Fudo (the Immovable One) is one of the powerful deities known as the Five Bright Kings in Japanese Buddhism and folk religion. As a manifestation of the central cosmic Buddha Mahavairochana (Japanese: Dainichi), Fudo is believed to protect Buddhism and its true adherents. Like all Bright Kings, Fudo assumes a frightening form, with a sword in his right hand and a rope in his left. He sits in front of a swiring flame of fire, with which he purifies evil. The left section of the flame is a modern replacement.
