We would particularly like to express our gratitude to Satō Shōzaburō of the Uesugi Museum, Endō Yasuhisa of the Yonezawa City Library (Local Materials Section), and Aoki Akihiro, Deputy Director of the Yonezawa City Library for their invaluable advice on primary materials relating to Yonezawa.

In addition, we have drawn upon the expertise of many colleagues while tackling this project. Anna Andreeva, Marc Buijnsters, and Wim Boot kindly provided feedback on translating and interpreting the religious aspects of the manuscript, while Ellis Tinios, Tim Screech, and Sasaki Takahiro generously offered comments on the images and manuscript. Ivo Smits and Niels van der Salm shared their wealth of knowledge on Heian-period poetry and other forms of poetic expression.
