Known as a type of y\u014dkai, oni are believed to cause disease and disaster, and in some stories, they are the spirits of wicked humans transformed in <a href=\"https:\/\/en.wikipedia.org\/wiki\/Buddhism\" target=\"_blank\" rel=\"noopener\">Buddhist<\/a> hell.\u00a0<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Translation_and_Etymology\"><\/span><strong>Translation and Etymology<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The word oni comes from an old concept meaning \u201cto hide\u201d or \u201cconceal.\u201d In early Japan, before supernatural beings were clearly classified, \u201coni\u201d could refer to almost any fearsome entity\u2014spirits, ghosts, mysterious deities, or even cruel humans.&nbsp;<\/p>\n\n\n\n<p>Over time, its meaning narrowed to the terrifying, horned demons we know today. Interestingly, female demons in folklore are not usually called oni, but are known by a different name: kijo.<\/p>\n\n\n\n<p>Oni are often described as \u201cdemons\u201d or \u201cogres\u201d in Japanese folklore. They are closely tied to hell, punishment, and fear, but their role in culture is more complex than mere villainy.&nbsp;<\/p>\n\n\n\n<p>Oni are both bringers of calamity and cultural symbols that have endured through centuries, appearing in rituals, festivals, and traditional arts.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"900\" height=\"540\" src=\"https:\/\/kamicrew.com\/blog\/wp-content\/uploads\/2025\/10\/Translation-and-Etymology-of-Oni.webp\" alt=\"Translation and Etymology of Oni\" class=\"wp-image-581\" srcset=\"https:\/\/kamicrew.com\/blog\/wp-content\/uploads\/2025\/10\/Translation-and-Etymology-of-Oni.webp 900w, https:\/\/kamicrew.com\/blog\/wp-content\/uploads\/2025\/10\/Translation-and-Etymology-of-Oni-300x180.webp 300w, https:\/\/kamicrew.com\/blog\/wp-content\/uploads\/2025\/10\/Translation-and-Etymology-of-Oni-768x461.webp 768w\" sizes=\"auto, (max-width: 900px) 100vw, 900px\" \/><figcaption class=\"wp-element-caption\">Translation and Etymology of Oni<\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Habitat_and_Diet\"><\/span><strong>Habitat and Diet<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Tradition places Oni in remote, desolate places \u2014 mountains, caves, abandoned fortresses, and even islands shrouded in mystery. Within Buddhist cosmology, Oni also inhabit the underworld, serving as enforcers for the great King Enma, ruler of hell.<\/p>\n\n\n\n<p>Their diet is as grotesque as their nature. Oni are omnivorous but are especially known for devouring livestock, humans, and copious amounts of sake.
