The Engishiki (an ancient book for codes and procedures on national rites and prayers) stipulated that a total of twenty thousand sheets of paper such as fushi (cloth made of paper threads), kokushi (paper made from paper mulberry tree), mashi (paper made from hemp), hishi (high-quality paper made from gampi tree), and kujinshi (paper made from sophora plant) should be produced, and delivered to Kuraryo (Bureau of Palace Storehouses) every year.
延喜式によれば、布紙・穀紙・麻紙・斐紙・苦参紙など毎年合わせて2万枚を漉いて内蔵寮に納める規定となっていた。
