Nurarihyon or Nurihyon is a Japanese yokai (a supernatural monster in folklore) said to originate from Wakayama Prefecture. Nurarihyon is usually depicted as an old man with a gourd-shaped head and wearing a kesa robe. He is sometimes said to be leader of the yokai.

Nurarihyon will sneak into someone's house while they are away; drink their tea; and act as if it is his own house. Because it looks human; anyone who sees him will mistake him for the owner of the house; making it very hard to expel him. Nurarihyon is the leader of the Hyakki Yako Night Parade of 100 Demons.
