These masks are used exclusively in the ritual performance Okina 翁, also known as shikisanban 式三番. The hakushiki-jō (白式尉) and kokushiki-jō (黒式尉), white and black masks represent the right balance of yin and yang forces. The white hakushiki-jō represent the face of a benevolent deity in the form of an elderly man known as Okina. Its rustic counterpart, kokushiki-jō, is used to perform the role of Sanbasō, whose gestures are reminiscent of agricultural rituals.
