鬼

1. Origins, structure, and basic meaning

• Structure: 鬼 is read as おに and is a noun for an oni, the horned supernatural figure familiar from Japanese folklore.
• Basic usage: Use 鬼が住む for the creature itself and 鬼の面 for a mask representing its form.

2. Common pitfalls and similar expressions

• Limits of translation
  • English ogre or demon is an approximation and does not perfectly reproduce the cultural category of Japanese 鬼.
• Creature and representation
  • 鬼の面をかぶる means wearing a mask depicting an oni, not becoming the creature itself.
