Uda paper for backing of hanging scroll and repair paper of all art painting, which has been made in Yoshino, Nara Prefecture since ancient times, is pure Japanese tissue containing white clay made by crushing limestone in this region. This white clay has effects such as see-through, insect repellent, antioxidant action (burnt prevention), and maintenance of elasticity. In addition, it has a unique finish because it is made with bamboo blinds instead of bamboo blinds. Currently, only papers made in the " Kuzu area" of Yoshino are called Uda paper, Hon Uda, etc., and are distinguished from Uda papers made in other areas. It is the finest Japanese paper used for restoration of cultural properties.
