The original copy existing today was written by Mitsumoto MAKABE (Jindayu) who was a descendant of Ujimoto MAKABE during the Genroku era in order to compile the history of the Akita domain and submitted to the head of Satake clan, the lord of the domain (Senshu Library owns the copy at present); therefore, the manuscripts stored at the Historiographical Institute at the University of Tokyo and books published today all originate with the original copy.
現存する本は元禄年間に秋田藩の藩史編纂のために真壁氏幹の末裔真壁充幹（甚太夫）が藩主佐竹氏に提出したもの（現在は千秋文庫所蔵）が唯一で、東京大学史料編纂所所蔵影写本及び現在の刊行本なども全てこれを元にしている。
