni. Female Oni do not appear as frequently in traditional Japanese folklore, but have started to show up in various Japanese animation series. Female Oni are treated more as fantasy creatures which makes their impression less scary.


The origins of oni are rooted in Shinto and Buddhist beliefs, as well as in ancient Japanese legends and myths.

According to Shinto mythology, oni are born from the souls of wicked humans who are punished after death by being transformed into demonic beings. In Buddhist beliefs, oni are considered to be manifestations of negative human emotions such as anger, jealousy, and greed.

The earliest known depictions of oni can be traced back to ancient Japanese artwork from the 8th century, where they were often portrayed as fierce and menacing creatures with horns, fangs, and wild hair. Over time, oni became a common motif in Japanese art, literature, and theater, where they were often used as symbols of evil or as stock villains in folk tales and legends.

Today, oni continue to be a popular and iconic figure in Japanese culture, appearing in everything from manga and anime to video games and pop music. Despite their fearsome reputation, oni are also sometimes portrayed as comical or even lovable characters in modern media, and they remain a beloved and enduring part of Japanese folklore and mythology.
