Abstract
A good part of paper for documents preserved in Shousouin at Nara is considered to have been made at Zushoryou, one of the Government offices in the Nara period. Outlines about the method of papermaking carried out at Zushoryou can be known by citing the literature Engishiki published in 927 AD. Four kinds of papermaking materials used at that time such as Kajinoki (Broussonetia papyrifera) Gampi (Wikstroemia sikokiana), Asa (hemp fiber string), Fu (hemp cloth) are investigated into the roles of their individual treating processes and flowsheets respectively. Among various processes carried out at Zushoryou, the sequence of fiber cutting and bruizing was found to be the most important invention created at Zushoryou.
