Buruburu (震々, Buruburu) is a spirit that causes the shivers. It is drawn in a ghostly appearance of a woman in the book Konjaku Gazu Zoku Hyakki by Toriyama Sekien. But it is said that it can be divided into female and male. Buruburu also prefer children sometimes and they ambush in a dark place.
Buruburu are sometimes referred to as the spirit of cowardice. They follow people and cause them to shudder in fear.
Buruburu are born when humans perform acts of cowardice, such as running away from battle. They possess people by clinging to their shirt collars and touching the backs of their necks. This causes their hair to stand on end and sends shivers down their bodies.
The words "buruburu" and "zo" are Japanese onomatopoeia for the sound of shivering and the chill of fear. This spirit’s name comes from the sound of the shivers that it causes to run down people’s spines.
- In the 1968 and 1985 anime versions of "Gegege no Kitarō", Buruburu is a frost yōkai who attacks whoever by freezing them within. The only way to rid the victim (Nezumi-Otoko in the 1968 anime; Yumeko in the 1985 anime) of her is to place him/her in a hot onsen. Her true shape can not be seen by the naked eye, except with the help of special glasses. She obtains her appearance from "Konjaku Gazu Zoku Hyakki"
