Basically, Miyaza adopted the Roji system; members were divided into Wakashu (younger members), Churo (people around the age 50), and Otona or Toshiyori (leader of a village) in order of age and experience; in Otona, there were ranks from Ichiro (ichi osho), the general manager, to Niro (ni osho) and Sanro (san osho).
宮座は基本的には臈次制が採用され、年齢や経験などによって若衆・中老・乙名（大人・年寄）などの区分が見られ、更に乙名の中でも総責任者である一臈（一和尚）以下二臈（二和尚）・三臈（三和尚）などの序列があった。
