Oboroguruma are ghostly oxcarts that have a face on them. On misty, moonlit nights, its squeaking wheels can sometimes be heard. If someone steps outside to find the source of the noise, they will find this parked outside their home.

FUN FACT: This is sometimes thought to be a type of tsukumogami, objects that have become haunted by spirits after existing for over a hundred years.

Examples in various media:

Oboro-Guruma (Nura: Rise of the Yokai Clan)

Oboro-Guruma, the Wheeled Mayakashi (Yu-Gi-Oh!)

Unnamed oboroguruma (Nioh 2)
