Atooikozō (後追い小僧, Atooikozō) is a yōkai from Japanese folklore.
Atooikozō is a small child who is wearing animal fur and a mushiro hat who followers travelers. It is harmless and will disappear if the traveler gives it some food or talks to it. Some say it's a mass accumulation of children spirits.
