"The book includes materials on laws and justice collected and arranged by Fujiwara Michinori (Shinzei) (1108 -1159), which are important materials and allow us to know laws and social systems in the Heian era. This book, with colophon of Hojo Sadaaki in the 2nd year of Kagen （1304）, was formerly stored in Kanazawa library, and presented from the Maeda clan to the Edo Bakufu, the Feudal Government in the 7th year of Kyoho (1722). In the 30th year of Showa (1955), the book was designated as a important national cultural property. "
