Kokushiki-jo: The sacred kokushiki or "black-styled" old man mask used by the Sanbaso character in the ritual play Okina. Note that the mask, like that of Okina, has facial hair and a hinged jaw. The role of Sanbaso is played by a kyogen actor. He dances a rite of exorcism in Okina; stamping and shaking a scepter filled with metal rings to purify the stage.
