Fan-shaped pieces of 'ryoshi' writing paper (the fan face), decorated with pictures, are folded in two, and joined along the fold to other pieces to make a booklet, into which sutras from Buddhist scripture such as the Hokekyo (Lotus Sutra), Muryo gikyo (Sutra of Immeasurable Meanings) and Kanfugenkyo (Samantabhadra Contemplation Sutra) were copied.
