Koropokkuru are a race of small people in Ainu folklore. The name is traditionally analysed as a tripartite compound of kor or koro ("butterbur plant"), pok ("under, below"), and kur or kuru ("man, husband, person") and interpreted to mean "people below the leaves of the butterbur plant" in the Ainu language.
They're often depicted as holding a leaf as an umbrella.
