Good Yokai

A child who brings a house luck, and takes it when it leaves. A beast that eats your nightmares. A mermaid that Japan drew again in 2020. Here are the yokai that help, or do no harm.

Are there any good yokai? Yes. We went through the 217 yokai on this site. About one in seven helps people, or does no harm at all. Those are the ones on this page. The harmful ones outnumber them, 52 to 32.

Good does not always mean safe to ignore. A zashiki-warashi brings a house luck. When it leaves, the luck leaves with it. Cut down the old tree a kodama lives in, and misfortune follows. These spirits are kind to people who treat them well.

Others were called on for help. Amabie told people to copy its picture and show it to others, to keep disease away. In 2020, during COVID-19, people all over Japan drew it again. The baku was called after a bad dream, so it would eat the dream.

Many are just harmless. They lick dirt from a bath, follow your footsteps, or shout once from an empty house. They startle you, and that is all.

Old tools can go either way. Some come back angry at being thrown out. The ones here only want to play.

We only list a yokai here if its own page says it helps people, or does them no harm. Each page names the oldest source we found.

Yokai that bring luck

Keep them happy and the house does well. Some take the luck when they leave.

Protectors and charms

Called on against plague, nightmares, and trouble at the village edge.

Spirits of nature

A tree, a clear sky, a giant who shaped the land, a shrine bell. Treat them well.

Harmless: they only startle you

A voice, footsteps, a face. Then nothing happens.

Lickers and idlers

They lick grime, ceilings and lamp oil. Disgusting, not dangerous.

Tricksters and showmen

They fool you, play tricks or put on a show. Rarely anything worse.

Tools that came alive to play

Old household things with a face. These ones play rather than punish.
