In recent years, a theory has emerged that the author was Yukinaga; who was Shimotsuke no Kami (governor of Shimotsuke Province), Jugoinoge (Junior Fifth Rank, Lower Grade) and a brother of Muneyuki; based on descriptions that are particularly mournful of Muneyuki HAMURO, who was a victim of the Jokyu War, and express disappointment at the conflict.
近年では、承久の乱で犠牲になった葉室宗行を特に悼み、さらに承久の乱により落魄したかのような記述から、宗行の兄弟である下野守従五位下行長を作者とする説もでている。
