This article demonstrates that Fujiwara no Toshinori composed the text of the National Treasure Heike nokyo ganmon, which has usually been attributed to Taira no Kiyomori. First, the article establishes that Toshinori was a prolific author of the ganmon genre, which required skill in composing elaborate parallel prose and a profound knowledge of Buddhist doctrine and Chinese history. It then documents the existence of many, overlooked works written by Toshinori and reveals that certain passages found in them match passages in (...) the Heike nokyo ganmon, thus proving Toshinori’s authorship. It focuses in conclusion on Toshinori’s role in producing a picture scroll for the imperial court, a task precisely analogous to that carried out by his brother, the monk Joken, and suggests that Toshinori and his family may have been responsible for a good deal of the art created in the milieu of the retired emperor Goshirakawa.
