Demon Slayer in Japanese kanji and meaning

Kimetsu No Yaiba written in Japanese lettersDemon Slayer/Kimetsu no Yaiba

What does Kimetsu no Yaiba mean in Japanese?

Are the English title “Demon Slayer” and the Japanese one “Kimetsu no Yaiba” the same meaning?


Almost the same! If I make a faithful translation, it would be “the edge for annihilating demons”.

As you know, the original title of Demon Slayer is “Kimetsu no Yaiba” in Japanese. What does each kanji letter mean? Let’s learn it together and understand the Demon Slayer world more deeply!


Ki written in kanji

Ki means a demon. This kanji also reads ONI which is a Japanese demon. Oni is a human style demon with horns on its head.

Typical Oni has red skin, two horns with yellow and black stripe, and a big mouth full of sharp fangs. And wears a pant made of tiger skin.

illust of Japanese demon ONI, This is ONI!


Metsu written in kanji

Metsu means to destroy and eliminate something. Not only defeat it, but there’s a nuance that trying to wipe out something completely out of this world.

The kanji character on the back of the Demon Slaying Corps swordsmen is exactly this one.


Yaiba is a blade or edge of a sword. So Kimetsu no Yaiba means the sword for elliminating demons = Demon Slayer.

Why don’t you PIN it?
