A Quick Guide To The Demon Words

Most of the names below grow from a handful of words:

• 鬼 (oni): the classic horned ogre-demon
• 悪魔 (akuma): devil, the everyday word for a malevolent being
• 魔 (ma): demonic or evil, as in maō (demon king)
• 夜叉 (yasha): a fierce guardian spirit from Buddhist tradition
• 妖怪 (yōkai): the broad term for supernatural creatures and spirits

A small note on spelling: ō and ū mark long vowels, so Maō is pronounced mah-oh, held slightly longer on the o.

What is the difference between oni, akuma and yōkai?

Why do oni wear tiger skins and have horns?

Demons were believed to enter through the northeast “demon gate,” called ushitora (ox-tiger). That is why oni have an ox’s horns and a tiger-skin loincloth, and why this imagery appears in so many Japanese names meaning demon.
