In Japanese Buddhist belief, the Nio were two guardians of the Buddha. They are usually depicted as terrifying, muscular statues standing beside the entrance of Buddhist temples. One was named Agyo or Shukongoshin, who embodies manifest power or strength. He is depicted wielding a rod and is showing his teeth. The other was named Ungyo or Kongorikishi, who embodies latent power or strength. He is shown wielding a sword (or having no weapon) and has his mouth shut. Their scary appearance was meant to ward off evil spirits, thieves, and demons. Their role is security, to protect the faith and the visitors to the temples (practitioners of the faith), and thus lack the calm, serene expressions of figures seeking enlightenment. Nio is Japanese for "two kings".
