Orihon are accordion-style books, composed of a continuous folded sheet of paper enclosed between two covers. In comparison to scrolls these accordion books were more practical and allow enough space for writing similar to a scroll but in a compact form. They were used for Buddhist texts, journaling, poetry, and even yokai illustrations. Yokai is a catchall Japanese word for ghosts, demons, monsters, shapeshifters, tricksters, and other kinds of supernatural beings and mysterious phenomena.
