Those who advocate the opinion that FUJIWARA no Yukinaga is the author claim that 'Shinano no Zenji is an error for Shimotsuke no Zenji,' while in Tsurezuregusa, the man is also called 'Shinano no Nyudo' (man with a shaven head) (variations of his name are Shinano no Zenji Yukinaga, Shinano no Nyudo, and Yukinaga Nyudo).
尚、藤原行長とする説では「信濃前司は下野前司の誤り」としているが、徒然草では同人を「信濃入道」とも記している（信濃前司行長信濃入道行長入道）。
