Fudo Miyo-o, or Immovable King, is an incarnated figure of Dainichi Nyorai, or Cosmic Buddha.
The image is characterized by the fierce face to show his determination to destroy evil.

Commemorating the succession of the current (77th) head priest, one thousand Fudo myo-o, or Immovable King, images were donated by worshippers.
